Flux-cored arc welding. Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant-voltage or, less commonly, a constant-current welding power supply.
Flux finds an across the board application in ball framework clusters (BGAs) and a few other gear, for example, flip chip and surface mounted gadgets (SMD). BGAs have been the key shoppers of weld flux and are probably going to remain so over the approaching years. In 2015, a share of over 63% in the general interest for bind flux was held by BGAs.
