6-Layer PCB Stackup (370HR)
The 6-layer stackup of this PCB (370HR) has a total thickness of 62.0 mil. It starts with a Signal layer (Layer 1, Filename: Top) with a thickness of 1.4 mil, followed by a 6.0 mil insulation layer. Next is a Plane layer (Layer 2, Filename: GND) with a thickness of 1.4 mil, accompanied by a 6.0 mil insulation layer. Then comes a Signal layer (Layer 3, Filename: SIG1) with a thickness of 1.4 mil, followed by a 29.6 mil insulation layer. After that is a Signal layer (Layer 4, Filename: SIG2) with a thickness of 1.4 mil, along with a 6.0 mil insulation layer. Next is a Plane layer (Layer 5, Filename: PWR) with a thickness of 1.4 mil, followed by a 6.0 mil insulation layer. Finally, it ends with a Signal layer (Layer 6, Filename: Bottom) with a thickness of 1.4 mil.
Artwork, Standard & Availability
Type of artwork supplied: Gerber RS-274-X
Accepted standard: IPC-Class-2
Availability: worldwide
- Material Advantages: 370HR laminates boast a 180°C Tg, 340°C Td, and low CTE (45ppm/°C Z-axis pre-Tg), delivering exceptional thermal resistance. They offer superior CAF resistance, 0.4W/MK thermal conductivity, and stable dielectric properties (DK 3.92-4.24; Df 0.015-0.025 across frequencies), outperforming traditional FR-4.
- Typical Applications: Ideal for computing/storage, consumer electronics, networking/communications, medical devices, industrial instrumentation, automotive/transportation, and aerospace/defense.
