Hello All, I've just bought a Quad 4c pick & place machine. It's so close to actually building boards, but just doesn't quite get there. I was wondering if there's somebody out there with experience of these machines that might be able to help...?

Hi again Bobpan, One thing I noticed when I pulled the z-rod to inspect it was that it was "bearly" finger tight. When I replaced it, I snugged it a bit better (not overtightening). After resuming setting up additioanl placements (this board requires

POCKET POSITION PROGRAMMING This procedure ensures the components are properly centered at the tape feeder pickup point (over spring stabilizer). NOTE: The feeder can be reset at any time by removing it from the feeder base and reinserting it. This

Well, everything WAS going OK until I started setting up for a board job (40 boards with about 450 components each - many image repeats). We setup 37 feeders with their parts and started defining the pickups and placements. Part #1 is an SOD123 zener

Hello Bobpan, Thanks for the suggestions. Sorry I didn't reply yesterday as I'd gone home - I'm in the UK, so I'm guessing there's a time difference. Okay, I found the control to turn off the vacuum verify - it's SHIFT - SWITCH/VERIFY. Makes no di

This doesn't help the original poster any, but does the Quad have any sensing of what is going on in the feeder? On the pneumatic or mechanical Philips feeders, if the tape jams in the feeder for some reason, the head just keeps tapping the lever an

Hi Bobpan, Regarding "second", the results of the test are no difference - still rejects the part. I tried 2 mils, 3 mils, 5 mils, 7 & 9. I changed the tolerances fron about 15% to 20%+. By the way, I did put on the new nozzle and it is still the sa

bobpan, It only happens with this program. CC ver 7.54, IVC V 3.05 If i leave CC out of it, and edit the sequence using the HHT, it sticks. but if i download from the assembler to CC, it's messed up. if i then fix it in CC, the minute i save

Hey Steve, I wrote to Bob, but he doesn't reply yet. Digging around, I found these: HANDLING COMPONENT VARIETY The adjustable Pocket Index function enables handling a variety of component tape reels or special component packaging. The following ins
