10 Characteristics of PCB Circuit Board

Time:2023-12-19Views:


Hole wall copper thickness: A 25 micron hole wall copper thickness effectively enhances the reliability of PCB boards and improves the Z-axis expansion resistance.

No welding/patching repair: Perfect for no welding repair and open circuit patching repair, which can effectively ensure the reliability and safety of circuit boards.

IPC specifications: For some manufacturers of high-end and high-quality PCB circuit boards, exceeding IPC specifications for cleanliness can not only improve customer satisfaction and trust, but also gain a certain influence in the industry.

Service life: Strictly control the surface treatment of each type of PCB circuit board to ensure its solderability and reliability meet industry standards, and reduce the risk of moisture intrusion.

Substrate: According to the company's positioning standards, select internationally renowned boards to improve product reliability and known performance.

Ink: Ensure that the solder mask material used complies with the IPC-SM-840ClassT standard, ensuring that the ink color is bright and glossy under high temperature baking.

Tolerance: Strictly control various tolerances of PCB boards, such as board thickness tolerance, line width and moment tolerance, aperture tolerance, etc. Strictly controlling various tolerances can greatly improve product quality.

Plug hole depth requirement: High quality circuit boards have strict requirements for plug hole depth and no minor issues are allowed.

Confirm each order information: NCAB implements specific approval and ordering procedures for each purchase order to ensure that each PCB information sent matches the file name, and repeatedly verifies to avoid problems.
