Abstract
A Leadless Chip Carrier (LCC) is mounted on a circuit board on elongated solder posts to provide clearance between the LCC and the board. The process for producing solder posts involves the deposition of a temporary stencil surrounding the conductive pads on the board. The removable stencil around the pads provides support for molten solder during reflow and prevents the chip carrier from compressing the molten solder thereby insuring desirable spacing between the chip carrier and the board.
