High-Reliability Ceramic Thick Film Circuit Board for Motorcycle Fuel Gauge | China Suppliers & Factory
Product Description
Dongguan Jianchuang Electronic Technology Co., Ltd. offers a high-performance Motorcycle Fuel Gauge Ceramic Thick Film Circuit Board designed for accurate fuel level detection in motorcycle fuel tanks. This ceramic thick film circuit board is built on a 96% alumina (Al2O3) ceramic substrate and manufactured using precision thick film screen printing technology, providing reliable and stable resistance output proportional to fuel level changes.
Product Features
Superior Ceramic Substrate
Built on 96% Al2O3 alumina ceramic, providing exceptional thermal stability (24 W/m·K), high dielectric strength (>15 kV/mm), and excellent mechanical durability. Unlike conventional FR4 PCB, the ceramic substrate withstands prolonged fuel immersion without degradation or delamination.
Precision Thick Film Technology
Silver-Palladium (Ag-Pd) conductive traces and resistive elements are screen-printed and fired at 850°C, creating permanent, stable electrical paths with resistance tolerances as tight as ±1%. The thick film process ensures consistent performance across high-volume production runs.
Fuel-Resistant Glass Passivation
A specialized glass passivation coating protects the circuit from fuel absorption, chemical corrosion, and electrical leakage during continuous immersion in gasoline, ethanol blends (E10), and diesel fuel. This ensures reliable long-term operation inside the fuel tank environment.
Wide Temperature Range
Engineered for reliable operation from -40°C to +150°C, making the circuit board suitable for motorcycles operating in extreme climate conditions — from freezing winters to scorching desert heat.
Long Service Life
Designed and tested for over 100,000 operational cycles with consistent electrical performance, minimizing warranty returns and ensuring customer satisfaction.
Compact & Lightweight
The thin ceramic substrate (0.635mm or 1.0mm thickness options) creates an ultra-compact sensor assembly that fits easily into motorcycle fuel tanks without taking up excessive space or adding weight.

Working Principle
The ceramic thick film circuit board is integrated with a float-arm mechanism inside the motorcycle fuel tank. As the fuel level changes, the float arm moves a sliding contact across the precision thick film resistor track, producing a variable resistance output. This signal is transmitted to the fuel gauge indicator on the motorcycle dashboard, providing real-time fuel level readout to the rider.
