FR4 PCB

FR4 is the most important material in the PCB assembly. Electric engineers and technicians normally design PCB boards with the FR4 PCB. There is a big demand for FR4. FR4 printed circuit board is normal and easy to design. The FR4 PCBs are popular as they are cost effective and can be widely used.



High-TG PCB

Normally FR4 Tg is 130-140°, moderate Tg is over 150-160 °, High-Tg is greater than 170°.The higher of Tg, the better performance of PCB moisture resistance, heat resistance, chemical resistance, stability and other characteristics.

What is PCB?

PCB is the abbreviation of the printed circuit board. PCB composed by insulated baseboard, pads for electronic components and copper foil connecting wires. PCB can replace complex wiring to achieve circuit connection between components in the circuit.

PCB is the motherboard of electronic components. Before the advent of PCB, the interconnection between electronic components was done directly by wires.  Today, PCB has been widely used in the electronics industry, due to the  PCB tecnology, manual wiring errors can be avoided, and electronic components can be automatically DIP or SMT, automatic soldering, and automatic detection, ensuring the quality of electronic device and improving labor productivity, reduce costs as well.

What Is the Difference Between PCB And PCBA?

PCB is a blank circuit board without any electronic components soldered on. It just composed by baseboard with pads and copper foil connection wires.

PCBA is a complete assembled board with electronic components. We apply surface mount technology and through-hole soldering technology solder the components onto the board. The components are soldered to the board can be SMD, through hole, UBGA, QFN, POP, leadless chips, connectors and terminals.

Printed circuit boards (PCB) are of two sorts relying on their substrates - inflexible printed circuit boards and flexible printed circuit boards. PCBWin devotes to conform essentially the most serious quality normal in PCB fabrication and PCB assembly. Receive your PCBs in time as agreed. Normal PCB Provide: $20,5PCBs, FR4(RoHS),2 layer,four×four inch, Lead Free HASL; 6 day lead time. Entech Electronics China is a full service PCB (printed circuit board) provider and offers low volume, fast turn samples right via to medium and high quantity manufacturing batches.

The quickest is , which is able to get your boards shipped subsequent day, with solder masks, 3oz full copper capabilities and so on. PCBWin additionally makes efforts to low the fee frequently so we might present low price to our prospects. There are companies that specialize in Electronic Design Companies, or EDS.

We will have multilayered PCBs manufactured by way of techniques such as PCB milling, copper etching, screen printing and so on. This software program is kind of useful for RF PCB design and for PCBs delivering blended signals. The manufacturing time is the manufacture time, it doesn't embody the checking time, packing time and transport time.

While some individuals recommend that corporations will lower their total IT costs and subsequently hold again on outsourcing, research show that very few firms will truly cut back their budgets. Many mobile phone keypads are designed with plastic keys over rubber.

Remaining stage is production, which is self-explanatory. Most PCB fabrication firms also offer prototyping companies - this includes creating a working PCB model earlier than actual mass production can commence. The subsequent stage of the design course of was to convert the circuit diagrams to a board structure that could be transferred to copper clad fibreglass circuit board.

Metal core PCB

With the increase of the LED chip size and polycrystalline LED the development of packaging design, LED the heat load are also redouble,in addition to this the heat dissipation capacity of plate material, its thermal stability of materials are also affect the LED products’ life.In short, high power LED products loading board material needs to have at the same time the characteristics of high heat dissipation and high heat resistance, so the packaging substrate material becomes the key factor, on the application of traditional LED heat dissipation substrate,Metal Core PCB be widely used.

Metal core printed circuit board PCB (you aslo can call it MCPCB,Thermal PCB,Heavy Copper PCB) is kind of PCB board with metal base material instead of woven glass FR4, FR3 or others.There is single sided, double sided, and multilayer board. The most of Metal Core PCB manufacturers are commonly used metal core material is aluminum, copper and alloy. Aluminum is the most frequently used among them due to its good heat transfer ability,dissipation ability and relatively cheaper costs than copper,even which may has a better performance,so it widely was accepted.copper although have better performance,but its cost more expensive,steel is more rigid than both aluminum and copper,it has normal steel and stainless steel,but its thermal conductivity is lower than others,simple speaking,aluminum material is the best choice,even considering from cost,rigidness and thermal conductivity.

There are single sided,two layer and multi-layer mcpcb,the Single sided metal core printed circuit board consists of a metal base (aluminum or copper alloy), dielectric layer, and copper conductor layer. The single layer MCPCB can be used with surface mount and chip & wire components. It provides much lower thermal resistance than FR4 PCB. And the metal core provides lower cost and allows much larger areas than ceramic substrates.

Metal Core PCB is used to replace traditional FR4 or CEM3 PCBs because of the ability to efficiently dissipate heat away from the components. This is achieved by using a thermally conductive dielectric layer.

The prepreg dielectric provides excellent heat transfer from the foil and components to the base plate, while maintaining excellent electrical isolation. The base aluminum or copper plate gives the single-sided substrate mechanical integrity, and distributes and transfers the heat to a heat sink, mounting surface or directly to the ambient air.
