What are the main applications of PCB boards

PCB, also known as printed circuit board, is the provider of electrical connections for electronic components and the core component of electronic equipment. So, what are the main

What are the lamination methods of PCB multilayer circuit boards?

PCB circuit boards are classified according to the number of circuit layers: they can be divided into single-sided, double-sided and multi-layer boards. Common multi-layer boards a

Reasons and Solutions for PCB Nickel Electroplating Process Failures

In PCB proofing, nickel is used as a substrate coating for precious and base metals. For some surfaces with heavy load wear, the use of nickel as a backing layer of gold can greatl

Detailed explanation of rigid-flex board and IC carrier board

What is a rigid-flex board? Rigid-flex board refers to the combination of a soft board and a hard board. It is a circuit board formed by combining a thin-layer flexible bottom laye

4 steps of PCB inner layer processing

For multi-layer printed circuit boards, the working layer of the inner layer is sandwiched in the middle of the entire board, so the multi-layer printed circuit board should first

How much do you know about the surface plating knowledge of FPC flexible circ...

Electroplating is a process in which metal or alloy is deposited on the surface of a workpiece by using the principle of electrolysis to form a uniform, dense and well-bonded metal

Near-hole problems that must be paid attention to in multi-layer PCB circuit ...

Multi-layer PCB circuit board companies often encounter the problem of "the hole is too close to the line, which exceeds the process capability". When we design the PCB b

Back Drilling Technology in PCB Production

Friends who have done PCB design know that the design of PCB vias is actually very particular. Today, I will explain in detail the back-drilling technology in the production of PCB

What are the common problems of manual soldering wire for PCB aluminum substrate

In the production process of PCB aluminum substrate, in order to ensure its better application effect, manual soldering of tin wire is usually used afterwards. This has certain req
