Improving Speed by PCB Routing Techniques in PCB Layout
[1] There has been immense development in physical design aspects of designing with the advent of CAD Tools. It’s not that long ago, that we were hand taping on multiple layers of mylar at 2:1, 4:1 and even 8:1, and then having to shoot the artwork with a camera to reduce the film to 1:1. The power of today’s CAD tools can maximize your time whether it be circuit design, circuit simulation, PCB design, or system-level simulation. In turn, Complex designs can be optimized quicker and more efficiently. We know that copper traces are used as interconnects or bridges between two ...
Acceptability Criteria of Printed Circuit Boards, what standard do you use?
[1] As a printed circuit board manufacturer, PNC Inc [2]., Nutley, NJ, our criteria of acceptability during the inspection process is determined by IPC–A–600. The scope of this document describes the acceptable and non-conforming conditions of a bare boards either externally or internally during the final inspection process. The inspection criteria is then broken down into three classifications of acceptability, Class I, Class II and Class III. Each class’s acceptance criteria is then again broken down into three areas, target condition, acceptable, and nonconforming for the imperfections in question. At times there can be a disconnect or confusion between the end-user ...
Grounding in Printed Circuit Board Design
[1] As we advance into the future, we want everything to be faster, cheaper, compact and durable. Everything around us is electrical. Moore’s law predicted that numbers of transistors per square inch of PCB will double every 2 years and it’s been true too date. Well theoretically it sounds good. But implementing new products with the above requirement comes with a cost. In order to reduce the unit cost of the design, due to noise. Various techniques have been developed in the past few decades to reduce noise in the circuits as the number of components increases and the available ...
Power Electronics: The Hidden Technology
In the last decade of 21st century, power electronics has seen a tremendous amount of growth due to smaller and accurate designs working at the heart of each and every electronic device, machine, appliance or system. The current arena of power electronics is dominated by providing the low noise accurate supply voltage rails and huge power handling capacity at higher efficiency in small factor. Power electronics in layman terms is defined as the high power circuit design converting one level into different level of electrical energy. Power systems in current decade vary from range of mW (cellular mobile phones) to hundreds ...
