Abstract
Abstract A tool for accurately positioning a flat pack multi-lead component to a PCB during soldering of the leads. The tool has a double function in providing both an accurate location for the board and the component while re-flow soldering takes place. It also provides fool-proof orientation of the component. The basis of the tool is four locating pins which locate at the corners of a square flat pack component but each pin is accurately made and positioned to locate the end leads of the two adjacent sides with a small clearance from the moulded body itself. This takes account of variations in the moulded bodies. One corner of the square body is chamfered and one of the pins is similarly shaped to ensure correct orientation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
A jig for locating a flat pack multi-lead component having a multi-edged body with leads extending perpendicularly from at least two of the edges on a mounting surface having mating electrical conductors comprising a base member with a plurality of shaped locating pins projecting perpendicularly from said base member, said locating pins being adapted to pass through orifices formed in the mounting surface so that said mounting surface is located in a predetermined position on said base member, said locating pins being positioned so that the intersection of said at least two edges of the body having the extending leads abut a mutually shaped portion of at least one locating pin when said component is placed on said mounting surface whereby said locating pins position said component by contacting the end leads only of the leads extending from said at least two edges to connectors on said mounting surface.
Claim 2
Dependent Claim
149 words
A jig for locating a flat pack multi-lead component having a multi-edged body with leads extending perpendicularly from at least two of the edges on a mounting surface having mating electrical conductors comprising a base member with a plurality of shaped locating pins projecting perpendicularly from said base member, said locating pins being adapted to pass through orifices formed in the mounting surface so that said mounting surface is located in a predetermined position on said base member, said locating pins being positioned so that the intersection of said at least two edges of the body having the extending leads abut a mutually shaped portion of at least one locating pin when said component is placed on said mounting surface whereby said locating pins position said component by contacting the end leads only of the leads extending from said at least two edges to connectors on said mounting surface.
Claim 3
Dependent Claim
27 words
