The design quality calculation for a single electrical circuit can be expanded to include several design targets for the circuit....

Many electronic products require thermal cooling systems to remove heat generated in the electronic boxes and to maintain proper operating temperatures in the transistor junctions within the PCBs....

In mechanical design, statistical design analysis can be substituted for worst-case tolerance analysis. A case study in mechanical design tolerance analysis is that of a typical vibrating probe that i...

A product is made of many parts that have been made from different materials. Many electronic products use parts made from plastics, sheet metal, machined parts, rubber, castings, etc....

There is increasing use of computer aided design (CAD) systems for i mechanical design. They make it convenient to present drawings in 3D to the designer, and hence offer a better view of parts mating...

Statistical analysis involves the application of statistical probability distributions to analyzing tolerances for assemblies. It will prevent overly conservative designs, which can increase the cost...

It is important to note that the parts used in a product are divided into standard or off-the-shelf parts and nonstandard or designed parts. Examples of standard parts are bearings, shafts, pulleys, b...

The product design process starts with the concept models, proceeds to prototype models, and then on to production. The concept and prototype models are primarily made in the companies, model shop or ...
