Got my 1st 2 V5 Flex's today and the mail gorilla broke abt 1/3 of the top bobbin off one of the 3.3uH coils. :yabbmad:
I sent them a message abt it. If it effects it working I told them they could just send another choke. I can replace it. Be nice if they sent one....just the choke. Instead of "3R3", it looks like 3R and 2 dashes............broke it to the core and the coil is exposed. Hope it didn't crack the core. Kinda doubt it.
Waited so long for them to be available.....sigh
The pieces are in the bag it came in. Epic Mail Fail

Got any pics. It is such a buzz kill when you are excited because you just got the package you have been waiting for and something is either broke or you got the wrong thing.

I imagine they will want a pic. So, I'll take a few tomorrow and post it then. Not a devastating thing.........it was just my 1st 2.
It was in an antistatic zip lock bag in a bubble envelope. The bobbins end is pretty thin so it wouldnt take a lot as brittle as ferrite is.
Maybe the mail lady is mad at me after I asked her for a pictures of her holding my laser.:crackup:
EDIT:
Already received an email from Steve abt the broken 3.3uH coil. His reply was "No don't risking frying a diode, I'll ship you another one." How's that for customer service? I don't know if he means another driver or just a coil. A coil is all I asked for "if it was going to effect the operation". SMD soldering is nothing new to me and I figured if they had a bad drive there, pull the coil and that's fine by me.
So, as an "FYI" this should be something to watch for. Normally 3.3uH isn't a lot, but these coils are using a heavy gauge wire for current purposes. A non-linear "form"(core) may induce spikes or an instability resulting in diode death.

Who is Steve. I thought drlava's name was Andrew.:thinking:
At least that is what it says on the Google checkout.
"Thanks for your recent purchase from Andrew Kibler"
Or did you get them from somewhere else?

Steven @ Laser Surplus Parts.com
That was the link that was given me for them somewhere on here.
It was linked off the .edu site or with it when I was looking for them.

Ok that makes sense. I was a little confused.
You know you hear some things about him but I got a batch of V5 from LSP when the flexdrives were out of stock last time and I got them quick and in new condition. No complaints here.:beer:

If you knew the back story you wouldn't do any business with him. Dont ask me though.

I don't think it's been pointed out yet, but thermal paste does not harden and set.
If you're gluing the driver to the heatsink, you want thermal adhesive.
Thermal paste/compound does not harden and set. It's designed to stay as a goop for as long as possible.
I have made this mistake before, except the other way around. An Athlon XP die will happily separate from the rest of the CPU
Thermal adhesive can be made by cutting normal thermal paste with two-part epoxy. Anywhere from 30/70 up to 50/50 paste/epoxy works fine. Any more, and it turns into a elastic goop. Change the amount of epoxy to paste if you need the material to be harder, or more elastic.

Is that not drlavas site? People were saying drlava had them in stock, I couldn't find them in anywhere but there. Every place I looked showed out of stock.
Ah, that arrived today! Arctic Thermal Adheasive. 7gm. :san:
Good tip though! Nice to know.

Removed one reference to it as paste in the OP but don't see the quote you are quoting.
I am actually surprised I called it that. It is a lot of writing on some of these but I do normally call it thermal adhesive.:beer:

I got lazy, and used the quote brackets from another post.
Here's the OP where the inconsistency is.
EDIT: Will remove excessively long post after DTR replies.
