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 (ПИ) or polyester (ДОМАШНИЙ ПИТОМЕЦ). A precise etching process forms conductive traces on this thin flexible substrate. Unlike a rigid печатная плата, an FPC can bend, fold, and twist in 3D space. This flexibility perfectly supports modern trends toward smaller, легче, and more integrated electronics.

IPC-6013E-2021 defines flexible printed boards as single-sided, двусторонний, многослойный, or rigid-flex multilayer structures. These may include stiffeners, plated through holes (ПТХ), 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 (Слой & Структура)

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

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

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

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

By Flexing Condition (Installation & Использовать)

• 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°Ф).

• 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. Потребительская электроника – Smartphones (отображать, camera, battery connections), таблетки, ноутбуки, умные часы, TWS earbuds, беспилотники.

2. Автомобильная электроника – In-vehicle displays, модули камеры, датчики, системы управления батареями (Бит), Адас, светодиодные фонари.

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

4. Industrial control – Robot joints, precision instruments, internal wiring harnesses, IoT terminals.

5. Аэрокосмическая промышленность & защита – Lightweight interconnects for satellites, missiles, радиолокационные системы.

6. 5G telecom – Base station antennas, ВЧ-модули внешнего интерфейса, high-speed signal lines.

BCC Research notes that multilayer FPCs hold 39.4% of the global market. This share keeps growing because smartphones, носимые устройства, автомобильная электроника, and medical devices demand higher circuit density.

FPC Base Materials and Performance Features

Primary Base Materials

• ПИ (Полиимид) – Excellent high-temperature resistance (-40°С до +125°С) and dimensional stability. Top choice for high-end FPC.

• ДОМАШНИЙ ПИТОМЕЦ (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 печатная плата: 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 & прозрачный – Determine minimum safe distance based on working voltage. For 1kV DC/AC peak, степень загрязнения 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. Контроль импеданса – 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: ПИ, ФР4, 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.

Production Flow Overview

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

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

2. Бурение – Mechanical or лазерное бурение. Minimum hole diameter 0.1mm.

3. Electroless copper / покрытие – 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, ФР4, or steel stiffeners on reinforced areas.

7. Чистота поверхности – ENIG (Химическое никель, иммерсионное золото) or OSP.

8. Outer contour – Die punching or laser cutting.

9. Электрическое испытание – Continuity and impedance tests (deviation ≤ ±8%).

10. FQC & упаковка – АОИ, dimensional inspection, and final packing.
