Effects of acid etching on different 2024 tempers

Hello everyone. My name's Frank Woodcock and I work for an electronics manufacturing facility. One of the products we manufacture makes use of an aluminum base plate (our specification allows us to use either 2024 T3 or 2024 T351). To allow the units to be encapsulated in epoxy, we have the plates acid etched to give the epoxy something to grip. I was wondering what, if any, difference the temper has on the acid etching? I believe right now our supplier is giving us the 2024 T3 alum. Thanks.

Dear Frank

You would get much better results if you just had them chem filmed to MIL-DTL-5541 [on DLA].
