Board support | 8 November, 2007

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 boards there is no problem to make support that is easy and fast to change, the problem are the double side ones. We have in one of our DEK printers a Grid Lock system that works well but the price for it is just a bit to much we think. We need to find a system to put into our printers and our Fuji QP 242 machines (they are a pain to set support pins in) and I'm just curious to hear if you have any other system that you use and that you think works nice for this. There is a system called VacuNest, has anyone tried that one? Regards Joakim.

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 - no over weight sweating technicians!

Can these be used on Dek printers ?

Here's another outfit that makes a board support system:

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) is on a DEK.

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.

Thanks for that, now I have some more targets on Productronica next week.

NOTHING! As long as you don't drip sweat on the boards you're trying to set-up and then re-adjust and re-adjust and re-adjust all day long like you get with Grid-Shlock.

Being a hypochondriac and a pus*y, you would probably go to the emergency room if you EVER got grease on your hand (some skin disease). So your input on what a tech. (or anyone else who might happen to turn a wrench, leave the computer or actually watch the machines run) should be taken for what it's worth! Evidently expertise is directly proportional to time spent under the boss' desk or at your plush executive office. Don't hate the people who actually do things.........they are the reason you don't!

We have been using Grid Loks on our MPM Accuflex machines and see an offset in the print every so often. Haven't been able to isolate the problem. How bad was the misprint and how was it related to the grid loks?

Thanks

N ot another thread on PCB support! O f all the topics, this one has been much repeated. T o each his own, i guess for brining up this

H eck, this topic is almost as repeated as stencil cleaning. E ngineers SHOULD be hands on, I agree. No argument there. R epeatability of any equipment or process is crucial for yield improvements. B ut sometimes, it takes a �number crunching type of guy� with an Engineering degree to

justify equipment, but at the same time, this guy should know equipment and processes, and obviously not be afraid to get the proverbial hands dirty. :-)

PS-what's wrong with being a hypochondriac??

chinee chooze... you from around here?

In my past life, I used a tooling plate by JNJ that is specifically made for MPM's. The theory is - it's an alphanumeric grid, like Battleship, where you figure out your setup once, and then document it. It worked with and fit nicely with the MPM HiE's vacuum H tower. Not sure if they still make it, but here's the Google results.
