Copy board to change the board industry said that the car is growing in popularity, automotive sensor market demand will continue to maintain a growing trend.
The characteristics of flexible circuit board patch: 1, flexible circuit board patch after all lines configuration, less than other circuit board assembly, 2, flexible circuit board itself small size is more convenient to carry, 3, light weight, flexible
The interconnection of various plates in electronic facilities often requires the use of PCB plug sockets with spring contacts and a matching preset printed circuit board with connected contacts.
The temperature range can be automatically selected. It has its own refrigeration system, without external circulating water cooling device, and adopts stainless steel water pump, so that the noise is reduced and the generation of rust is eliminated, avoi
In the high frequency circuit, the noise of the power supply has an obvious influence on the high frequency signal. Therefore, the first requirement is that the power supply be low noise. Clean land is just as important here as clean power.
Ordinary Tg sheet is above 130 degrees, High-Tg is generally above 170 degrees, and medium Tg is above 150 degrees. The Tg of the substrate has been improved, covering heat resistance, moisture resistance, chemical resistance, stability and so on.
The working principle of the circuit board is to use the board based insulation material to isolate the outer copper foil conductive layer, so that the current flows along the preset route in various components.
which is equivalent to reviewing the schematic diagram, modifying the scheme for design, and si simulation at the same time. There are many types of power supply with small voltage and large current on the board.
enterprises have developed and designed epoxy resins with high speed and high frequency plug holes, expecting to show epoxy resins with stronger transmission for customers and help customers improve the competitiveness of products
Flexible PCBS (FPCS) are increasingly needed, and PCB manufacturers are accelerating the development of thinner, lighter and more dense FPCS.
it is best to check whether the power supply of the equipment is correctly supplied to the circuit board as required, and whether the interface plug-ins on the circuit board are connected.
As long as the circuit board has detected the problem, then maintenance is easy. The following is a summary of the circuit board maintenance basic formula, convenient and practical.
