REFLOW SOLDERING OF THROUGH-HOLE COMPONENTS | 24 June, 2002

I was reading an article on reflow soldering of through-hole components today under the "knowledge base" section. I would like to hear from any of the SMTA members if their company is presently using this approach and their success. I would appreciate hearing from anyone on this subject. Thanks!

REFLOW SOLDERING OF THROUGH-HOLE COMPONENTS | 24 June, 2002

I have done experiments on small runs, with a few connectors and have had favorable results, I had apertures (oversized)made for the thru-hole connectors on our SMT stencil and hand inserted the connectors.. A few insufficient solders here and there but it was better than hand soldering each connector by far. On one particular board I had a thru-hole connector with 25mil centers(or about) dual row 20 pin. Once again the board had some innsufficient solder areas but overall.. reflowing them beat handsoldering easily. One of the issues with relfow soldering thru-hole devices is temperature sensitivity, so make sure look at the manufacturing spec of each component you intend to try it on.. GLUCK

We've talked about it a fair amount here on SMTnet. Search the fine SMTnet Archives for background. People use a variety on names to talk about this. Common names are: * Paste in hole [PIH] * Pin & paste

It does work, but you must keep in mind that not only the stencil must be designed for it, but also the board. Trying to use the pin-in-paste process for a connector with an ordinary wave-solder layout will result in lots of touch-up. You'll need smaller holes, larger spots and the materials must withstand the higher temperatures. An technical article about pin-in-paste soldering is on http://www.amp.com/products/technology/articles/dd66.stm

You also need to take into consideration the print angle. Contact your screen printer manufacturer for specs.
