Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

    Is there a suggested temp for this solder?

    • Member #910010 / about 7 years ago / 1

      I second this request. From my understanding lead-free solder often has a higher melting temperature than leaded, and different soldering irons (or settings on one) can certainly have different temperatures. It would be good to have the melting point along with any recommended temperature clearly noted somewhere.

    I'm not sure about the lead-free part. I just did a lead test on a tube I just ordered. I really hope my order was incorrectly picked, because the lead-test I did came out positive (containing lead). I really hope I accidentally received TOL-09162 (the leaded version).

    Doesn't "60/40" generally refer to the tin/lead content of the solder? In that case, there's nothing 60/40 about lead-free solder.

    I have several tubes of solder purchased from Sparkfun. How can identify what type of solder it is?

    "This is you basic" should be "This is your basic"

  • I tested against the lead free I had at home and I was not impressed. Why? Because this one took much longer time to melt.

It's solder.

Heat it. It melts. Things connect. Magic happens.

Good !

Nice to solder , easy to pull packaging...

I really wanted to make a review for this product !

The thing is, it's nearly impossible to differentiate the lead free and the leaded when you have both in your pocket, maybe you could ad a vinyl sticker on it ?

It's solder?

I mean, I'm not really sure how to review this. It's solder. It melts. It makes things connect to each other.

But I guess the real reason why I'm liking this is because of the high silver amount. When you're working on audio equipment and need to solder things, this mixture is one of the better conductors when it comes to solder, barring any exotic solder materials. So, 5/5 stars from me. Definitely need to keep more on hand. But it would be nice if it were labelled so I didn't have to guess which tube of solder is which.

Melts Smoothly

I used it with my hakko soldering station and it melts. No issues. I like it.
