| Clarissa, | | Dave had good suggestions. We load several boards manual at this time. We set our components up in clearly marked bins. The documentation includes a chart with the part number, bin number, reference designator and color code for t

Writing the final report for my engineering studies (microsystem technology) I'm treating the identification of PCBs from automotive applications by laser marking with a data matrix code. No I'm trying to set up a programme of how to test the lifet

| Looking for a cross-referencing and part identification guide for surface-mount components. There is very little infomation provided on some of the components themselves, and we often don't have parts lists or schematics for items we repair, so ide

First, why is there appears to be no marking on simple capacitors when there is a code for, yet there is markings on resistors? Attached is a interesting table, it came about after I spent hours and hours and hours looking on Internet from a 16 Volt

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

I think you need some new suppliers. Any reputable supplier will have the M-code marked on the outside of the pkg, as that's a req't of J-STD-033. So if it ain't there, tell them they need to properly mark the pkg. Them telling you to "check the i

It just looks like a transformer, as had been mentioned earlier, but w/o a part number (usually the parts are marked with some ID code) it's hard to know for sure. If that's the case and what we're seeing is one of the leads for the windings that c

We use preprinted labels and laser coding. For PCB we laser mark with CO2 (NdYAG for the aluminum heat spreaders). We either have an epoxy legend to burn out or we burn the solder mask to expose the copper ground plane underneath. Laser is a much
