Abstract
An adapter to connect device leads to contacts arranged in a rectangle on a circuit surface. The adapter has a body and leads that extend outwardly, downwardly and then outwardly again in a pair of opposing curves to form feet which match the pattern on the circuit surface. The body has sites for connecting with the device and supports conductive elements connecting the leads to the sites. The adapter may connect gullwing-shaped device leads disposed in a rectangle (e.g., QFP) to contacts in a similar pattern. A substrate, such as a printed circuit board, may support the conductive elements. The conductive elements and adapter leads may be portions of a lead frame with portions of the body molded around them. A connector may provide connections between attachment sites and device leads. This connector may be a separate body, may include socket terminals, and may mate with another connector which has conductive elements for making connections between it and attachment sites on a second body, which may be contact pads for making solder connections to the leads of the device. Strain relief elements are shown. The body may include a stack of connected body portions. The device leads ma…
