? Does this mean we should remove the ICs from their tape and reel packaging, tin the leads for proper gold removal, then re-reel the parts for proper packaging for pick and place equipment

) the requirements of the lead forming machine.Note that the leads must NEVER be bent by holding the body. They are always bent by clamping the lead and applying the bend on the non-body side of the clamp

vapor phase reflow soldering. The reason for such defects is usually caused by the fact that the thermal conductivity of the relevant component leads is too high, and the temperature rises too fast, which causes the upturn of the

. The primary advantage of 3D inspection over 2D inspection is that it provides true volumetric height information. Coplanarity on lifted leads and other height-sensitive devices can be detected without difficulty
