Delserro Engineering Solutions (DES) was honored to be featured in a recent article discussing the capabilities of engineering testing companies. The article highlighted the benefits, in terms of both design and cost, of adequately testing designs, preferably as early in the process as possible. It also discussed the ins and outs of partnering effectively with a reliability testing facility.
The goal of this article was to teach product developers how to get the most bang for their testing buck; a goal that aligns perfectly with DES’s philosophy. No matter what your testing needs are, be they HALT, HASS, or other environmental or stress tests, DES is able to help you design and implement the most comprehensive and accurate test possible. As always, our client’s success is the source of our satisfaction.

Product reliability is essential to success in today’s competitive global market. HALT and HASS are intensive methods used to expose and then improve design and process weaknesses. HALT and HASS are faster, less expensive and more accurate than traditional testing techniques. HALT and HASS are proven processes used to lower product development and manufacturing costs, compress time to market, reduce warranty costs, improve customer satisfaction, gain market share and increase profits. Some companies have reported savings in the millions after using HALT and HASS.
HALT and HASS can accelerate a product’s aging process from actual months into test minutes much faster than traditional testing!

This article discusses an abbreviated technique that uses the tools of HALT to expose hard-to-find defects in products returned by customers, written by Gary Delserro and published in Evaluation Engineering Magazine. Click on the link to view the article in PDF, Exposing Hard to Find Defects.
How many times have your customers returned products or circuit boards with reported defects that you can’t find? Every manufacturer experiences this situation at some time. Your customer reports a problem in your product and sends it back to you. You test the faulty product in your lab and the problem doesn’t occur. Sometimes you try to bend it or tap it against the table. You may even try heating it in a chamber or with a heat gun or using a freeze spray. Still the problem does not expose itself.
