China's prices going up
Due to the turmoil of the world's financial markets, the cost of China's manufacturing services has virtually gone unnoticed.

It was a belief that the price different for production from the east to the west would go on for many years, but due to the changes in the worlds economies in the past few months it is apparent that China could become a more expensive place to make electronic goods in the future.

This price increase has already started with the raising costs in fuel. The cost of transporting products from China to Europe or the US has doubled in the recent years.
Inflation in China is now running at higher than 5% which is putting presser on wages and the Chinese government has been putting in laws for Chinese workers regarding minimum wage.

As the cost of production continues to rise, much production was already left China. There are signs that due to the recent economic changes some firms have revisited the benefits of having a European production base.

PCB Layout and EMI
At Quantum CAD we believe that to have a PCB layout that controls any electromagnetic interference (EMI) and noise is the most important aspects of a good reliable design.

A noisy system can lead to unstable logic and phase-locked loop failures that reduce overall reliability, as well there is potential that the device will not pass government standards for EMI.

The main sources of noise in embedded systems come from switching power supplies, common mode current, and high frequency switching signals, oscillators, phase-locked loop circuits, crosstalk between signals and the transmission line effect.Quantum CAD - The most respected PCB Design brand in the UK!

At Quantum CAD we offer a complete, unique electronic and PCB design experience. At the forefront of the PCB design community we are committed to offering a comprehensive range of design services for almost any type of electronic product, from initial concept through to manufacturing.

PCB Rapid CAD CAM Benefits

PCB design is rarely simple or easy, particularly when each new project demands shorter project times, reduced unit costs or greater design complexity. Therefore Quantum CAD's experience and expertise can prove invaluable in meeting these challenges. Over the years we have successfully completed hundreds of PCB design projects for some of the world’s most demanding and largest electronics manufacturers in the following sectors:

Telecommunications
Consumer electronics
Automotive
Aerospace
Industrial electronics
Oil and Gas

The optimum place to start is looking at the noise generated in the power supply lines. This noise comes from current spikes caused by switching logic or instantaneous current requests from devices down the line. The problem gets worse as the frequency of the switching increases. Decoupling capacitors between power and ground do help in terms of smoothing out the voltage spikes but this will not significantly eliminate EMI. In some cases the addition of an inductor behind the decoupling capacitor can help eliminate some of the current instability. The inductor has high resistance at high frequencies impeding some of the noise. To avoid excessive impedance a resistor in parallel can limit the inductors effects. The inductor should be placed as close as possible to the area of the circuit that is generating the noise. Next all the traces should be kept as short as possible cutting down on the effective area of the loops that act as
