Researchers demonstrate the first chip-based 3D printer

New Post has been published on https://thedigitalinsider.com/researchers-demonstrate-the-first-chip-based-3d-printer/

Researchers demonstrate the first chip-based 3D printer

Imagine a portable 3D printer you could hold in the palm of your hand. The tiny device could enable a user to rapidly create customized, low-cost objects on the go, like a fastener to repair a wobbly bicycle wheel or a component for a critical medical operation.

Researchers from MIT and the University of Texas at Austin took a major step toward making this idea a reality by demonstrating the first chip-based 3D printer. Their proof-of-concept device consists of a single, millimeter-scale photonic chip that emits reconfigurable beams of light into a well of resin that cures into a solid shape when light strikes it.

The prototype chip has no moving parts, instead relying on an array of tiny optical antennas to steer a beam of light. The beam projects up into a liquid resin that has been designed to rapidly cure when exposed to the beam’s wavelength of visible light.

By combining silicon photonics and photochemistry, the interdisciplinary research team was able to demonstrate a chip that can steer light beams to 3D print arbitrary two-dimensional patterns, including the letters M-I-T. Shapes can be fully formed in a matter of seconds.

In the long run, they envision a system where a photonic chip sits at the bottom of a well of resin and emits a 3D hologram of visible light, rapidly curing an entire object in a single step.

This type of portable 3D printer could have many applications, such as enabling clinicians to create tailor-made medical device components or allowing engineers to make rapid prototypes at a job site.

“This system is completely rethinking what a 3D printer is. It is no longer a big box sitting on a bench in a lab creating objects, but something that is handheld and portable. It is exciting to think about the new applications that could come out of this and how the field of 3D printing could change,” says senior author Jelena Notaros, the Robert J. Shillman Career Development Professor in Electrical Engineering and Computer Science (EECS), and a member of the Research Laboratory of Electronics.

Joining Notaros on the paper are Sabrina Corsetti, lead author and EECS graduate student; Milica Notaros PhD ’23; Tal Sneh, an EECS graduate student; Alex Safford, a recent graduate of the University of Texas at Austin; and Zak Page, an assistant professor in the Department of Chemical Engineering at UT Austin. The research appears today in Nature Light Science and Applications.

Printing with a chip

Experts in silicon photonics, the Notaros group previously developed integrated optical-phased-array systems that steer beams of light using a series of microscale antennas fabricated on a chip using semiconductor manufacturing processes. By speeding up or delaying the optical signal on either side of the antenna array, they can move the beam of emitted light in a certain direction.

Such systems are key for lidar sensors, which map their surroundings by emitting infrared light beams that bounce off nearby objects. Recently, the group has focused on systems that emit and steer visible light for augmented-reality applications.

They wondered if such a device could be used for a chip-based 3D printer.

At about the same time they started brainstorming, the Page Group at UT Austin demonstrated specialized resins that can be rapidly cured using wavelengths of visible light for the first time. This was the missing piece that pushed the chip-based 3D printer into reality.

“With photocurable resins, it is very hard to get them to cure all the way up at infrared wavelengths, which is where integrated optical-phased-array systems were operating in the past for lidar,” Corsetti says. “Here, we are meeting in the middle between standard photochemistry and silicon photonics by using visible-light-curable resins and visible-light-emitting chips to create this chip-based 3D printer. You have this merging of two technologies into a completely new idea.”

Their prototype consists of a single photonic chip containing an array of 160-nanometer-thick optical antennas. (A sheet of paper is about 100,000 nanometers thick.) The entire chip fits onto a U.S. quarter.

When powered by an off-chip laser, the antennas emit a steerable beam of visible light into the well of photocurable resin. The chip sits below a clear slide, like those used in microscopes, which contains a shallow indentation that holds the resin. The researchers use electrical signals to nonmechanically steer the light beam, causing the resin to solidify wherever the beam strikes it.

