Thanks Dave! I'll see if I can find the standard on IPC's website or inhouse (our company) if I am lucky. I appreciate it. What type of flux are you guys using? No clean? or Water-soluble?

Yes. I agree with the previous comments. If you will switch to Water Soluble Flux you need an Aqeous Cleaner.

What are the specifications on the solder that you use? IE: Water soluble,RA,RMA, N/C? Also do you clean the boards and if so how and what detergent if any are you using?

Does any one have the best recommendation for a water soluble solder paste for use with fine pitch parts and micro BGA's and immersion gold pads.

Hey, We have introduced a Cleaning Pen from Chemtronics. It removes excess flux after touch up.. This way the operator doesn't have to go everytime to the cleaning room.. Indy

Use Water soluble if you can, if not I would try the Indium SMQ NC paste, this residue stays soft. I would also change ICT probes to the "drill type". Russ

use water soluble solder paste is the cure for your problem. but if you insist of using NC change your pogo pins to pointed pins.

A customer of mine is having problem. They can't control their humidity. It is very dry. RH averages 28-30%. The water soluble solder paste prints great. But dries out on metal squeegee. Any suggestions.

Don't know of anything really automated, Winslow Automation offers solder spheres on water soluble tape and a company called the Waveroom Plus in NH offers a machine reasonably priced but it is not automated. There are companies out there that offer

They can be expensive and if your using water soluble chemistry you will have to immerse the pre-form into flux. Asking the vendor to provide flux with the pre-form I believe it would dry out prior to use.
