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 (BICHO DE ESTIMAÇÃO). A precise etching process forms conductive traces on this thin flexible substrate. Unlike a rigid PCB, an FPC can bend, dobrar, and twist in 3D space. This flexibility perfectly supports modern trends toward smaller, isqueiro, and more integrated electronics.

IPC-6013E-2021 defines flexible printed boards as single-sided, frente e verso, multicamada, 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.

Product Classification Based on IPC-6013

IPC-6013 defines three classification dimensions.

By Type (Camada & Estrutura)

Por classe de desempenho (Use Scenario) – IPC-6011 & IPC-6013

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

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

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

By Flexing Condition (Installation & Usar)

• Usar um – Withstands single bending during installation.

• Usar B – Withstands specified repeated flex cycles.

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

• Usado – 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. Eletrônica de consumo – Smartphones (display, camera, battery connections), comprimidos, notebooks, relógios inteligentes, TWS earbuds, drones.

2. Eletrônica automotiva – In-vehicle displays, módulos de câmera, sensores, sistemas de gerenciamento de bateria (Bms), ADAS, Luzes LED.

3. Dispositivos médicos – Portable monitors, aparelhos auditivos, endoscopes, wearable health trackers, implantable devices.

4. Controle industrial – Robot joints, instrumentos de precisão, internal wiring harnesses, IoT terminals.

5. Aeroespacial & defesa – Lightweight interconnects for satellites, missiles, sistemas de radar.

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

BCC Research notes that multilayer FPCs hold 39.4% do mercado mundial. This share keeps growing because smartphones, wearables, eletrônica automotiva, and medical devices demand higher circuit density.

FPC Base Materials and Performance Features

Primary Base Materials

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

• BICHO DE ESTIMAÇÃO (Poliéster) – 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 & liberação – Determine minimum safe distance based on working voltage. For 1kV DC/AC peak, grau de poluição 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. Controle de impedância – For high-frequency signals, we offer controlled impedance within ±10% tolerance.

5. Projeto de reforço – 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.

Visão geral do fluxo de produção

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

1. Corte de materiais – Cut PI/PET base material to size.

2. Perfuração – Mechanical or perfuração a laser. Minimum hole diameter 0.1mm.

3. Cobre sem eletricidade / revestimento – Deposit conductive copper on hole walls to form PTH.

4. Padronização de circuito – 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. Acabamento superficial - CONCORDAR (Ouro de imersão em níquel eletrolítico) or OSP.

8. Outer contour – Die punching or laser cutting.

9. Teste elétrico – Continuity and impedance tests (deviation ≤ ±8%).

10. CQF & embalagem - AOI, dimensional inspection, and final packing.
