Moore’s law is the observation that the number of transistors in a dense integrated circuit doubles approximately every two years. As the cost of computer power to the consumer falls, the cost for producers to fulfill Moore's law follows an opposite trend: R&D, manufacturing and test costs have increased steadily with each new generation of chips. Rising manufacturing costs are an important consideration for the sustaining of Moore's law.

Once summer is over, the year slips away: I can’t believe we are in the last month of the 2016.

3D printing will have a big impact on everyone in years to come – whether they realize it or not.

One standard to rule them all.

A new survey reveals the tradeoffs designers experience in their preferred CAD tools.

As often as not, not understanding assembly leads to problems in design.

“Mistake” and “error” possess similar meanings in dictionaries. Yet there is a subtle difference between them. A mistake means selecting an incorrect path, when during the time of selection, the correct path is unknown. In contrary, an “error” signifies the selection of an incorrect solution or an incorrect path, when during the time of selection all the data required for a correct decision are supposed to be known. For example: a spelling mistake or a gross error.

Herewith are several common mistakes in PCB design. The consequences of these errors, usually detected during fabrication and assembly, may negatively affect board quality and reliability, and increase production cost and time to market.
