Abstract:
This invention discloses s a double sided insert board, on which one side is provided with at least one front board connectors according to the notch width, the other side is provided with at least one back board connectors according to the notch width. The front board connectors and the back board connectors are located at the same level on the double sided insert board as well as are staggerd about. The front board connectors and the back board connectors are the uniform board connectors of same standard and with same pins. The double sided insert board according to the invention satisfy the common usage of the front board and the back board. The invention also has no special demands to the design, production, and manufacture of the boards, which reduces the production cost and difficulties in project. As the same time, the front board and the back board are same, which reduces the cost for design.
