My first reaction would be to run! FAST! Flex -- well, it... flexes... and isn't flat. While you assemble it, While you transport it, While it goes through the oven... SMT Connectors typically need to be held down during reflow. Fiducial types are

| | | Hello everyone, | | | We found many cylindrical diodes missing during SMT process. Could someone tell us how to prevent this problem? Is it effective to change the shape of stencil apture or reduce fan speed in reflow oven? Thanks in advance. |
