The COC fishbone fixtures in Burn-in System, with its fishbone array-like design, integrates positioning slots, beryllium copper elastic contact springs, and thermally conductive trenches. It is a key high-value consumable in the production and testing of optical modules, primarily used for burn-in tests of optical chips. Its core function is to provide precise positioning, stable
Let me draw you a picture. You’ve just finished a run of high-power laser diodes. You send them to burn-inin testing — 24 hours at 85°C with a constant current — and when they come out, half of them have degraded. Not because the chips are bad, but because your socket killed them. Poor contact.
Engineers performing chip aging tests know one thing: No matter how well designed the burn-in board is or how precise the temperature control is, a malfunctioning aging test fixture ruins the entire experiment. Intermittent contact problems, probe shrinkage at high temperatures, and chip cracking from cap deformation are common in mass production aging. Most issues
In the semiconductor industry, it’s said: “A chip untested for aging can’t be trusted for vehicle use.” This refers to chip burn-in testing. The tool used is the chip burn-in test fixture, commonly called a burn-in socket. Many associate it with simply “a socket holding a chip at high temperature,” but engineers experienced in mass
Chip Packaging and Testing: A Key Link in the Semiconductor Industry Within the expansive semiconductor industry, chip packaging and testing are critical technical processes. Chip packaging and testing, also referred to as assembly and test, entails enclosing chips produced by wafer fabrication and subjecting them to rigorous performance evaluation, turning them into finished chips ready
Packaging and testing are the final steps in the chip manufacturing process. Packaging is responsible for protecting, securing, and electrically connecting the bare chips diced from the wafer, enabling them to communicate with external circuits. Testing, on the other hand, uses a series of electrical performance tests to screen out qualified chips, ensuring the reliability
