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!

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

Can anyone tell me what type of material that the standard IPC SMT trays are made of ?? I am trying to mill some out however I need to order the correct ESD safe material ??

Does it have to be made out of plastic? Wouldn't some stock aluminum plate with milled out pockets work just as well? Would the aluminum offer the same, better, or worse ESD protection?

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

Thanks FCM, we remove the metal plate and make a new ferro-concrete base.Under foot put ESD rubber.Now machine working perfect - without any vibration. Thank you very much and success.
