Thanks for the input Guys Yeah the not so knowledgable customer does not like to residues for cosmetic resons. The flux is for lead free process, of the no clean and water soluable type. We have explained to him that technically the residues do not

You can use straight forward Tin/Copper but it flows very poorly so solderability is an issue. Dosing with Phos improves this but need to stay on top of it. We have supplied some 3.8%Ag alloys for flow they work well but you get a small 'chill point'

Ther is a solder alloy out there that is supposed to allow lead free wave processing without having to upgrade pumps and such or increasing the pot temp (direct drop in). I have not used it nor do I plan on doing leadfree wave soldering but you may

Hi Pete, The boards are HASL. The frequency is random. The solder balls are randomly deposited along the path of the select wave, not always along the component bodies. We are very careful regarding handling. There could have been contamination on s

As with any issue like this, your miileage may vary with suggestions....but, here are the items I would consider: 1. Clinch tightness. I believe IPC gives a recommendation on the amount of bend in a clinched lead; make sure you're not beyond that.
