Cob (chip on board) is already a mature technology in e-commerce, but the average team lead is not familiar with its programming, maybe it is because it uses some wire bond's physical electrical circuit (IC) Sealing technology, as a result, many finished products or foundry engineers of industrial electronic circuit boards are eager to find related technical personnel. In the past, most cob products were only used in some low-cost consumer products.
power supply is closed to avoid electric shock.
In the picture, the left side is the high-power cement resistance, which can withstand high-power excess. The right side is the common resistance, and the color code on it indicates its resistance value and error.

In the previous article, we talked about SDA. The steps of DDA can be understood as follows: Execute SDA first, and then perform the steps unique to DDA. this article focuses on this unique step. this unique step not only enables DDA to have the SDA function (to ensure that the data on the card is not modified after personalization), but also to prevent the card from being copied and forged.

(1) Power failure: This is a very simple fault, the general LCD display extension inside the power supply and external power supply two, outside the common some. Regardless of that power supply, its structure is much simpler than the CRT monitor's power supply, and is usually vulnerable to a number of small components, such as the safety pipe, Rectifier bridge. 300V filter capacitor, power switch, power management IC
U disk's composition structure is relatively simple, mainly by USB plug, crystal oscillator, the main control chip, voltage regulator IC (LDO), PCB board, SMD resistor, capacitance, Flash (flash), light-emitting diodes (LED) and other components.

Cool, Enterprise Library released!
OverviewThe patterns Practices Enterprise Library is a library of application blocks designed to assist developers with common enterprise development challenges. application blocks are a type of guidance, provided as source code that can be used "as is," extended, or modified by developers to use on enterprise development projects. enterprise Library features new and updated versions of application blocks that were previusly available as stand-alo