A collaborative approach

But effectively modulating visible-wavelength light, which involves modifying its amplitude and phase, is especially tricky. One common method requires heating the chip, but this is inefficient and takes a large amount of physical space.

Instead, the researchers used liquid crystal to fashion compact modulators they integrate onto the chip. The material’s unique optical properties enable the modulators to be extremely efficient and only about 20 microns in length.

A single waveguide on the chip holds the light from the off-chip laser. Running along the waveguide are tiny taps which tap off a little bit of light to each of the antennas.

The researchers actively tune the modulators using an electric field, which reorients the liquid crystal molecules in a certain direction. In this way, they can precisely control the amplitude and phase of light being routed to the antennas.

But forming and steering the beam is only half the battle. Interfacing with a novel photocurable resin was a completely different challenge.

The Page Group at UT Austin worked closely with the Notaros Group at MIT, carefully adjusting the chemical combinations and concentrations to zero-in on a formula that provided a long shelf-life and rapid curing.

In the end, the group used their prototype to 3D print arbitrary two-dimensional shapes within seconds.

Building off this prototype, they want to move toward developing a system like the one they originally conceptualized — a chip that emits a hologram of visible light in a resin well to enable volumetric 3D printing in only one step.

“To be able to do that, we need a completely new silicon-photonics chip design. We already laid out a lot of what that final system would look like in this paper. And, now, we are excited to continue working towards this ultimate demonstration,” Jelena Notaros says.

This work was funded, in part, by the U.S. National Science Foundation, the U.S. Defense Advanced Research Projects Agency, the Robert A. Welch Foundation, the MIT Rolf G. Locher Endowed Fellowship, and the MIT Frederick and Barbara Cronin Fellowship.

Capacitor: It has two terminals to store electrical energy in an electric field

Resistor: This electronic component regulates the flow of electric current.

Inductor: It is a conducting coil introducing inductance into a circuit.

Transistors: It is a semiconductor devices capable of amplification.

Diode: It is a semiconductor device consisting of a p-n junction.

PCB types

Electronic goods may comprise circuit board types based on their applications and functions. They can be of different shapes, sizes, and designs suitable for the product. The most common PCB types include:

Single-sided PCBs with only one layer of copper foil and an alloy case protecting the board.

Multilayer PCBs are versatile for rigid and flexible parts of the product. They usually have supporting layers on the configuration's sides, top, and bottom.

Rigid-Flex PCBs keep the board from moving and twisting when inserting multiple wire fittings into the circuit.

Companies developing electronic goods must choose the circuit board specially designed for the product. Find leading manufacturers of PCBs that offer integrated circuits with automated decapsulation to meet recommended criteria.

Features of a PCB board

A two-layer PCB board is considered the simplest way to produce. These boards feature a copper layer on both of their sides as outer layers. Boards that have multiple layers will usually have a sandwich of extra interior copper layers as well as the required insulation to protect the circuits from surge voltages.

After a two-layer PCB, the next most convenient and easiest way to produce is the four-layer board. These electronic circuit boards are capable of adding a considerable amount of routing options in the inside layers when compared to those of two-layer boards. Some piece of these inside layers is suitable to use as a power plane or ground plane.

The reason for using some inside layers as a power plane or ground plane in a printed circuit board is to attain the following benefits, such as:

Improved signal integrity

Lower EMI

Higher signaling frequencies

Enhanced power supply decoupling

Through Hole components in a circuit board are mounted by the wire leads, which are passing through it. They are soldered to outlines on the other side of the board. Surface mount components of the board are connected to their leads to copper outlines on the same side of the board. A printed circuit board may use both techniques for mounting electronic components.

In PCB manufacturing, most companies do not prefer to use the Through Hole method during their manufacturing process. Most manufacturers use only Surface Mount method for mounting various electronic components, including:

Diodes

Transistors

IC chips

Capacitors

Resistors

However, they use this method to mount some large electronic components, like electrolytic connectors and capacitors.

