| I've heard about these reflow temperature labels/stickers but haven't seem to find them. Is there such a thing? And how reliable are they? I don't want to keep attaching thermocouple probes onto a board whenever there's a issue. | I think you are

Re: Why so little interest in Bulk Fed passives?

Electronics Forum | Fri Jan 08 09:25:40 EST 1999 | H. van Leeuwen

| If passive componets are cheaper why aren't they more popular? Manufacturers like Murata and AVX claim availability and substantial cost savings but little interest seems to exist. Why? Your input is greatly appreciated. | Good question... I work

Re: Does Fuji have adaptive pick?

Electronics Forum | Wed Dec 23 22:00:50 EST 1998 | Phillip Hunter
