things i learned this year on wikipedia: you can microwave metal actually

there is an ancient (ANCIENT) microwave in my work breakroom. you could fit an entire turkey in there. there's no turntable, if your food ends up uneven that's on you. And, most mysterious of all: it has a metal rack in the center of the microwave.

(example image from wikipedia)

after spending 4 years at this place avoiding the Big Microwave and its Probable Death Rack i finally went on wikipedia and made a discovery. I had been lied to my entire life. You can put metal in the microwave.

It's the shape that gets you, not just the material. It's just that you can only put things without points in the microwave, which rules out almost all metal items you were potentially thinking of microwaving. Unless you have a metal orb at home. that might be okay. Quothe wikipedia:

Contrary to popular assumptions, metal objects can be safely used in a microwave oven, but with some restrictions.[77][78] Any metal or conductive object placed into the microwave oven acts as an antenna to some degree, resulting in an electric current. This causes the object to act as a heating element. This effect varies with the object's shape and composition, and is sometimes utilized for cooking. Any object containing pointed metal can create an electric arc (sparks) when microwaved. This includes cutlery, crumpled aluminium foil (though some foil used in microwave ovens is safe, see below), twist-ties containing metal wire, the metal wire carry-handles in oyster pails, or almost any metal formed into a poorly conductive foil or thin wire, or into a pointed shape.[79] Forks are a good example: the tines of the fork respond to the electric field by producing high concentrations of electric charge at the tips. This has the effect of exceeding the dielectric breakdown of air, about 3 megavolts per meter (3×106 V/m). The air forms a conductive plasma, which is visible as a spark. The plasma and the tines may then form a conductive loop, which may be a more effective antenna, resulting in a longer lived spark. When dielectric breakdown occurs in air, some ozone and nitrogen oxides are formed, both of which are unhealthy in large quantities.

Tips to design High Frequency PCB for optimal performance

Best Practices for High-Frequency PCB Design

We all know the importance of military electronic devices like military radars, satellite systems, communications, etc, for the safety of our country. But do you know that these systems consists of high-frequency Printed Circuit Boards? Therefore, a high-frequency printed circuit board (PCB) requires careful design to guarantee the best performance. As a PCB producer or user, you must know that even little errors can have a big effect on performance.

Here, in this insightful blog, we will discuss negotiating the challenges of high-frequency PCB design so that your product development project performs as intended.

Understanding the Basics

It is essential to understand why high-frequency PCBs need particular care before going into the details. Signals can deteriorate at high frequencies for reasons including crosstalk, signal reflection, and impedance mismatches. PCB design guidelines are helpful in reducing these problems and guaranteeing the effective operation of your printed circuit board.

Key Design Considerations

These super-critical High-Frequency Printed Circuit Boards need several careful considerations at every stage, from the design to production. Here are some noteworthy points to keep in mind.

Material Selection

Maximizing the performance of your PCB starts with selecting the appropriate material. FR4, Rogers, or Teflon (PTFE) are common materials used in high-frequency PCBs and have distinct

advantages:FR4: Lower dielectric losses but more expensive

Rogers: Consistent high-frequency performance with reduced dielectric losses.

Teflon or PTFE: Excellent performance, yet processing is more difficult and costly.

Picking the right material will depend on the specifications and budget of your project.

Layer Stack-Up

Your PCB's layer stack-up affects signal integrity. Signal integrity is improved, and loop regions are reduced when power and ground planes are close to signal layers. With the balanced layer stacking, electromagnetic interference (EMI) can be reduced in high-frequency designs.

Impedance Control

High-frequency PCB design depends critically on maintaining constant impedance. Mismatched impedance often results in lost and reflected signals. Controlled impedance traces are computed using the material's dielectric constant, trace width, and height. There are tools and software accessible to assist you in creating and validating impedance-controlled traces.

Being one of the market leaders in the PCB manufacturing industry, we at PCB Power apply these considerations to produce advanced high-frequency printed circuit boards.

Practical Tips for High-Frequency PCB Design

Here are some simple yet effective practical tips that can improve your PCB performance.

Using Shorter Trace Lengths: A shorter trace length can help reduce signal deterioration. Long traces can function as antennas, absorbing noise and producing EMI problems. Reduce the distance high-frequency signals must travel over the PCB.

Avoid Sharp Bends: Impedance alterations and signal reflection are two effects of abrupt bends in traces. To maintain signal integrity, use 45-degree angles or gentle curves rather than 90-degree turns.

