Hi, for the past almost 10 years I've been soldering with a soldering station that had a knob to regulate the temperature, your average cheap $30 one. With practice and experience I learned the "sweet spot" of the knob to work comfy and nicely, which was about 300-350ºC according to the sticker, which might be lower or way lower at the tip.
Recently I purchased an awesome station that uses tips that tell you the temperature of the tip, so now I know "exactly" the temperature I'm working with. My solder alloy is:
Which according to Wikipedia it melts at 183ºC (solidus) or 190ºC (liquidus). Now that's new, I always thought the melting point is the temperature at which the substance or alloy starts to change state from solid to liquid, of course at standard pressure. So having 2 melting points, I don't know what that means.
May be it's the range?
Like at 182ºC or below we are "99.99%" certain it's solid and above 190ºC is liquid? And between those we have a mix of liquid/solid?
Anyways, the question is... should I look at the specific melting point of the solder I'm working with and put the soldering station at that temperature? Or may be a little higher to make the process quick?
I see most solder alloys melt between 180ºC and 250ºC, so if you are working with these alloys, when is the 350ºC temperature recommended? When desoldering? It's better to have the tip at 350ºC because that means you reach way faster the melting point and put less stress in the components?
Thank you!
