D Connectors on both sides

D Connectors on both sides | 9 September, 2008

We are quoting a job that has about 30 50 pin D connectors on one side of the board, and about 10 on the other side. Barring any stroke of genius, we would wave solder one side, and hand solder the other side. Does anyone have any suggestions on how we could wave solder both sides? Thanks

Only with selective solding. Those would be too tall to do a second wave.

We'd use a hot air gun like a Leister [800-700-6894 http://www.hotairtools.com/products.htm] hot air soldering tool with a nozzle for your connector.

We have no relationship, nor receive benefit from the company referenced above.

If the connectors can withstand reflow temperatures you might consider solder preforms. I have personally never tried them. I beleive that you can get them in any configuration desired. Indium and Alpha are some suppliers that I am aware of.

Again, if the connectors can stand reflow temperatures you have the option of intrusive reflow (pin in paste)where you print paste over the holes for one of the connectors. I have did this before on a slightly different type of connector. Works pretty well.
