Bow and Twist of PCB's

Electronics Forum | Wed Aug 19 05:00:56 EDT 1998 | Tom Blum

Hi there, I'm actually facing a lot of trouble with PCB's presenting up to 3mm of bow /twist at reception i.e. before assembly. The PCB size is 220 by 230mm. The boards are to be assembeled SMD double sides with 05.mm pitch on both sides. In order to

If you study how the process is done now, it isn't that different from what you describe. Instead of glue, we use solder paste, and instead of spraying it we screen print it. But not that different. For feeding boards we use conveyors instead of rubb

The problem about covering it with glue (without using solder) is that the components might dislodge by a miniscule amount underneath the glue. So maybe the contact points will disconnect. I'm not sure if this will be a real problem, but if so it wo
