surface mount soldering..
 

can anyone recommend at diy way of flow soldering surface mount components??
i ask as making somr boards up that are totally sm, and well i am going
blind trying to solder them using iron!!

thanks g0zen..

If you're careful and have the luxury of a little practice to build
technique, you can use a heat gun (hot air) to reflow solder SMT parts, but
it takes solder paste rather than wire solder (which requires some care in
handling and storage), and it does take practice to get the feel for your
particular heat gun and develop the technique to get the best results.

Another technique is the "toaster oven method" ... search the Yahoo groups
for "ez-bake" for a message thread with a wealth of information.

interesting????!!

will investigate more..

question..how do you put 100 sm parts on board and get it to oven???does the
water based solder act as glue till it melts??

That looks like a good way to go, it would sure beat trying to solder
individual leads, but... it looks like the minimum order quantity is 10 tubes
of solder, for $120 or so. (And these are the small 35g tubes. Digikey's are
more like $800 for the minimum qty of 500g tubes.)

Anyone know a source for small quantity (1-3 tubes) purchases?

What I have done in the past is to tin the pads where the parts are going
to be mounted and then I use two soldering irons. One on each pad and it
pulls the part right down into a good position.

Ok ok I hear the question now. What about parts with more than two leads?

That is a valid and good question. Only tin two pads for that part and use
the soldering iron on each one of the pads to get the part mounted and in
position to finish soldering the rest of the leads one at a time.
