Description

Technical Field

[0001] This utility model relates to the field of headphone circuit motherboard technology, and in particular to a headphone circuit motherboard soldering fixture. Background Technology

[0002] The headphone circuit board soldering fixture is a device used to fix and position the headphone circuit board to ensure that the circuit board is accurately positioned during the soldering process. The fixture is designed so that the circuit board can be firmly clamped on the clamp for soldering operations. Using the soldering fixture can simplify the operation, improve soldering efficiency and quality, reduce manual operation, and ensure the stability and consistency of the soldering process.

[0003] During use, the headphone circuit board soldering fixture is used by workers to place the headphone circuit board in the working position and use clamps to hold and fix the headphone circuit board on both sides to achieve the purpose of fixing the headphone circuit board. However, traditional clamps are prone to misalignment of the headphone circuit board when holding it, which can cause the clamps to misalign afterward. In addition, the circuit board is prone to left and right displacement due to vibration or accidental contact during the soldering process, which affects the subsequent soldering work.
