I'm looking for Do-it Yourselft articles on soldering surface mount
components. I can't afford the IR equipment that commercial board
houses use. I'm particularly interested in soldering the new ROHS
components that require lead free solder. The lead free solders
require higher temperatures. Also, do board coatings prevent problems
with tin whiskers that grow from the lead free solders?
I do surface mount assembly with an ordinary Metcal soldering station.
I solder Rs and Cs using a small tip cartridge, and fine-pitch devices
by drag-soldering with a mini-hoof cartridge.
Metcal, ordinary? Those are the Mercedes-Benzes of solder stations. They
are great but the ones I have used at clients were well north of $500.

I got one of the older STSS power units cheap on Ebay. It can
be used with the current MX-500 handpieces and cartridges.

The whole system cost me about 120 GBP, less than a new Weller system.


It's weird, I looked and indeed, Farnell charges you guys an arm and a leg. It was the same when I bought a new scope. Came from Farnell-UK (with a UK power cord!) yet cost me a whole lot less via Newark. Same for irons:

$127 for a WES51 station is a darn good deal. Maybe it's the RoHS compliance why they have you guys over the barrel.
