After an in depth examination, I found that the problem was not a defective connector as I thought in the first place. Actually is a broken through-hole on the Quad Align sensor. I requested a spare part to PPM. Mr. Bobpan, thank you again.

the glass is to keep dust out. Now that it is off the dust is already in. Leave the glass off and just run it. If you have a problem 6 months down the road then take dry air and blow it out.

Dont quote me on this because its been a while but i believe thats a grounding issue on the quad-align card itself. The card is located in the rear right bottom of the machine. Try adding a ground wire to the cage that the card is mounted inside. Als

Tim, 1. You dont need the vacuum verify if the quadalign is working properly. If you have the part quad-aligned and dont have alignment type at 0 it will never 'not' place a part. More or less...the vac verify was needed for the chucking machine (3c)

Thanks for the quick reply :) We've used some classic feeders that we repurposed ourselves by switching the original optical barriers (index wheel and motor wheel) with twice the resolution. It gives okayish results, not great, but the 0402 is alig

So, I haven't used my Quad 4C for a while and when I started everything back up to run a new board it appears that the Quad align is in need of calibration. When I pick up a component and do an LAE measurement on it it shows the part center location

I am using ver 6.50 software. Do you know Quad Align compared to Cyber or Samsung's own, which is better? Do you know if the QSA30V support non-symatrical Micro-BGA such as DDR2 DRAM IC?

Quad Align.....Cyber-optics....no difference...they both work well. Never tried a micro-bga but i know the upward camera does standard bga parts.

Error we get is quadalign. Calibration is good. Signal for this head appears better than #2 which works fine. As soon as 1 picks up the first part we get quadalign error. Thanks for any help you may have. Andy

Have you tried turning the theta manually to feel if it is stiff or having a harder time turning. This will cause Quadalign errors. also be sure the handling is not set to 10% on the theta this is also a problem.
