Industrial background and GiantOhm microelectronics manufacturing complex

Ningbo GiantOhm Micro Electronics Technology Co., Ltd. was established in March 2021 within the Hangzhou Bay industrial cluster in Ningbo, Zhejiang province.

Backed by prominent industrial technology investors including Xiaomi and Inovance, the enterprise established an advanced full-cycle research and production facility dedicated to passive electronic components.

The manufacturing facility incorporates automated high-precision equipment with error-proofing controls.

Independent dedicated lines operate for automotive components under IATF 16949 quality management requirements and ISO 14001 environmental frameworks, guaranteeing process consistency and reliability across mass production runs.

Thick film chip resistors: architecture, dielectric materials, and families

GiantOhm thick film chip resistors are fabricated via precision screen printing of ruthenium oxide resistive paste onto high-purity aluminum oxide Al2O3 ceramic substrates.

Following high-temperature firing, a protective glass overcoat is applied, while barrier terminations receive nickel barrier electroplating and pure tin finishing for dependable soldering.

The general-purpose GR family spans footprints from miniature 0201 packages up to heavy-duty 2512 chips rated at one watt, offering resistance from zero ohm jumpers to 22 Mohm.

The specialized VR family withstands continuous working voltages up to 3000 V, while SR resistors provide elevated pulse handling capacity to absorb transient energy in power converters.

Automotive grade chip resistors engineered to AEC-Q200 standards

Passive components for vehicular electronics must satisfy stringent durability and temperature endurance demands. GiantOhm automotive resistors are produced in dedicated production cells complying with AEC-Q200 stress testing requirements.

Each component undergoes continuous automated optical inspection (AOI) and electrical parameter verification.

The product line encompasses the AG general automotive family, AV high voltage versions, AL low resistance units, and AS pulse resistant components.

Devices maintain stable performance from minus 55 to plus 155 Celsius, preventing terminal fracturing under thermal cycling, road vibration, and engine compartment temperature shifts.

Anti-sulfuration technology for hostile industrial and chemical environments

In industrial sectors and vehicular environments with elevated atmospheric sulfur gas concentrations, standard chip resistors face silver sulfuration: sulfur reacts with inner silver electrodes to generate non-conductive silver sulfide, triggering open-circuit failures.

To counter this degradation, GiantOhm developed specialized AA and GF anti-sulfur resistor families.

A protective barrier shields the inner conductive metallurgy from exposure to sulfur fumes and aggressive chemical vapors.

The resistors pass rigorous ASTM-B809 flowers-of-sulfur tests without parameter drift, ensuring dependable operation near vehicle exhausts, internal combustion powertrains, and chemical processing automation.

High-precision thin film resistors and metal alloy current sensing shunts

For analytical instrumentation, medical monitoring systems, and analog sensors, GiantOhm manufactures TF series precision thin film chip resistors.

Uniform nichrome alloy thin films are deposited via vacuum magnetron sputtering followed by laser trimming, achieving tight resistance tolerances down to 0.05% and ultra-low thermal drift down to 5 ppm/C.

In power electronic converters, servo drives, and battery management systems (BMS), engineers deploy LS and ST series metal alloy current sensing resistors and shunts.

Solid alloy resistive elements deliver milliohm ratings from 0.5 to 100 milliohm with power dissipation up to 5 W, minimal parasitic inductance, and Kelvin four-terminal connection compatibility.

Surface mount soldering guidelines and quality verification procedures

GiantOhm surface mount components are packaged in standardized tape and reel formats engineered for high-speed automated pick-and-place feeders.

The three-layer terminal plating prevents silver leaching during solder contact, ensuring excellent wetting characteristics with both lead-free and tin-lead solder alloys.

Reflow soldering parameters accommodate convection furnace profiles with peak temperatures up to 260 Celsius, as well as wave soldering processes.

Before initiating mass assembly runs, production teams are advised to perform incoming inspection of resistance values against engineering bill-of-materials (BOM) records and maintain dry storage protocols.
