An extractor tool for removing a circuit module from a connector where the module has a substantial length, has a plurality of electrical contacts resiliently engaged with corresponding connector contacts, and has latch means at opposite ends receiving engagement by separate connector latches for detachably retaining the module on the connector. The tool has a thin flat body with spaced parallel legs extending from one side of the body to accommodate the substantial module length between the legs and has tapered surfaces on the edges of the distal ends of the legs to be pressed against the separate connector latches to release both of the latches at the same time to permit removal of the module from the connector free of damage to the latches or the resiliently engaged contacts.

Extractor tool

A circuit board system resiliently mounts a plurality of daughter boards with high circuit interconnection density on a mother board using pairs of mating connectors having welded contact members accommodated in novel arrangements in the respective connectors to permit high density of electrical interconnection with convenience and reliability. Contact parts of substantial size are welded into contacts in one connector to detachably interconnect with contact parts of similar size in mating connector to improve interconnection releability. Novel contact arrangements permit accommodation of those parts of substantial size in the mating connectors. Sheet metal spring or post parts welded into the contacts in both connectors permit the contacts to be conveniently loaded into connector bodies and permit large numbers of contact springs or posts to be soldered to terminal pads or circuit paths on mother or daughter boards with high density. Temporary fixtures mount on connectors to facilitate precise soldering of leaf springs to very closely spaced terminal pads on daughter boards; resilient mounting of the mother board facilitate daughter board engagement with heat sinks; and organizer plates fit on extending ends of connector contact posts to facilitate their insertion into mother board mounting holes with high interconnection density.
