The problem that we have seen applying NC flux (EF2210) at selective solder is that the flux overspray (relative to the nozzle path) did not see high enough temperature to activate the flux and turn it to a non-conductive, benign residue as one would

You really need your customer to provide a drawing of coated, keep out, and don't care. People new to coating don't realise the importance of having a don't care buffer area around the keep out areas. And conformal coating wicks up leads quite easil

Mike, we use a product called Dow Corning 321 dryfilm lubricant. BTU reccomends it. You can find it in Mcmaster Carr for about 21.00 a can. Mcmaster PN is 1255K14. I reccomend pulling the chain off when you are lubricating it to avoid over-spray. Th

Thanks Real Chunks. We currently have an RPS opus selective solder machine that we plan on keeping. It is configured as a 3-nozzle (!) one-pump (!!) point selective solder machine w/ nitrogen preheat. Custom wet nozzles. We use lead free SN100C sold

I presume you have a local flux spray with your selective solder machine (I have no idea what you use). If I have a group of leads in close proximity like this, I would be trying to design a well and nozzle setup that I can use to solder all the joi
