Aoyue 2702 |

This is really the Aoyue 2702 model.
I have it, and my only complaint is the desoldering tool doesn't seem to work well. My plastic desoldering pump seems to have more suction power.
But the soldering iron and hot air is good.
What would be really nice is if the desoldering tool and soldering iron can be plugged in at the same time. Instead, you have to use one or the other, unscrew, plug in, screw back... it's easier and quicker for me to grab my plastic desoldering tool.
The hot air is also handy for shrinking shrink-tubing.

Yes, I agree there on your point. I thought that was a bit strange. Probably because of power supply limitations etc ... The good thing is that the iron and desolder gun come up to temperature within a few seconds so it really was not too big a deal for me. I set the iron for about 390 C and it gives me the friendly "I am ready Beep" within a few seconds.  The 30 minute auto shut down feature is very nice also .....

And so it is .... Well, the same price also so I did not get ripped off. I guess it's like buying TV sets, you never really know who the OEM is ....
One comment though is that if you have a multilayer board with a ground planes that suck up all the heat, the plastic desolderer mayl not work so well but this situation does not arise very often. I usually preheat the area with a hot air gun first then try to use the plastic tool. For simple two layer boards, a wick works good in a pinch also but sometimes you get that nasty bit of solder that just won't "suck" out ... geez !! 
Thanks for you comments OH, I am impressed with your products, website and promo video of the Mic preamplifier and power supply products BTW !!!!!

What I do is after pull out the component is add a bit of fresh solder to the pad, then use the plastic pump on the OPPOSITE side of the board. Heat the pad, then suck the solder from the other side. IT WORKS and sucks the hole cleanly... even if you have plated-through hole or big ground planes.
For really, really stubborn holes, I use tiny drill bits to drill through the solder and open up the hole.
It doesn't take much force, you can just use your fingers and thumb to turn the bit around.

Thanks! If you need to build some mic pre kits or power supplies, try some of mine.

The price is fairly good to at $249.00 USD. It comes with many attachments as you will see and will allow you to start doing surface mount work on top of all the through hole stuff.
