Full Description Provides specific test methods to evaluate the performance and reliability of surface mount solder attachments of electronic assemblies. Establishes levels of performance and reliability of the solder attachments of surface mount devices to rigid, flexible and rigid-flex circuit structures.

Tested per IPC A by. Reza Ghaffarian, Ph. Representative temperature profile for thermal cycle test conditions. Thermal Cycling is usually performed at a transition rate of less than or equal to 20C per minute usually 10 to 14C per minute to avoid thermal shock with cycles per hour. Common test specifications include:.

Whether you are trying to implement a new solder type or new component types, solder joint reliability testing is essential in providing confidence ipf your product will perform within its intended operating limits.
