A 2 Layer 1.6mm ENIG PCB Surface Finish refers to a specific type of printed circuit board (PCB) construction and finishing process. Here’s a breakdown of its key characteristics:
-
2 Layer: This PCB has two conductive copper layers, typically one on the top and one on the bottom, separated by an insulating substrate.
-
1.6mm: This is the total thickness of the PCB, which is a standard size offering a good balance between durability and flexibility.
-
ENIG (Electroless Nickel Immersion Gold): This is the surface finish applied to the exposed copper traces and pads. It involves depositing a thin layer of nickel, followed by an even thinner layer of gold.
ENIG offers several advantages:
- Excellent surface planarity, ideal for fine-pitch components
- Good solderability and extended shelf life
- Suitable for wire bonding
- Corrosion resistance
- Compatible with lead-free soldering
This combination is widely used in various electronics applications, offering a good balance between performance, reliability, and cost-effectiveness.
