Printed Circuit Board Assembly is a term that refers to circuit boards assembled with electronic components like capacitors, resistors, and IC (Integrated Circuit). A PCBA can be a semi-product of anything, from an LED light to an electronic truck. The integration of PCBAs is the system of a complex electrical product. When PCBAs are installed with enclosures, they become box builds or end products.
Step1. The first step in designing a custom PCB is in creating a schematic view.
The required component is placed on a canvas and their pins are connected with lines that represent the electrical connections. The components usually are taken from a component library which is a part of the design software.
There may be multiple variations of the same components depending upon the type of package being used e.g. dual inline package or a surface-mounted chip. The packages may seem the same in the schematic view but are very different in the layout view where the board is actually designed.
Apart from the components and their electrical connections, power, and ground signals are also needed. Also, connectors have to be placed on the PCB to make a place for power and ground. The board is also required to be connected to external devices such as potentiometers and LEDs etc
