Is there anyone who knows the yield rate difference for SMT on multi-flex boards and rig-flex boards ? Basically, I think the yield rate should be higher for rig-flex than multi-flex due to the poor dimensional stability of polyimide, since multi-fle

Dear Chris Thank you so much for the prompt reply and it really helps. Do you have any SMT experience for rig-flex boards? Can you share with me about the differences with that of rigid boards? Is there any special precaution needed? When you were d

Hi Christina, What would you be basing the yields off of? Is it solder defect, component placement, etc....? I have worked for a flex house for quite a few years. You are right. The Polyimide is very dimentionally unstable. (even more so on humid da
