What maximum percentage of deformation is allowed on leads for them to remain acceptable?

• A. 5%
• B. 10%
• C. 15%
• D. 20%

Answer: (B)

The maximum percentage of deformation allowed on leads for them to remain acceptable in accordance with the IPC J-STD-001 standards is indeed 10%. This standard ensures that the leads maintain their integrity and functionality after being subjected to various mechanical stresses during handling and assembly. Exceeding this limit could compromise the electrical connection, mechanical performance, or overall reliability of the component in its application. The 10% threshold balances the need for durability during assembly with the requirements for maintaining proper electrical and mechanical properties. Therefore, it serves as a critical guideline for manufacturers and assemblers to follow, ensuring quality control in soldered electrical and electronic assemblies.
