What shapes do test probes have?

2024-02-24 13:53:49

A test probe is a tool used to test electronic components or circuit boards. They are usually made of metal and come in different shapes and sizes. In the electronics manufacturing industry, test probes are widely used to test the connectivity and functionality of circuit boards to ensure product quality and performance. So, what shapes do test probes come in? Let’s introduce it in detail below.

First, the most common test probe shape is needle-shaped. Test probes of this shape are usually used to test small components or connection points on circuit boards, such as resistors, capacitors, transistors, etc. Needle-shaped test probes typically have sharp tips that can be easily inserted into small holes or connection points on circuit boards to ensure a stable electrical connection.


Secondly, another common test probe shape is spherical. Spherical test probes are usually used to test large components or connection points on circuit boards, such as integrated circuit chips, sockets, etc. Spherical test probes have rounded tips that provide a wider contact area, ensuring a more stable electrical connection.

In addition to needle-shaped and spherical shapes, there are also some other shapes of test probes, such as flat-headed, tapered, double-headed, etc. These shaped test probes are often used for special testing needs, such as testing components of different shapes or sizes, connection points, etc. Test probes of different shapes can provide different contact methods and contact areas to meet different testing needs.


In general, test probes come in a variety of shapes, and each shape has its specific application scenarios and advantages.

By selecting the appropriate test probe shape, the accuracy and reliability of the test can be ensured, and the quality and performance of the product can be improved. I hope the above introduction can help everyone better understand the shape of test probes and their applications.
