Our repair rate remains above 90%. However, circuit boards with the following conditions are considered irreparable or temporarily irreparable: chip programs are damaged and our company currently has no replicable programs or spare parts; It is very difficult to procure components that are particula...
Paper based circuit boards are divided into flame retardant and non flame retardant according to their flame retardant properties. The advantage is low cost, the disadvantage is poor adhesion between copper and substrate, but both are sufficient for welding under normal conditions. The problem of co...
With the transformation of surface soldering to lead-free type, the soldering temperature that the circuit board needs to withstand becomes extremely high, and the requirements for the thermal shock resistance of the surface solder mask layer are increasing. The requirements for the terminal surface...
The selection of PCB boards must strike a balance between meeting design requirements, scalability, and cost. The design requirements include two parts: electrical and mechanical. This material issue is usually more important when designing very high-speed PCB boards (frequencies greater than GHz)....
