How many cycles will it have to survive in its lifetime? ______________________________ Reply Separator _________________________________ Subject: Kapton Author: [log in to unmask] at Internet Date: 4/22/97 8:28 PM Hello friends, I have a question about the material Kapton. Does this material deteriorate due to flexing (if used in a PC board). I want to use it to wrap around a hinge on a small door that will need to close (where the board will bend 180 degrees) and be able to open (where the board will bend about 90 degrees). So the board will need to bend repeatedly between 90-180 degrees. Will this hurt the board? Second, can you just put a crease in the board and end up with the board in an accordian like shape that would relieve the stress of the opening and shutting? Does this compromise the integrity of the board and the wiring? If anyone has any experience in this, I would appreciate some suggestions. Also if you knew of a better technique or material, I would be happy to hear them. Thanks a lot.
