The quality of the soldering has a tremendous impact on the overall quality of the PCB. Through soldering, different parts of the PCB are connected to other electrical components to make a PCB ...

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 ...

I've got a Bosch dishwasher that, like many Bosch dishwashers loves to melt the solder off the heater relay and requires repair every 12-18 months. (Bosch dishwasher engineers are completely ...

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 ...

Through-hole assembly means bending leads on components and putting the leads through holes in the circuit board, then soldering them in place, and trimming the wires. That took up too much space and ...

I'm going to be celebrating the 38th anniversary of my 21st birthday next month (coincidentally, it will also be the 29th anniversary of my 30th birthday). The reason I mention this is that my eyes ...

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 ...
