smt on flexible board

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!

Large smt reel bin for machine placement on Mycronics line

Does anyone have a better way of holding large reels for the Mycronics machine? The arms are quite expensive so I currently use an ESD bin with a rod in the middle. It's kind of a pain when you need to change a reel. I saw a really cool bin, but the

My thoughts on metal trays: One problem with a metal tray relating to ESD is its conductivity. Most trays are conductive but have resistance or a disipative nature. If you were to place a "charged" component into a metal tray that had an uncontrol

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
