Description

Technical Field

[0001] This utility model relates to the field of PCB board testing technology, specifically a PCB board compression testing machine. Background Technology

[0002] A PCB compressive strength tester is a professional device used to test the compressive strength of printed circuit boards. It is mainly used to detect the performance of PCB boards when subjected to vertical pressure, including the limit of pressure they can withstand, the deformation under pressure, and whether defects such as cracking or delamination occur. This allows for the evaluation of the quality and reliability of the PCB board. By applying gradually increasing pressure to the PCB board, it simulates the squeezing and collision situations that it may encounter in actual use. Pressure sensors and data acquisition systems record data such as pressure values ​​and corresponding deformation amounts, providing a basis for analyzing the compressive strength of the PCB board.

[0003] Different types and sizes of PCBs require corresponding fixtures for fixation. However, the fixtures may not be fully compatible with all PCBs. If the fixtures are poorly designed or improperly installed, the PCBs will be subjected to uneven force when under pressure, which will affect the accuracy of the test results and may even damage the PCBs. To address this, we have proposed a PCB compression testing machine. Utility Model Content

If the clamp design is unreasonable or the installation is improper, it will lead to uneven stress on the PCB board when it is compressed, thereby affecting the accuracy of the test results and even potentially damaging the PCB board. To achieve the above objective, this utility model provides the following technical solution: a PCB board compression testing machine, including a fixed platform, wherein a sliding component is provided on the top of the fixed platform;

Operators can quickly install different types of PCB boards on the testing machine for pressure testing, significantly shortening preparation time before testing, improving overall testing efficiency, and allowing continuous testing of multiple different types of PCB boards without frequent fixture changes or adjustments. This reduces equipment downtime, makes testing smoother, and further improves work efficiency.
