I have seen a 15 deg to 30 deg 'bend' by scoring the board on one side only and folding the card towards the score line... till the desired degrees of bend were achieved... I think it was done on .032 material... with crossover traces on the farside of the score... - Bill Brooks -----Original Message----- From: Mark Tucker [mailto:[log in to unmask]] Sent: Friday, June 09, 2000 1:14 PM To: [log in to unmask] Subject: [TN] PWB minimum thickness and bend radius I have a design situation where I would like to do a one time "bend for assembly" to a small PWB. The board would be two sided, but would not have any components in the bend zone. The space I have for the bend is small. This leads me to four questions: What is the thinnest commonly used FR4? What is that materials minimum bend radius? What is the thinnest commonly used FR1? What is that materials minimum bend radius?
