Leslie: Product screens and tests of prototypes and test vehicles should be tailored for the specific goal and product. I caution your use of equations and test condition information without specific use environments and design conditions. Lawyer:

HALT is an approach to stimulate a failure till its existence. It is mainly used during product design and development phase. Traditional tests are mainly used to prove "no" failure but HALT is to make failure for information to improve in design of

Conformal Coat peeling

We doubt that HASS has much to do with your conformal coat peeling. Sure, poor wicking [low surface energy] could cause the issue that you see. Here are links to a couple of good [no formulas or differential equations] articles on surface energy: * h

Thermal fatigue of solder joints

Electronics Forum | Thu Oct 26 03:20:13 EDT 2000 | heccles

What would be a typical thermal test regime to verify the quality of solder joints for high specification applications - what would be the specific benefits of utilizing a "HALT" process over other traditional test techniques ?

Checking your reflow ovens ?

We used to do this, but we dont any more. Never found something with the Mole. We have had 2 blowers come to a halt due to stuck bearings, but that was easely spotted without a check. (Temperature alarm and Huge whining noise)

8221 controller on an old axial

try "halt" your EMI and check if the @ appear on screan. If yes, type G or P to re-start the system. If NO, make sure 5VDC is present. V2 controller really a tricky one.

if you have not turned the halt switch down then back up you can sometimes get a restart using 0(zero)G and enter. If that does not work you will have to load the exec.
