You need a well-designed PCB for the effective functioning of the device, and you can have it by focusing on the DFM or Design for Manufacturing. Different requirements are there in terms of PCB design, management, and fabrication that you have to follow. At the same time, you should consider the timeline to have a circuit board within your budget. PCB and DFM Issues Having well-executed CAD tools is easy, but these tools cause certain DFM issues which need lots of effort to solve. Sometimes a PCB is correct in terms of electrical requirements, but it is hard to manufacture because you ...
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 ...
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 ...
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 ...
Electronic goods are increasing with a time that demands smart, high density, and multifunctional PCBs. You will see smarter PCBs than in the past as their geometric index is continuously increasing. Advanced PCBs with reduced sizes need to have updated soldering with a better electrical connection. Large holes result in poor connections, affecting a product, hence, the hole size has reduced to half. PCB’s need different holes for connections and one of them is plated half hole and designers also call it a castellated hole. It is a drilled hole finished in copper and it exists on the board boundaries. As holes ...
