4-레이어 Rigid-Flex PCB 제조업체 – 높은 Tg, 1.6mm 두께, ENIG+금도금 | UGPCB

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

In modern high-end electronic design, traditional rigid 인쇄 회로 기판 (PCB) are often limited by space and form factor, while Flexible PCBs (FPC) may lack mechanical support. 리지드 플렉스 PCB 기술, an innovative PCB 제조 해결책, 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. 디자인 필수사항 & Structure Analysis

Successful Rigid-Flex PCB design 중요합니다. 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 (예를 들어, copper-dielectric-core-dielectric-copper) to prevent warping under thermal stress.

3. 재료 호환성: 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.