Artwork is a pattern, which is used to etch into each copper layer of a printed circuit board. Manufacturers use photoresists to etch a circuit board, and layer onto it. The light is then projected to the etched part of the board in the artwork pattern.

The opposed material will safeguard the copper PCB printing from closure into the etching solution. The etched circuit board is then sanitized and cleaned. In boards that contain multiple layers, the material layers are laminated jointly in an alternating sandwich, such as copper, substrate, etc. The external layers of the board are only to be coated, as the nearby substrate layers will protect the inside copper layers.

All types of printed circuit boards will undergo a PCB prototype process before their manufacturing process. This is for the reason that it will aid manufacturers to find out a variety of flaws effectively. If you are designing a circuit board, the process will aid you considerably in having a performance-centric board.

The lights in an LED PCB will also need a circuit board because it plays a vital role in supporting LED lighting. It backs the LEDs physically by conducting heat from the LED bulbs. It, in turn, improves the performance of the bulbs, in addition to inhibiting them from excess heating.

A Rigid Flex PCB is largely used in industrial, commercial, and martial applications. They are also used in a variety of devices, ranging from cell phones to digital cameras to smart devices,. As these PCBs are frivolous in design, they are used to make pacemakers in the medical industry because of their space-saving and flexible design, as well.

PCB assembly for dummies: A step by step guide to getting PCB assembly right

Before many years, food, shelter & water were the essential part for an individual in their day to day lives, but now one major factor is added that is electronics. Our day starts with electronic components and ends with the same, from our phones to our cars to our home appliances. And the most essential part of these electronics is the printed circuit board (PCB).

What is PCB?

So you may have come across the small green chips may be in your phone, or say TV remote covered with copper parts and lines, these tiny green coloured chips are PCB, & they form the heart of that particular electronic device.

The output of the green colour:

The PCB comprises of copper lines, fiberglass, and other metal parts, and these boards are joined together with epoxy and insulated with a solder mask. And from this solder mask, the green colour comes from.

You may have also observed these boards with components firmly stuck on it and for an advanced PCB to work efficiently, the components should be perfectly mounted on it. And a PCB with organised components on it is called an assembled PCB. And the process of manufacturing is called PCB assembly or PCBA.

Do you have any idea about how these devices are made? The process of PCB assembly is an easy one but has many manual and automated steps. Every step, the manufacturer has an option to select from an automated and manual process. Yeah, this is quite confusing, to let’s make this easier and have a look at the below steps from the initial stage to the end with a brief explanation.

The PCBA Process steps:

1. Solder Paste Stencilling

So the processing of the PCB assembly starts with applying a solder paste to the board. It’s similar to the process of screen printing, wherein a thin stainless steel layer of the stencil is placed over the PCB. The assemblers apply the solder paste only to fixed parts of the future PCB, &only the components will be placed when the PCB is completed.

Image Source: https://www.pcbcart.com

So the solder paste is to be applied evenly on the circuit board, and also in the intended locations where it should be needed. 

2. Pick and Place

Once you have applied the solder paste to the PCB board, the process of PCBA is taken to a further step and that is the pick and place one. The PCB board is picked with a vacuum grip and placed on a machine and a surface mount components or SMDs are applied on the prepared PCB with the help of a robotic device. And in the later stage, these SMDs are soldered on the surface board.

Before the invention of machines, this step was manually done with the help of tweezers, & here the assemblers had to pick and place all the components with hands. But thanks to the machines, to make them work for the humans quite simpler and easy.

3. Reflow Soldering

Now when the solder paste and SMD have been placed, they also have to be solidified, to keep the paste and components to remain in their place. And the PCB assembly is skilled through a process called “reflow”.

After the completion of the Pick & Place process, the PCB board is shifted to a conveyor belt. The belt takes the PCB board to a large reflow oven, the oven has many inbuilt heaters & these heaters in turn heats the board to the temperature to around 250 degrees Celsius. The solder is melted into the solder paste with the immense heat in the oven.

