Thermal Adhesive ?

If it's white paste, it's just thermal grease, it'll stick pretty good due to surface tension but it's not glue. If it's dried up, scrub it all off and smear on a thin even coat of new stuff before you put it back together.

Hey everybody:

I'm trying to get at a switch in the back of a powered speaker, and in order to do this, I need to remove the entire circuit board from its enclosure.

After unscrewing every screw I could find, the board wouldn't budge, and it seems that it's glued to the case by its huge heatsinks by what I assume is thermal adhesive.

So my question is: do I just wedge a screwdriver in there and rip it away? And after I do figure out how to get this thing off, I assume I'll need to buy some more "glue" and put it on there? Is that as simple as it sounds? Will I have trouble figuring out what to buy?

Thanks in advance.

I've replaced tweeters on two sets of speakers and I've fixed a DC socket on a synth. I know how to use a DMM, but my oscilloscope is the crappy one that uses a PC soundcard. I've built a synth from a kit, and I'm starting to make a binary LED clock from nothing but the schematic. I took a semester or 2 of EE in college a long time ago, and read a couple of books.

Hope that's neither too much nor too little info to answer your question!

I can't say that this is a good idea then. I would apply careful steady pressure to see if the heatsink paste gives, but it takes experience to know when things will break.
