I was wondering IF anybody has has success wave soldering a 50 (2 rows of 25) pin 0.050" pitch thru-hole connector. I seem to be getting alot of bridging no matter what I do. Is there a design spec for the size and shape of pads? The pads on the pcb

I can't help you with your soldering problem, but I wonder if a pressfit connector is an option for you. If this connector is available as pressfit, you can avoid the solder wave proces and associated problems. Write me if you are interested in more

Try to insert thin copper plate (approx. 1.5mm thk) at the end of the flow direction. Place it approx. 2mm away from the lead. The copper will pull away the solder & thus minimise bridging problem.

This "thieving" idea is a good one. There is a SMTnet thread on connector thiefs from a coupla years ago that you might check.

1) Try to keep lead as short as possible. 2) The long side of the connector in the direction of conveyor. 3) Use pallet, design such that the connector is 45 degree to the wave.( or conveyor). May not remove all shorts but reduce to one area i.e. th

If the package is robust enough to handle surface mount followed by a pass through the wave soldering process, we have had excellent results populating the fine pitch parts with the P&P machine, reflow, then mask the solder joints prior to wave solde

Is it possible to wave .02mm fine pitch? I get excessive bridging. Any ideas welcome. Thanks Brian

Most companies are double sided paste and reflow, then selective soldering the thru-hole. This will give you the best results and with much more consistency than with Wave Soldering.

I think you have your pitch wrong but anyway, I have never had success with wave soldering anything less than 50 mil pitch. On a QFP I have had good luck on three sides of 25 mil but never all four sides and without defects. Mask 'em off and hand s

Are you talking 0.02" (1.225mm) if so then no it's not a great idea. if you must wave it can you go to a PLCC and through hole socket it on the other side of the board?
