Hi All,

I have been using liquid solder (paste) with great success. 5 years ago, I started out with a sample sent to me for free by a vendor. It was sent without an applicator, so using it on really small smt was impossible, couldn't apply small amounts of solder without the special (and pricey) micro-applicator.

The stuff was great, I used it with a conventional Weller soldering station and with the pyropen hot air 'iron'. It was supposed to have a 3 month shelf life, but I stored it in the refrigerator and it has lasted 5 years although it has degraded to the point where I wouldn't trust it on smt.

So, I need to buy more liquid solder and want a more modest quantity, and something that comes with an inexpensive applicator so it will dispense small amounts needed for smt pads.

Any suggestion as to which product to buy and where to buy it??? Please, no Radio Shack recommends, been there, done that...I've got questions, they have blank stares:>: Reputable vendors only please.

Thanks,

Art

Wow, Art, you scared me for a moment. I once saw a
brand new Heathkit HW-101 that a young new ham had
assembled using the plastic type "liquid solder". It
never did work.

I've had limited success using solder paste in a
plastic oral syringe given to me by a friendly
pharmacist. It's hardly small enough for any type of
precision, but at least it's controllable and useable
for small jobs or repairs. You nearly have to
despense some onto a toothpick to apply. Pretty messy
that way, but with a little patience I got by.

Thanks Dave.

It is pretty toxic stuff too, and dispensing with a toothpick is going to mean wiping the toothpick onto something once in awhile to keep the toothpick clean and prevent a big glob of it from forming on the tip.

I was hoping for something a bit more elegant in terms of the dispenser, but not elegant to the point of costing 200 dollars just for the micro dispensing hardware.

My original sample came in a syringe and was perfect for doing DIP packages and through hole type components. A smaller syringe might be better....but can't imagine it being fine enough for smt dispensing.

Thanks,

Art
