See IPC 610 for this. Section 9, there are a lot of conditions so I will not post here Russ

Perhaps there is someone who can answer this question. If a 1k 1% 0805 ohm resistor is missing a corner is it still going to read 1K ohm? Or, if it has an extra bit of material is it going to read more than 1k ohm? I am guessing that when chip reisis

Hi John, They may still read the correct value initially, but they are not going to age well if the electrodes start oxidising. Also the high voltage surge performance & the impedance are likely to be effected, however these may be unimportant to y

The difference is that our customer expected these resistors to be marked, and Panasonic's documentation online is inadequate to prove otherwise.

Is the industry really moving toward unmarked chip resistors? I've been seeing a lot of unmarked 0603 resistors lately, and when I check the data sheets, all their photos are of marked parts, and they don't say anything about it.

Our AOI machines have actually caught wrong resistors before. A reel gets swapped, a vendor sends a wrong part, things happen. To think that we can't rely on resistor markings anymore, that just sucks.

It gets tricky when resistors that your customer specified are no longer marked, but they think that unmarked resistors are a defect, and the manufacturer hasn't updated their data sheet to show the parts as unmarked, so you don't have anything to sh

Yageo announced their decision to stop marking SMD resistors back in 2013, and since then we have started to see 0603's that aren't marked, but larger sizes - so far - are still showing a value. 0402's have never been marked, and I doubt they ever w

Looking for non magnetic 1% surface mount resistors. Does anyone have a clue where to find them?

Absolutely - it is probably cheaper! Soon they might start doing it with the transistors, diodes and ICs too. Why would you need a sophisticated AOI machine then? What would quality control look for? It is annoying, considering the amount of differen
