Manual Wiring on Prototyping Circuit Board, Electronic Design

Prototyping boards allows electronic components to be manually soldered and secure neatly onto a board platform. Compare to plugging the electronics component onto a temporary breadboard, a prototyping board offers a better reliability. It is robust enough for a one-time project deployment. There are many types of prototyping board to suit your prototyping needs.

Benefits of manually wired prototype circuit

  • Design changes flexibility during the development phase of the first prototype.
  • Less initial investment for proof of concept.
  • PCB Design drawing need not be drawn first.

Disadvantages

  • A Slow and Expensive method if your production quantity is large. (eg. > 10pcs)
  • Not suitable for fine pitch IC chips and components.
  • Limited choice of connectors.

 

Some samples of designed electronic prototype circuit manually wired on a prototyping circuit board.

Neat custom component layout with the point to point soldering using wire wrap wires on an FR4 prototyping board. The FR4 board prototype boards have rows/columns of holes which are inter-connection on both sides of the board. The top of the PCB is neatly mounted with through hole components, while the back of the PCB has the electronic connection with the point to point soldering.

Standard Resistor Value

When designing your electronic circuit, we often have to come across to make a design decision on the resistor value to choose. If the design permits, it will be better to choose a value that is commonly available. This is to ensure that you can easily purchase the resistor’s value at a competitive pricing.

The following is a reference table of the SMD resistor’s value. The number below indicates the popularity of the resistor’s value. Popularity lower than 40 is not shown on this chart.

Half Bridge MOSFET Driver

Half Bridge Driver for N-ch MOSFET is different from Half Bridge Driver for P-ch/N-ch MOSFET. There are advantages of using two N-ch MOSFET instead of using N-ch/P-ch MOSFET.
