The invention discloses a conductive core plate and a manufacturing method. The conductive core plate comprises an insulating material layer, a
metal conductive circuit layer, a packaging
adhesive film layer and a back plate layer in sequence from top to bottom, wherein all the
layers are bonded in a low-temperature heating mode; the
metal conductive circuit layer and the packaging
adhesive film layer are compounded and bonded, and a conductive
circuit diagram is arranged on the
metal conductive circuit layer; a plurality of small holes are formed in the insulating material layer, and the positions of the holes correspond to the positions of
electrode points on the battery piece; the conductive
circuit diagram takes set unit patterns as a basis, and the unit patterns are arranged above thebattery piece in an array manner. According to the invention, the conductive core plate adopts a longitudinal cardinal number column 13*12 half-
cut battery arrangement mode, and the cardinal number column battery arrangement is achieved; meanwhile, the number of the batteries connected with the diodes is equal, the installation direction of a
junction box is parallel to the short edges of the
assembly and is the same as the position of a
junction box of a conventional
assembly, and if the connection mode is a solder strip
assembly, the connection mode is hardly achieved, and the equipment transformation cost can be effectively reduced at the same time.
