Product Description
China Chaosheng Electronics Large scale Color Printing Machine Flexible FPC Description
>Core Highlights: * * Non splicing integrated ultra long FPC, capable of up to 15 meters of continuous soft board * *, fully automatic roll to roll production line, solving the pain points of traditional segmented FPC length limitation, multi segment splicing, excessive connectors, signal attenuation, high failure rate, etc
1、 Core production capacity&basic specification parameters
Ultimate Dimensional Capability
-Maximum continuous length: 200000mm (200 meters), single without splicing or intermediate adapter
-Maximum width: 1100mm
-Conventional production specifications: 1m to 4m ultra long FPC
-Board structure: single-sided, double-sided, multi-layer flexible board, rigid flex bonding board Rigid Flex
-Total thickness range of finished product: 0.05mm~1.2mm
-Minimum line width/spacing: * * 0.05mm (50 μ m) * *; Precision models can achieve 0.03mm
-Minimum aperture: mechanical hole 0.15mm, laser micro hole 0.075mm
-Impedance control: differential 100 Ω/single ended 50 Ω, tolerance ± 5%; High speed high-frequency board ± 3%
Base material (customizable)
1. * * DuPont PI (Polyimide) * *: Standard main substrate, 25 μ m/50 μ m/75 μ m/125 μ m, optional adhesive free/adhesive substrate, high temperature resistance, bending resistance, low deformation
2. LCP liquid crystal polymer material: high-frequency 5G, millimeter wave, extremely low dielectric loss
3. GHPL and PET substrates: cost optimized version, ordinary signal cable
4. Conductor copper foil: Rolled copper RA (priority dynamic bending), electrolytic copper ED
Surface treatment process
-Sinking gold ENIG: BGA pads, static soldering areas
Selective electroplating thick hard gold fingers * *: nickel 3-5 μ m+hard gold 0.8-2.0 μ m, wear-resistant for insertion and removal, dedicated for connector contacts at both ends
-Sinking tin, sinking silver, OSP, ENEPIG palladium (military, automotive high reliability)
2、 Roll to roll R2R continuous production process flow (special for ultra long FPC)
Traditional FPC single chip production (SBS) can generally only achieve a maximum length of 1-2 meters; **Roll to roll continuous processing is the key process for achieving over ten meters of ultra long soft board
1. Roll feeding: The entire roll of PI substrate+copper foil is unwinding, with constant tension servo control throughout the process to prevent stretching deformation and copper foil elongation displacement
2. Roll to roll dry film pressing, CCD automatic correction, correction accuracy ± 0.025mm
3. Continuous exposure: Roll shaped graphic transfer ensures consistent line size throughout the entire roll from start to finish
4. Continuous DES wet process (development etching film stripping) with dedicated anti indentation rollers to avoid roller marks on the surface of long plates
5. Roll to roll cover film vacuum bonding: PI protective film hot pressed, no bubbles, no warping, ultra long board size stability control
6. Roll punching/laser drilling, metalization of via holes
7. Multilayer board: continuous semi cured sheet bonding, roll to roll vacuum lamination
8. Selective electroplating/full board surface treatment, long-distance solution uniformity control
9. Roll to roll laser shape cutting and slitting (UV laser cutting, smooth edges without cracking)
10. Online AOI optical inspection+continuous flying needle electrical on-off and impedance full inspection
11. Finished product winding, segmented cutting, protective film application, anti-static packaging
Key process difficulty control
-Full process tension closed-loop control to prevent inconsistent stretching and expansion of ultra long sheets
-The circulation of the medicine is uniform to avoid thickness deviation of the coating at the head and tail of the long board
-Laser cutting replaces mold stamping, forming ultra long irregular, L-shaped, and curved shapes in one, without the need for segmented splicing
3、 The advantages of roll to roll ultra long FPC compared to ordinary segmented FPC
1. * * Integrated without splicing * *: eliminates intermediate connectors, reduces fault points, improves reliability by more than 80%, improves signal integrity, stabilizes long-distance transmission impedance, and reduces voltage drop
2. High bending life: Rolled copper+roll to roll stress free process, dynamic bending up to 1 million times
3. Lightweight: Compared to traditional wiring harnesses, it can reduce weight by up to 60% and save internal space of the equipment
4. Quality consistency: Whole roll production, with minimal deviation in head and tail lines, copper thickness, and coating parameters
5. Suitable for large-scale continuous wiring, with higher production efficiency and material utilization rate of 92% -95%, reducing costs
4、 Target application industry
New energy vehicles * *: BMS battery cables, chassis long-distance wiring harnesses, car lights, vehicle sensors long line connections, military connectors, equipment connectors, weapon connectors, aerospace connectors, radar antennas, LED light strips, large screens, backlight sources, IoT tags, etc
Industrial automation, robots, drag chain cables * *: flexible wiring for long-distance activities inside equipment
-Medical equipment: large imaging equipment, detection instruments, ultra long flexible interconnection
-Aerospace and unmanned aerial vehicles: lightweight long cables replace traditional wire harnesses
-5G communication, base stations, large display panels
-Internal long cables for photovoltaic equipment, large mechanical equipment, and intelligent equipment
