Which statement is true regarding the validation of processes in soldered assemblies?

The statement that both major and minor changes have specified validation criteria is accurate. In the context of soldered assemblies, adherence to the IPC J-STD-001 standard mandates that any changes to the manufacturing process, regardless of the size or significance of the change, should undergo a validation process to ensure that product quality is maintained. This is essential because even seemingly minor changes can have unintended consequences on the soldering process, impacting the overall reliability and performance of the finished assembly.

The validation process helps to assure that the new processes or modifications to current processes are capable of consistently producing products that meet the required specifications. This proactive approach is critical in maintaining high standards in electronic manufacturing environments, ensuring compliance with established guidelines. Thus, both major and minor changes carry a responsibility for validation, reinforcing the principle that quality assurance is a continuous aspect of manufacturing processes.
