Acceptance criteria for PCBA
What are the main differences between IPC-A-610 Level 2 and Level 3

IPC-A-610 is the most widely used acceptance standard for printed circuit board components. IPC-A-610 defines visual acceptance criteria for three types of electronic products (Class 1, Class 2, and Class 3). IPC-A-610 Class I is no longer commonly used. IPC-A-610 Class 2 and IPC-A-610 Class 3 are the two most commonly used IPC-A-610 acceptance standards in the industry today. Therefore, it is crucial to understand the differences between IPC-A-610 Class 2 and Class 3 when deciding which standard to adopt. IPC-A-610 presents a practical and comprehensive set of acceptance criteria to ensure that electronic products meet the required quality standards. In addition, IPC-A-610 Class 2 and Class 3 provide different levels of acceptance criteria. Therefore, they are suitable for various applications.

industry Specialized in serving electronic products such as consumer electronics, laptops, communications, controls, lighting Products with high reliability requirements, such as automotive, medical, military, avionics, and life support systems
Inspection standards Reduce the acceptance of standard solder joints, material surface treatment, terminals, connections, and mechanical integrity High standard solder joint acceptance, material surface treatment, terminals, connections, mechanical integrity

Remembering the differences between IPC-A-610 Level 2 and Level 3 is crucial for the successful implementation of IPC standards. Choosing between IPC-A-610 Level 2 and Level 3 requires consideration of the application type and the required levels of reliability, appearance, performance, etc.
