What is a PCBA and How to Create Your Custom PCBA?
Introduction of PCBA

A Printed Circuit Board Assembly (PCBA) is a piece of electrical equipment that supports and connects the electrical and electronic components. It uses conductive tracks, pads, and features that are etched from copper layers, laminated on or between the sheet layers of a substrate that is non-conductive. The components are usually soldered on the PCB to connect them electrically and mechanically.

How to Get a Custom PCBA

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 also needs to be connected to external devices such as potentiometers and LEDs etc.

Step 2. Once everything is placed in its place, an electric rule check is run to ensure no evident faults. ;

These may include breaks in wires or connections or any missing connection to ground or power etc. Once the schematic is done, the board layout view is checked.

Step 3. The components are moved at proper places that make good sense.

Step 4. For the board production, signals are assigned to each layer and varying signals on a single layer cannot touch.

Step 5. After the signals are laid, a design rule check needs to run to ensure proper placement of holes, traces, etc. These rules can be customized as well.

Step 6. If the design is approved, the design files can be uploaded.
