| How can solve the small solder ball after w/s. (oxygen level is 40000~5000ppm, no-clean flux & Tamura N2 w/s machine). Post your question in the SMT Forum for a better response. This area is not for tech questions.

We are getting solder balls after reflow of surface mount components. We are using a no-clean paste and a new jar seemed to help for a little bit. Any ideas? Thanks in advance

| We currently bake plastic SMT parts in accordance with the IPC guidelines for moisture sensitive parts. Because we have double-sided boards that are subjected to either an aqueous or semi-aqueous cleaning process, we do a 24 hour bake at 125 deg.

We notice that DI water seems to tarnish or discolor the metal packaging on crystals and DIN connectors. Our marketing types like the shiney metal surfaces. We don't want to hand solder these parts after washing. Any suggestions? Dave F

Any ideas on what to buy? Only need to build surface mount protos, ability to rework. Is a rework station okay? Will subcontract production after design is proven.
