Ultra-precision straightening of hard disk read-write heads - cloud computing storage devices

Ultra-precision straightening of hard disk read-write heads - cloud computing storage devices

The read-write head (E-block) of the cloud computing server hard disk is made of 0.3mm ultra-thin stainless steel, and micrometer-level deformation will lead to data read and write failure. The hydraulic press is equipped with a laser micrometer for closed-loop straightening: the deformation is detected by a 0.5μm resolution sensor, and the pressure is applied in 3 stages with a progressive pressure of 5-20kN, correcting the 0.005mm level bending to a tolerance range of ±0.001mm within 3 seconds. This technology is applied to Seagate's Enterprise-level hard disk production line, reducing the failure rate by 70%.

Server heat sink module bonding - Data center hardware production

High-performance computing servers require high-density heat sink fins. Using a hydraulic press with controllable pressure of 150-300 tons, 0.1mm thick copper fins are solid-state diffusion welded to copper heat pipes: precise pressure is applied for 120 seconds in a 400℃ vacuum environment, allowing the interfacial metal atoms to interpenetrate, increasing thermal conductivity by 30% (to over 400W/mK). This process solves the problem of micropores on the contact surface of GPU/CPU heat sinks, ensuring 7x24 stable operation of data center equipment.
