The invention discloses a method for manufacturing a printed circuit board edge connector, relates to the field of manufacturing process for a printed circuit board, and can solve the residue problemsof an edge connector plating lead of the printed circuit board. The method for manufacturing the printed circuit board edge connector comprises the following steps: forming the edge connector platinglead and an edge connector area on the printed circuit board once, wherein the width of adjacent parts of the edge connector plating lead and the edge connector area is equal to the width of the edgeconnector area; coating a covering substance to form an edge connector plating reserved area, and plating the edge connector plating reserved area to form the edge connector; and removing the covering substance, and etching the edge connector to obtain the edge connector without the plating lead. The method is suitable for manufacturing the edge connector without the lead for the printed circuitboard.

With the present invention, a reflow soldering method is provided for soldering a nonvertically approaching lead, which is part of a nonvertically approaching device (e.g, an edge connector), to a corresponding soldering surface (e.g., a pad on a circuit card) that includes solder. The soldering surface and solder are heated in an oven to melt the solder. While the solder is liquids, the nonvertically approaching lead is mated with the soldering surface as it is inserted into the solder. The soldering surface, solder, and nonvertically approaching lead are then cooled, and the solder solidifies to conductively mount the nonvertically approaching lead to the soldering surface.

An improved memory module and method of manufacture are presented. The memory module takes on the same outer dimensions as conventional memory cards. The memory module includes an integrated circuit and a conductor encased within molded resin. The conductor can be taken from a tape or a lead frame, and can include bumps or wires extending from the conductor to corresponding bonding pads on the integrated circuit. The bonded integrated circuit can thereafter be placed within a cavity formed inside a mold housing, where resin may be injected to form the memory module. The conductor can also be shaped so as to extend on multiple planes from the connection point on or near the bonding pad to an edge connector residing near one edge only of the memory module. The conductor is thereby connected to the integrated circuit and provides slide-in, releasable coupling to a receptor.

A memory module substrate printed-circuit board (PCB) has multi-type footprints and an edge connector for mating with a memory module socket on a motherboard. Two or more kinds of dynamic-random-access memory (DRAM) chips with different data I/O widths can be soldered to solder pads around the multi-type footprints. When ×4 DRAM chips with 4 data I/O pins are soldered over the multi-type footprints, the memory module has a rank-select signal that drives chip-select inputs to all DRAM chips. When ×8 DRAM chips with 8 data I/O pins are soldered over the multi-type footprints, the memory module has two rank-select signals. One rank-select drives chip-select inputs to front-side DRAM chips while the second rank-select drives chip-select inputs to back-side DRAM chips. Wiring traces on the PCB cross-over data nibbles between the solder pads and the connector to allow two ×4 chips to drive a byte driven by only one ×8 chip.
