2L Heavy Copper Automotive Battery Management (BMS) Flex PCB
Engineered for modern electric vehicle battery architecture, this heavy-copper flexible circuit replaces bulky wire harnesses with a flat, space-efficient interconnect matrix. Utilizing thick copper conductors bonded to flame-retardant polyimide, it ensures stable low-resistance cell voltage sensing, temperature monitoring, and robust high-current busbar integration.
- Layer Count: 2 Layers
- Base Material: Thick Polyimide Substrate (50 µm / 75 µm) + 2oz/3oz Heavy Rolled-Annealed Copper
- Application: Electric vehicle (EV) battery pack cell-to-pack (CTP) harnesses, energy storage systems (ESS), and high-power DC/DC conversion modules.
Dynamic Flexibility Meets Sub-Mil Precision: In-House Flex PCB Fabrication
From ultra-thin single-sided flex circuits to complex high-density multilayer and rigid-flex constructions, XinshunPCB integrates roll-to-roll (R2R) handling, UV laser micro-machining, and high-bond vacuum lamination to deliver dynamic flex boards that endure extreme bending fatigue without signal degradation.
Adhesiveless Polyimide & Extreme Dynamic Flexing Endurance
Engineered with premium adhesiveless polyimide (PI) base laminates paired with high-ductility rolled-annealed (RA) copper foils. By precisely balancing copper grain orientation, matching flexible coverlay thicknesses, and positioning conductors along the calculated neutral bending axis, our flexible circuits withstand over 100,000+ continuous dynamic flexing cycles with zero trace micro-cracking or impedance drift, making them ideal for high-cycling camera gimbals, robotic joints, and wearable medical sensors.
Sub-Mil Laser Micro-Drilling & High-Density Interconnect (FPC HDI)
Overcoming spatial constraints in miniaturized electronics through advanced UV laser micro-machining and roll-to-roll processing. We achieve fine trace line width and spacing down to 35 µm / 35 µm (1.4 mil), microvia hole diameters down to 50 µm, and high-precision laser coverlay pocket profiling. Combined with high-temperature vacuum thermosetting lamination, our processes guarantee void-free coverlay encapsulation around dense conductor traces without air entrapment or adhesive squeeze-out.
Multi-Material Stiffener Integration & Precision Surface Finishing
Configured for high-reliability connector retention and effortless SMT component assembly. We provide automated CCD optical alignment and vacuum hot-press bonding for diverse stiffener options—including FR-4, 304 Stainless Steel, Aluminum, and extra-thick Polyimide—using thermosetting adhesive films or 3M conductive/non-conductive tapes. Paired with chemical immersion gold (ENIG) or hard gold electrolytic plating on contact fingers, our boards ensure zero pad lifting and robust contact reliability on ultra-fine 0.20 mm pitch ZIF/FPC connectors.
High-Precision & Dynamic Flex PCB Fabrication
Pushing the boundaries of miniaturization, dynamic bending endurance, and high-density flexible interconnects. From sub-mil trace routing and UV laser microvias to multi-material stiffener bonding and integrated EMI shielding, our automated in-house manufacturing ensures your flexible circuits are robust, scalable, and IPC-6013 Class 3 compliant.

Frequently Asked Questions
Find quick answers about flexible PCB materials, bend radius design rules, dynamic cycling endurance, stiffeners, and manufacturing capabilities.
All flexible circuits are manufactured and inspected in strict accordance with IPC-6013 Class 2 or Class 3 standards. Our testing protocol includes:
100% Electrical Netlist Testing: High-speed flying probe testing verifying continuity and absence of micro-shorts down to low-resistance thresholds.
Automated Optical Inspection (AOI): Inline inspection checking conductor line widths, spacing, and coverlay alignment accuracy.
Mechanical & Thermal Reliability Testing: Dynamic bending fatigue endurance tests (evaluating 100,000+ continuous cycles), thermal stress solder float testing (288°C, 10 seconds), and microsection inspection to verify plated through-hole (PTH) barrel copper thickness (≥ 20–25 µm).
