²úÆ·²ÎÊý£º
wave solder pallet materials are designed and typically recommended for use in manufacturing solders pallets for wave-solder applications of printed circuit boards (PCB's). These materials can also be used for carriers in solder paste printing, SMT placement, IR-reflow, and conformal coating operations.
