Chip carrier soldering pallet

摘要

A pallet for conveying a plurality of ceramic leadless chip carriers (LCC) through an automated wave soldering machine. The pallet includes recesses formed to receive and contain the LDD's with the lid of the LCC facing into the recess. This results in protecting the lids from the molten solder. Additionally, the recesses are formed in a diamond orientation with a solderable pin placed at the trailing apex of each recess. Both the pin and the diamond orientation prevents solder build up on the trailing conductive pads, resulting in enhancing the coplanarity of the solder on the pads.
