Abstract

This connector establishes electrical and mechanical contact between the electrodes of a microminiaturized component, typically a chip semiconductor device and a substrate. The connector is inexpensive, easily handled and eliminates precision connections between the chip device and the supporting substrate.

Chip Connector

This connector establishes electrical and mechanical contact between the electrodes of a microminiaturized component, typically a chip semiconductor device and a substrate. The connector is inexpensive, easily handled and eliminates precision connections between the chip device and the supporting substrate.

In one form, shown in the upper and middle drawings, a strip of insulating material, typically TEFLON* or the like, is plated with copper or the like, as a conductive surface on the insulating material. Connector 20 is substantially V- shaped with the copper etched at the junction between the sides of the connector. The separation between the copper segments establishes two discrete conductive sections or electrodes. A solder coating is evaporated or otherwise deposited on the copper to provide the material for making a solder reflow joint to the chip device.

Substrate 22, shown in the lower drawing, has deposited on it conductive paths or electrodes descriptive of a particular electrical circuit. One conductive path, shown in an enlarged view for descriptive purposes only, includes opening 24 for connection to a nearby chip device, typically a transistor. The chip device has balltype electrodes 26, which appear on its top surface. The bottom surface of the device, coated with a flux, is loosely secured to a third electrode.

An interconnection is completed between electrodes 26 and the solder coated conductive paths by connector 20. After coatin...