The Right Grounding: It takes a strong grounding plan. To reduce noise and performance enhancement, use a ground plane to give signals a return route. Narrow ground traces are to be avoided since they can cause inductance and lower signal quality.

Advanced Techniques:

With technological advancement, new and modern techniques are implemented for high-frequency printed circuit board manufacturing.

Via Placement

High-frequency signals can be impacted by parasitic inductance and capacitance. To reduce the effect, use vias sparingly and put them thoughtfully. Use several vias to disperse the current equally as needed.

Differential Pair Routing

Differential pair routing helps lower noise and crosstalk for fast signals. Signal integrity must be preserved by routing differential pairs closely together with identical lengths.

Testing and Validation

Test and validate your high-frequency PCB thoroughly after it is designed. Test impedance and signal integrity with Time Domain Reflectometry (TDR) and Vector Network Analyzers (VNA). Furthermore, simulation software is highly useful for predicting PCB performance under different circumstances.

FINAL WORDS:

High-frequency printed circuit board design calls for meticulous attention to detail and following particular PCB design standards. High-frequency applications can be optimized on your PCB by choosing the appropriate materials, keeping impedance control, and putting in place efficient grounding and routing techniques. To be sure your design satisfies performance objectives, never forget the need for extensive testing and validation.

By using these tips, you can confidently take on the difficulties of high-frequency PCB design and guarantee that your projects meet the best possible performance and dependability criteria.

5G Radome Extrusion Machine

The function of radome is to protect the antenna system from the influence of external environment (such as wind, snow, sunlight, biology, etc.), prolong the service life of antenna, and ensure the permeability of electromagnetic wave. Therefore, the radome material shall meet the requirements of dielectric performance, mechanical performance, weather resistance, manufacturability and weight. On this basis, the requirements for 5g radome are as follows 1. Low dielectric and low loss While the radome plays a protective role, the dielectric properties of the material will also directly affect the performance of the antenna. The absorption and reflection of electromagnetic waves by materials will reduce the signal transmission efficiency. Therefore, radome materials need to adopt materials with low dielectric constant and low dielectric loss, and millimeter waves are easier to be lost, so the requirements for dielectric properties of materials are higher. At present, it is urgent to develop low dielectric and low loss materials for radome. 2. Lightweight The radome is usually made of fiber reinforced resin composites. At present, the radome is mainly made of FRP, but the proportion of FRP is large, which is not conducive to the lightweight design of the antenna.

Therefore, in order to meet the design needs of lightweight, integration and miniaturization of 5g antenna, radome materials will also develop to lightweight. 3. Environmental protection In recent years, with the enhancement of people's awareness of environmental protection, the requirements for environmental protection at home and abroad are higher and higher. Environment-friendly is the higher requirements of 5g for radome materials. Enterprises actively research and develop low dielectric and low loss reinforced and modified materials with high cost performance, environment-friendly and lightweight, such as ASA, PP, PC and other materials With the advent of 5G era, the fast development of radome for base-station protection is promoted with material and related equipment.

What is Rogers PCB?

Rogers PCB is a type of printed circuit board (PCB) material made from a combination of epoxy and ceramic. It is well known for its high dielectric constant, low loss tangent, and high thermal conductivity, making it an ideal material for high-frequency applications. It is used in a wide range of electronics, such as:

5G Station

Cellular Base Station Antennas and Power Amplifiers

Automotive Radar and Sensors

Microwave point to point (P2P) links

LNB’s for Direct Broadcast Satellites

Microwave equipment of all kinds.

RF Identification (RFID) Tags

Rogers PCB is produced using the raw materials of the Rogers Company. Rogers company manufactures the laminate materials that are often used for manufacturing circuit boards. The Rogers PCB is a type of high-frequency PCB board, quite different from the traditional PCB board materials, epoxy resin. It uses the ceramic base as the material of high frequency. The major advantage of Rogers PCB is the temperature stability and superior dielectric constant.

Rogers PCB has a major application in high-speed electronic designs, radio frequency applications, and commercial microwaves. The low water absorption capacity of this Rogers PCB is ideal for the application of high humidity. Other Rogers PCB applications include RF identification tags, power amplifiers, automotive radar, sensors, etc.

