The flexible circuit board is called FPC for short, FPC double-sided adhesive and a protective film are attached from FPC to FPCA through a Surface Mounting Technology (SMT), a plurality of mutually independent FPCAs are formed after cutting after splitting/board splitting operation, and the product and the protective film thereof are completely cut off in the splitting/board splitting operation mode adopted at present; the products and the protective films are all cut off, so that the follow-up production, taking, inspection, processing and other operations in the using process are inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving because burst/divide the board operation can all cut off the problem that causes operations such as taking, inspection, processing in inconvenient follow-up production, the use with product and protection film, the utility model provides a flexible line way board divides board mould can not all cut off product and protection film when carrying out burst/divide the board operation, divides the board after the product is cut off and the complete state of protection film, the operations such as taking, inspection, processing in convenient follow-up production, the use.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a flexible line way board mould, the mould includes knife face and base, the knife face is knife carving mould or etching mould, be provided with on the knife face and keep away the dead slot, flexible line way board holding in keep away the dead slot, the protection film does not cut off when mould divides the board, the complete state of protection film after the branch board.
Further, the difference in height of the blade points of the mold is 0.03 mm or less.
Furthermore, the material of the mould base is steel.
Furthermore, a positioning pin is arranged on the base, and the height of the positioning pin is 0.4 mm.
Furthermore, the levelness of the clearance groove is less than 0.03 mm.
Further, the blade point height difference of the knife face is the same as the levelness value of the clearance groove and smaller than the height value of the positioning pin, the protective film is not cut off when the die is used for splitting the plate, and the protective film is in a complete state after the die is split.

Detailed Description
As shown in fig. 1 to 4, a flexible circuit board splitting mold comprises a cutter surface 6 and a cutter base 8; four corners of the knife face 6 are provided with positioning pin holes 2 and positioning screw holes 3, the positioning screw holes 3 are positioned at the inner part of the knife face 6, and the positioning pin holes 2 are positioned at the outer part of the knife face 6; a mold positioning hole 4 and an empty avoiding groove 5 are formed in the middle of the cutter face 6, the mold positioning hole 4 is located on the periphery of the empty avoiding groove 5, flexible circuit board molds 12 are arranged on two sides of the empty avoiding groove 5, a positioning pin hole 1 is formed in the periphery of the empty avoiding groove 5, and the positioning pin hole 1 is located on the inner side of the mold positioning hole 4; four corners of the tool apron 8 are provided with positioning small holes 2 and positioning screw holes 3, the positioning screw holes 3 are located at positions close to the inside of the tool apron 8, and the positioning small holes 2 are located at positions close to the outside of the tool apron 8; a die positioning hole 4 and a positioning needle 7 are arranged in the middle of the tool apron 8, and the die positioning hole 4 is positioned around the positioning needle 7;
the positioning hole 2, the positioning screw hole 3 and the mold positioning hole 4 on the knife face 6 correspond to the positioning hole 2, the positioning screw hole 3 and the mold positioning hole 4 on the knife holder 8.
The height difference of the blade points of the blade surfaces 6 is 0.03 mm; the base 8 is made of steel; the height of the positioning pin 7 is 0.4 mm. The levelness of the clearance groove 5 is 0.03 mm.
One side of the flexible circuit board 9 is adhered with a double-sided adhesive tape 10, and the other side of the double-sided adhesive tape 10 is adhered with a protective film 11.
The height difference of the blade edge of the knife face 6 is the same as the levelness value of the clearance groove 5 and is smaller than the height value of the positioning pin 7.
According to location hole 2, location screw hole 3, mould locating hole 4 install the mould, knife face 6 is to gluing together flexible circuit board 9, double faced adhesive tape 10, protection film 11 carry out burst/board division operation, the bottommost protection film 11 is placed on base 8, because knife edge height difference of knife face 6 with keep away the levelness value of dead slot 5 the same, and be less than the height value of pilot pin 7, to when carrying out burst/board division operation flexible circuit board 9, double faced adhesive tape 10, protection film 11 will flexible circuit board 9, double faced adhesive tape 10 cut off, and protection film 11 is not cut and is in complete state (as shown in fig. 4).
