What is a 10Layers ENIG Board?

A 10-layer ENIG (Electroless Nickel Immersion Gold) board is an advanced multilayer printed circuit board (PCB) with ten layers of conductive material, typically copper, separated by insulating layers. The “CONCORDAR” refers to the surface treatment applied to the copper traces, which involves electroless nickel and immersion gold plating. This type of PCB is designed for high-density and complex electronic applications.

Design Requirements

Designing a 10-layer ENIG board involves several key considerations:

  • Material: Made from TU-768, a high-performance composite material known for its excellent electrical properties and durability.
  • Contagem de camadas: Consists of ten layers, allowing for intricate and dense circuit designs.
  • Espessura do Cobre: Ranges from 2OZ to 3OZ, providing robust conductivity for high-power applications.
  • Tratamento de superfície: Features immersion gold plating, which offers excellent solderability and corrosion resistance.
  • Trace and Space: Minimum trace and space are set at 3mil (0.075milímetros), enabling fine details in the circuit design.

How Does it Work?

The 10-layer ENIG board functions by providing multiple layers of conductive pathways, separated by insulating layers, to interconnect electronic components. The immersion gold surface treatment ensures reliable soldering and long-term protection against oxidation and wear.
