Understanding PCB Stacking Structure: A Comprehensive Guide
3. Insulation Layers
Insulation layers, commonly made from materials such as polyimide or FR-4, are positioned between the conductive layers. Their primary function is to provide electrical isolation, preventing short circuits and signal interference between layers. The quality of the insulation layers directly affects the PCB’s electrical performance, especially in high-frequency or high-density applications.
4. Solder Mask Layer
The outermost layer of the PCB is the solder mask layer, typically green, which protects the board from solder short circuits and environmental damage. This layer enhances soldering quality by ensuring solder adheres only to the required pads, reducing the risk of soldering defects like cold solder joints and solder bridges.
5. Silkscreen Layer
In addition to the primary layers, many PCBs include a silkscreen layer. This layer is used for printing component labels, numbers, and other essential information on the board. It aids in proper component placement during assembly and provides valuable reference for maintenance and repair.

PCB Cross-Section Inspection Project: Comprehensive Understanding and Defect Identification
Interlayer Connections: Examine the state of interlayer connections to check for poor connectivity or short circuits.
Line Width and Thickness: Measure the width and thickness of the lines to ensure they meet design specifications. Lines that are too wide or too thin can impact current conduction performance.
Hole Quality: Inspect the size and position of drilled holes, and ensure the walls are smooth and free from cracks. Hole issues can lead to poor electrical connections or insufficient mechanical strength.
Material Consistency: Assess the consistency of PCB materials, including the thickness and uniformity of insulation materials. Inconsistent materials can cause fluctuations in circuit board performance.
How to Identify Defective Products:
Through cross-section inspection, defective products can be identified based on the following characteristics:
Peeling or Delamination: Layer delamination usually indicates the use of substandard adhesives or process issues during production.
Copper Foil Peel-Off: Copper foil detachment may be due to improper temperature control or material quality issues during production.
Pad Damage: Pad damage is typically caused by improper handling or material defects during manufacturing.
Hole Issues: Inaccurate or defective holes can affect the functionality and reliability of the circuit board.
Through comprehensive cross-section inspection, we can promptly detect and correct these issues, ensuring the quality and reliability of PCB products to meet high customer standards. Accurate inspection not only enhances product performance but also reduces later repair and maintenance costs, providing customers with the highest quality circuit board solutions.
