Problems solved by technology

[0003] However, when the printed circuit board is baked, it will stretch due to thermal expansion. In the case where multiple parts on the surrounding edges are fixed and restricted, the printed circuit board will stretch along the stretch between the clamps. The length and width of the two directions are respectively deformed and arched, that is, the arched plate
In the case of multiple arches and the deformation directions of the arches are inconsistent with each other, it is easy to generate stress concentration on the printed circuit board, resulting in permanent deformation of the printed circuit board.

Abstract

The invention relates to an anti-arching circuit board rack, which comprises a rectangular rack body, two clamping tools and a buffer mechanism, the two clamping tools are respectively arranged on the corresponding side rods of the rectangular rack body and respectively clamp the left side edge and the right side edge of a circuit board from the left side and the right side, the buffer mechanism is elastically connected between one side rod and the corresponding clamping tool, and the buffer mechanism is elastically connected between the other side rod and the corresponding clamping tool. Therefore, the deformation quantity of the circuit board in the left-right direction is absorbed, and the arch plate of the circuit board is improved.

Description

Technical field [0001] The present invention relates to the field of circuit board frames, and more particularly to a circuit board shelf with a arched arch plate. Background technique [0002] The printed circuit board needs to be baked during the manufacturing process, and the printed circuit board to be baking will be disposed on the circuit board frame, and the printed circuit board is baked with a printed circuit board through a circuit board. A plurality of clamps are generally provided on the circuit board frame, respectively, respectively, a plurality of parts on the surround edge of the printed circuit board, to secure the printed circuit board, prevent the printed circuit board (especially the thin circuit board) in the bake process. It is contaminated between deformation or different circuit boards due to fluttering or different circuit boards. [0003] However, when the printed circuit board is baked due to thermal expansion, the plurality of parts on the surrounding ...
