As a leading ODM/OEM provider in global flexible printed circuit (FPC), PCB fabrication, and rigid-flex PCB assembly industries, Shenzhen Huaruixin Electronics Co., Ltd. anchors its development in E-E-A-T principles—Experience, Expertise, Authoritativeness, and Trustworthiness. Our end-to-end quality control (QC) system, from FPC prototype manufacturing to bulk delivery, ensures compliance with international standards and maximizes collaborative value for clients worldwide. Below we detail the critical QC workflows for post-production FPCs and Huaruixin’s competitive strengths.

1. Precision Inspection & Packaging: QC Cornerstones for FPC Reliability

Post-fabrication, multi-stage inspections eliminate defects before anti-static packaging, forming the final barrier to ensure FPC performance. This process adheres strictly to IPC-A-6013 (Flexible Printed Boards Standard) and customer-specific requirements.

1.1 Dual-Mode Visual Inspection for FPC Fabrication

Manual Dimensional & Aesthetic Checks: Certified inspectors conduct meticulous assessments against IPC standards, focusing on:

Circuit integrity (no open circuits, short circuits, or copper oxidation);

Coverlay quality (zero bubbles, warpage, or delamination);

Stiffener bonding (100% adhesion without peel-back);

Surface condition (scratch-free, no solder balls >0.3mm, or ink residue);

Substrate flatness (bending ≤0.75mm per 100mm per IPC specs) .

Automated AOI & Metrology Integration: Our advanced Automatic Optical Inspection (AOI) systems deliver 5μm-level defect detection for micro-issues like trace thinning or pad misalignment . For quantitative precision, we complement AOI with Bamtone line width testers—ideal for verifying conductor spacing and line width consistency across flexible substrates . This dual-system approach boosts inspection efficiency by 40% while eliminating human error.

1.2 Industrial-Grade FPC Packaging Solutions

Qualified FPCs undergo ESD-safe packaging using:

Anti-static shielding bags (for single-unit protection);

Moisture barrier bags (MBBs) with desiccants (to maintain <10% RH for high-reliability applications);

Reinforced corrugated cartons with custom inserts (preventing flex damage during global shipping).

2. Huaruixin’s Capabilities: Driving FPC Quality at Scale

Our QC excellence stems from integrated manufacturing, R&D, and compliance frameworks—critical for quick-turn FPC production and custom solutions.

2.1 State-of-the-Art FPC Manufacturing Bases

Spanning 20,000+㎡, our facilities house:

High-speed FPC etching lines (supporting 3μm line/space);

Automated stiffener lamination stations;

Cleanroom assembly zones (Class 1000) for medical/automotive FPCs.

This infrastructure enables 100k+ FPC units daily with <0.05% defect rates.

2.2 Custom FPC/Rigid-Flex R&D Expertise

Our engineering team specializes in:

Prototype-to-production workflows (3-day turnaround for FPC prototypes);

Industry-specific designs (automotive ADAS FPCs, medical device rigid-flex PCBs, aerospace high-temperature FPCs);

Material optimization (LCP vs. PI substrates for high-frequency applications).

2.3 Globally Recognized Quality Certifications

We maintain rigorous compliance with:

GB/T19001-2016/ISO 9001:2015 (Quality Management System);

IAF International Accreditation & CNAS Certification;

IPC-A-6013 & IPC-6012 (PCB/FPC Performance Standards).
