    This is not a Vintage, but many people who buy no brand soldering Irons from AliExpress, they actually buy a fake product. Good to know.

    Too Cheap!!! $1 DIY 1000°C Soldering Iron By Spark Plug
    https://www.youtube.com/watch?v=AdDu0lmFdoA

    Hi guys ! Today I’m going to make a $1 soldering iron out of a Pen Case and truck’s spark plugs!

    That is not a spark plug it is a glow plug but then you would not get any comments LOL – Also use – - 24 Volt.- Glow plugs are around 150 Watt. So 150 / 12 = 12.5 Amp – Most trucks are 24 Volt So 150 / 24 = 6.25 Amps.

    Dangerous Prototypes flux-off solder flux test
    https://www.youtube.com/watch?v=uJNjNOAxvqY

    We test four types of flux we had around the workshop: syringe, liquid, marker, and paste. Which is easiest?

    Solder’s Days Should Be Numbered—There Is a Better Way
    Opinion

    It seems that just about every year, the PCB assemblers encounter a new solder challenge as it moves to smaller, much more capable products with increased performance requirements. Ever smaller components, finer pitches, smaller pads, finer traces, and spaces on the PCB continue to challenge those companies tasked with building complex products with high yields and solid reliability. Although doable to a degree, we’re reaching the limit of what can be done efficiently and economically. An objective observer would quickly conclude that the industry cannot, and should not, continue down this path.

    When we look at some of the most common causes of failure in an electronic product, solder is at the core.

    Although solder defects are well known and fairly well managed, solder’s constraints on the industry have not been well understood.

    With all of solder’s constraints and limitations—which limit industry progress—it is time to ask: What would a world without solder be like?

    At Occam, we have developed a process that supplants solder—and PCBs—with a new methodology for component assembly. We sometimes describe it as reverse order processing.

    Our vision is to first attach components to a “component board” and test that assembly before encapsulation and circuitization. This ensures that all assemblies are known to be good at the outset. There are several methods for adding component connections, including traditional plating techniques and additive printed circuits (printed electronics).

    By removing solder, thermal excursions are greatly diminished.

    The contention point would be the presence of lead. Solder with lead is significantly easier to use, especially on a hobbyist basis, but used on an industrial scale on devices that end up in the waste stream, it becomes an environmental poison of some concern. Use of lead-containing solder in commercially manufactured devices is somewhere between “discouraged” and “illegal.”

    NC presumably means No-Clean (not acid/aqueous) flux.

    Fine for general purpose electronic work, as long as you’re not doing IPC production rework on a lead-free build.
