The invention provides a CCGA packaging device micro spring welding column rapid column planting clamp and method. According to the method, a micro spring welding column planting clamp, a vertical interconnection clamp and a bucket-shaped CCGA micro spring welding column storage tool are included. The micro-spring welding column implanting fixture can be used for quickly implanting the micro-spring welding column into the vertical interconnection fixture; the perpendicularity of the micro-spring welding column in the welding process is guaranteed through the vertical interconnection clamp; the bucket-shaped CCGA micro spring welding column storage tool ensures that micro springs are not in transverse contact in the column planting process. By means of the method, the problem that the micro-spring wire is wound in the column implanting process is solved, and the perpendicularity of the micro-spring welding column in the welding process is improved. The device is simple in structure, high ...
