Patent ID: 8251712

Claim:
A printed circuit board (PCB) module, comprising: a first rigid PCB comprising a plurality of first connecting contacts; a second rigid PCB comprising a plurality of second connecting contacts, the second connecting contacts spatially corresponding to the first connecting contacts; and a connecting mechanism comprising: a flexible connecting board positioned between the first and the second rigid PCBs, the flexible connecting board comprising a plurality of connecting circuit traces isolated from each other, the flexible connecting board comprising a first connecting portion, a bent portion, a second connecting portion, and a coverlay covering the connecting circuit traces at the bent portion, the flexible connecting board being bent in such a manner that the first connecting portion is in contact with the first connecting contacts, the second connecting portion is in contact with the second connecting contacts, and each of the first connecting contacts is electrically connected to a corresponding second connecting contact via the corresponding connecting circuit trace; an elastic member compressed between the first and the second connecting portions; and a fixing member configured to fix the first and the second rigid PCBs together and compress the elastic member.
