Abstract
The utility model discloses a kind of PCB preventing being out of shape, comprise circuit board body, described circuit board body is provided with circuit, the non-routing region place of circuit board body is provided with Copper Foil, the back side of wiring board body is equipped with two-layer Copper Foil, is stained with one deck resistance to deformation glue between two-layer Copper Foil; Described resistance to deformation glue is new polyurethane PUR.The utility model, by two-layer Copper Foil and one deck resistance to deformation glue, achieves the three-layer protection to wiring board, effectively prevent the distortion of circuit board.
Description
Technical field
The utility model relates to art of printed circuit boards, is more particularly a kind of PCB preventing being out of shape.
Background technology
PCB(Printed Circuit Board), Chinese is printed wiring board, and being called for short printed board, is one of vitals of electronics industry.Almost often kind of electronic equipment, little of electronic watch, calculator, arrive computer greatly, communication electronic device, military issue weapons system, as long as there are the electronic devices and components such as integrated circuit, in order to the electric interconnection between them, all will use printed board.Along with the development of field of circuit boards, ultrathin circuit board is more and more welcome, but ultrathin circuit board ubiquity holds yielding problem.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provides a kind of PCB preventing being out of shape.
The purpose of this utility model is achieved through the following technical solutions:
A kind of PCB preventing being out of shape, comprise circuit board body, it is characterized in that: described circuit board body is provided with circuit, the non-routing region place of circuit board body is provided with Copper Foil, the back side of wiring board body is equipped with two-layer Copper Foil, is stained with one deck resistance to deformation glue between two-layer Copper Foil.
Described a kind of PCB preventing being out of shape, is characterized in that: described resistance to deformation glue is new polyurethane PUR.
The utility model has the advantage of:
The utility model, by two-layer Copper Foil and one deck resistance to deformation glue, achieves the three-layer protection to wiring board, effectively prevent the distortion of circuit board.
