FLEXIBLE REWORK DEVICE

摘要

A rework device in form of a flexible circuit is provided in order to repair a printed circuit assembly. The printed circuit assembly includes one or more through vias and interconnections. The flexible circuit includes a lead in portion and a tail portion. The flexible circuit also includes a first distended head portion proximal to the lead in portion and a second distended head portion proximal to the tail portion. Further, the second distended head portion is connected to the first distended head portion through a coverlay portion. The flexible circuit provided is adapted to be threaded through a through via to repair the printed circuit assembly.

主权项

1. A design and rework device for use in creating in or thru via and repair of a printed circuit assembly, the printed circuit assembly having at least one through via, the design and rework device being in form of a planar flexible circuit configured to be threaded through the at least one through via, the planar flexible circuit comprising:
at least one lead-in portion at one end of the planar flexible circuit; at least one tail portion configured to align the planar flexible circuit on a surface of the printed circuit assembly; at least one first distended head portion proximal to the lead-in portion; and at least one second distended head portion proximal to the tail portion, the at least one second distended head portion being connected to the at least one first distended head portion by at least one flex portion, wherein a length of the at least one flex portion is substantially equal to a depth of the at least one through via.
