The difference between the excimer laser and the impact carbon dioxide laser through-hole of the flexible circuit board:
Before designing a multi-layer PCB circuit board, the designer needs to first determine the circuit board structure used according to the scale of the circuit, the size of the circuit board and the requirements of electromagnetic compatibility (EMC)
At present, there are two general FPC welding processes, one is tin press welding, and the other is manual drag welding
Printed circuit board (PCB), also known as printed circuit board, is a provider of electrical connection of electronic components
Our common computer boards are basically epoxy resin glass cloth-based double-sided printed circuit boards, one of which is a plug-in component and the other side is a component foot welding surface. It can be seen that the solder joints are very regular. We call it the pad for the discrete soldering surface of the component feet
