SMT Question

[djmiyta]

I am using metal tweezers for putting the SMT in place I noticed there is a slight magnetism to them I soldering 2N5457 and J201 would that little bit of magnetism do any damage to the chips?

No. Do not worry, sleep well.

And now I can Thank you

If at all, you should be concerned about electrostatic discharge. Some transistors are quite susceptible to failure in this regard. I don't remember exactly which models now, but I think the 2N7000 was among them. I've already fried one or two. Not sure when and how - probably when handling or soldering. But those are only two units I've damaged when handling/soldering/using. No other victims to report

Good to know about the 2N7000 and I’m pretty cautious about IC and trans but I’m new to SMT stuff and I don’t think SMT is going anywhere soon so might as well embrace it. There’s some guys out there doing amazing stuff with SMT a guy named JOK3ER (I think) did a tight metal pedal that was outstanding

I’m actually looking for why after soldering J201s and putting them in the PAL800 I can bias them but can only get a clean signal thought maybe I fried them so I’m thinking now I got a wrong value in there somewhere since chances are slim I fried one and I also tried by ear no crunch
