4. There is a possibility that your company have more than one vendor for a specific component (same partnumber for you but different mfg. part nr). Let say that it is a red led and this itself could be somewhat tricky to order: Red led is as most of

Does anyone have the same issue as i do with component markings?? I am using a AOI machine to inspect and the parts that our girl buys are a mess. the ink is smeared and not readable. I was told there is no quality level when you buy parts. Doe

Polarity for SMT Devices

Silkscreening is falling out of favor, as it should. SMT IC devices can have their "pin one" solder lands indicated by a round mark, like a fiducial or a "1" mark, both made from either the copper clad PWB material or silkscreened. I have seen some w

That is the rub here, isn�t it? For those posting, it�s easier [but much slower] to start a new thread than to search the archives. [And posters could view their issue so unique and novel that it could never have been discussed several years earlie

Hi Guys, I have a little keyfob that one of the buttons has stopped working. I have been trying to diagnose the fault and think I have found the offending component. It looks like one of the diodes is chipped slightly. I have also checked the resis

For laser marking you don�t require as powerful lasers then for cutting. A 20 Watt laser diode does already a good job. Because of the safety requirements the laser operates in an enclosure, which means more $$$ if you want to use the laser in line

Defect in diode(Reverse Polarity)

If it was only 1 or 2 components on a reel that were backwards, I would lean more likely the cause just being the component was wrong direction in Tape from factory. Not much you can do from a Pick & Place perspective, generally.. Most machines use

I tried to look for "H890" on Internet and went nuts, (Thanks to Google) I would think H890 is part of a diode manufacturer part number. Have you tested it for a diode function? or maybe you have this is why you want a replacement. Tantalum capacito

The transistor on your Audiovox VE926 Commax CL-70MA board is double marked. You are looking for a "DF S2N" You're not the first with this problem. Look here for leads: * http://www.fixya.com/support/t404099-audiovoxve926_no_picture * http://www.f
