Abstract
Abstract Two rows of terminal pins projecting from an adapter plug are soldered simultaneously to a like number of solder coated strips on both faces of a printed circuit board. Clamping and carriage assemblies fixedly position one row of terminal pins opposite the strips on a respective face of the board. Heater blades are positioned opposite each face, bring the pins and strips together and melt the solder. Forming blades positioned opposite each row of pins stress the pins against the strip while the solder is still molten, simultaneously registering each pin with its respective strip.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
137 words
In an apparatus for simultaneously bonding surfaces of two rows of spaced terminal pins projecting from an adapter plug to surfaces of rows of a like number of spaced strips on both faces of a dielectric card inserted therebetween, the surfaces of an associated pin and strip forming a set, at least one surface of each set being coated with a low melting point material, the improvement comprising: a pair of heater blades, one positioned opposite each face of the card for bringing the surfaces of the pins and strips together and melting the low melting point material; and a pair of forming blades, one positioned opposite each row of pins for engaging the pins and stressing the surfaces of the pins against the surfaces of the strips while the low melting point material is still soft.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
28 words
The improvement according to claim 1 in which the forming blades are provided with grooves for receiving the pins and for registering the pins with their respective strips.
Claim 4
Dependent Claim
67 words
The improvement according to claim 1 including a clamping assembly for holding the board fixedly in a vertical plane and for providing access to the strips on both faces of the board; and an adapter plug carriage assembly for positioning the adapter plug fixedly with respect to the board and for positioning one row of terminal pins opposite the strips on a respective face of the board.
