I'd tried pretty much every existing mounting compound and ended up using Struers one for many years. ------Original Message------ From: Ramakrishnan Saravanan Sender: TechNet To: [log in to unmask] ReplyTo: TechNet E-Mail Forum ReplyTo: Ramakrishnan Saravanan 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 ?. regards, R.Saravanan Regards, Vladimir SENTEC Testing Laboratory Inc. 11 Canadian Road, Unit 7.