Rogers PCB fabrication needs in-depth research on high-frequency PCB. HITECHPCB is a Rogers PCB manufacturer and has a deep understanding of the performance of Rogers PCB material. For example, Rogers PCB laminates and Rogers PCB dielectric constant in Rogers PCB material properties Rogers PCB is a high-frequency PCB material model produced by Rogers company, different from the conventional FR-4 PCB material. There is no epoxy resin in the Rogers PCB material, and Rogers ceramic PCB is used as the High-frequency PCB material. Absorption of Rogers PCB, it can be used as an ideal choice for application ns in high humidity environments, providing customers in the high-frequency PCB industry with the highest quality.

Difference Between Rogers Materials and FR-4 Materials

By combining Rogers PCB layers with FR-4 layers, we can achieve reduced cost and maximum performance compared to if we used only Rogers layers. Thus, this process should use Rogers PCB cores instead of prepregs for this process.

FR-4 stack up with 6 layers is shown below. Because prepreg is less expensive than cores, it is placed on the outside to minimize cost. A foil build is often referred to as this.

Rogers layers are required on the outside layers, but the core is usually found on the layers that need them. Below is an example with 6 layers but with 3 cores instead of 2. This configuration is sometimes called a "core build" or "cap construction" board. Rogers PCB is a high-frequency circuit board that has ceramic laminates and reinforced hydrocarbon. A Rogers PCB may be made from cores and prepregs, but most often, the top two copper layers are carried on the core, while the rest of the board is made from standard FR-4 to reduce the cost. The PCB materials absorb the signal, due to which it has less signal loss compared to that of FR-4. At higher frequencies, the signal loss is greater in FR-4 materials. This is also the signal length and design dependent.

High-Frequency

PCB with FR-4 materials is preferred due to their low cost, reliability, and well-understood electrical and mechanical properties. They are used in various applications ranging from microwave designs to audio circuits. Unfortunately, FR-4 printed circuit boards are not suitable for high-frequency applications. Rogers created the most well-known high-frequency-special laminates. Its materials have a constant dielectric reduction of close to 20% when compared to FR-4 printed circuit boards.

The best way to determine whether your project will benefit from high-frequency laminates is to assess electrical and mechanical requirements. If you find both variations are too broad, Rogers PCB material is a better option.

Dissipation

The material used is most important when producing printed circuit boards, though it may require a high cost. However, it is not the only issue that knows the content value when it comes to the loss factor or Df. FR-4 printed circuit boards will be affected or reduced. The losses are greater when compared to printed circuit boards made from Rogers materials.

In other words, when compared to Rogers PCB, FR-4 materials have a higher dissipation factor, especially at high frequencies. Typical values for FR-4 printed circuit boards are around 0.020 and close to 0.004 for Rogers boards. Dissipation of FR-4 materials increases with frequency. High-frequency laminates primarily have a frequency-dependent stable dissipation characteristic.

The signal loss is minimized with the lower dissipation factor in FR-4. Also, the automated assembly process and the processing of FR-4 materials make them easier in the assembly and manufacturing process.

Impedance Stability

Impedance is the measure of the current opposition when applying voltage. In many design applications, the stable impedance is essential and is an area where the materials like Rogers and FR-4 are applied.

FR-4, despite its low cost, is prone to high variations in the dielectric constant with the change in temperature across the length and width of the substrate. In terms of impedance stability, Rogers' material has a wider range of dielectric constants than FR-4 content.

High-frequency laminates are preferable for circuits that require little variation over wide temperature ranges. In this case, you may need to use printed circuit boards made of Rogers materials rather than FR-4 materials, especially if most of your operations involve working in high-temperature environments.

Dielectric Constant

The dielectric constant of any material measures a substance's ability to store some electrical energy across an electrical field. When it comes to dielectric constant, FR-4 has a dielectric constant of about 4.5, which is much lower than Roger's material, which has a dielectric constant of about 6.15 to 11.

The dielectric constant of FR-4 is comparatively higher than that of plastic materials. Using FR-4 materials can save at least 25% of PCB made from such materials. Other factors that make FR-4 articles available include their lightweight, moisture resistance, and high dielectric strength. Even though the Rogers PCB has a higher dielectric than FR-4, you can go with FR-4. FR-4 and Rogers 4350b and 4350 are similar manufacturing processes, although FR-4 stores electrical energy effectively.

Thus, PCB with higher dialect trends breaks easier when subjected to intense electric fields.
