2 Installation Precautions(1) Do Not Use The Capacitor That Has Been Energized On The Device. Except For Capacitors That Are Removed For Periodic Inspection During Electrical Inspection, They Cannot Be Used Again.(2) Even If The Capacitor Is Discharged, A Voltage (Re-Flash Voltage) May Be Generated Between The Terminals. In This Case, Discharge Through A 1kΩ Resistor.(3) The Leakage Current Of Capacitors Stored For More Than Half A Year May Increase. In This Case, Perform Voltage Processing With A 1kΩ Resistor.(4) After Confirming The Rated Value (Electrostatic Capacity And Voltage) Of The Capacitor, Install It.(5) After Confirming The Polarity Of The Capacitor, Install It.(6) Do Not Drop The Capacitor To The Ground. Do Not Use A Capacitor That Has Fallen Behind.(7) Do Not Deform The Capac...

Soldering is a process in which two pieces of metals are joined together, with the help of a filler metal referred to as a solder. This filler metal has a low melting point compared to that of the metals to be soldered. The solder is melted in the soldering process. There are different ways in which soldering can be done. You must be thinking what are the different types of soldering used? Read the following post to get an answer to this question.What are the Different Types of Soldering?There are different types of soldering done based on the application. Here are a few types of soldering tha...

The low cost and generally competitive quality of printed circuit boards (PCBs) produced in China has tempted ever more electronics manufacturers worldwide to offshore their PCB sourcing to that country over the past decade.South Africa has been far from immune from this phenomenon, and nor will the country be exempt from an impending copper shortage, warns local supplier Cirtech EDA’s business development director, Nechan Naicker.Gaining a global perspectiveCirtech EDA’s existence dates back to early 2015, when local PCB manufacturer Cirtech joined forces with the PCB sourcing arm of EDA Tech...

In recent years, the PCB industry has become a global industry, the world has more than 2800 printed circuit board production enterprises, the scale has more than 50 billion U.S. dollars, accounting for more than the total output value of the electronic component industry is 1/4, the whole industry in the largest proportion, and a rising trend, is the main pillar of the future development of electronic component industry. But by 2008 the outbreak of the international financial crisis and the debt crisis in 2012 and other markets, the global PCB industry through a difficult period, with the ris...

Are you thinking of using a rigid/flex format for a PCB? If so, the first and most obvious answer to the question ‘why?’ is to make use of the flexibility and to permit movement between two conventional boards – even if the movement is limited to providing vibration tolerance.Flex circuits that actually flex in regular use can, however, be considered a special case; very often, the intent is to provide an efficient interconnect between two boards that do not lie in the same plane. In such cases, the flexible part may only flex during final assembly of the product and never do so again.Flex-rig...

It may seem something of an understatement, but Phil Mayo, director of sales for Altium UK, believes: “The PCB is important.” And perhaps that’s one reason why the workshop and conference sessions addressing PCB design at last year’s Electronics Design Show (EDS) attracted record numbers of engineers.In his workshop presentation, Mayo noted: “For decades, the humble PCB has been the cornerstone of all electronic products. Today, perceptions of the PCB range from a simple interconnect medium to a fundamental component of a complex electronic system. Regardless of the perception, the reality is ...

Capacitors are like batteries in that they store and release energy. However, capacitors use separated electrical charges, rather than chemical reactions, to store energy. The charged particles enable energy to be stored and released very quickly. Imagine an electric vehicle that can accelerate from zero to 60 miles per hour at the same rate as a gasoline-powered sports car. There are no batteries that can power that type of acceleration because they release their energy too slowly. Capacitors, however, could be up to the job -- if they contained the right materials.  NC State physicist D...

Oct. 21, 2015, was the day that Doc Brown and Marty McFly landed in the future in their DeLorean, with time travel made possible by a "flux capacitor."  While the flux capacitor still conjures sci-fi images, capacitors are now key components of portable electronics, computing systems and electric vehicles.  In contrast to batteries, which offer high storage capacity but slow delivery of energy, capacitors provide fast delivery but poor storage capacity.  A great deal of effort has been devoted to improving this feature -- known asenergy density -- of dielectric ca...
