[0002] A circuit board press is a device that can realize high-temperature circuit board pressing. The working principle of the circuit board press is to place the circuit board between two hot plates, heat the heating element to soften the circuit board locally, and deform or replicate the desired shape under sufficient pressure to complete the manufacturing process. Circuit board presses are generally suitable for single-sided, double-sided and multi-layer circuit boards, and some models are used for the manufacture of high-density boards and rigid-flexible boards. The following problems exist in the existing technology:

[0003] During the high temperature and high pressure lamination process, circuit boards are prone to deformation, especially thin boards. Deformation can cause electronic components on the circuit board to shift or break, and even affect the function and reliability of the entire circuit board.

[0004] In order to solve the problems of deformation, looseness and uneven processing during the pressing process of high-temperature circuit boards, a tooling fixture for press-fitting high-temperature circuit boards is proposed. Utility Model Content

A circuit board is clamped and connected between the top hinge mechanism and the bottom hinge mechanism, and the top hinge mechanism comprises a top thin plate; the side clamping mechanism comprises a track; and the bottom hinge mechanism comprises a bottom thin plate.

[0007] A further improvement of the technical solution of the utility model is that a bottom metal plate is fixedly installed at the bottom of the metal frame, and a top metal plate is fixedly installed at the top of the metal frame.

[0010] A further improvement of the technical solution of the utility model is that the bottom of the top magnet clamps and adsorbs the circuit board.

[0011] A further improvement of the technical solution of the utility model is that: a tooth groove is provided on the inner wall of the track, a clamping groove is provided in the middle of the track, and a positioning groove is provided on one side of the bottom of the track.

[0012] A further improvement of the technical solution of the utility model is that a top hinge mechanism is inserted into the upper limit position of the track.

[0013] A further improvement of the technical solution of the utility model is that: a bottom hinge is fixedly installed on the inner wall of the bottom thin plate, a bottom magnet is movably installed on the inner wall of the bottom thin plate through the bottom hinge, and the top of the bottom magnet is magnetically connected to the circuit board.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

The side clamping mechanism is located at both ends of the metal frame, and the track is provided with a tooth groove, a card slot in the middle, and a positioning slot on one side of the bottom. The side clamping mechanism provides clamping force through the tooth groove and the card slot to ensure that the circuit board will not move or loosen during the pressing process.
