Soldering to a PC board can be tricky: Too much heat can make the copper trace lift right off the board substrate. Use a soldering pencil rated at 15-25 watts, no more. (Watch the video; story ...

Improves wetting: Flux helps molten solder flow smoothly (or “wet”) across the surfaces, promoting even coverage and a strong ...

This is a circuit which helps us in turning off the soldering iron automatically when it detects overheating and thereby avoids it from getting damaged. This is a circuit which helps us in turning off ...

Here is a simple but inexpensive inverter for using a small soldering iron (25W, 35W, etc) In the absence of mains supply. It uses eight transistors and a few resistors and capacitors. Transistors Q1 ...

When writing my last article, I came upon something I thought had been lost to the seven seas of YouTube: the old-school “Basic Soldering Lesson” series from Pace Worldwide. This nine-episode-long ...

The basic metallurgy of solder. How to make a solder joint. How to repair a circuit board. The vintageTEK museum is a geek’s paradise to tour if visiting the Portland, Oregon area. The museum has ...

Assemble functional circuits quickly with the soldering irons at Sears think[box]. The heated tip on each iron melts solder to form electrical connections. For projects of this nature, you bring the ...

May & Scofield manufacturers electronic controls and systems, and needed to fulfill a contract for automotive flex circuits which forbade hand soldering. It turned to capital equipment distributor ...

Any robot that moves needs actuators—motors that move parts of the robot around. While robot actuators have been around since the dawn of machines, they have some issues. For one, it is very difficult ...

If you fancy building simple electronic circuits but don’t own a soldering iron or would rather not go down that route. You might be interested in a new method of creating electronic circuits using a ...
