I was talking with my Paste and Flux Supplier about concerns of coating over "No-Clean" flux.
Supplier informs me that this should not be a problem, but I wanted to poll the industry.
1. Does anyone here conformal coat over No-Clean? If so what do you use Acrylic, Urethane, Silicone or Blend?
2. Have you had any major problems doing so? No adhesion or Low adhesion?
3. Does anyone have long term reliability data of this process?
Thanks Everyone!
