The Terminologies and Concepts of Circuit Boards

The Terminologies and Concepts of Circuit Boards, printed circuit boards are PCBs, a plate or board used to place different components to make an electrical or electronic device. There are interconnections between various parts of the circuit boards in the form of routes of copper. The simplest of the circuit board is having the traces of coppers, which are different interconnecting components of the device. The circuit boards come in layers such as layer 1, layer 2, layer 3, etc.

1. The Solder Mask

For the generation of the electrical components, the process of assembly is needed. For this process, dedicated machinery is required. The assembly process is achieved by soldering the details over the circuit board. For the prevention of the circuit boards being short-circuited accidentally, the solder mask is being used by the manufacturers of the printed circuit boards, separating two nets apart. The standard color of the solder mask used is green. Moreover, blue or red is also used.

2. The Terminologies and Concepts of Circuit BoardsOverlay

The overlaying is when the manufacturing company is printing the information of the design onto the solder mask. This process is done to simplify the process of assembly and the repair and verification process. The overlay is printed onto the test points and the orientation position and referencing the components placed on the circuit.

The pads are the trim surfaces of the copper on the circuit boards, allowing the soldering of the components onto the board. The places are the pieces of copper where the tops of the members are lied to be sold.

4. The Copper Tracks

The copper tracks are the paths of copper for the conduction of the electrical components being sold to the circuit board.
