Gary: Allow expand on this topic a bit. Back in the gray skied past when people wore calculators on their belts, rather than pagers n Palms, and didn�t drink California spill, they used HASS that you mentioned and HALT (Highly Accelerated Life Test

I'd like to side with Chunks on this one mainly as I come from a component manufacturing background, but also because your arguement comes from the perspective of someone who is an engineering consultant for a company that specialises in HASS & HALT.

Try looking at Chart Industries. They offer HASS/HALT chambers that are capable of reaching the paramaters that you are looking for. Will require a nitrogen supply for the cooling end.We had a 3000gal tank of liquid nitrogen to feed two chambers.

We have a couple of Qualmark HALT/HASS chambers here. Never had a problem with either.

Every failure analysis study I've seen, (and quite a few by now) showes Pb Free failing in about half the time or cycles as Sn/Pb. HALT and HASS testing shows reality- run way from a Pb Free product other than a camcorder, etc...

We use the 3748. We picked it many moons ago after doing product HALT & HASS testing. Basically the run of the mill hotmelts didn't hold up as well under the conditions our equipment lives in. (We do a lot of MIL,Aero & Industrial motor/actuator driv

You know the products operating limits,and these have been pushed out during development using Highly Accelerated Life Testing (HALT) 2> Proof of Screen has been conducted to ensure that wear out failures are not induced by the screen If the above

60G are common, as are vibration events of >1.5Grms. And drop heights are just outrageous, old billy throwing your new server off the truck doesn't care too much about the glass house theory, but loves to throw anything that he can lift... say he cra

Gary: Regular FR-4 will HASS. HASS has largely fallen from favor, because: * Process is difficult to control, so not to strip the life from components * Failures under HASS have nothing to do in use failures. If you insist on continuing with this,
