Research & Development

Yezhan Electronics has cutting - edge R & D capabilities, with 20 - million - yuan worth of equipment. It meets diverse inspection needs for alloy resistor products from microscopic to macroscopic.

7 - year raw material system research

Passive components' performance depends on material science. Yezhan Electronics' tech approach is based on alloy raw material processing.
An R & D team of materials science postdocs and grad students updates smelting formulas, adjusting trace element ratios to meet industry needs.

12 - year research on heat treatment wire drawing & rolling process

Hot silver treatment, cold rolling, and heat treatment achieve alloy material pre - treatment, ensuring excellent consistency, stability, and controllable TCR.
Yezhen can offer ultra - low TCR solutions for most products compared to industry standards.

15 - year research on welding technology

Automatic fluorine arc welding tech (Patent No.: ZL202120857626.X) enables 100+ HSR series specs, replacing British TT's OAR series products.
Automatic resistance welding tech (Patent No.: ZL202020620880.3) enables 100 - spec JSR series production, auto test & adjust, cuts costs, increases production.
The automatic laser welding tech (Patent No.: ZL201820907052.0) pioneered welding 0.1 - 0.4mm thick copper strips.
Yezhan used auto electron beam welding tech to expand thickness from 1 - 4mm to 0.3 - 4mm after 10+ years of tech & process accumulation.
Welding tech breakthroughs enabled resistors to cover all sizes, achieve international brand substitution domestically.
