Board-like connector, dual-arm bridge of board-like connector, and wafer testing assembly

A board-like connector for being sandwiched between two boards so as to allow the two boards are electrically coupled to each other by the board-like connector, the board-like connector comprising:

• a plurality of dual-arm bridges spaced apart from each other, wherein each of the dual-arm bridges includes:
• a carrier;
• a first cantilever and a second cantilever both extending from inner lateral walls of the carrier and both being coplanar with the carrier;
• a first abutting column extending from the first cantilever along a first direction;
• and
• a second abutting column extending from the second cantilever along a second direction that is opposite to the first direction;
• and
• an insulating layer connecting the carriers of the dual-arm bridges, wherein the first abutting column and the second abutting column of each of the dual-arm bridges respectively protrude from two opposite sides of the insulating layer;
• wherein the first abutting columns of the dual-arm bridges are configured to abut against one of the two boards, and the second abutting columns of the dual-arm bridges are configured to abut against another one of the two boards.
