Methods to judge the quality of FPC circuit board: 1： Distinguish the quality of the circuit board from the appearance Generally, the appearance of FPC circuit board can be analyzed and judged from three aspects
At present, there are two general FPC welding processes, one is tin press welding, and the other is manual drag welding.
PCB proofing, as a component of high-precision electronic products, has been a very common existence in life. However, we all know that domestic professional PCB proofing design needs different point settings in different stages, and large grid points will be used for device layout in the layout stage. Let's take a look at the detailed PCB proofing layout setting skills.
According to the number of layers, single-sided, double-sided and multilayer circuit boards are divided according to the circuit layer inside.
Our common computer boards and cards are basically epoxy resin glass cloth based double-sided printed circuit boards. One side is the plug-in components, and the other side is the welding surface of the component feet. It can be seen that the welding points are very regular.
