This double-sided FR4 TG170 PCB is a versatile and cost-effective solution. It suits applications from industrial control systems to consumer electronics and medical devices. With a 1.6mm thickness, 1오즈 구리 층, and a lead-free HAL surface finish, this PCB balances mechanical strength, 전기 신뢰성, 및 환경 준수. Therefore, it is ideal for mid-complexity electronics requiring consistent performance at scale.

Superior Material and Thermal Stability

Constructed from FR4 material with a high glass transition temperature (tg) 170 ° C, this PCB offers enhanced thermal stability. Compared to standard FR4 (TG130 ° C), it performs better in environments with temperature fluctuations between -20°C and +80°C. This advantage ensures reliable operation. The double-sided design also allows engineers to route complex circuits efficiently. Dual-layer signal traces and copper pours for power and ground planes reduce electromagnetic interference (에미) and improve signal integrity. As a result, it supports low-to-medium-speed applications such as microcontrollers, 센서 인터페이스, and communication modules.

Key Features for High-Quality PCB Manufacturing

• 무연 hal 표면 마감: This finish is RoHS and REACH compliant. It provides excellent solderability and good corrosion resistance. Additionally, it suits both manual and automated assembly, especially in applications requiring frequent rework.

• 1OZ Copper Layers: With 35μm thickness, the copper layers support moderate current loads up to 8A per wide trace. They enable fine-line routing with minimum line/space of 100μm/100μm. This balances power delivery and high component density.

• 녹색 LPI 솔더 마스크: The solder mask enhances visual clarity for assembly and rework. Moreover, it resists common industrial contaminants like oils, solvents, 그리고 청소제. Therefore, it is ideal for harsh environments such as manufacturing plants or outdoor equipment.

Rigorous Manufacturing and Quality Control

The PCB undergoes precise fabrication to guarantee quality and reliability:

• High-precision mechanical drilling with ±50μm tolerance ensures accurate vias.

• Plated Through Holes (PTH) receive 25-35μm copper coating for strong inter-layer connections.

• UV lithography defines fine circuit patterns with 100μm resolution.
