Process Overview
The operator places the PCB onto the location rails and starts the automated cycle. The “Automated Fiducial Correction”identifies the stat point. The cycle begins by applying flux to all the programmed sites. Next the mini solder wave is auto-matically moved under the component to be soldered. The solder nozzle raises to “wet” the first pins. The solder wave travels the length of the component soldering the through hole leads to the PCB. At the completion of the travel the sol-der pot lowers and moves to the next site. All programmed sites are soldered in the same cycle. An automated stepping function allows solder arrays of boards in an X-Y matrix. After completing the cycle the pot can be programmed to return to the start position ready for the next cycle.
