The PCB development life cycle is long and complex. However, one of the major phases in this development life cycle is known as thePCB designphase. During this phase, you will have to develop a blueprint that has all the information required to create your printed circuit board. That means...
After resistors, capacitors are perhaps the most common components of a circuit board. Capacitors are among the top choices of PCB enthusiasts as well. However, we use capacitors less in comparison to resistors. The basic function of a capacitor is to store charge in it. A capacitor includes ...
The outer container should be clearly labeled as fragile and contain shipping/handling instructions. Apply all necessary shipping labels. This layered approach minimizes motion and isolates PCBs from vibration, shock, and abrasion during shipping. Adjust packaging for PCB size, quantity and shipment mode...
The top layer of PCB typically has conductive materials such as copper, which helps direct electric signals from one part to another. A PCB, however, is not an entire construction in itself as it does not contain electronic components. In contrast, a Printed Circuit Board Assembly (PCBA) is...
Double-sided- This type of circuit board has components mounted on both surfaces. Each surface is defined as a signal layer in the PCB stack-up, so the surfaces will contain traces that carry signals between components. Multi-layer PCBs- These boards have conductors on internal layers that car...
This format does not identify a single document but constitutes the standard for the production of printed circuit boards. The different files, exported at the end of a project, contain descriptions of the electrical connections, the tracks, the vias and the pads. These are vector documents made...
Most boards already contain JTAG headers for programming or debug so there are no extra design requirements. Where do I get information about the JTAG in my devices? In order to run any boundary scan based testing it is necessary to have some information about the implementation of JTAG on th...

PCB Layers 25-26: NamesTop/NamesBottom As the name suggests, these two layers contain the top and bottom print for your component names. Every component on your PCB has a unique name, also called a reference designator, and will look something like R1, C1, D1, etc. ...
The complex numbers contain information about the amplitude and phase of the frequency components in the original time signal as shown in Figure 4. The amplitude of the complex number is the hypotenuse. The phase is the angle θ. Figure 4: The Complex Plane Equations 2 and 3 show the relati...
