Replacing fets with wire glue

[xzc426]

I burnt out my forward fet (and it's repacement fet) a while back and I'm getting around to replacing it. I burned the stock fet because I dragged a hot wire across it, and the replacement because I held the soldering iron on too long (I think), so I'm a bit paranoid to solder on a fet.

So I was wondering if wire glue works fine on fets. Or is there a good reason I should stick to soldering?

Thanks.

I guess wire glue would work but I'm not 100% sure, the glue is non-conductive so it wouldn't matter if you used a little to much but because its non-conductive your FET legs would have to be right on the money to ensure a bridge, not sure how reliable the glue would be for that.

i'm pretty sure that it won't work period because as B1G said,the glue is non-conductive and one side of each fet needs to be bridged.
all four pins need to be connected to complete the circuit.

if you're unsure of you're soldering skills then i do believe that XXXmodder will work on your fets for the cost of shipping.
a small,padded envelope and shipping to/from just about anywhere in the USA is under $3
check out his service thread and shoot him a PM.

actionB also does this kind of work but i havn't seen him online much.

good luck with it.

Certainly you should stick to soldering. If the board is still fine just give it another shot if you feel comfortable. I mean FETs don't cost THAT much. Are you trying to upgrade or replace with stock ones?

Keep the burnt up FETs to practice with. Go to RS and get a roll of de-soldering braid and you can keep reusing those FETs to practice with. In the meantime if you have the replacement FETs I will do them for shipping cost. If you need new FETs then it is $15 per 2 FET stack. ActionB is also available for FET service but speak to him on his prices and options. Just shoot a PM.

I agree.... Don't use wire glue. No good.

Wire glue is actually highly conductive (as per their website) but the problem that is unknown is how much heat it could withstand (and I doubt it's very much). The fet legs are the highest current drawing component on the board so I agree with Bondo and B1G and everyone else to stick to solder.

alright, thanks guys. Looks like I'll be giving soldering another shot.
