TG150 PCB | High-Tg 4-Layer Immersion Gold Circuit Board | 0.08mm Fine Line Specialist

TG150 PCB Circuit Board Introducere: Meeting the Thermal Challenge in Modern Electronics

In high-speed communications, auto, aerospațial, and advanced industrial controls, electronic devices face increasingly harsh operating environments. Elevated temperatures can cause standard PCB substrates (De ex., standard FR-4) to reach their glass transition, leading to softening, deformation, and critical performance loss, jeopardizing system reliability. Selecting a high-Tg printed circuit board is essential for ensuring long-term stability in these demanding applications.

1. Product Overview: What is a TG150 PCB?

O TG150 PCB is a printed circuit board fabricated using a laminate material with a glass transition temperature (TG) of 150°C. The Tg is a crucial metric for a PCB substrate’s thermal endurance. Compared to common TG130 PCB laminates, TG150 material maintains superior physical rigidity and stable electrical properties under high temperatures. UGPCB 4-layer TG150 circuit board combines this high-performance material with an Aur de imersiune (De acord) surface finish and supports 0.08mm fine-line circuitry şi 0.2mm micro-drilling, making it a high-reliability PCB multistrat solution for advanced applications.

2. Core Material and Enhanced Performance of TG150 PCB

• Material de bază: A high-performance epoxy or modified FR-4 formulation, specially engineered to consistently achieve a Tg of 150°C or higher.

• Key Performance Advantages (vs. TG130 PCBs):

  • Exceptional Thermal Stability: The increase from 130°C to 150°C Tg significantly enhances the board’s resistance to deformation at high temperatures, improving its ability to withstand high-temperature assembly processes like lead-free soldering.

  • Superior Moisture and Chemical Resistance: A denser molecular structure reduces moisture absorption in humid environments, minimizing losses in insulation resistance (IR) și integritatea semnalului, while offering better resistance to chemical exposure.

  • Improved Mechanical Strength and Dimensional Stability: High Tg PCBs exhibit lower Z-axis expansion coefficients and stronger bond strength during thermal cycling, reducing risks like via cracking and delamination.

  • Stable Electrical Characteristics: Constanta dielectrică (DK) şi factor de disipare (Df) remain more stable at elevated operating temperatures, ensuring higher signal integrity for PCB-uri de înaltă frecvență.
