Epoxy on Main Logic Board to prevent hacking??? | 22 September, 2003

Help Please!

A friend of mine works for this company (a novice in the hardware world), they are thinking about covering their PCBAs with Epoxy (don't know what) so to prevent hackers from damaging their PCBAs - they claim it is costing them too much as these PCBAs are slipping through retail chain under warranty. My questions are: 1- What kind of Epxoy that would prevent an intent hacker from damaging a board? 2- The PCBAs are being reworked today at service locations worldwide, when Epoxy is heated, wouldn't this present a safety problem for the rework technicians (inhaling toxic fumes)? 3- What type of rework equipment would be used, assuming that this Epoxy is similar to conformal coating in marine PCBAs?

Any information is highly appreciated. Thanks, Joe
