Need to hand solder 100+ MC-E's

[mds82]

I have 100+ Cree MC-E's that i need to fit into a very tight spot and will need to hand solder them because i can not fit a board into the area.

currently i'm gueing them down, tinning the 4 tips, soldering a bar across them ( so they can all be in parallel).

I'm looking for any suggestions to make this easier ... can i dip each end into a solder pot? use solder paste to make it easier?

i know the LED is 7x9mm, i have an area up to 1/2 inch x 1/2 inch to work with, and not much height to work with either.

I always find with that sort of job I waste more time looking for a clever way to do it than it would have taken if I just got on with it!

If i could find someone to make a Very small and think MCPCB, that would be great actually - are there any placed to order these from?

did you talk to led-tech.de or leds.de? both do pretty much "custom" setups. What about some of the board houses?

Perhaps I misread, but won't your method of putting a "bar across them" actually put the dies in parallel as opposed to series?

Yup - i goofed on that. i ment parallel. I wasnt paying attention when i wrote that i guess

I'm interested in the mega heatsink being used here!

Hah! Nerd!

I've got some pretty nifty sinks. Some solid coppers, some stacked fin coppers, some composite (.5cm copper plate, stacked metal fins) and some extruded aluminum. Wish I had some with heatpipes, but those are all in use.

Someday I'll put them to use heheh

what exactly are you trying to light with 100 MCE's?

It wouldn't happen to be a $3000 aquarium light would it?:duh2:

 

[alpg88]

just 100 leds?????
that is no big deal, shouldn't take more than 30 min.

 

[jasonck08]

Wow! What on earth are you trying to make!?

100 MCE's as in 70,000 lumens worth!

Keep us updated!

I agree here. The only time I try to find a better way to do something is if I'll be making 10 or 100 or 1000 of them. With one-off projects it makes more sense to just hack away until it's done.

100 LEDs + 8 pins each = 800 pins to solder
Before soldering you'll have to prime with some flux, depending on location legs may have to be modified, etc.

At minimum preparation and solder that's 1600 steps not to mention re-dos.
an intense 30 min workout, if thats even possible. :shrug:

100 MCE??:sick2:

can we expect beamshot? :twothumbs

 

[znomit]

Regretting not getting P7s yet?

 

[DimeRazorback]

What sort of project is this going to be!!

 

[Th232]

Are these for 100+ individual lights, or one absolutely massive light?

If so, I think we've got a contender for the BIG Lights thread.

 

[Marduke]

If you have access to one, a stereo microscope makes such small soldering jobs MUCH easier.

oh, 800, didn't think it was that many,

for priming pins i use a tube from a q tip, i just dip it into the flux, than put it onto the pin, once you get a hang of it, it is pretty fast process
