Introduction to Gold Finger Blind Hole PCB

The Gold Finger Blind Hole PCB is a specialized type of printed circuit board (tarjeta de circuito impreso) 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.

Aplicaciones

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.

Clasificación

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

Material

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

Performance

With trace/space dimensions of 4mil/4mil (0.1MM/0.1MM) and a minimum hole size of 0.2mm (8mil), 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.

Structure

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.

Características

Some key features of the Gold Finger Blind Hole PCB include:

  • High-density interconnect capability
  • Low contact resistance due to immersion gold finish
  • Durable and reliable construction with S1140 FR4 material
  • Compact design with gold fingers and blind holes

Proceso de producción

The production process for the Gold Finger Blind Hole PCB involves several steps, incluido:

  1. Material Preparation: Selecting the appropriate S1140 FR4 material and cutting it to size.
  2. Layer Stacking: Stacking the layers of the PCB with precise alignment.
  3. Copper Etching: Using chemical etching to create the desired circuit patterns on each layer.
  4. Via Drilling: Drilling blind and buried vias to create internal connections between layers.
  5. Plating: Applying copper plating to the vias and other exposed copper areas.
  6. Tratamiento superficial: Applying immersion gold to the surface of the PCB for improved conductivity and corrosion resistance.
  7. Assembly: Assembling the gold fingers onto the edge of the PCB for easy connectivity.

Use Cases

The Gold Finger Blind Hole PCB is ideal for use in computer components where space is limited and high-speed data transmission is required. Examples include motherboards, tarjetas graficas, and other high-performance computing devices.
