What is the solder wire in the PCBA assembly hand soldering
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
PCBA circuit board assembly hand soldering is a common processing technology in PCBA processing. Pate Technology has also introduced what PCBA circuit board assembly hand soldering is. Now, Bai Qiancheng will introduce what is the solder wire in PCBA circuit board assembly hand soldering. ?

The solder wire in the PCBA circuit board assembly hand soldering is an alloy composed of various tin-lead weight ratios, and the solid flux core in the sandwich is added, and the drawn metal wire-shaped solder can be used Welding and filling are called Solder Joints with mechanical strength.

Pay attention to whether the flux is corrosive, and whether the insulation resistance of the residue after soldering (Insulation Resistance, which is an incorrect statement by ordinary people) is high enough to avoid poor electrical insulation of subsequent PCBA assembly boards. The problem. Even in the future, "No Clean" flux will be required. The evaluation method can be selected from the "Moisture and Insulation Resistance" section 2.6.3 of IPC-TM-650. Sometimes when the effectiveness of the flux in the welding wire is found to be insufficient, additional liquid flux can also be added to help its effect, but be careful of the subsequent ion contamination of such liquid flux. iPCB is happy to be your business partner.
