4-Layer Rigid-Flex PCB Manufacturer – High Tg, 1.6หนา มม, ENIG+Gold Plating | UGPCB

1.UGPCB 4-Layer High Tg Rigid-Flex PCB ภาพรวมผลิตภัณฑ์: Redefining High-Reliability Interconnectivity

In modern high-end electronic design, traditional rigid แผงวงจรพิมพ์ (PCBS) are often limited by space and form factor, while Flexible PCBs (FPCS) may lack mechanical support. PCB แบบแข็ง เทคโนโลยี, an innovative การผลิต 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.

3. Design Essentials & Structure Analysis

Successful Rigid-Flex PCB design เป็นสิ่งสำคัญ. 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 (เช่น, copper-dielectric-core-dielectric-copper) to prevent warping under thermal stress.

3. ความเข้ากันได้ของวัสดุ: The selected Panasonic RF-777 material has matched Coefficients of Thermal Expansion (ซีทีอี) 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. วัสดุ & ผลงาน

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

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

  • ดีเคต่ำ (ค่าคงที่ไดอิเล็กตริก) & ฟ (ปัจจัยการกระจาย): Ensures signal integrity for PCB ความถี่สูง การใช้งาน.

  • Superior Dimensional Stability & Chemical Resistance: Guarantees long-term reliability.

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

  • เห็นด้วย: 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.
