TG150 PCB Circuit Board Introduction: Meeting the Thermal Challenge in Modern Electronics
In high-speed communications, automobile, aérospatial, and advanced industrial controls, electronic devices face increasingly harsh operating environments. Elevated temperatures can cause standard PCB substrates (par ex., standard FR-4) to reach their glass transition, leading to softening, deformation, and critical performance loss, jeopardizing system reliability. Selecting a haute Tg circuit imprimé is essential for ensuring long-term stability in these demanding applications.

1. Présentation du produit: What is a TG150 PCB?
UN TG150 PCB is a circuit imprimé 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 Immersion Or (ACCEPTER) finition de surface and supports 0.08mm fine-line circuitry et 0.2mm micro-drilling, making it a high-reliability carte PCB multicouche solution for advanced applications.
2. Core Material and Enhanced Performance of TG150 PCB
-
Matériau de base: A high-performance epoxy or modified FR-4 formulation, specially engineered to consistently achieve a Tg of 150°C or higher.
-
Key Performance Advantages (contre. 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) et l'intégrité du signal, 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: Constante diélectrique (Ne sait pas) et facteur de dissipation (Df) remain more stable at elevated operating temperatures, ensuring higher signal integrity for PCB haute fréquence.

4. Manufacturing Process and Quality Control
UGPCB TG150 PCB manufacturing process strictly adheres to international standards like IPC-6012 (Qualification and Performance Specification for Rigid PCBs). The process includes:
Material Preparation → Inner Layer Imaging → Etching → Lamination → Drilling (0.2mm) → Desmear & Plating → Outer Layer Imaging → Pattern Plating → Etching → Solder Mask Application → ENIG Surface Finish → Routing → Electrical Testing → Final Inspection.
At each stage, we employ advanced equipment (par ex., LDI imaging, Inspection de la zone d'intérêt) and rigorous reliability testing (par ex., contrainte thermique, ionic contamination) to ensure the quality of every high-Tg circuit board.
