The High-Tg HDI PCB Stackup delivers the thermal resilience and routing density required for modern, miniaturised electronics. Utilising high-temperature glass transition (High-Tg) substrate materials, this advanced build-up board maintains its structural and mechanical integrity during intense thermal cycling. It is purpose-built for complex layouts that demand sequential laminations, fine lines, and microvia technology to support high-pin-count components.
Key Features
-
Thermal Stability: Utilises High-Tg materials ($\ge \text{170}^\circ\text{C}$) to resist delamination and blistering during lead-free soldering processes.
-
Advanced HDI PCB Architecture: Supports complex laser-drilled microvias, stacked vias, and buried vias for maximum routing density.
-
Precision Control: Fine line and space capabilities down to 3/3 mil ($75\ \mu\text{m}$) for high-speed signal routing.
-
Controlled Impedance: Tailored stackup configurations to meet exact differential and single-ended impedance specifications.
-
Quality Standards: Manufactured in compliance with IPC-A-600 Class 2 or Class 3 standards for high-reliability electronics.
Applications
-
Aerospace & Defence: Rugged avionics, radar systems, and flight control computers.
-
Automotive Electronics: Advanced driver-assistance systems (ADAS), engine control units (ECUs), and electric vehicle powertrain management.
-
Telecommunications: High-speed routers, switches, 5G base stations, and network infrastructure.
-
Medical Devices: High-resolution imaging equipment, patient monitoring systems, and implantable device controllers.
