We use the Gel Flex from MPM. Made a different base for each machine. Works well for most boards, but you may need additional pin support for larger boards. No tools, no vaccum hoses, no missprints (which Grid Lock is famous for), and best of all

Here's another outfit that makes a board support system: http://www.production-solutions.com/ The Gel-Flex may fit in a DEK. The gel blocks and pins in the kit are 4cm high. Not sure what the centernest depth (from conveyor belt to bottom plate) i

Yes. I used to use em on our old 286. The side clamps work very well with them and our missing parts from support pin problem went away. It was our #1 defect a few years ago. 100%ing work orders for missing parts sucks.

Hi. We have a medium to high volyme production with a lot of different boards to run inour lines. We do some prototypes as well but not as our main production. We have a lot of change over time that we try to reduce and as far as it's not double side

Hey, where's the 0201s? Just kidding. Off the top of my head, I do not recall seeing results of such a test. Nonetheless, I�ll consult with my peers and let you know if we come up with something that could assist you. That said, with a few more d

We are printing 0.012" apertures on a .012" Solder mask defined pad in a fine pitch BGA application. The board is 0.032" thick with very little room on the bottom to place support pins under these areas. Our first pilot proved extremely difficult to

You provided excellent detail, and unfortunately I do not see anything out of the ordinary except the tooling issue. This brings us back to the original tooling related questions you had asked before. My apologies for questioning your process integ

Thanks for the insight. Most boards we are seeing problems with are 1.60mm thick (some less) and most of them are panelized. For your support pins what do you use to show operators where the pins should be setup? I have heard of using Plexiglas to m
