Circuit Board HALT Testing Case Study
Customer Goal A customer approached DES looking to perform Highly Accelerated Life Testing (HALT) on a new circuit board design. DES and the customer agreed to test the circuit boards using DES’s traditional HALT test procedure which calls for hot/cold temperature steps followed by rapid temperature ramping, vibration steps and combined temperature and vibration stresses. HALT …
Rapid HALT – A Cost Effective Alternative to HALT
Rapid Highly Accelerated Life Testing or Rapid HALT is a reliability test method that is used to expose product weaknesses. A Rapid HALT procedure is a modification of a Classical HALT procedure. For more information about Classical HALT procedures, refer to the following blog articles: What is HALT Highly Accelerated Life Testing and why perform …

Accelerated Life Product Reliability Testing of a Carrying Handle
A leading medical technology company contracted DES to perform Product Reliability Testing of a carrying handle. A sample of the test can be seen below and in our video library. The carrying handle had to be pulled, released, rotated and subjected to a sizable lifting force, approximately 20,000 times during its life time. DES has …

Constant Temperature Accelerated Life Testing using the Arrhenius Relationship
When products are mainly exposed to temperature stresses in the field, Constant Temperature Accelerated Life Testing is used to simulate product life. Products can be tested at temperatures above their normal use temperature during Constant Temperature Accelerated Life Testing in order to accelerate aging. Defects or failure modes that would show up after many years …
