MCL's standard base thickness is 0.062 inches, or 1/16 inch, with a 10% tolerance. This is a very common PCB thickness and is typically considered the industry standard. The reason for this is that 1/16 inch was the size of Bakelite sheets manufactured in the early days of PCB fabrication. While this thickness is the most common, however ...

Step 8: Lamination. PCB stack-up lamination. In this step, the stacks are pressed and heated in a vacuum chamber. The Lamination process begins by applying vacuum to remove all the entrapped air and gases. Later, heat and pressure are applied to the stack so the resin in the prepreg undergoes a molecular bonding.

It is extremely vital to study the importance of copper traces in PCB. This is because these traces are the connecting tracks between the two electronic components on a PCB. In high current application PCBs have high width copper traces.Hence it is very important for PCB layout design engineer to know what trace width should be selected for a particular power circuit or device.

For low power signal traces it is generally advised to keep traces small to increase the available space available for routing. However, minimum trace width recommendations from manufacturers should be kept in mind. The minimum trace widths and spacing are manufacturer and process dependent and usually vary between 3mils and 8mils.

Image 2: PCB Guard Rings. While a guard ring is one of the most critical parts of an AC circuit, it is only as effective as the impedance in the course. A guard ring is always connected to a low-impedance voltage source to nullify the otherwise current leakage produced by high impedance nodes on the circuit.

In PCB design, effective thermal conductivity is an important aspect used in thermal modelling and analysis because it allows engineers to predict how well a populated PCB would conduct heat based on specific assumptions and models. With electronic modules continuing to shrink in size, it is a parameter that deserves attention amongst designers.

SMT PCB. SMT is the process of placing electronic components (like transistors, diodes, capacitors etc) on PCBs. The most common method of SMT assembly is placing the component on the PCB using a pick and place machine which picks up a component from its storage container and places it on the PCB. This is done one at a time.
