Every wiring harness in a modern vehicle depends on connector terminals that mate perfectly, every single time. Inconsistent insertion force, poor plating adhesion, or dimensional drift across a production run can lead to intermittent electrical faults — a risk no automotive engineering team is willing to accept. HEJU Stamping-a automotive connector terminal manufacturer China, who
The group standard titled “Technical Specifications for High-Voltage Connector Terminals for New Energy Vehicles” (Standard No.: T/CASME 2161-2026)—proposed and administered by the China Association of Small and Medium Commercial Enterprises, with Heju Precision participating in its drafting—has been officially released and implemented following public notice on the National Group Standard Information Platform. This marks another
Recently, Heju Precision officially launched its new ERP management system. This move marks a new stage of standardization and integration for Heju Precision. Digitalization and lean manufacturing are key paths for precision metal stamping companies to reduce costs and increase efficiency. As the company’s business continues to grow, the drawbacks of traditional management models, such
Dongguan City recently announced the 2026 list of “Doubling Enterprises.” Dongguan Heju Precision Electronics Technology Co., Ltd. was selected for its business strength, innovation capabilities, and steady growth momentum. What is a “Doubling Enterprise”? Since its launch nationwide in 2017, Dongguan City’s “Doubling Plan” has become a key long-term initiative to promote high-quality manufacturing development
If you’re still using conventional contactors for COC (Chip‑on‑Carrier) burn‑in, this artical will tell you why fishbone fixtures in CoC burn‑in systems are necessity for any reliability lab. What Exactly Is a COC Burn-in System, and Why Is It So Demanding? Before we dive into the fixture, let’s set the stage. A COC is a
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.
Metal stamping springback is a difficult problem for the automotive stamping parts.There is not a perfect method to deal with springback of stamping parts.After researching the stamping springback problem,we get following factors: Material Performance There are different strengths of automobile stamping parts. from ordinary plate to high strength plate, different plates have different yield strength.
Repeatedly plugging and unplugging the charging connector subjects the electric vehicle charging terminals to mechanical friction, arc erosion, and oxidation/corrosion, which easily leads to performance deterioration and unstable charging. To address these rigorous operating conditions, the national standard GB/T 20234.1-2023 explicitly mandates a mating durability of 10,000 cycles for charging connectors, establishing a fundamental quality
