In the past year I was responsible for developing and leading a Team focused on AOI, Evaluation, Justification, and with a full ROI required, supporting a HMLV manufacturing environment. If you have in these economic times the additional resources t

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.

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

As an AOI operator as well, I can see your point, but what about 0402 parts, and all chip capacitors? These parts are not marked, but I presume you accept those? In relaity, an unmarked resistor is no different to any cap, and you don't worry about t

From my perspective, I like marked parts because I can use AOI to verify the correct parts are being placed in production. If an operator is going to load the wrong reel, I prefer to find out on the first PCB rather than after 5000 wrong parts have b

Are the markings on resistors the actual value? Do AOI machines look for these markings or do they just look to see if a component is present and placed well? Can anyone attest to the solderability of upside down resistors? Can anyone argue that u

Hi is me again If what you are looking is for the AOI to "see" the marking on a resistor theres the option of taking a picture of only the numbers in the resistor is not highly accurate but it works.

The Universal chipshooter (Sanyo) has automatic X-Y pick-up correction as standard. Are the upside-down resistors an issue for inspection purposes? Do you use AOI? Can you really read markings on 0402 resistors?
