If PCB is bent before we use smt pick and place machine ？

After the SMT pick and place chip machine processing ,many factories will encounter the phenomenon of bending and rocking of the circuit board during reflow soldering. In severe cases, it may cause bad SMT phenomena such as empty welding of electronic components and tombstones. These phenomena are caused by Because of what? It is because of the uneven pressure on the board or the uneven pressure on the board, which leads to the phenomenon of bending or rocking. When the board passes through the high temperature of reflow soldering, the circuit board will become soft, and the thermal expansion and contraction of the circuit board material. The characteristics of chemical factors have resulted in bent plates and rocker plates.

Why use lead-free soldering for SMT chip processing

Why use lead-free soldering for SMT chip processing
When customers inquire about SMT chip processing, they often ask whether you are using lead-free soldering or leaded soldering. We will tell customers that both lead-free and leaded soldering are available, and the prices are different. What is the difference between leaded soldering and why should lead-free soldering be used for SMT chip processing? We will introduce the difference between leaded and lead-free soldering.
