Significance of Copper Coating in PCB Design

Printed circuit boards have a certain unused area, which is coated with copper known as copper coating or filling. There are several benefits of copper coating and one of them is to minimize the impedance of ground wire, as well as enhance the anti-interference and power supply, and minimize the voltage droppings. The copper coating also helps prevent the deformation of a PCB during soldering. However, you have to manage copper coating properly to avoid certain issues that we will discuss here and find ways to resolve. PCB has wirings distributed capacitance regarding high frequencies. The designer knows that when the length ...

High-Frequency PC Board Applications, Specifications, and Challenges

Some electronic products need special signals for which you have to make a high-frequency PC Board. Such a circuit board can provide 500 MHz to 2 GHz frequency that is ideal for microwaves, a radio frequency, and certain mobile applications that involve high-speed designs. Several electronic components and switches are complex and need to transfer signals at a fast speed which is provided by high-frequency PCBs. Such boards need special materials because ordinary materials can affect signal transmission due to a poor Er value. Designers have to consider certain factors while designing the high-frequency Printed Circuit Board [1] that we will ...

Why printed circuit board manufacturers use plated slots ?

Printed Circuit Board Plated Slots Slots are holes, which are either plated or non- plated-through. So, plated slots are holes plated in copper. And we use them for electrical connections on the PCB. A through slot is the one that goes to the entire depth of the board, starting from one end to another. Whereas a PCB outline or edge also has plating called side plating. printed circuit board manufacturers use plated slots for components packaging, however, non-plated slots are also in practice. But, PCB with multiple layers have only plated-through slots. Why Prefer Plated Slots? PCB assembly [1]involves different designs and components, ...

What is High TG In PC Board Fabrication?

The making of PCB involves different steps, technologies, and terms, and TG is one such term that refers to the Glass Transition Temperature. High TG PCB is the board made at a high temperature. We will discuss this topic in detail, including the TG value, features, applications, materials, parameters, and much more. What is High TG PCB? If a PCB’s temperature goes beyond a set TG value, its condition will change. Like, the solid board will turn rubbery, affecting a PCB’s function. Depending on where you use a PCB, the temperature of the application should be at least 10 to 20C less ...

What is Back Drilling in PC Board Manufacturing?

Back Drilling is a way to remove the copper barrel’s stub from the through-hole. A stub is an unused part of the plated-through holes as it does not perform any function on the circuit, so it’s not needed. For example, while producing a 12-layer PCB you have to make a hole to connect the first to 10th layers. In general, via holes are drilled and then copper plating happens which connects the first layer to the 12 layers, whereas you only have to connect the first layer to the tenth layer. The part from the 11 to 12 layer is useless as ...
