Abstract
Because the mechanical strength of the flexible circuit board is low, in order to strengthen the mechanical strength of the flexible circuit board, the components are convenient to be inserted and installed, and reinforcing materials are usually required to be attached to the surface of the flexible circuit board. In order to match with the automatic suction and sticking of PI (polyimide) reinforcement, the PI reinforcement needs to be cut into single pieces, and meanwhile, in order to improve the suction and sticking efficiency, two pieces of PI reinforcement are usually combined into one piece, and redundant parts are cut off after the two pieces of PI reinforcement are stuck. The existing PI reinforcement has an inner hole after being combined, and the PI reinforcement with the inner hole design needs to use a steel cutter die to punch the inner hole, so that the cost of the die is higher, and the production cost is increased. The utility model provides a pair of novel PI reinforcement structure does not have the hole, including laminating portion and connecting portion, the one end of laminating portion is passed through connecting portion and is connected, uses the etching cutting die can the shaping, and the mould is with low costs, but reduction in production cost.
Description
Technical Field
The utility model relates to a flexible line way board makes the field, especially relates to a novel PI reinforcement structure.
Background
Because the mechanical strength of the flexible circuit board is low, in order to strengthen the mechanical strength of the flexible circuit board, the components are convenient to be inserted and installed, and reinforcing materials are usually required to be attached to the surface of the flexible circuit board. In order to match with the automatic suction and sticking of PI (polyimide) reinforcement, the PI reinforcement needs to be cut into single pieces, and meanwhile, in order to improve the suction and sticking efficiency, two pieces of PI reinforcement are usually combined into one piece, and redundant parts are cut off after the two pieces of PI reinforcement are stuck.
The existing PI reinforcement has an inner hole after being combined, and the PI reinforcement with the inner hole design needs to use a steel cutter die to punch the inner hole, so that the cost of the die is higher, and the production cost is increased.
SUMMERY OF THE UTILITY MODEL
For solving the not enough of above prior art, the utility model provides a novel PI reinforcement structure, including laminating portion and connecting portion, the one end of laminating portion is passed through connecting portion and is connected.
Preferably, the number of the attaching portions is at least 2.
Preferably, the length of the connecting portion is equal to the distance between the FPC attachment portions.
Preferably, the number of the connecting portions is 1 less than the number of the bonding portions.
Compared with the prior art, the utility model has the advantages of it is following:
the existing PI reinforcement has an inner hole after combination, a steel cutting die is needed to punch the inner hole during molding, and the die cost is high; the utility model provides a pair of novel PI reinforcement structure does not have the hole, uses the etching cutting die can the shaping, and the mould is with low costs, but reduction in production cost.
