The Reflow Soldering Oven with LCD Display

Description:
One of SMD soldering techniques is using a reflow soldering oven. Reflow soldering technique is used when it is impossible to solder components by hand. These may include ball grid arrays (BGA), small pitch quad flat packs. Or simply solder any SMD element to make board look professional and smooth.
Soldering oven controller is based on […]
