PCB Design & Layout
What is PCB Design?
PCB design is the process by which electronic components are arranged on a circuit board in order to create a functional product. It involves identifying the components that will be used in the circuit, creating a schematic diagram that shows the shape of the board and the placement of each component, tweaking the component placement to make sure that the components are connected in the right way, and then constructing a physical prototype of the PCB.
What is PCB Layout?
PCB layout is the process of arranging the components on the PCB. It is a very important step in the manufacturing process. The PCB designer has to ensure that there are no shorts between the components and other components in the PCB. There must be a clearance of at least 0.5 mm between the components. The components are placed on the PCB according to the following rules.

SMT Process
What is the SMT Process?
SMT is a highly automated operation, there are several steps involved in the process:
- Solder Paste Printing
- SMT Pick and Place
- Reflow Soldering
PCB Surface Treatment
PCB Silkscreen
This process is very important because the bare copper in your PCB will quickly oxidize and oxidized copper is a no go for electronics. Silkscreen is a printed image that adheres to the surface of the PCB and transfers ink to the surface where it is then peeled off. This can be done manually or with a press. The most basic one is a card printer that can do up to two colors at a time. The most important part of this process is to make sure that the PCB must be cleaned and degreased before the ink is put on.
PCB Test
AOI Test
The AOI test is an important method used to evaluate the quality of the printed circuit boards. It checks the connectivity of the components and the silkscreening of the board. The AOI test is performed by placing a known good component on the board and observing how it connects to the other components. If there are any solder balls that are not bridged, the board does not pass the AOI test. Most commonly, the AOI test is used to ensure that there are no unbridged balls of solder on the printed circuit boards.
Functional Test
PCB functional testing is the most comprehensive testing regimen for determining whether a manufactured board can leave the factory and be shipped to the customer. The goal is to identify manufacturing defects that affect reliability, missing or incorrect components, and opens/shorts in nets or solder connections.
