Data Sheet

1. PCB Structural & Process Control

The PCB adopts an upper-lower asymmetric structure, and Maxipcb maintains the board warpage at ≤ 0.75%. For the rigid board section, mechanical blind milling is adopted for window opening to prevent damage to the flexible board during cover removal. The flexible section is formed by laser, with a shape tolerance of ± 0.05mm.

2. Product Application & Global Market

Maxipcb’s products are widely applied in industrial equipment, medical equipment, automotive electronics, communications, digital products and aerospace fields. Its products are exported to global markets including Germany, France, the United States, Australia and Sweden, delivering convenient and efficient one-stop services to customers worldwide.

3. Quality Certification & Assurance

Maxipcb holds UL certifications for various materials and thick PI thick copper products, and has passed ISO9001 quality management system and SGS RoHS certification, providing reliable quality guarantee for all products. Since its establishment, the company has focused on R-FPCB R&D and manufacturing, becoming a trusted partner for global customers.

4. R-FPCB (Rigid-Flex PCB) Overview

4.1 Definition & Structural Features

R-FPCB is a composite circuit board integrated by laminating flexible FPC and rigid PCB substrates, enabling three-dimensional design to support the miniaturization of smart health assistants, with high requirements for manufacturing precision. A single R-FPCB can replace multi-connector composite PCBs, improving performance and stability while maximizing space utilization. A standard 4-layer R-FPCB adopts a PI core with copper foils on both sides, laminated with FR4 rigid layers to form a high-reliability structure.

4.2 Manufacturing Characteristics

R-FPCB manufacturing involves multiple materials and complex processes, with a longer production cycle than standard rigid PCBs (the cycle of a 4-layer R-FPCB is 5-7 times that of a standard 4-layer rigid PCB). Maxipcb relies on mature process control and advanced equipment to achieve a balance between efficiency and precision, meeting the prototype and mass production needs of smart health assistants.

5. Core Advantages of R-FPCB for Smart Health Assistants

5.1 Space-Saving & Cost Optimization: The integrated structure of R-FPCB eliminates connectors and HotBar processes, optimizing space utilization for ultra-small and ultra-thin smart health assistants, reducing product volume and saving component/process costs.

5.2 Enhanced Signal Reliability: For smart health assistants requiring real-time physiological data detection, R-FPCB shortens the signal transmission path (simplified from PCB-connector-FPC-connector-PCB to PCB-FPC-PCB), reducing signal attenuation. Maxipcb further optimizes signal transmission performance to ensure stable and accurate data transmission.

5.3 Simplified Assembly & Efficiency: By reducing connectors, R-FPCB decreases SMT mounting and overall assembly man-hours, eliminating FPC insertion and HotBar processes, and simplifying BOM to lower management and inventory costs.

5.4 Other Key Performances: R-FPCB features flexible 3D wiring, high/low temperature resistance, foldability, anti-static interference, stable chemical properties and high reliability, adapting to smart health assistant applications, reducing product size/weight and improving functional integration.

6. R-FPCB Application Adaptability & Cost Trend

In addition to smart health assistants, R-FPCB is widely used in medical equipment, aerospace and digital products, especially suitable for miniaturized, high-reliability products. Although R-FPCB has higher initial costs, it is an ideal solution for smart health assistants requiring space and weight reduction; with industry maturity, its costs are gradually decreasing, enhancing cost-effectiveness.

7. Maxipcb’s Exclusive Advantages in R-FPCB for Smart Health Assistants

7.1 Strict Material Selection

Maxipcb selects materials tailored for smart health assistants: • Flexible Substrate: DuPont AP adhesive-free PI substrates, with excellent flexibility, electrical performance and heat resistance, avoiding inherent defects of conventional adhesives. • Rigid Substrate: PI resin materials laminated with P95 substrates/prepregs, preventing warpage caused by resin incompatibility. • Adhesive: No-flow prepregs to avoid glue overflow; raw materials are strictly verified to meet RoHS, high Tg and impedance requirements.

7.2 Precision Process Control

Maxipcb strictly controls core R-FPCB processes to ensure precision and reliability: • Inner Layer Pattern Transfer: Electrolytic cleaning to avoid substrate deformation, supporting line width/spacing of 0.1mm~0.15mm. • Multi-Layer Positioning: OPE positioning and X-ray drilling to eliminate alignment errors, meeting inter-layer registration requirements of 0.1mm~0.15mm. • Lamination & Drilling: Optimized process parameters, silicone rubber gaskets and high-speed drilling machines to ensure board flatness and hole quality.
