Subject: [TN] Solder Mask over Tin Lead Plating
Hi,
We received few PCBs from an European PCB manufacturer for Aerospace Industry. I am surprised to see Solder Mask is applied over tin lead plated tracks. My understanding is if u do reflow , the solder under the mask will melt and affect the mask. The correct method is applying Soldermask over bare copper isn't?. Kindly advise. regards,
R.Saravanan
