4-Layer Rigid-Flex PCB Manufacturer – High Tg, 1.6mm di spessore, ENIG+Gold Plating | UGPCB

1.UGPCB 4-Layer High Tg Rigid-Flex PCB Panoramica del prodotto: Redefining High-Reliability Interconnectivity

In modern high-end electronic design, traditional rigid Circuiti stampati (PCB) are often limited by space and form factor, while Flexible PCBs (FPCS) may lack mechanical support. PCB rigido-flessibile tecnologia, an innovative Produzione di PCB solution, perfectly merges the stability of rigid boards with the bendability of flexible circuits. UGPCB 4-Layer High Tg Rigid-Flex PCB, with its precise lamination structure, superior material selection, and demanding surface finish, stands as the ideal PCB solution for complex 3D spatial layouts and harsh operating environments.

2. Scientific Classification & Core Parameters

• Scientific Classification: Per Standard IPC and industry norms, this product is accurately classified as a 4-Layer High Thermal Reliability Rigid-Flex Printed Circuit Board.

• Core Parameters:

  • Layer Construction: 4 Strati (4PCB rigido-flessibile)

  • Spessore della scheda: 1.60mm (in rigid areas, including dielectrics and copper)

  • Materiale di base: Panasonic RF-777 (35/50µm copper)

  • Finitura superficiale: Essere d'accordo (Oro per immersione in nichel chimico) 3µ” + Selective Electroplated Hard Gold 30µ”

  • Dimensioni: 126mm * 80mm

3. Design Essentials & Structure Analysis

Successful Rigid-Flex PCB design è fondamentale. This product is designed adhering to these key points:

1. Rigid-to-Flex Transition Zone Design: Bend areas are meticulously simulated, avoiding right and acute angles. Smooth curved traces are implemented to eliminate stress concentration points, a cornerstone of high-reliability PCB design.

2. Stack-up Symmetry: Rigid sections employ a symmetrical lamination stack-up (per esempio., copper-dielectric-core-dielectric-copper) to prevent warping under thermal stress.

3. Compatibilità materiale: The selected Panasonic RF-777 material has matched Coefficients of Thermal Expansion (Cte) in both rigid and flexible zones, ensuring robust bonding at the interfaces.

Structural Feature: The board is constructed by laminating two rigid outer sections with a multilayer structure containing flexible inner layers, enabling electrical interconnection in three-dimensional space.

4. Materiali & Prestazione

• Core Material: Panasonic RF-777. This is a high-performance laminate specifically optimized for Rigid-Flex PCB fabrication.

  • High Glass Transition Temperature (Tg): Provides excellent thermal stability, maintaining mechanical and electrical properties during high-temperature soldering (per esempio., lead-free reflow) and in high-temperature operating environments.

  • Low Dk (Costante dielettrica) & Df (Fattore di dissipazione): Ensures signal integrity for PCB ad alta frequenza applicazioni.

  • Superior Dimensional Stability & Resistenza chimica: Guarantees long-term reliability.

• Finitura superficiale: ENIG 3µ” + Electroplated Hard Gold 30µ”. This combination is a key differentiator.

  • Essere d'accordo: Provides a flat, highly solderable surface finish across the entire board, suitable for fine-pitch component assembly.

  • Electroplated Hard Gold: Applied selectively to connector fingers or areas subject to frequent insertion/withdrawal or friction, the 30µ” hard gold layer dramatically increases wear resistance, oxidation resistance, and contact reliability, extending connector lifecycle.