As the solder starts to melt, the PCB moves through the oven and is passed through coolers, and this cools the melted solder and solidifies in a controlled manner. And in the end the SMDs are connected to the PCB with the creation of a permanent solder joint.

4. Inspection and Quality Control

Once the reflow process is done, we need to check the quality and conduct an inspection, and at this time the mount components are already soldered into a place. This assembled board is inspected for knowing the functionality.

Manual checks: This is done by an assigned designer, who visually ensures the quality and functionality of a PCB.

Though you come across any mistake or not, you need to carry on the next step that is to check the part and ensure the working of the same as required it to be. This means you have to check the PCB connections for quality purposes. You can carry out these inspections on regular basis to have an error-free working of the board.

5. Through-Hole Component Insertion

Once we pass the inspection stage, the board may add on more components apart from the SMDs, and this includes the plated through-hole components or can be said PTH components.

To explain PTH, it can be said that it is simply a hole in the PCB which is fully plated through the board. Now through these holes, PCB components pass the signal from one side to the other side of the board. And the soldering paste will be not the preferred one, in this case, instead, we need a step higher soldering method for the PTHs. There are mainly two main soldering methods:

Manual Soldering: This is completely manual, through-hole insertion

Wave Soldering: This can be said to be the machinery form of soldering, but with a little different process. Here the PTH component is put in place and the board on the other conveyor belt. The waves of the molten solder are washed from the downwards side of the board at a stroke, and this process is undertaken with the help of the oven specially meant for this process. 

6. Final Inspection and Functional Test

The last step is the final inspection which tests the PCB regarding its functioning. This is known as the “functional test”. How the PCB is operated in normal situation is tested here by putting the PCB going through many paces. Simulated signals & power pass through the PCB during the test and the electrical characteristics of the PCB are tested.

If any problem faced in the current or signal output, voltage, or any unacceptable fluctuation occurs, then the PCB fails the test. This failed PCB can be later recycled or whatever are the company laws.

But testing is one of the step not to be missed in the PCB assembly process,as the pros and cons is decided in this stage only.

So widely choose your PCBA manufacturer like Jayshree Instruments that delivers the best services and assuring PCB assembly process meets the high quality standards and work.

 The Impact of PCB Assembly on Miniaturization

In the early days of personal computing, computers were massive machines that occupied entire rooms. They had limited processing power and were mainly used for complex calculations and data processing. Users interacted with them through punch cards and command-line interfaces.

Now, fast forward to the present day, where personal computers have undergone a remarkable transformation. Today's computers are sleek, powerful devices that can fit on a desk or even in your backpack. Moreover, these modern computers are not just tools for number crunching. They are multimedia powerhouses & provide access to the vast expanse of the internet, enabling communication, research, and information sharing.

A Deeper Dive into PCB Miniaturization

The process of miniaturization in electronic devices involves condensing more transistor nodes onto smaller integrated circuits (ICs). Once integrated, these ICs become part of a system or device, enabling it to perform its intended function. This technology achieves a remarkable combination of reduced size and increased power.

The evolution of miniaturization aligns with Gordon Moore's foresight in 1965, predicting that integrating more components onto ICs would lead to innovations such as home computers, automotive controls, and portable communication devices. Moore's prediction materialized, ushering in an era of technological advancements, including portable computers, smartphones, medical devices, the Internet of Things, 5G wireless devices, as well as AR/VR and AI—all made possible by smaller yet more powerful computing systems.

While envisioning these miniature technologies is one aspect, the manufacturing process presents its own set of challenges. Electronics manufacturers continually innovate to overcome these challenges and fulfil the promises of miniaturization.

Miniaturization holds the potential to revolutionize the world, but realizing this potential requires advanced manufacturing processes, such as advanced electronics assembly. It involves a meticulous blend of expertise, precision, and innovative processes to transition from conceptualization to mass production and global distribution.

