Terry,
Did you get any respons? Interesting finegrade work. But your project
seems little 'homebuilt' or more correct an emergency solutions.
Depending on how large your board is, I would use a 'Gregory' solution,
i.e. kind of a twin flat steel (for ovens)band, bend both ends to small
hooks and bend the hole to a low 'V' which will force the pieces against
each other. If the band goes continously from PP to oven it may be a
less good idea. 

ELCO makes these connectors.

Ämne: [TN] SMT Connector Assembly Question

Technet;

I have a fine pitch single sided 50 pin edge connector to assemble onto
the edge of a PCB. It overhangs the PCB edge.
This is a SMT which is pick & placed from a reel.

Actually this is a single-sided 50 pin Compact Flash Connector from AVX
Series 5611 Receptacle Connector.

This PCB is panelized. This connector has 2 supports on each side but
the support plane is at the same Datum as the PCB bottom side
( DATUM A).
So the panel must have a milled out pocket for this connector to sit in.

Question is;
What is the best way to support this connector during pick & place, then
into reflow?
The pocket above is only a clearance & provides no support to hold the
connector in place.

The only thing I see now is having a bare FR4 panel underneath this PCB
to provide support for the connector.

Any thoughts are much appreciated.

Regards
Terry (TDK)
