Terminating to Flexible Circuits
Ideally, for a low profile and a neat finish, it is
best to terminate flexible circuits in line with
the contacts. Since most Microminiature
connectors have contacts set into two or
three rows, termination is a simple process.
The diagrams opposite are basically a design
guide for pad arrangements, to suit MDM con-
nectors in particular and to ensure the circuits
enter the potting well. The length of the pad is
optional but of course it is important to pro-
vide enough coverlay, especially at the edges
of the circuit, to avoid de-lamination. We sug-
gest at least 0,51 mm (.020 inches). Our stan-
dard potting shrouds provide support to the
circuit with a dimension of 7,00 mm (.275
inches) from the rear of the flange.
Please consult Customer Service for specific
flex circuit assembly design considerations
and requirements.

Diagram 2 illustrates how the connector is
prepared with short pigtails and a special first
pot which just captures the contacts. The final
back potting for strength is controlled by our
standard 7,00 (.275) potting fixtures.
