In the initial days of electronics manufacturing, engineers and designers have realized that sometimes designing a temporary circuit needs without soldering the components. So, an engineer took cardboard and arranged several rows into it to place nails. As per the circuit diagram, they placed components and nailed them through short wire pieces. The electrical connection can be provided by wrapping wire or soldering around the nails, and then components could be soldered to the wires. But by … [Read more...]
