Go back in the thread? Theres 17 pages! lol. I guess I will.

A couple questions though.

Is the output voltage high enough for bluray diodes?

Can these be modified to power red diodes?

Use a boost for anything blue... use a linear or buck? for red or IR..

Or fry me with your laser!

I searched for reflow solder paste Kester and got lots of Videos Google is your friend...

Yes 180$ / 500g

your reading correctly...

Do you realize that 500g of solder paste would be enough to build your own Cray XT5?

I am yet to use up half of my 15g tube.

I don't know about cheaper per gram... but that's sort of irrelevant if there's no way humanly possible to use 500g on your own.

Go for a 15g tube, for $15. Until you actually reflow stuff, you may no realize how absolutely little of the stuff you actually need.

yeah, i've got a massive amount that i'll never use....2lbs of it i think.

the tubes looked smaller in the picture, like 10cc tubes, but they ended up being like 100cc

I thought of getting some 5cc syringes and 22g IV catheters and making it available to people who wanted it. with a single 5cc syringe you could probably reflow over 1000 boards.

Thank you Tom! I don't mind paying/wasting a few dimes per build to go with the grade 1 automotive IC.

Especially the +125°C spec.

Especially the +125°C spec.
cool man, automotive grade is a good choice

just imagine if they were making these for aerospace applications

*Facepalm*

The spec is the same. The +125C spec is the same for all of the LM3410s we've been using. The only difference that "Q" gets you, is supposedly improved defect detection AT the spec (of +125C) at the factory.

Lol, this isn't some magical version of the IC that can handle more heat....
