DIP Offline Selective Soldering Machine achieves a breakthrough in core technology through precise localised soldering techniques in electronic manufacturing. Its primary applications are as follows: Resolving soldering challenges in high-density mixed-assembly boards Avoiding thermal damage to surface-mount components Traditional wave soldering requires the entire board to be immersed in tin, and high temperatures can cause surrounding surface-mount components (such as BGA chips) to remelt. Selective wave soldering uses a CNC nozzle (with a precision of 0.1mm) to spray dynamic tin waves only onto the pins of through-hole components, protecting the structural integrity of sensitive components. Eliminating micro-pitch bridging defects By independently adjusting parameters for each solder joint (temperature/time/solder volume), single-point soldering is achieved for pins with 0.5mm spacing, reducing bridging rates to below 0.03%, far below the industry average of 5% for traditional wave soldering.
