Gold Finger Blind Hole PCB

Introduction to Gold Finger Blind Hole PCB

The Gold Finger Blind Hole PCB is a specialized type of printed circuit board (печатная плата) that features gold-plated fingers and blind holes. This design allows for enhanced connectivity and compact integration within electronic devices.

Product Overview

The Gold Finger Blind Hole PCB is constructed using high-quality S1140 FR4 material, ensuring durability and excellent electrical performance. It consists of four layers, with a copper thickness of 1OZ and a finished thickness of 1.2mm. The surface treatment involves immersion gold, which provides excellent conductivity and corrosion resistance.

Приложения

This type of PCB is primarily used in computer components, where high-speed data transmission and reliable connections are crucial. The gold fingers allow for easy plugging and unplugging, while the blind holes facilitate internal connections without the need for through-hole components.

Классификация

The Gold Finger Blind Hole PCB can be classified based on its layer count, copper thickness, and special processes such as blind and buried vias, as well as the presence of gold fingers and blind holes.

Материал

The base material for this PCB is S1140 FR4, a flame-retardant glass-epoxy laminate that offers excellent thermal stability and mechanical strength.

Производительность

With trace/space dimensions of 4mil/4mil (0.1MM/0.1MM) and a minimum hole size of 0.2mm (8мил), the Gold Finger Blind Hole PCB is designed for high-density interconnect applications. The immersion gold finish ensures low contact resistance and long-term reliability.

Структура

The PCB consists of four layers, with blind and buried vias allowing for complex routing between layers without the need for through-hole components. The gold fingers provide an edge connector interface for easy integration into larger systems.
