Function<\/mark><\/strong>
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.<\/p>\n\n\n\n

Advantages<\/mark><\/p>\n\n\n\n

High efficiency and high speed:<\/strong><\/p>\n\n\n\n

fast welding speed, support for mass production, and greatly improve production capacity.<\/p>\n\n\n\n


Precise and controllable: <\/strong><\/p>\n\n\n\n

high positioning accuracy, can set personalized welding parameters (temperature, time, solder amount), reduce the risk of thermal damage.<\/p>\n\n\n\n


Flexible and economical: <\/strong><\/p>\n\n\n\n

offline operation does not occupy the production line, adapts to multiple varieties of changeover, saves solder and labor costs.<\/p>\n\n\n\n


Yield improvement: <\/strong><\/p>\n\n\n\n

local welding avoids the influence of high temperature on the whole board, improves the reliability of solder joints and product yield.<\/p>\n\n\n
