Automatic welding and conveying equipment for circuit board

Technical Field

Background

Wave soldering is a batch soldering process that can produce numerous circuit boards in an extremely short amount of time. It works by passing each circuit board over a molten solder pad, with the pump in the pot creating a "wave" of solder that flushes over the board, soldering the components to the board.

Temperature control is important in wave soldering processes, and if the temperature is not adequately controlled, mechanical stresses can develop on the circuit board, resulting in cracking and loss of conductivity. Insufficient preheating can create voids that can affect the strength and conductivity of the circuit board. The wrong soldering temperature may result in that a proper solder thickness cannot be obtained, which makes the board more susceptible to pressure.
