Bill,
I'm just a generalist, not a cleaning expert or a component guru.  First, a
point of clarification, by roll solder do you mean wire solder? Second, why
did they voice concern? I mean if you are using no-cleans then why in the
world are you cleaning at all?  If you HAVE to clean, then why not use amore
active fluxes that are meant to be cleaned? And finally what is the concern
about RF parts?

Subject: [TN] Cleaning PCB Assemblies

Hi Folks!!  Could use some help.  We are a contract mfg. using no-clean
solder paste and roll solder
for secondary ops and touch-up.  Some of the PCB assemblies contain RF
components and we have
had a customer voice some concerns regarding our cleaning (using EnSolv).
Have heard that new
chemistries with a aqueous washing system have been successful.  Have also
heard a vapor degreaser
works well but not the greatest choice with RF components.

Would appreciate being pointed in the right direction.

Thanks in advance for your help!!!!!

Regards,
Bill