Evolution of Miniaturization

A notable miniaturization technique involves using Ball Grid Arrays (BGAs) for integrated circuit packages. BGAs facilitate numerous connections between the integrated circuit and the printed circuit board, enhancing signal routing and processing power. They also contribute to chip reliability and heat reduction, making them integral to technology miniaturization.

Miniaturization with Advanced PCB Assembly

Additionally, wafer-level chip scale packages (WLCSPs) play a role in miniaturization by creating micro-scale ICs on a wafer, which are later diced into individual chips. These packages, often featuring gold joints, maintain reliability even at tiny scales, enabling downsizing without compromising performance. The Chip-on-Board (CoB) process is another crucial element in advanced electronics assembly, involving the specialized attachment of integrated circuit chips to substrates. This process becomes particularly intricate as the size and shape of ICs and substrates vary significantly among different products.

The Road Ahead

In essence, miniaturization holds the promise of addressing significant global challenges, from extending human life to powering cleaner energy solutions. Advanced electronics assembly acts as the bridge between groundbreaking research and consumer accessibility, enabling seamless transitions from prototypes to production, regardless of the complexity or size of the electronics involved. Whether a startup or a Fortune 500 technology leader, we offer advanced PCB assembly services that ensures a smooth journey.

All about transparent, colorless polyimide film

Polyimide film is an electrical insulating material with very special properties and can therefore be used in a variety of ways. Polyimide (short: PI) is a thermoplastic synthetic substance for high-temperature applications.

Polyimide foil is dimensionally stable, has a very high dielectric strength and is also HF-compatible as an adhesive-free foil. The polyimide foil is often made self-adhesive.

We would like to provide you the most important information about polyimide foil.

What is a polyimide?

A polyimide is a class of polymers and can be used in many different ways. Good examples are thin foils that are used for flexible cable insulation and also for printed circuits. They are also used as fibers for fire protection clothing or in the form of rigid foams for the insulation of aircraft and ships.

Polyimides have practical electrical properties, are chemically very stable and retain their mechanical characteristics even at high temperatures.

Typically, polyimides have a characteristic orange-brown color. This can be seen very well, for example, in rigid printed circuits, for instance in televisions, radios, cell phones and other electronic devices. Since the parts made of polyimide cannot be seen here, the color does not matter in contrast to visible displays.

Which are the components of the polyimides?

In principle, polyimides consist of two essential building blocks. These are diamines and dianhydrides. Diamines are organic compounds and have two amino groups. Dianhydrides have two double carboxylic acid anhydride groups.

Both ingredients tend to be very aromatic. In addition, they have a strong absorption in the UV range, which goes into the visible part of the spectrum. This gives the polyimides their characteristic color.

The aim of research in recent years has been to investigate the combination of the two components in order to determine their advantages for creating a colorless polyimide. Ultimately, the goal was achieved, and colorless polyimides were created.

What is meant by colorless?

First of all, you have to be aware that “colorless” can mean different things and that there are actually two different factors that can explain colorlessness:

Definition by the so-called Yellowness Index (YI). It is a scale on which e.g. a normal drinking glass has a YI of zero. A typical polycarbonate foil would have a YI of 0.5 and a normal polyimide foil would be around 90. Currently, the goal for so-called colorless polyimides is around 2.

The second option is transparency. This physical property provides information about how much light is transmitted through a material without being scattered. On the one hand, transparency is defined by the permeability, i.e. how much light of a certain wavelength passes through the material without it being scattered. On the other hand, the haze defines the amount of light scattered in the material. Scotch tape, for example, is colorless, but has a clear cloudiness. The polyimide foil is orange, but still transparent. The drinking glass is both colorless and transparent.

What are the advantages of colorless polyimides?

