Burn-in Pogo Pin

Burn-in Pogo Pins are specialized spring-loaded connectors designed to withstand the rigorous conditions of burn-in testing, a process that subjects electronic components to elevated temperatures and voltages to identify early failures. These pins play a critical role in maintaining reliable electrical contact between the device under test (DUT) and the burn-in board, ensuring consistent performance throughout the stress-testing period.

Constructed from high-grade materials such as beryllium copper or stainless steel, Burn-in Pogo Pins offer exceptional thermal stability and corrosion resistance, essential for enduring temperatures ranging from 85°C to 150°C—common in burn-in chambers. The spring mechanism, often made from heat-resistant alloys, maintains constant contact force even as materials expand or contract under thermal stress, preventing intermittent connections that could invalidate test results.

The tip of a Burn-in Pogo Pin is engineered for durability, with plating options like gold or nickel to minimize oxidation and ensure low contact resistance. This design feature is crucial because high resistance can generate unwanted heat, affecting both the pin’s performance and the accuracy of the burn-in test. Additionally, these pins are designed to handle higher current loads, up to several amps, to simulate the power conditions components will encounter in real-world operation.

Burn-in Pogo Pins are available in various configurations, including different lengths and tip styles (e.g., chisel, dome, or needle), to accommodate diverse DUT pad sizes and layouts. They are often integrated into custom burn-in fixtures, where their modular design allows for easy replacement after prolonged use—an important consideration given the high cycle counts of burn-in testing. By ensuring reliable, low-resistance connections under extreme conditions, Burn-in Pogo Pins help manufacturers screen out defective components, improving the overall quality and reliability of electronic products.
