Dan, one of my Facebook pals, contacted me asking about selecting a soldering iron:
” Quick inquiry … I’m looking for a brand-new soldering iron. would certainly you advise anything under 40 bucks without a soldering station? I’m burning out of my RadioShack 45 watt iron with the screw on tips (and also having to make use of a bench mill everyday to clean the pointers).”.
I’ve been asked this inquiry quite a bit, so I assumed it was time to put something together clarifying about blowpipes, change and also tinning.
The first point I would recommend is obtaining an adjustable temperature welding torch, and get made use of to setting the appropriate temperature level for the different sorts of parts you are working with – hotter for bigger gauge, and colder for thinner, finer work. I normally work in the 325F to 400F range. I have actually been utilizing the Velleman LAB1U, it has a constructed in multi-meter and also power supply. These can be a bit costly, so have a look at the Weller brand – often they take place sale for around $40. I would certainly prevent the Cold Heat soldering irons – they are unsuitable for delicate electronics, as are the big soldering “weapon” type irons.
I used to use fairly big gauge solder and also suggestions, however simply recently (after doing a lot of surface-mount work) switched over to 1/32 ? pointer and 0.32 ? diameter solder. This allows for much finer control with less overspill.
My blowpipe has actually an integrated in “moist sponge” to wipe excess solder in between uses. In the past I have made use of routine paper towels to do the exact same work, but a specialized sponge with a round opening cut in the middle really functions finest.
The following point I would not lack is are some “Assisting Hands” – these are sets of crocodile clips that can be used to hold the work surface while you focus on the soldering. this is really crucial, as it will not be lengthy prior to you know that you require 4 hands to solder things.
Also better than helping hands is a:.
I purchased one of these 2 years ago and also it’s confirmed to be invaluable. The brand name I use is “PanaVise” and also they include a series of alternatives as well as bases – Fry’s brings them, as well as they are offered online. You can put the entire PCB you are working on into the vice, insert the components and afterwards simply turn it over to solder.
If you find that you are having difficulty obtaining an excellent solder joint then it’s most likely since the warm transfer isn’t functioning properly, or the elements are filthy. Applying some solder change to the joint location will really aid – I’ve been using a change pen for years and would not want to be without one.
Pointer Tinner and also Cleaner.
When you first fit a brand-new soldering iron suggestion it will certainly be brilliant, shiny and also very difficult to function with. Some individuals will certainly use great sandpaper to break in a new pointer but I favor to dip the new pointer into some RadioShack “Suggestion Tinner and Cleanser”. It’s additionally a good concept to dip the soldering iron after you are finished, and before you switch off.
You need to get something mounted on your bench to divert the fumes away from your face if you do a whole lot of soldering. It’s not suggested to breath in solder fumes in any way. I use a little follower, yet a correct extractor is a very good suggestion.
These are used to trim off excess part cable (the “leg”) after soldering. The flat base is important to get the cut as close to the PCB as feasible.
That just about covers the basics of soldering, I would certainly also consider obtaining a loupe (magnifier), some solder wick as well as solder “fool” for elimination, wire pole dancers and also isopropyl alcohol and an old toothbrush for change elimination.

The first thing I would recommend is obtaining an adjustable temperature level soldering iron, and also get made use of to setting the proper temperature for the different types of components you are functioning with – hotter for larger gauge, and cooler for thinner, finer work. I would stay clear of the Cold Warmth soldering irons – they are inappropriate for fragile electronic devices, as are the big soldering “weapon” type irons.
When you soldering iron tips first fit a new soldering iron suggestion it will be bright, glossy and also really tough to function with. It’s additionally a good suggestion to dip the soldering iron after you are completed, and before you change off.
