Bare Printed Circuit Board Electrical Test

Bare Printed Circuit Board Electrical Test

Following the manufacturing process of a printed circuit board, we can perform a visual inspection to find any potential problems.  While that may work fine for a two-layer PCB, for multi-layer PCBs, it is almost impossible to visually inspect the internal layers once the board has been completed.  Therefore, visual tests are done on inner layers prior to lamination to find any problems and correct them.  However, the only way… Read More

Photocopier Teardown from EEVblog

Photocopier Teardown from EEVblog

Well here we have Dave Jones again with one of his Teardown Tuesdays. He does a great job of breakdown a wide variety of electronic devices in his weekly show. This time out I wanted to show you this teardown of a Photocopier. The technology in these machines has really changed over the last ten years. They used to be very analog based machines and now they are all digital.… Read More

Electronics Thermal Heatsink Design Tutorial

Electronics Thermal Heatsink Design Tutorial

Here is another great video from Dave Jones of EEVBlog. A follow on from some of the recent blogs that have involved basic thermal heatsink calculation. This time around Dave takes you though the basic theory of thermal design and how heatsink calculations work. Then there are some real world temperature measurements to see how close to the theory we get. How do you read a heatsink thermal response graph?… Read More

Makerbot Thing-O-Matic 3D Printer Time Lapse Build

Makerbot Thing-O-Matic 3D Printer Time Lapse Build

I wonder if you have ever seen one of these 3D printers.  They are used to make quick prototype designs and even can be used to make final production products. They are quite an amazing piece of technology.  There are several ways that the process works but basically it is taking a polymer and applying it a small layer at a time until the final object is completed. There are… Read More
