As global demand for compact, durable electronics surges, businesses seek trusted FPC/PCB ODM manufacturers that deliver reliable flexible printed circuits (FPC), rigid PCBs, and rigid-flex boards. Shenzhen Huaruixin Electronics Co., Ltd.—a leader in flexible circuit manufacturing—combines 100% electrical testing protocols, advanced production capabilities, and globally recognized certifications to meet the stringent requirements of automotive, medical, and consumer electronics industries. Below is a detailed breakdown of our expertise, designed to address your most critical FPC quality and supply needs.

1. 100% Electrical Testing: The Backbone of FPC Reliability

FPCs rely on precise signal transmission and insulation to perform in dynamic applications (e.g., automotive sensors, medical wearables). At Huaruixin, comprehensive electrical testing is mandatory for every unit—no exceptions—using industry-leading equipment and protocols:

Open/Short Testing with Flying Probe Technology: Our automated flying probe testers contact FPC pads and interfaces to eliminate micro-shorts and open circuits—common flaws that cause device failure. This in-circuit test (ICT) ensures all conductive pathways adhere to Gerber data specifications .

Characteristic Impedance Verification: Using Time Domain Reflectometers (TDR), we calibrate impedance to 50Ω, 75Ω, or custom values critical for high-speed signal integrity. Stable characteristic impedance prevents signal distortion in IoT devices and aerospace avionics .

Dielectric Withstand Voltage Test: We apply 500V AC (or client-specified levels) between circuits and polyimide (PI) substrates to detect insulation breakdown. This test safeguards against flashover and ensures compliance with automotive IEC standards .

2. FPC/PCB Manufacturing Excellence: Scale, R&D, and Certification

Our ability to deliver custom FPC solutions stems from end-to-end expertise aligned with global quality benchmarks:

Large-Scale Smart Production Bases: Equipped with automated lamination lines and coverlay bonding systems, our facilities produce high-density FPCs and rigid-flex boards with tight tolerance control. This scalability meets high-volume orders for consumer electronics and industrial robotics .

Industry-Tailored R&D: Our engineers specialize in designing dynamic flex FPCs (for million-cycle bending) and static FPCs (for compact assemblies). We optimize PI and PET substrate selections, copper foil thickness (electrolytic vs. rolled), and bonding layer materials to match your application’s environmental demands .

Globally Recognized Quality Systems: We hold GB/T19001-2016/ISO 9001:2015 certification, plus IAF international accreditation and CNAS laboratory recognition. These credentials validate our commitment to consistent production and regulatory compliance (e.g., medical device ISO 13485 alignment) .

3. Partner with Huaruixin: Your FPC/PCB Solution Provider
