When we think of HALT, we think of HALT Chambers and the stresses they provide – cold temperature, hot temperature, rapid thermal transitions, vibration stress, and combined thermal and vibration environments.
We need to expand our thinking of HALT into meaning any stress that can accelerate finding defects (in other words, to find design weaknesses before your customers find them).
Many other stresses can be used for HALT including: ESD, drop testing, bend testing, water ingress testing, and more. In this presentation, we will explore some of the HALT stresses we can apply in addition to temperature and vibration.
We will also explore some misuses of typical HALT chambers and how HALT practitioners believe just because they are using HALT chambers, they think they are performing HALT. If you are not performing HALT with the intention of discovering and expanding product margins, you are not performing HALT no matter what equipment you are using. In this presentation, we will explore some of the common errors HALT practitioners make that takes them off the path of performing HALT.
