Our technicians use the latest technology in CNC machining to fabricate wave solder pallets. Fabrication mainly consists of removing material from areas of the pallet where the circuit board is to be exposed to the wave, and solder is required.
Every wave solder pallet is custom designed to fit a specific PCB layout and meet unique process requirements however, they usually have the following components:
A) Base plate: Also known as base pallet serves as the foundation for the pallet and provides a flat surface for the PCB to rest on during soldering. It typically features cutouts and openings that allow the solder to flow through and create the necessary solder joints, while protecting the components from being damaged.
B) Top hat: Also known as Cover Plate, is designed to hold the components in place during wave soldering and sits on top of the Base Plate. It typically features openings to reduce weight.
C) Alignment dowels: They are used to ensure the Top Hat is correctly positioned above the PCBs.
D) Hold downs: They hold the PCB securely in place. They are commonly made of titanium and plastic instead of steel to avoid cross contamination.
E) Stiffener Bars - They are used to provide support to the pallet to reduce twisting and bending. They also prevent solder from going over the top area of the pallet.
F) Gas relief: Also known as vent holes are indentations on the pallet to allow gases to escape during soldering. They also help to prevent defects such as solder voids or insufficient wetting, which can occur when gases become trapped in the solder joint.
