I spent 40 years in the electronics industry; 35 of those years as a soldering instructor. I taught soldering classes mainly in the US at our manufacturing plant, but also in Europe, Japan, and Singapore.

I hung out my own shingle as a soldering consultant for a while, that worked OK for a few years. I had some articles published in technical journals for the printed circuit board industry, and I was invited to speak at conferences in Minneapolis, San Jose, and Singapore. But that all dried up.

Along the way I held various positions in a few different companies, from entry-level electronics assembler to Quality Manager. I've attended all of their solder training programs. Without fail, they all focused on the specifications, i.e., what the finished solder joint needs to look like, how much solder, etc., but they didn't teach the "how" part of the soldering equation. The specifications are only one leg of the soldering tripod. You only need three things to make perfect solder joints every time:

1. Clean parts
2. The right amount of heat for the right amount of time
3. The specifications

While the corporate soldering certifications are being done by the big training companies, I figure a layman's hand-soldering handbook is feasible. I'm getting too old to pitch my classes and travel around the country. I have plenty of knowledge and research to produce a book, and I can do that right here at my desk.

My goal was always to enable people with the knowledge, the tools, and the confidence to produce 100% reliable solder joints by hand, every time. There is no magic to this. It is strictly about chemistry and thermal management. The electronics industry produces some unbelievably high quality products these days due to computer aided design and manufacturing automation, but...unlike machines, people can recognize when a change needs to be made to the process in order to be confident of the quality. That is the primary focus of my book.

By the way, my initial soldering certification came from the Naval Air Technical Training Command, Naval Air Station Whidbey Island WA, 1973. "Miniature and Micro-miniature Component Repair." 4 weeks.

After about a year of Avionics schools, I finally landed in the Intermediate Maintenance shop in my squadron, VA-145. This meant I did not work up on the flight deck of the carrier, but in the computer lab; we ran diagnostics on the black boxes and repaired the circuit boards, etc.

My first job was an air data computer that had a defective encoder, with probably 24 wires, maybe 28 ga (small.) I got a soldering iron and replaced the part, and it resembled a fouled up open face fishing reel on steroids, multi-color even. My shop Chief took one look at that and said "Didn't they send you to soldering school?" I had to tell him "No." He called the training guys and had some choice nautical words for them

The following Monday I was in MILSTD Soldering school, LOL.

Cool, that is some interesting history, dread.
Good to know there's a top-notch soldering guy on hand, good
luck with the book, keep us posted on progress!

Canada .... brrr
I had no idea that soldering could be a profession and thought that nowadays all would be done by robots in production. My dad in his leisure time would often be seen with a soldering iron taking apart old TVs and radios and I still have his sizable collection oft vacuum tubes. He always used a brown paste to help the solder flow. It stank like hell. I firmly believe that inhaling this stuff caused the bladder cancer that killed him.

Oh and he taught me. If the cat chews a cord I have it joined back together in no time.

Most modern electronics are surface mount and thus wave-soldered. Hand soldering is an art form and one that I fear will be lost soon.

As a fun aside I learned about wave soldering when fixing my Playstation 3 duing a "reflow" process that floored me because it worked.

Looking forward to it. I am basically self taught but some of the Heathkit gear I put together decades ago is still running so my bad was good enough. Especially interested in how technique differs with type of solder. Looking forward to ordering a signed first edition :)

That was simply Colophony or Rosin (obtained mainly from Pine trees), the same stuff you use for violin bow hair to make it vibrate. Rosin was used as a soldering flux for a long time. I still use it also in liquid form simply mixed in spiritus.

Actually, most surface mount electronics are reflowed in convection or infrared ovens, not wave-soldered. Wave soldering is mainly used on through-hole circuit boards. And, not to be too argumentative, but hand soldering is not an art form, it is an exact science, the whole premise of my book.

It is an art form for me. That's why I'll get the book :)

I stand corrected.

Sorry to be a pita GAD, but I'm real passionate about this subject. So many soldering certification programs do treat it as an art form, and it's not. Like my old mentor, Ralph Woodgate put it: "they're trying to make solder joint sculptors out of people." Appearance of the finished solder joint is really quite secondary to other far more important quality parameters.

Hand-soldering is more rare today, but it will always be with us - point-to-point wiring, repairs, component replacements, etc. Another important concept I learned in the Navy: "Non-destructive repair." There should be no evidence of a repair when you're done, including things like burning adjacent wires with your soldering iron or puddles of flux left behind.

My father owned a small electro-mechanical manufacturing business, and while I was growing up he brought down to the factory during the summers to learn the business. I started on the assembly line, soldering components to military radio chassis. The best solders were women, at least on that line. They had the patience for it.

I worked at Western Electric for many years. The first three years, I had a soldering iron in my hand all day, everyday, for 8 hours.

In a pinch, lemon juice works as a flux because it reacts with the oxides that form on metals.

Since we're all telling our soldering stories I'll chip in mine. My Father was sent to Radio Repair School in WWII and electronics became a hobby for the rest of his life. (He was a research Chemist as a profession.) He was always building electronic equipment including inventing the "Christmas Tree" used in Drag Racing. (That's a story for another day!)

He taught me how to solder wires at and early age, maybe 10 or 11. When I was around 13 I got into 1/24th scale Slot Car Racing. My Father had "silver soldered" a few "tubular" cars back in he 60's but now the cars were fabricated from flat brass plate and rod with anglewinder motor orientation. Here are a few interweb photos for reference. (These are not mine!)

The "Store-Bought" cars were pretty pricey so I decided I could design and build my own! This is where I really learned to solder! If you didn't have everything attached well it would just come apart on the track! (I ran at a commercial place on a track with a huge banked corner that imposed a lot of force on the car! Here is a similar type track.)

Amazingly, I was pretty successful with my hand-built cars against the "Store-Bought" cars.

I know this is a lot different then the type of soldering being discussed, but it was soldering non-the-less. It took a lot of patience (and heat), to get the brass plates hot enough to solder a good joint!

I’m loving this thread!

I did some cheap-ass stained glass soldering using lead in high school — I was terrible at it.
