.125" x .250"
Compliant pin technology** VARIPIN™
SERIES 6353
.025" Square Post
Discrete Press-Fit
Compliant section:
When the contact is
press-fit in, the section complies within the
hole. Stress is absorbed by the pin, not the
board, minimizing deformation of both the
hole and the plating.
**Licensed under U.S. patent RE 29513.

Assembly
The connectors shown here are easily
installed using simple tooling (available from
ELCO) and an arbor press. If desired, ELCO
will install these connectors into the mother-
board to provide a complete backpanel.
Important:
Building the hole accurately is
critical to proper press-fit joint perfor-
mance. The finished diameter of the hole is
a
reference
dimension. Tolerances for all
the factors in achieving that dimension
(drilled hole diameter, Cu plating thickness,
and solder plating thickness) must be
observed. Any deviation (e.g. a bigger hole
with thicker plating) may degrade the joint.
ELCO can provide engineering assistance
in specifying the “press-fit” holes.
