At Kaboer, we don’t just manufacture circuit boards—we engineer solutions that redefine reliability in automotive electronics. Our 2-layer rigid-flex PCB, meticulously designed for automotive shift knobs, embodies our commitment to precision, durability, and innovation. Every technical detail is crafted to meet the toughest automotive standards, ensuring your shift knob systems perform flawlessly, mile after mile.
Rigid-Flex Circuit Board
Kaboer’s hybrid design merges rigid FR4 sections (for stable component mounting) with flexible polyimide segments, allowing seamless adaptation to the shift knob’s contours. This eliminates bulky connectors, reduces assembly complexity, and enhances overall system efficiency—exactly what modern automotive design demands.
2 Layers
Our 2-layer configuration strikes the perfect balance between functionality and simplicity, delivering efficient signal paths for critical shift knob electronics (gear position sensors, indicator lights) without unnecessary bulk. It’s engineered to keep your systems lightweight and responsive.
0.15mm / 0.1mm
Precision is non-negotiable at Kaboer. Our ultra-fine lines and spacing ensure dense circuitry fits into the compact shift knob housing, supporting multiple functions while maintaining uncompromised signal integrity—even in high-vibration environments.
-
FPC (Flexible Section): 0.15mm
-
Overall Thickness (T): 1.6mm
The thin, flexible section bends smoothly to match the shift knob’s design, while the 1.6mm overall thickness guarantees structural stability in high-stress areas. It’s the ideal blend of flexibility and rigidity, tailored for automotive use.
1 Ounce
With 35μm of high-purity copper, our PCBs deliver superior conductivity for consistent current flow, even under extreme thermal cycles and vibrations. This means fewer failures, less downtime, and longer service life for your shift knob systems.
50μm
The 50μm polyimide film in flexible sections offers exceptional insulation and mechanical strength, withstanding the constant movement, temperature swings, and humidity of automotive interiors. It’s built to endure what daily driving throws at it.
ENIG (Electroless Nickel Immersion Gold) 2–3μm
Kaboer’s high-adhesion ENIG finish is a game-changer: the nickel layer resists corrosion and ensures strong solder joints, while the 2–3μm gold layer prevents oxidation and guarantees long-term conductivity. It’s the protection your shift knob electronics need for years of reliable performance.
0.1mm
Our strict 0.1mm tolerance ensures a perfect fit in tight shift knob assemblies, eliminating interference with mechanical components and simplifying your production process. No more rework—just seamless integration.
Shengyi TG170 Laminate
We choose only the best substrates. Shengyi’s TG170 laminate (Tg 170°C) handles cabin temperatures up to 125°C, ensuring stability under extreme heat. It’s a testament to our commitment to using materials that meet automotive-grade rigor.
-
Proven Reliability: Our boards undergo rigorous testing—AOI inspection, four-wire resistance checks, continuity tests, and copper pad validation—all to meet IATF 16949 standards. When you choose Kaboer, you choose a product that’s been put through its paces.
-
Tailored for Automotive Needs: High adhesion, vibration resistance, and thermal stability—every feature addresses the unique challenges of automotive environments. Your shift knobs deserve a PCB that’s as tough as the vehicles they’re in.
-
