The thickness and copper thickness are mainly considered in the fabrication and blanking of circuit boards. For boards with a thickness greater than 0.8MM, the standard series is 1.0 1.2 1.6 2.0 3.2 MM. If the thickness is less than 0.8MM, it is not a standard series. The thickness can be determined according to needs,……

1. The process characteristics of selective welding can be understood by comparing with wave soldering. The obvious difference between the two is that the lower part of the circuit board in wave soldering is completely immersed in the liquid solder, while in selective soldering, only some specific areas are in contact ……

The prerequisite for circuit problem calculation is to correctly identify the circuit and understand the connection relationship between various parts. For more complex circuits, the original circuit should be simplified into an equivalent circuit for easy analysis and calculation. There are many ways to identify circu……

Hardware engineer just contactedMultilayer PCBIt's easy to get dizzy. The lines are like spider webs. Today, I found several internal structure drawings of multilayer PCB circuit board, and used stereo graphics to show the internal structure of PCB drawings of various stack structures.

1. Customers often design that there is no window on both sides of the VIA hole with green oil, or there is a headache on the circuit board. Or open the window on one side. What should I do with this design?

The so-called fpc refers to the abbreviation of flexible printed circuit. In life, we also call it flexible circuit board, flexible circuit board and flexible printed circuit board, so we call it fpc or soft board for short. Maybe we all know some characteristics of fpc in this industry, such as fpc wiring board with l……
