What Is an FPC Flexible Circuit Board? – Product Overview

FPC stands for Flexible Printed Circuit Board. It is also called a flex board or flexible circuit. The insulation base material is polyimide (PI) or polyester (애완 동물). A precise etching process forms conductive traces on this thin flexible substrate. Unlike a rigid PCB, an FPC can bend, fold, and twist in 3D space. This flexibility perfectly supports modern trends toward smaller, 거룻배, and more integrated electronics.

IPC-6013E-2021 defines flexible printed boards as single-sided, 양면, 다층, or rigid-flex multilayer structures. These may include stiffeners, plated through holes (PTH), and blind/buried vias. UGPCB strictly follows IPC-2221 design standards and IPC-6013 performance specifications. Every FPC we produce meets international industry requirements.

UGPCB FPC Technical Parameters at a Glance

Product Classification Based on IPC-6013

IPC-6013 defines three classification dimensions.

By Type (층 & 구조)

By Performance Class (Use Scenario) – IPC-6011 & IPC-6013

• 수업 1 – General electronic products. Minimum reliability requirement for consumer electronics. Least strict testing.

• 수업 2 – Dedicated service electronics. Higher performance for communication and industrial control equipment.

• 수업 3 – High-performance electronics. Strict reliability for medical, 항공우주, and military applications.

By Flexing Condition (Installation & 사용)

• Use A – Withstands single bending during installation.

• Use B – Withstands specified repeated flex cycles.

• Use C – Suitable for high-temperature environments above 105°C (221° F).

• Use D – UL certified (meets UL 94 and UL 796F).

Applications of FPC Flexible Circuit Boards

FPC’s thin and flexible nature enables wide use in:

1. 소비자 전자 장치 – Smartphones (표시하다, camera, battery connections), 정제, 노트북, 스마트워치, TWS earbuds, 드론.

2. 자동차 전자 제품 – In-vehicle displays, 카메라 모듈, 센서, 배터리 관리 시스템 (BMS), ADAS, LED 조명.

3. 의료기기 – Portable monitors, hearing aids, endoscopes, wearable health trackers, implantable devices.

4. 산업 통제 – Robot joints, 정밀 기기, internal wiring harnesses, IoT terminals.

5. 항공우주 & 방어 – Lightweight interconnects for satellites, missiles, 레이더 시스템.

6. 5G telecom – Base station antennas, RF front-end modules, high-speed signal lines.

BCC Research notes that multilayer FPCs hold 39.4% 글로벌 시장의. This share keeps growing because smartphones, 웨어러블, 자동차 전자, and medical devices demand higher circuit density.

FPC Base Materials and Performance Features

Primary Base Materials

• PI (폴리이미드) – Excellent high-temperature resistance (-40°C ~ +125°C) and dimensional stability. Top choice for high-end FPC.

• 애완 동물 (Polyester) – Lower cost. Suitable for consumer applications without extreme temperature requirements.

Top industry suppliers use adhesiveless materials from Panasonic and DuPont, plus adhesive-based materials and coverlays from Sunky.

Key Performance Features

Design Guidelines and Working Principle

How an FPC Works

An FPC works like a rigid PCB: copper traces on an insulating substrate provide electrical connections between components. The difference is the flexible substrate (PI/PET). This allows the board to bend in 3D space, enabling complex and compact interconnects inside tight product enclosures.

Key Design Points per IPC-2221

1. Conductor spacing & 정리 – Determine minimum safe distance based on working voltage. For 1kV DC/AC peak, 오염도 2, uncoated environment, IPC-2221 recommends clearance ≥2.0mm.

2. Minimum trace/space – UGPCB supports 1.5mil/1.5mil. We suggest 3/3mil or above to lower manufacturing difficulty and cost.

3. Via design – Outer diameter should be at least 0.2mm larger than inner diameter (≥0.25mm recommended). A practical balance: 0.3mm inner, 0.55mm outer.

4. 임피던스 제어 – For high-frequency signals, we offer controlled impedance within ±10% tolerance.

5. Stiffener design – Add stiffeners at component mounting areas or ZIF connector interfaces. Common materials: PI, FR4, steel.

6. Bending area design – Avoid vias and pads in repeated bend zones. Route traces at 90° or with arcs. Place the bend centerline on copper-free areas to maximize flex life.

생산 흐름 개요

UGPCB follows IPC-6013 performance specifications through these key steps:

1. Material cutting – Cut PI/PET base material to size.

2. 교련 – Mechanical or 레이저 드릴링. Minimum hole diameter 0.1mm.

3. Electroless copper / 도금 – Deposit conductive copper on hole walls to form PTH.

4. Circuit patterning – Laminate dry film → expose → develop → etch → strip film to create fine circuits.

5. Coverlay lamination – Apply coverlay as solder mask protection.

6. Stiffener attachment – Bond PI, FR4, or steel stiffeners on reinforced areas.

7. 표면 마감 – ENIG (무전해 니켈 침지 금) or OSP.

8. Outer contour – Die punching or laser cutting.

9. Electrical test – Continuity and impedance tests (deviation ≤ ±8%).

10. FQC & 포장 - AOI, dimensional inspection, and final packing.
