What is frying pan reflow?

The equivalent of making a boat out of paper and then trying to set sail across the Atlantic.

Ok i was curious so I googled it. It seems you want to stick the smd parts on with solder paste and cook the circuit board?

Remember when i dropped a comment a while back saying that you would go crazy soldering these together? Yeah....

That's how you do it commercially, dunno if that's the easiest way without the tools though. Generally you use a metal screen with holes cut out of it for the pads of the board, you place the board under it and squeegee the paste over the screen making the paste the thickness of the metal screen, on the pads.

Then in a commercial environment a computer controlled robot picks up the parts and places them onto the pads with the paste on them.

Then the boards are run through an oven melting the paste into solder.

But you have to be fairly careful with the oven part, it has to be very level (or your parts slide somewhere else) and you can't let it be at the melting point for too long or you risk messing up some of the parts or also getting the sliding problem, and too short and you don't fully melt the solder paste. The oven is usually part of a conveyor belt too, so the boards aren't just sitting there they're moving through temperature ranges, I'm not sure how well it would work in a normal oven.

Too Excited!!!

They are 3mm surface mount so fraid thats not likely
and i'll get pix asap.

Any update on the pics. :

^^^^ ;D

bump for pixxx

pics pleasezzz

How's the soldering coming?

Eagerly awaiting pics!

Also, If I opted to solder mine myself would I get them any faster?

I think for one of them I might not be using the board, I might try just soldering the components to eachother... and I suppose it'd be easier to not to have to unsolder them...

By the way...

What's R3 (ie the big 2cm long thing that looks like a battery on the right side of the board)?

An awfully big resistor?

thats the pot

If I understand correctly the parts are surface mount parts, which would mean they don't have any legs (and are also very small) so that would be some accomplishment to solder them together without using a board.

see this post[/url]... the pot apparently a 3mm surface mount dealie.. the pic shows a 20mm long component... maybe a 10W resistor?

z000z: I've done it before... using magnification and a fine tipped iron it shouldn't really be that hard...
redesigning it three-dimensionally to fit in the smallest space possible is the hard part.
I know it's a crazy idea, but I'd like to try it... I'd like to see if I can fit this driver into a roughly 1cm cube if possible.

 

[z000z]

That would be pretty cool to see, make sure and post pics if you do.

 

[pwnstar]

hey i know it must be a pain get all of these soldered..
but any updates?

 

[pseudolobster]

I hate to be annoying, but is there any update on this?

it's been well over 2 weeks since you've had the boards, could you post some pics or at least let us know how it's going ?
