Thermal Cycling is the most common method of testing Solder Joint Reliability.
Please allow 2 business days for us to review and process your order. Training Media Permissible Uses.
Per Ip, temperature extremes are based on the product category with the low temperature usually 25C below the glass transition temperature Tg of the printed circuit board material. This provides you with useful technical information for future designs, saving you time and money. The results from different test programs can be compared to provide an understanding of design requirements for adequate reliability.
Solder Joint Reliability | NTS
Whether you are trying to implement a new solder type or new component types, solder joint reliability testing is essential in providing confidence that your product will perform within its intended operating limits.
The electrical resistance is continuously monitored during testing using data loggers. See More See Less. Common ic specifications include:.
When used with IPC-SM, it provides an understanding of the physics of Ipv solder joint failure and an approximate means of relating performance tests results to the reliability of solder attachments in their use environments.
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. Provides specific test methods to evaluate the performance and reliability of surface mount solder attachments of electronic assemblies.
