How to choose a Test Probe suitable for Test Fixture?
Choosing a test probe is like selecting a capable assistant for your test fixture. If you choose the right one, testing will be fast and accurate; Wrong choice, there are a bunch of problems! Firstly, the electrical performance must be reliable, and the impedance must match the signal, otherwise the signal will be distorted. The current carrying also needs to be strong enough, don’t overheat and strike immediately after testing. High frequency testing also requires selecting test probe with low noise and low loss for stable signal transmission.
Secondly, the mechanical performance should not pull the hips, and the contact force should be just right. Too light for poor contact, too serious for testing points. Durability also needs to be strong, it can contact >100,000 times without breaking, which is worry free and cost-effective.
Moreover, environmental adaptability is crucial, as it must withstand high or low temperatures, corrosion, humidity. In automotive electronics or industrial environments, test probe must be of a tough guy grade. Finally, compatibility and cost-effectiveness also need to be considered. The test probe needs to be adapted to your testing point and cannot be too expensive, after all, saving money is also a hard principle! Choosing the right test probe, the testing efficiency will take off directly!

How to choose a suitable test probe for test fixture?
Electrical performance: the key to testing accuracy
Electrical performance of test probe directly affects the transmission quality and accuracy of test signal. In order to ensure test signal is not distorted, test probe impedance must match the impedance of the circuit being tested. If the impedance can’t match with each, it’ll cause signal reflection, which in turn affects test results. Low contact resistance ensures stable current between test probe and circuit board, which is crucial for high-precision testing. The frequency response of test probe needs to cover your application requirements. If test signal frequency is high, you need to choose spring loaded probe that can support high-speed signals.
Mechanical properties: durability and precise contact
A good test probe has excellent mechanical strength, which directly affects durability and long-term effectiveness of test probe. Common test probe materials include stainless steel and beryllium copper alloy. Choosing materials that are wear & corrosion-resistant can effectively extend test probe lifespan. Elastic design of test probe directly affects its contact effect with test point. A hard test probe may cause damage to the circuit, while a too soft test probe may lead to poor contact. Frequent testing may lead to wear of test probe, so it is necessary to choose wear-resistant materials to avoid testing errors caused by probe wear.

Environmental adaptability: Adapt to various working conditions
Test probe often needs to work in high humidity, high or low temperature, complex working environments. Working temperature range of test probe needs to meet testing environment. In high temperature, it is necessary to select testing probe with high temperature tolerance. If humid or prone to dust accumulation, choose a testing probe with good sealing performance. This can effectively prevent liquid, moisture and dust from affecting test results. If there may be corrosive substances in testing environment, choose gold plating or stainless steel with strong corrosion resistance. This can effectively extend test probe lifespan.
Compatibility: Seamless connection with testing fixture
Compatibility determines whether test probe can use smoothly with various testing devices. If test probe isn’t compatible with target device, it may result in test failure or inability to obtain accurate test data. Different testing equipment may require BNC,SMB, or pogo pin. When selecting, ensure test probe interface is compatible with the device. The size of the test probe needs to match circuit size of UUT. A test probe is too large to reach precise test points, while a probe that is too small to be unstable. Some test probes adopt modular design, supporting the replacement of different probes and accessories. This design enables test probe to be used in various testing scenarios, increasing its versatility.

How to maximize the performance of Test Probe in Test Fixture?
Choosing the right test probe material
A high quality beryllium copper or stainless steel will directly improve the contact performance and durability of test probe. johoty typically uses a high quality gold or gold plating, which significantly improves the stability of the contact and the speed of the signal transfer. When selecting a material, we often consider the current carrying capacity, oxidation resistance and stability of the contact with the surface being tested. The right material extends the service life of test probe and also improves the accuracy of the measurement.
Optimizing contact pressure
The amount of pressure at which test probe comes into contact with the object under test is critical. Too much contact pressure can damage the UUT and may leave scratches on the surface of the DUT. Too little contact pressure will result in poor signal contact and affect the measurement results. Therefore, adjusting the contact pressure to ensure that it is within the optimal range is one of the keys to improving the performance of test probe. It’s critical to maintain high stability of test fixture. In order to obtain the optimum pressure, a test probe with a pressure regulator can be selected.
Precise selection of test probe design
Different testing purposes require different types of test probes; for high frequency signal testing, choose a test probe with low inductance and high frequency response; for high current testing, choose a test probe that can carry high current and has a large contact area; and according to the testing requirements, choose the appropriate test probe design, which is very critical.
