Method for a 164-position card edge connector for thicker width add-in cards

Disclosed is a method for a 164-position card edge connector for thicker width add-in cards. Benefits include improved functionality and improved ease of implementation.

Background

              A conventional 164-position card edge connector enables modules with a thickness of .062 inches (1.57 mm) across the pads to be plugged in. No flexibility is allowed in the design of higher end/higher capacity memory boards. No high-end card edge connector exists that enables  thicker add-in cards to be used.

Description

              The disclosed method is a 164-position card edge memory board connector for use on printed circuit boards (PCBs). The connector is mounted (soldered) on a board and interfaces with an add-in card (module) that is slotted into the contact opening. This enables signals to be connected between the memory board and the base board. The connector accepts add-in cards that are thicker than the standard .062-inch boards.

              To implement the disclosed method, the conventional tooling for the mold may be used as a reference. The required change in the plastic mold is in the width of the opening for attaching  the add-in card (see Figure 1). Keeping the center line constant, the width in the molding is increased to accept whatever PCB thickness is required, Additionally, the terminal die for the metal contacts are adjusted to accept the thicker board. The contacts are shifted apart in...
