Electrical Equipment Performance Testing

WHA generally conducts electrical equipment performance testing to support electrical failure investigations. The testing is designed to evaluate the conditions required to recreate failures (i.e., reconstruction testing) or determine the conditions that electrical equipment can tolerate without failure. Testing can also be used to determine the severity of a failure and evaluate factors that intensify the severity. WHA has conducted the following types of performance testing:

Fig. 1 - Poor solder joint fillet combined with strain lead to solder cracking.Fig. 2 - Careful potting and sectioning lead to the root cause of the solder joint cracking.

Fig. 3 - Identification of oxidation and corrosion byproducts accumulated on circuit board through SEM/EDS.Fig. 4 - Corrosion build up on connector due to fretting leads to high resistance connection and thermal damage.
