Esoderberg, Thank you for the response! I was completely unaware that HumiSeal provided latex masking. I have a sample on the way. I sampled some Wondermask 2211 in the past. By the TDS description, I wonder if they share the same makeup; both

Hi all, We have an assembly which features non-plated tooling holes used to align the board in a bed of nails style test fixture. This assembly is rather small, and as such, the test points are pretty small as well. We have found that some variation
