Pick up correction (as far as position) is already available on newer model chipshooters. This doesn't address upside-down fed resistors. The link I provided for Murata tells a story of increased reliability and reduced cost. As components get sma

Application...oh, we are a high volume, low mix (HVLM). Forgot to answer that one earlier.

Why don't the component manufacturers simply mark the values on both sides of the resistor? Can't be that difficult.

Claude, I know alot of equipment manufacturers that would like to talk to you about replacing all of your chipshooters! Of course, this will never happen. There probably won't be any sold until all of the used chipshooters are absorbed from the use

I do not know about the cost issues but as I recall the tolerances are tighter on bulk components and this usually means higher cost. I cannot find my bulk feeding summit information but these links give you some idea what was discussed. I don't kn

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?

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

I don't think it's possible for a turret machine, but I seem to remember some sales guy talking about a camera on his machine that did look at the part before it picked it up. As far as bulk feeding goes, how would you ensure the resistors are right

Sure they'll do it...If you're willing to pay double or triple the cost. It might not be as easy as you think. the value is usually marked in white over the black carbon area that actually is the resistor. Underneath is just the white ceramic carr

Has anyone actually seen 0402 or 0201 part with the value on it? I haven't. So what would be the big deal if these parts are placed upside down. The only difference I have noticed is usually on a resistor one side is black and the other is white an
