As the automotive industry embraces electrification, intelligent systems, and compact designs, the demand for advanced electronic components is rapidly growing. Among the critical enablers of this transformation is the Flexible Printed Circuit (FPC). With their thin, bendable form factor and high-performance capabilities, FPCs are increasingly used in a variety of automotive applications, from sensors and lighting to battery packs and power management systems.
A Flexible Printed Circuit is a type of electronic circuit built on a flexible substrate, typically polyimide or polyester film. Unlike traditional rigid PCBs (Printed Circuit Boards), FPCs can bend, fold, and twist without breaking. This flexibility makes them ideal for installation in compact or irregularly shaped spaces—common in modern automotive designs.
FPCs offer excellent electrical performance while reducing weight and space, making them an essential component in today’s intelligent and electric vehicles.
To meet the complex demands of automotive systems, high-quality FPCs—like those offered by HECTACH—must possess a combination of performance, reliability, and safety characteristics. Below are the most important attributes:
FPCs can be bent or folded to fit within tight spaces, such as dashboard interiors, door panels, or compact battery modules. This design adaptability is essential for modern vehicles that demand both miniaturization and performance.
Automotive-grade circuits require extremely accurate patterns to ensure reliable signal transmission and power delivery. HECTACH uses advanced etching processes that allow for micro-scale precision, ensuring each circuit pathway is clean, consistent, and optimized for performance.
In critical applications like power batteries and sensors, insulation and voltage resistance are key to maintaining safe operation. HECTACH’s FPCs are engineered with advanced materials that can withstand high voltage and prevent short circuits—even in high-humidity or high-temperature environments.
Automotive environments are subject to vibration, heat, moisture, and exposure to corrosive elements. FPCs must perform consistently under these conditions. HECTACH addresses this with:
Corrosion-resistant materials
Temperature-tolerant substrates
Stress-relief design features
Rigorous durability testing
Today’s vehicles—especially electric vehicles (EVs) and hybrid electric vehicles (HEVs)—require compact, reliable, and high-density electronic systems. Here’s why Flexible Printed Circuits are perfectly suited for this challenge:
Space Optimization: Modern vehicle design prioritizes compact integration. FPCs offer a thinner and lighter alternative to traditional wire harnesses.
Weight Reduction: Lighter circuits contribute to overall vehicle efficiency, especially in EVs where weight directly affects range.
High Durability: With advanced materials and protective coatings, FPCs can operate in extreme automotive environments.
Design Freedom: Their foldability and bendability allow engineers to create innovative circuit layouts even in curved or non-linear spaces.
FPCs are used throughout the vehicle—enabling smarter, safer, and more efficient operation. Below are the key automotive applications:
Modern vehicles rely on sensors to monitor everything from temperature and pressure to acceleration and lane positioning. FPCs play a crucial role in connecting these sensors to the vehicle’s central control systems.
FPC advantages in sensors:
High signal integrity
Easy integration in tight locations
Resistance to vibration and temperature fluctuations
Applications include:
Tire Pressure Monitoring Systems (TPMS)
Battery temperature and voltage sensors
Rain and light sensors for automated wipers and headlights
From LED headlamps to ambient interior lighting, lighting has become a design and safety feature in modern cars. FPCs allow designers to implement flexible lighting solutions that can wrap around contours or fit within slim housings.
FPC benefits in lighting:
Flexibility to fit custom lighting shapes
Enhanced durability in hot and humid environments
High-precision current paths for consistent illumination
Electric and hybrid vehicles require efficient and reliable power distribution. FPCs are used within battery modules to manage current flow, monitor individual cell conditions, and ensure safety.
HECTACH’s FPCs for battery systems offer:
Stable operation under high temperature and humidity
Resistance to electrolytic corrosion and salt spray
High-precision etched fuses with stress-relief waist grooves
QR code traceability for advanced quality control
These FPCs are designed with single-sided etching, a typical thickness of 0.14±0.03mm, and incorporate bent nickel plates to improve structural adaptability and shock resistance.
As comfort features increase, FPCs are often used in movable parts like sunroofs and power-adjustable seats. Their compact form makes routing through tight, mobile components easy and reliable.
Benefits:
Minimal wear over long usage cycles
Foldable without compromising electrical performance
Compatible with automation controls and sensors
FPCs also support smaller but essential systems such as:
Heated mirrors
Door lock actuators
USB power outlets
Interior LED strips
