Detailed Explanation

Wave soldering pallets (also called carriers or fixtures) protect certain areas of a PCB from molten solder during selective or wave soldering processes. Over repeated cycles, these pallets accumulate flux residues, solder splashes, and oxide buildup. If not cleaned regularly, these contaminants can: transfer onto PCBs causing solder defects, alter the thermal characteristics of the pallet leading to inconsistent soldering, create bridges and solder balls on protected areas, and damage the pallet material reducing its lifespan. Wave pallet cleaning machines use specialized cleaning chemistries and mechanical action (brushing, spraying, or ultrasonic) to remove these deposits without damaging the pallet material — typically high-temperature titanium or aluminum. Samtronik's pallet cleaning machines feature adjustable spray pressure and temperature-controlled cleaning baths suitable for all common pallet materials.