The advantages of the colorless polyimide foil are very versatile, which is why the material offers important possible uses:

high light transmission

high temperature stability

excellent surface hardness

smooth surface

Resistance to acids and bases

moisture barrier

Resistance to radiation

easy further processing

Where are colorless polyimides used??

As already indicated, polyimides are versatile due to the excellent combination of useful properties. Polyimides are particularly often used in the electronic field in aerospace, in automobile construction, in consumer electronics and in other high-technology areas. As far as the colorless variant is concerned, it is predicted that it will be used primarily in the high-tech sector. It is important that the correct combination of the blocks is achieved in order to get an optimal result. The main application areas are according to experts:

smartphones

photovoltaic cells

medical applications

Smartphones are simply indispensable in our lives. The glass displays in particular often cause headaches because they are still quite prone to breakage, or at least are at risk of cracks and chipping. In addition, the glass of the display brings with it quite some weight, which has a negative effect on the total weight of the cell phone. With smartphones, the tendency is rather that the phone is large, since it is not only used for making calls, but also for googling, for all kinds of apps and so on. Therefore, the weight issue is crucial.

A smartphone that is significantly lighter with the same size and functionality has a clear competitive advantage. This can be achieved by completely or partially replacing the glass display with foil. The haptic is also tactile, the display of high quality, of course completely colorless. The additional advantage is that the display does not break even with heavy impacts and when falling.

Glass cover plates are often used together with photovoltaic cells to protect the sensitive circuits inside. Here, too, the weight of the glass is a negative factor, since this requires a more complex attachment, or possibly exceeds the load-bearing capacity of the roof on which the photovoltaic cells are to be installed. In addition, there is of course also a risk of breakage, especially if there are tall trees nearby, the branches of which could fall onto the solar system in stronger winds. The new polyimide technology is also an excellent option here, since it effectively protects photovoltaics – and with significantly less weight and without the risk of glass breakage.

There are also many possible applications in the medical field. For example, one has to think of tubes for the administration of medication, since these require excellent optical quality, should be light in weight, must offer thermal stability and, moreover, must meet high hygiene standards.

Is polyimide foil currently being produced from colorless, transparent polyimide?

Nowadays, transparent polyimide foil can also be produced from the commercially available polyimide. This is available in different thicknesses:

0,025 mm

0,05 mm

0,075 mm

Is it possible to die cut the transparent polyimide film?

All common processing methods for foils can also be used for the colorless polyimide foil. In any case, this also includes punching the foil.

Can a coating be applied to the transparent polyimide foil?

The polyimide foil can be processed so that it is self-adhesive. It can therefore be provided with different coatings depending on the different requirements of the customers. There are different adhesive systems to choose from.

Why is the market potential for transparent polyimide foil so big?

Colorless polyimides are a breakthrough technology and are being discussed for use in numerous modern consumer and communication electronics products. Virtually all major electronics manufacturers are currently working on folding displays. Samsung and Huawei even have devices on the market and Apple is working intensively on the project.

Another promising area of application for transparent polyimide foil is as flexible substrates for optoelectrical components. In this context, for example, flexible organic light-emitting display devices with active matrix (AMOLEDs), flexible printed circuit boards (FPCBs) and flexible solar cells should be considered.

The great advantage is that the displays made possible by the colorless polyimide foil can be rolled up and transported easily. They are light, space-saving, robust and have tactile properties.

Is transparent polyimide foil commercially available?

More and more companies are interested in the commercial production of practical, polyimide-based displays. In the meantime, some companies have established secure supply chains and the scale-up of production is managed while ensuring sustainability. It can be expected that the number of companies will increase significantly due to the innovative product, for which there is clear demand.

However, it must also be pointed out that – as with any new technology – the initial costs will be high, which is why it is likely that high-end products will be equipped with the new technology in a first stage.

Dr. Dietrich Müller GmbH supplies transparent polyimide film Flexiso PI FI 16075 in the thickness of 0,013, 0,025 and 0,050 mm.
