Recommended ir reflow profile
WebbSURFACE MOUNT SOLDERING PROFILE Solder methods for surface mount are IR, vapor phase and solder wa ve. IR is the most used at th is time and discussion between users … WebbReflow soldering: Most surface mount components are reflow soldered. The two major types of reflow processes are: 1. infrared reflow - the most common type of reflow process. 2. vapor phase reflow - rapidly disappearing due to environmental restrictions on fluorocarbons. There are four process stages in soldering: 1. Preheat
