Understanding IPC Class 2 Standard for Copper in Hole Wall and Our 20µm Capability

In PCB (Printed Circuit Board) manufacturing, the quality of copper plating in the hole walls is crucial for ensuring proper electrical conductivity and mechanical stability. The IPC Class 2 standard outlines the minimum copper thickness required in the hole walls to guarantee the reliability and performance of the circuit board. According to this standard, the copper thickness in the hole walls must meet certain criteria to ensure the board functions under normal conditions with acceptable durability.

IPC Class 2 specifically requires a minimum copper plating thickness of 12µm in the hole walls, ensuring that the board can handle routine operational stresses. This standard is typically used for consumer electronics where reliability is important but extreme durability is not as critical as in high-end applications.

However, in our manufacturing process, we go beyond the typical industry requirements. While we adhere to the IPC Class 2 standard, our capability allows us to produce PCBs with a minimum of 20µm copper thickness in the hole walls. This is a significant enhancement, providing superior electrical performance and increased durability. Our commitment to high-quality manufacturing ensures that the copper layer is consistently applied at this level.

To maintain the integrity of our products, we randomly check the copper thickness during production. This random testing ensures that each batch meets the desired specifications and that we consistently deliver products with the required copper thickness. By implementing this rigorous quality control process, we can guarantee that our PCBs not only meet IPC Class 2 standards but exceed them, providing enhanced performance and reliability for more demanding applications.

In conclusion, while IPC Class 2 sets the standard for copper in hole walls, our capability of achieving a minimum of 20µm copper thickness adds an extra layer of quality and reliability. This capability, combined with our random testing approach, ensures that we deliver the highest-performing PCBs to our customers.
