I've seen this done on RS232 connectors before. I've opened up a few USB-Serial converters and all have soldered the top row of pins to the top of the board and vice versa. It seemed strong enough and I don't see why it wouldn't work for pin headers. --=20 Brendan Gillatt http://www.brendangillatt.co.uk --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
