Asking the Grid Lok to flatten out the board is like asking the SMT Reflow Furnace to detab the panel. It was not designed to make up for the deficiencies of your fab supplier or your unsuported 1st reflow pass on the the chain conveyor. However, i

Guy,s I do not have Red-e-set, but Grid-lok offers a fully automatic system that easily installs onto the printers and P&P. It can be set to your board instantly by pressing one button or triggered by the printer to set for each consecutive PCB. They

We worked with 3-4 revisions of the form-flex and they all had problems with stuck pins or pins that just wouldn't come out (due to leaks). The Form flex was pneumatic and hydraulic and worked well for awhile (2-3 weeks)but never seemed to last much

I agree, There seems to be quite a bit of negative impression regarding Grid Lok. We have 4 DEK printers outfitted with them. We have had a few problems that were due to warped boards but other than that, they have worked well for us. Fixed tooling

Maybe what you could do is have the stencil contain a tightly spaced mesh or grid of openings over the ground plane areas that you need to be solder covered. Also, to help the solder flow out better, you might want to decrease the percentage of metal

Hi there, I used Grid-Lok and some other PCB support from Quik-Tool (don't ask me model :) ), which is pretty similar to Grid-Lok, in Viscom machines. We also had jigs for high volume products similar to those you would use for PCB routing, but with
