Has anyone had any success with placing BGAs with the Quad QSP-2? We have been having alignment issues with BGA placement but our placement of 0402 parts is dead on. We have worked through the calibration and it seems to be correct.

They have there strong points and weak ones. I have worked with them for the last 5 years and have seen some flakey problems (Cables, feeders, encoders) that will cause you some down time but if you get a good price on a system it might be worth it.

Quad4C's have their moments. If the price is right and you are aware of the machines limitations then you will be satisfied. The placement rate is slow, 1.2 seconds/chip. Don't buy any Quad if it has the CyberOptics Laser unit, the Quadalign unit is

Additionally, I have seen the bad align error from incorrect pickup Z. Quad align can freak out sometimes if it sees something it doesn't like. If all else fails I just reboot and 99% of the time the problem goes away.

I have seen the bad alignment error many times and never had to replace the head for it. It usually has something to do with the laser windows being dirty or cracked. Also it could be your profile settings. Make sure all of these things are perfect b

Help! Since last Friday i have been having issues with a Quad qsv-1, it all started with a quad align error, i found there to be a small quantity of grease covering the lenses on both quad align sensors. I wiped the grease off and then everything s

Thanks for the info. I called Mike Tieman earlier and he recommended I do the exact same things. He said that there should be very little resistance on the theta of the Z-rods, (not the case) so he recommended that the P4 head be replaced. Mike is

Here is a few things to try.... 1. Spin the z-shaft with your fingers and make sure it is smooth and easy to turn. 2. Check your handling in your profile for the part that the software is locking up on.......You cannot go any slower than 40% or this

It's not the z pickup or profile bot thanks for the help, I think Mike is right. I have used these profiles hundreds if not thousands of times in the past and never had an issue. Also it was different components and different profiles almost every ti

I think I have the vision problems figured out. There were two problems. 1) The Alignment type was set to "Small" for my TQFP48 part. It should have been set to "Complete". This is a clear case of poor documentation. The AutoProgram manual lists the
