Q:Circuit board A what it means: Circuit boards are: circuit boards, PCB boards, aluminum boards, high frequency boards, thick copper plates, resistors, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etched technology) circuit boards, etc. So that the circuit mini, visualization, for the fixed circuit of mass production and optimization of electrical appliances play an important role.

Q:How to eliminate the protection of IC on the circuit board paint: Circuit board: Printed Circuit Board (PCB), also known as circuit boards, PCB board, aluminum plate, high frequency board, ultra-thin circuit boards, ultra-thin circuit boards, printing (copper etching technology) circuit boards.

Q:PCB circuit board? What is it?: Because it is made using electronic printing, it is called "printed" circuit board. PCB is divided into single-sided circuit boards, double-sided circuit boards, multi-layer circuit boards, flexible circuit boards, aluminum-based circuit boards, with the rapid development of science and technology, more and more demanding, but now or single- the Lord.

Q:Protel how to lock all components: In the electronics industry CAD software, it deservedly ranked in front of many EDA software, is the preferred software for electronic designers, it began to use in the country earlier, the highest penetration rate in the country, and some colleges and universities of electronic professional also Special courses to learn it, almost all of the electronics companies have to use it, many large companies in the recruitment of electronic design talent in their conditions on the bar often asked to use PROTEL. Early PROTEL mainly used as a printed circuit board automatic routing tools,

Q:Which boards are difficult boards?: Process capacity; generally HDI, rigid-flex; ordinary factory to do 2/2 line yield is not ye to the

Q:Circuit board how to easily cut off the line: The multilayer board refers to a printed board having three or more conductive pattern layers interposed therebetween and interposed therebetween so that the conductive patterns are interconnected as required. Multi-layer circuit board is the electronic information technology to high-speed, multi-functional, large capacity, small size, thin, lightweight direction of the product.

Q:Just start learning computer hardware maintenance technology, only know the melting point of tin is 230 degrees Celsius, if the PCB board unloading capacitor resistors and other components, then the hot air gun should be transferred to a few degrees Celsius will not damage the PCB board?: Its development has been 100 years of history; its design is mainly layout design; the main advantage of using the circuit board is to greatly reduce the wiring and assembly errors, improve the level of automation and production labor rate.

Q:Circuit board how to see the line: Above is an example of ordinary CRT TV, but now the LCD LCD / PDP plasma TV most of the line principle and ordinary CRT TV is different, which requires you to see some of this book. Player, line principle and the above products are completely different, if you want to understand MP3, you have to see some of this book.

Q:What is the classification of circuit boards: The first is a single panel, on the most basic PCB, the parts are concentrated on one side, the wires are concentrated on the other side. Because the wire only appears in one side, so called the PCB is called single-sided circuit board. Single-sided panels are usually made simple, low cost, but the drawback is that it can not be applied to too complex products.

Q:PCB printed circuit board, the "printed" is not referring to thermal transfer? Mass production PCB is also produced by thermal transfer method?: Now the industry batch processing of PCB are used to process the etching method: the substrate itself is composed of resin and adhesive in the resin on the copper layer, commonly known as the core, and then through the film, the way the formation of the core plate Curing the protective film, will need to form part of the line protection,
