The WQB 4000SOPS was specially developed for use in repair and laboratory facilities. It is ideal for repairing circuit boards, including replacing BGA and FINEPITCH components. It can also be used for producing circuit boards as part of laboratory work.
The device has effective preheating of the circuit board from below and targeted heating of the components to be repaired from above up to the reflow temperature in conjunction with reliable process control. The 2-zone infrared bottom heater ensures rapid heating and homogeneous substrate temperatures, while the hot gas top heater with digital control electronics for temperature monitoring and air volume regulation enables finely dosed heat energy to be supplied to the components. A temperature sensor in the hot gas nozzle ensures efficient control of the top heating and offers the highest level of process reliability.
The split optics positioning system with a digital 2 megapixel camera and 2 colored LED lights enables precise placement of the components. The x, y, teta precision adjustment of the positioning unit and the so-called picture-in-picture process enable congruent alignment.
