Blue solder mask PCB

Overview of the Blue Solder Mask PCB

The Blue Solder Mask PCB is a high-density, multilayer printed circuit board (プリント基板) designed for digital applications requiring mass production. This PCB is ideal for complex electronic systems that need to manage high power and signal integrity.

What is a Blue Solder Mask PCB?

A Blue Solder Mask PCB is a printed circuit board (プリント基板) with a blue solder mask layer, which is used to protect the copper traces from oxidation and short circuits. The blue color makes it easy to distinguish different components and layers during assembly and inspection.

Design Requirements

The design requirements for a Blue Solder Mask PCB are stringent to ensure its performance and reliability:

• 材料: FR4, chosen for its excellent electrical and thermal properties.
• レイヤー数: 6 layers to accommodate complex and dense circuit designs.
• 色: Blue/White for easy identification and aesthetic appeal.
• 仕上がり厚さ: 1.2mm to provide structural integrity and durability.
• 銅の厚さ: 1/0.5/0.5/0.5/0.5/1 OZ to ensure adequate conductivity and heat dissipation.
• 表面処理: Immersion Gold to enhance solderability and corrosion resistance.
• Minimum Trace and Space: 4ミル(0.1mm) to support fine circuit patterns.

How Does It Work?

The Blue Solder Mask PCB works by providing a platform for various electronic components to be interconnected through conductive pathways. These pathways, or traces, are made of copper and are etched onto the board. The blue solder mask layer protects the copper traces from environmental factors, while the immersion gold surface treatment ensures that these traces remain conductive and resistant to corrosion.
