Sometimes you have to try something and have it not go well before you even know what questions to ask. This is one of those times.
I recently soldered header pins to a 2x16 LCD display. This was my first attempt at soldering. It "worked" but it seemed harder than it should be, and I don't have a ton of confidence that the connections won't mysteriously become intermittent. I'm sure part of the problem is my technique, but I'm also wondering if I need different materials.
I have a Weller WES51 soldering station (comes with PES51 point tip iron), brand new, so that should be fine.
From reading something here, I thought I would purchase some Kester solder. It's fair to say I had no idea how many types of solder exist. Kester has like 6 families of solder wire and 10 families of flux! (Who knew?)
So I bought some "245 flux cored wire" SN63PB37 0.025in. I assumed (not sure I'm correct on this) that since this was "flux cored" I did not need to buy flux.
Sorry for the long explanation, but here are my questions:
I know there are some soldering videos around, perhaps on youtube, but can someone recommend one that they feel is well done? I would have no idea how to judge the quality of the soldering info.
Did I buy the right product? To be honest, I don't really understand all the different types. I know I want leaded, I've seen people here recommend 60/40 or 63/37. I like the idea of a "no clean" solder, which I believe this one is. And the 0.025 size seems ok. I guess my question is mostly about the different types of cores.
Do I need flux? One of my problems is that I wanted the hot solder to surround the header pin. The best I could do was to kind of build a hill from the contact area to the pin. Would putting some flux around the pin help? And if I do want flux, which of the 10 types do I want?
