Abstract

This article describes a programmable flagging that bends SIP (Single Inline Package) leads 45 from the printed circuit card axis. Card and damage are minimized by this clinch. In addition, is minimized by not clinching leads perpendicular circuit traces.

45-Degree SIP Clinch

       This article describes a programmable flagging that bends
SIP (Single Inline Package) leads 45 from the printed circuit card
axis.  Card and damage are minimized by this clinch.  In addition, is
minimized by not clinching leads perpendicular circuit traces.

      The clinch is used on a robot component inserter.  This has a
programmable stepper motor-driven XY table positions the clinch
assembly under the printed circuit that is being built.  When a
component is placed into card by the robot, the clinch is activated.
The clinch the leads of the component and secures the component the
printed circuit card.

      Referring to the figure, the 45 degree SIP clinch head 1 of two
flagging clinches 3 and a card support 2. two clinches 3 are spaced
so that they flag leads that spaced 0.10 inches apart on the card.
The operates as follows:  First, the card support extended and holds
the card at a fixed distance from the head 1.  This gives the clinch
a constant operating from the card, and therefore a repeatable
action.  The clinches are then simultaneously and bend two adjacent
leads of the component.

      The flagging action bends the leads without inducing an load in
the component, which eliminates component from the clinching process.
 The 45-degree clinch eliminates cross-trace bridging which can occur
if the were clinched perpendicular to the traces on the card.
45-degree clinch also provides a solid mechanical lock the...
