Fully automated in-line selective soldering machine using the proven ‘traveling mini–solder wave”. It is used to install through hole components on double sided SMT boards within close proximity of adjacent components. This system overcomes the limitations of operator dependent soldering with a truly flexible molten solder delivery system. KISS-104 couples high throughput with precise process controls. The programmable features provide the tools to set all process parameters, including flux application, solder immersion depths, pre-heat dwells, travel distances and speeds, solder temperature and wave height. Once set, the system will repeat precisely.
