According to JESD22-B108 (complanarity test for SMD), the device's coplanarity defined as the largest distance distance between the contact point of leads and the established seating plane, but when the estabilished seating plane is estabilished by three leads which are bend downwards, Is it mean that all other device leads are out of planar position. So can I define it as vertical distance measured from the lowest lead? Thanks for your any input.
