I'd tried pretty much every existing mounting compound and ended up using Struers one for many years.

Subject: [TN] Hot mounting micro section of PCB
Sent: Jan 4, 2013 11:23
We are making space quality MLBs. We are using hot mounting for micro section.
My understanding is hot mounting(Phenolic power of Buehler at 150 Deg C ,180 bar & 5 minutes) of PCB specimen will destroy the PCB specimen Our metallographers are against using cold mounting. The reason is they claim poor edge retention & high shrinkage and observing faults are difficult.
Which method of mounting is best for micro sectioning PCB ?. Which is the best resin & hardener having low shrinkage and high edge retention ?.

R.Saravanan
