In which class would a product with high performance requirements fall under according to IPC-A-610?

A product with high performance requirements falls under Class 3 according to IPC-A-610. This classification is specifically designed for products where performance, reliability, and extended life are critical. Class 3 encompasses applications such as aerospace, medical devices, and military equipment, where the functionality of the assembly must meet stringent criteria and perform reliably under adverse conditions.

In Class 3, the acceptable quality levels are the highest compared to Class 1 and Class 2. Class 1 is aimed at general electronic products, and Class 2 covers dedicated service electronic products with a moderate level of performance needed. Class 4 is often associated with high-reliability applications but may not be officially recognized within the typical IPC classifications. Overall, Class 3 is where high-performance standards are established, making it the appropriate choice for products with demanding requirements.
