What Is a Pallet?

	In the electronic component assembly process, a “pallet” refers to a transport or masking fixture made of heat-resistant resin, as shown in the figure on the left. Pallets are referred to by various names, such as carrier pallets, solder pallets, dip pallets, and carrier pallets.
	This carrier pallet is used in the wave soldering process. In the wave soldering process, a carrier pallet is installed that covers areas where pre-mounted surface-mount components and other parts that must not come into contact with solder are located, while leaving openings only for the areas where through-hole components are to be soldered. The pallet is then passed over the raised pool of molten solder in the wave soldering tank to solder the components.
	The carrier pallet is designed to ・Protect pre-mounted components and their joints from the heat generated during the wave soldering process ・Efficiently apply solder to the components to be joined during the wave soldering process.

Cleaning the Carrier Pallet

In the wave soldering process, flux is first applied to the PCBs set on the carrier pallet using a spray or similar method. Soldering is then completed by passing the PCBs in contact over the molten solder bath.

At this point, flux may adhere to the edges of the carrier pallet’s openings. Depending on the type of flux, solder may creep up these edges, causing solder to adhere to masked areas. For this reason, the carrier pallet must be cleaned regularly.
