How to solve the problem of two or more solder joints are connected by tin in SMT
May 07 , 2021
Product quality has become the lifeblood of business survival. In the SMT assembly line, after the PCB passes through the placement machine, it is about to face the heating and soldering forming of reflow soldering. Generally, after reflow soldering, AOI testing is required. If the IC is not well controlled, there will usually be undesirable conditions such as two or more solder joints are co...

What is rigid flexible PCB
Jun 07 , 2021
Rigid flexible printed circuit board is a hybrid circuit board design that integrates elements of hard PCB and flexible PCB circuits. Rigid flexible printed circuit boards are rigid at certain points on the circuit board and flexible at other points. Therefore, the flexible part of the PCB circuit can be folded or continuously bent, but the shape of the area for additional support needs to be...
