Okay, I tried searching the fine SMTnet Archives on this and I don't see anything newer than five years old, so I thought I'd try and get a modern take on the Grid Lok, Gel Flex, and Vacunest Board Support Systems. Who is using what, and do l You lik

Gel Flex works for Dek, just a slight modificaion. Works 100% better than any Grid type of system. We had missprints from Grid Lok and Form Flex - about every 5th or 6th board. Until we modified the Gels, we would take the time and some peelable s

It's cumbersome. Also if it catches a part partially after initial set-up, you'll get missprints. We had one and caused about 15% missprints. Once removed and hard pin in place, no missprints. Defeats vacuum board hold down too, from all of it's

Hmmmm.... We never had to change any parameters when switching over to Gels. And no, we don't let the operators have kitty-wampus on our programs either. The Gels did get rid of broken parts. We have Run Orders of about 50 pieces. We change over

I beta tested these 6 months before general availability. These devices worked well in some situations and mrginally in others. Migrating to Gel may depend on what your current issues are with your current tooling solutions. Generally speaking it w

The only easy solution is not to handle the boards. Purchase true double sided reflow lines. Buy automated magazine loading conveyors. Check machine board supposrts. Are you sure it's from handling? We found it was 50/50 between board handling

I would definately try to sell the bosses on the Grid-lok over the gel piggies. We evaluated both and wound up buying the Gel (for close to the same money). On an MPM if you put enough gel packs in the vacuum box (to support the board) it holds the b

Dedicated tooling uses what MPM calls an "H" tower. You mount the board support plate (dedicated tooling) on top of the H tower. If boards are only single-sided SMT, meaning only components on one side, the board support plate is flat with vacuum hol
