From the current market trend, the internal space integration of 3C electronic products is high, and the pitch is constantly shrinking. The small-pitch pogopin probe module has poor adaptability in this field and can only handle pitches ranging from 0.3mm to 0.4mm. Its lifespan and stability are poor. The 3C lithium battery testing requires a large current, and the rated current that the pogopin probe module can bear is only 1A. During the transmission process, the current will attenuate at different bits, resulting in unstable connections.

Regardless of small pitches or large currents, the large-current spring-clip micro-pinch module has perfect solutions. In this field, the large-current spring-clip micro-pinch module is preferable. The pitch value is 0.15mm - 0.4mm, with stable and reliable performance. Facing the requirements of large-current testing, the large-current spring-clip micro-pinch module can withstand a rated current of 50A. With a resistance of 1 - 50A remaining constant and almost no current attenuation, it has good connection function and can maximize the stability of 3C lithium battery testing.

In terms of lifespan, the test lifespan of pogopin probe module is 5W for large-current spring-clip micro-pinch module, which is approximately 4 times longer than that of pogopin probe module. The pogopin probe module has a multi-component structure, complex production process, high production difficulty, and long delivery cycle; while the large-current spring-clip micro-pinch module has an integrated spring-clip structure, light and flat, and can be customized according to customer requirements. The production difficulty is low, and the delivery cycle is short. In contrast, the cost-performance of the large-current spring-clip micro-pinch module is not very high!

Comparing the test pass rate of the mother seat, pogopin probe module is almost impossible to achieve for BTB connector mother seats, and the stability is extremely poor. Most adopt the touch solution, and the test pass rate of the mother seat is less than 80%; there is a special large-current spring-clip micro-pinch module corresponding method on the mother seat. Insert the oblique-mouth type (also known as the pointed-head type) spring-clip head into the connector end terminal to maintain a certain opening degree, so as to ensure the contact surface of the spring-clip and the contact surface of the BTB connector terminal on both sides remain in contact, making the test stable, and the test pass rate of the mother seat reaches 99.8% (some products can reach).

The large-current spring-clip micro-pinch module has high testing efficiency and good stability. Compared with the same product before and after testing, the connector basically shows no scratches and does not cause any damage to the product. The pogopin probe battery testing module is more worthy of selection and trust.
