Chip carrier socket

A chip carrier socket comprising an insulating housing molded in one piece of plastic material and including a rectangular frame-like body portion surrounding a centrally located chip carrier support, the frame-like body portion having sides formed with respective rows of contact receiving cavities;

• contacts each comprising a contact portion and a solder tab portion and being anchored in respective cavities with rows of the contact portions extending inwardly of the frame-like body portion for establishing electrical connection to respective leads of rows of leads on respective sides of a rectangular chip carrier received in the chip carrier receiving recess and with soldering tabs of the contacts extending inwardly of the frame-like body portion and located closely adjacent in rows at a circuit board engaging face for soldered connection to respective soldering pads of the circuit board by reflow soldering;
• bridge portions extending from locations of the frame-like body portion adjacent respective corners thereof, and between respective adjacent ends of adjacent rows of soldering tbs, to respective adjacent locations of the chip carrier support, locating the chip carrier support with respective perimetrical edges thereof spaced apart from the respective adjacent sides of the frame body and defining therewith apertures aligned over the solder tabs, one aperture per row, so that the field of view of each row of soldering tabs through a corresponding apertures unobstructed whereby all soldering tbs in a row and spaces between adjacent soldering tabs of the row can be seen through the aperture aligned thereover.

A chip carrier socket comprising:

• an insulating housing molded in one piece of plastic material and including a rectangular, frame-like body portion surrounding a centrally located chip carrier support, providing a chip carrier receiving recess defined by the profile of the frame-like body above the support;
• contacts each comprising a contact portion and a solder tab portion and being anchored in respective sides of the body portion with rows of the contact portions extending inwardly of the portion for establishing electrical connection to respective leads of rows of leads on to respective sides of a rectangular chip carrier received in the chip carrier receiving recess and with soldering tabs of the contacts extending inwardly of the body portion and located closely adjacent in rows at a circuit board mounting face or soldered connection to respective soldering pads of the circuit board by reflow soldering;
• bridge portions extending rom locations of the body portion adjacent respective corners thereof, and between respective adjacent ends of adjacent rows of soldering tabs, respective adjacent locations of the chip carrier support, locating the chip carrier support with respective perimetrical edges thereof spaced apart from the respective adjacent sides of the body portion and defining therewith apertures aligned over the solder tabs, one aperture per row, so that the field of view of each row of soldering tbs through a corresponding aperture is unobstructed whereby all soldering tabs in a row and spaces between adjacent soldering tabs of the row can be seen through the aperture aligned thereover.
