Description
Function
Through the high-speed moving precision welding head, non-contact local welding is performed on the specified solder joints/areas of the circuit board, replacing the whole board welding, which is suitable for the rapid welding and rework of large-scale, high-precision electronic components.
Advantages
High efficiency and high speed:
fast welding speed, support for mass production, and greatly improve production capacity.
Precise and controllable:
high positioning accuracy, can set personalized welding parameters (temperature, time, solder amount), reduce the risk of thermal damage.
Flexible and economical:
offline operation does not occupy the production line, adapts to multiple varieties of changeover, saves solder and labor costs.
Yield improvement:
local welding avoids the influence of high temperature on the whole board, improves the reliability of solder joints and product yield.
