Q8, PMS SEND TO THOSE WITH ISSUES BLF soda can light

Only 10-60 years? :smiling_imp: :smiley: Maybe change a resister to get that number up a bit? (sorry, I couldn’t resist[er])

135 µA = 0.135 mA yes? Sounds like DEL and Tom got pretty much the same numbers.

tocirahl, that’s my understanding as well

Yep, just a very slight bit of difference.

I just spent 350 dollars online, and not a dime of those was for the Q8 :wink: will have to resort to throwing wads of cash at my computer screen to get things going.

Those drain numbers do vary with cell voltage. My number was taken with a fairly fresh cell, the worst case.

For electric/electronic stuff these metric prefixes are commonly used:

  • x1000000 - mega or M
  • x1000 - kilo or k
  • /1000 - milli or m
  • /1000000 - micro or µ
  • /1000000000 - nano or n
  • /1000000000000 - pico or p

So 0.14 mA would correctly be the same as 140 µA. mA is just easier to type :slight_smile: .

Yesterday I got my LG HG2 battery pack dedicated for the Q8 :crown:

Just checked mine again.
It has also the delamination problem. Doesn’t look as bad as the others but it is a problem.

To me it looks like the compleet ‘pcb’ part is coming off of the copper.

I’m hoping I’m not to late. Please add me to the list … thank you!!

I am so glad you guys are on top of things and have caught/noticed/seen this delamination issue so that it can be addressed & corrected before production.

Depending on how bad & widespread it is…. this was a potential Q8 disaster in the making. :person_facepalming:

Hat’s off to you all for being on top of things. :+1:
.
:slight_smile:

Yes will update list later :wink:

Hmm Thijsco too?
Hopefully this is a prototype mcpcb …

Is there such a thing as one off / hand made / hand etched MCPCB’s?

I guess that’s why multiple proto’s where asked for… If it’s a proto board then the issue could be resolved easy. If not it might be a good idea that the team looks for a mpcb producer? Although I don’t think I ever heard of thorfire lights having this issue or they never designed a light pulling 20A in stock form.

Has any manufacturer EVER made a flashlight that pulls 20A in stock form?

Touché as the french say: you have a point there.

Is there an accelerated-aging test to detect this kind of problem?
I’d guess repeated heat-cycling would provoke it, if it’s going to happen.
That’s a fairly common method of testing for potential failures, isn’t it?
Someone who knows something, please comment ….

That’s one of those QA issues — think of everything that could possibly go wrong, and fix the production
and one of those QC issues — do tests of samples of the produced work to find patterns of errors.

My impression was:
It may be a situation where these mcpcb were made on a older machine that doesn’t get much use anymore. It’s a good machine to use for small batches and prototype stuff, but when full production starts, the newer, faster, fully automated mcpcb machine will be used. That’s the thought that popped into my head.

I’m sure it wasn’t hand made and hand etched, etc…

I’m actually curious if Thorfire makes them or they buy them from another company.

Either way, either it’s a problem they already know happens, and know how to watch for, or it’s one they’ve never seen happen and need to take into account.

Googled: thorfire delamination
Found a BLF hit at What did you mod today? - #2893 by zak.wilson which I think refers to some other flashlight, not to a Thorfire:

Someone with more patience could look through the rest of the Google hits or refine a search.
Or, of course, ask Thorfire if they know about this …

If it is a “prototype” MCPCB, used only in these Q8 Prototype 3’s ; that should be easy enough to verify.

If, on the other hand; it is the real deal that was supposed to be used in production…… it is a darn good thing the problem was recognized before production so it can be addressed & FIXED.

Otherwise, as I already said; depending on how bad & widespread the problem is…. it could have spelled a Q8 disaster.

As it stands right now all #3 Prototypes have been received & if I remember correctly, three have had MCPCB problems.

PROTOTYPES ARRIVING
in order of arrival:

  • Tom E……………… X
  • MRsDNF
  • The Miller
  • Djozz
  • Thijsco……………. X
  • Pilotdog68
  • DEL…………………… X

X = MCPCB problem

I googled for thorfire pcb delamination . Only a handful of results turned up but none pertaining to Thorfire. Seems like delamination has to do with moisture being trapped inside the pcb but what do I know from a simple google search.
