I have corrected, enhanced. moderated my design notes from my earlier Amps-n-Volts News Letter. This was sent thru Your Mailing List Provider for a few years. Even now some errors and misconceptions of mine, might still exist in these posts. Any feedback or correction is welcome. My knowledge is limited to my experience, observation, perception, learning [...] How To Learn Electronics Theory must be studied once and referred again and again as you do practicals. One is by building DIY projects and then modifying them. Also Repair of equipment, troubleshooting, testing and calibrating. Then you know how components behave and real life limitations. Now design and engineer a product and test [...] Selecting the parts for your product design, choosing the components intelligently is a part of Product Design Engineering. Budget, Availability, Size, Alternate Vendors, Product Life and Quantity to be manufactured are some factors that determine the selection of a prudent and experienced design professional. To choose the right type of part, an exhuastive knowledge of the behaviour [...] Prototype Fabrication Sometimes a component can be defective, may not be what it is labeled or may be of a wrong value. In manufacturing 100% incoming inspection of components can catch these errors, Before Assembly of prototypes just test all passive and active components with a DMM and put all ICs in bases, then troubleshooting is [...] PCB Thermal Design Care for Analog Circuit Stability If you have a hot power chip near a DC analog circuit, the values will drift, take time to stabilize, this happens even if you use 1% MFR 100ppm. The impact is more if the heatsink is not used and vents and coolers are absent, So in [...] Production, especially prototype testing and Pilot Production exposes lot of engineering and serviceability issues. When you mass produce, it is more streamlined, yet the scope for improvement never ends. The process should always be open to feedback and improvements. The tracks or components on a PCB should not be near the mounting holes, the tracks may [...] |
