Hi, how to ensure flexible boards do not warp after reflow and still remain flat for subsequent operations. What is the best way to hold and transport these strips from one process to another. Thanks!

Ron, The simplest way to process fexible PCB's that I have found is to use a process carrier fixture. There are companies that manufacture process carriers that are capable of holding flex through stencil, placement and reflow. The carriers are capab

Ron: Chris is correct that there is a bunch of fixture fabricators that make good products that will serve your purpose. Other fixture fabricators can be found in the archives. Problems with these fixtures are: 1 Out-rageously expensive 2 Very lo

If your flex circuit is only populated on one side, you can have the PCB vendor palletize the flex for you. What you do is have the flex circuit laminated to 062" FR4 using a thermoset adhesive like Dupont WA. Standard flex circuit adhesive. Howev

Ask for board fiducials if you're running arrays. Global fids on the panel do not work well. One handy product we use on flex is "Tacsil". Works well on SMT pallets as well as router operation. It's double sticky stuff that helps hold on to the P

I had a PDR Lightmaster Pro at the last place I worked at, and I thought it was the best rework station I've ever used. Not only because of the fact that no nozzles were needed, but the heat delivery from the focused IR light was superb. I don't know

One of our divisions is having this problem: - De-wetting on the smt pads and componenent termination on the bottom side after top side procssed through reflow. Board finish is immersion silver. ? Any recommendation on what we should check & verify
