Terminals are the most basic connection units in the vehicle’s electrical system. They are also key nodes in the wiring harness. The contact resistance, insertion and extraction force, corrosion resistance, and dimensional accuracy of a single terminal directly determine the stability of the vehicle’s signal and power transmission. These factors are also key to the
In the safety system of new energy lithium batteries, thermal runaway prevention is crucial. While cell materials and battery pack protection are well-known, the “safety trio”—OSD, Fuse, and rupture discs—on the square aluminum battery cover creates an immediate, vital barrier for the cell. Each device has a distinct role, and together they intercept risks like
New energy power and energy storage batteries contain a small but essential component: the sealing aluminum pins. Hidden in the electrolyte injection hole of the battery cover, this sealing pins is the main barrier for battery sealing, safety, and performance stability. It directly affects the battery’s lifespan and operational safety. What are Sealing Aluminum Pins?
Battery manufacturers face a key challenge with aluminum nails: prototypes meet standards, but in mass production, pressure resistance is unstable, welding leaks occur, production can’t keep up, rework costs rise, deliveries are late, and orders are lost. Despite their small size, battery sealing parts are key for battery safety, preventing leakage after laser-welding seals and
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
For battery manufacturers, the key challenge with sealing aluminum pins is that initial performance meets standards during prototyping, but issues arise during mass production—unstable pressure resistance, welding leakage, insufficient production capacity, costly rework, delayed delivery, and even lost orders. The small sealing aluminum pins on battery covers are crucial for safety. After electrolyte injection, laser-welds
Smart cars are rapidly evolving with more sensors, cockpit screens, and advanced autonomous driving features. However, this surge brings a connectivity challenge—high-speed data connections that remain a hidden headache for engineers. A Battle of Wits Between Space and Performance Picture this: Behind an overcrowded dashboard, wiring harness engineer Xiao Li must route 12 high-speed links
In modern society, the accuracy and dependability of medical devices are fundamental to patient safety. In this highly demanding industry, high-precision metal stamping parts hold critical importance. They serve as essential elements in medical devices and are pivotal in ensuring optimal performance. High precision metal stamping parts, recognized for their meticulous engineering, reliable operation, and
