Driver glue?

So I had a L08 which came new not functioning. A little probing revealed a dead XPG which I promptly swapped to a 219B SW40 (a little cooler than I care for but its what I had and is similar to the sw45 they came optioned with). In the process I had to loosen the driver board which turned out to not just be fiction fit but also had a generous dollop of glue holding it in place- it was pretty weak though so probably one of those mild thermal adhesives. Trying to decide what I want to resecure the board using.

- Super glue

- RTV

- E6000

- 832HD thermal potting compound

  • something else

The first three options I do have on hand, although I think we can rule super glue out… well it would probably work but I’m not using it. I’m actually leaning towards potting it with the 832HD but I would really like the option of modding later if desired. Although, truth be told, I don’t think its very likely as this is very large for a AAA host and the driver is kind of unique at 13.5mm and requiring electrical isolation from the pill. I have some thermal glue in the mail, but no idea when it will arrive.

I used superglue to good effect on an Emisar D4. The glue is only needed to stop the driver board rotating when the body tube is screwed in. On purpose, I didn’t clean the surfaces too carefully first, and I used the tiniest two drops I could manage - all intended to ensure the grip was sufficient for the purpose but not too much of an impediment to breaking it out again if needed. As it happened, I did open it again a few months later, and that went just as I hoped.

I can confirm E6000 will bond a PCB to bare brass pretty well (from experience). Just let it cure for over 24 hours - preferably 72.

Well, I’m going to give this a try. Put a couple of micro-tabs on the rim of the driver PCB and clamped it. Seemed safer than dribbling cynoacrylate all over.
