Hi John, We use Spray mount adhesive on durastone pallets, then kapton tape on the egdes. We have produced upto 25K flexi PCB's a day with this method. The trick is to get just the right amount on the pallet, to maintain tackiness. Cheers, Rob.

Over time, you might see problems with delam., blistering and warpage if using FR4 carriers. Depending on volumes, you might consider using durostone or some robust material like that for the production runs. Keep in mind that switching materials w

We've talked about assembling on flex previously. Search the fine SMTnet Archives for background. Issues that come to mind [which is very risky, given that this Saturday morning and last night was at Jimbo's] are: * Use carriers that can flow thoug

If you are talking about "low" volume another option you could consider is using a waffle tray. At a previous company we made low volume high value flexi-rigids. Like you, no-one would buy volume on reels. Luckily we had our own machine shop and we m

Hi folks, thanks for all the tips. We have run our first batch of these flexi boards now. I had the PCB suppliers make me some 1.6mm FR4 carriers to lay the boards on to carry them through the process. (1 flat & 1 with cutouts for the second side)

We have been processing a 3 and 5 up flex array for nearly four years on pallets and have had a pretty steep learning curve. Make sure you have vacuum holes in your pallet for the screen printing process, also work with your support block vendor to
