Linda I know that you are signed on TechNet Could you please post question to all experts for me: We are reflowing 50pins CF card SMT connector and having high rate of the lifted leads (they are gull wings leads). We measured leads co planarity using CMM before reflow and it seems that all leads are meeting the spec. My guess is that the component body is bowing during reflow process (we are dong Pb free reflow with the peak of 234°C) causing lifted leads. Somebody told me that there is a lab who can measure leads co planarity during reflow cycle. Is anybody aware of such as test? Thank you Can anyone share some information, any help will be greatly appreciated.
