Engineers and product developers face increasing pressure to miniaturise components without sacrificing performance. A 12-Layer HDI PCB provides the structural complexity required for compact, high-speed electronic devices. Utilising a precise 3+N+3 stackup, this HDI PCB enables dense routing and reliable signal transmission for demanding hardware architectures. It is the definitive choice for projects requiring strict dimensional tolerances and advanced thermal management.
-
Stackup Architecture: 3+N+3 sequential lamination supports complex via-in-pad, blind, and buried microvia structures.
-
Material Specifications: Manufactured with advanced FR4 and halogen-free laminates to ensure exceptional thermal stability.
-
Routing Density: Accommodates fine pitch BGA and high pin-count components without routing congestion.
-
Signal Integrity: Precision controlled impedance routing minimises cross-talk and reflection in high-speed applications.
-
Manufacturing Standards: IPC Class 2 and Class 3 compliance ensures robust performance in critical operational environments.
The 3+N+3 stackup design suits industries requiring robust functionality within constrained footprints:
-
Telecommunications infrastructure and 5G networking equipment
-
Advanced medical diagnostics and clinical imaging devices
-
Aerospace avionics and compact flight control systems
-
High-performance computing and industrial automation controllers
