We use those little spring loaded test terminals into a pth hole the
ones with a spear point and a scrap pcb underneath them they go in on a
0.1 pitch. Ew also disconnect the VCC and the data lines with little
jumpers until the program is finished (the programmer cant handle the
currents of the whole circuit often so it only powers the device

Subject: [EE:] ICSP in production runs - connectors?

Hi all,

A question.  I'm about to do a design for production (meaning runs of
100, for now anyway) and wonder how to provide for ICSP of the PIC.  It
will probably be a 12F part, if it matters.  I don't want to have a row
of header pins, nor any sort of cutout for connecting a card-edge type
connector (rectangular pcb with nothing fancy is cheapest).  I'm
thinking something along the lines of some pads at the pcb edge with two
holes such that some kind of small 5-pin connector can be placed on the
pcb (with the holes matching up to bosses on the connector), the
operator hits program in MPLAB while holding the connector down, then on
to the next board.

The PIC will hopefully be an 8-pin SOIC device; 14 pin if the design
requires it.

Would some sort of spring-loaded clamp onto the PIC be preferred?

How do people do this?

All suggestions welcome!
Thanks everyone
Jesse

p.s. and thank you PIClister whose funny .sig I swiped.  :)
