What is the 01005 process? Why is 01005 process expensive in PCBA processing?
It is mainly because the thin welding paste is more likely to form a larger cavity, or the thickness gap of the weld is too small, leading to the volatiles of the welding machine more difficult to discharge through this "channel", so that the pr...
PCBA processing reflow welding and wave welding difference
In the through-hole PCBA assembly technique, the component is inserted into the drilled hole and a strong solder joint is formed by wave soldering. Usually, through - hole components are inserted manually
Causes of virtual welding in PCBA processing
The reasons for the appearance of virtual welding in PCBA processing are as follows: 1. Oxidation of pad and component pins; 2. Less tin; 3. The temperature is too high or too low, 4 welding paste melting point is low, 5, solder paste quality problems
