| I am looking for information regarding post wave soldering of stranded wires into a circuit board using OA core wire solder. We do a final pass thru the cleaner after the hand soldering but I'm concerned about any OA flux residue that may have wic

| | With current soldering of stranded wires to pcb assy's the wire tends to be very brittle and can break with very little movement of the wire. We use a low residue cored wire. Anybody with advice or who has seen a similar problem/knows how to over

Dear Sanjay, An important issue involved when stencil printing adhesives vs. solder paste is: How do you clean the stencils after printing? Do you need two machines? Two chemistries? Two waste streams? What are the potential environmental impacts an

Thank you Steve for your input it was very usefull. I think I skipped a few pertinant details on my initial message though, the component which we found the flux contamination on was on the top side of the board, I was curious if the flux could come

Wayne, I think Dave and Justin are correct but I would just add my twopennworth: Your customer presumably wants to know if the end-product will be reliable? If he/she wants you to prove cleanliness, ask them for the spec they want to work to and app

OK, I'll take a little abuse as long as you guys are giving me all this great advice. I am concerned about what might happen when a drop here and there comes from the connectors and is absorbed into the box. The box is going to suffer from this. I am
