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...

An aluminum electrolytic capacitor, usually simply called an electrolytic capacitor (e-cap), is a capacitor whose anode (+) consists of pure aluminum foil with an etched surface, covered with a uniformly very thin barrier layer of insulating aluminum oxide, which operates as a dielectric. The electrolyte, which covers the rough surface of the oxide layer, operates as the second electrode, the cathode (-).  E-caps have the largest capacitance values per unit volume compared to the two other main conventional capacitor families, ceramic and plastic film capacitors, but articulately sma...

The printed circuit board (PCB) market, on the basis of design, is segmented into low end, mainstream and high end. Printed circuit boards (PCB) are a common method of assembling modern electronic circuits which comprises one or more insulating layers and one or more copper layers containing the signal traces, power and grounds as well. The design of a PCB needs more incessant efforts than the design of an electrical circuit.The modern systems consist of multilayer boards with eight layers. Earlier, components were mounted on the top layer in holes which extended through all layers, hence...

Among manufacturers, there is a common perception that the more complicated the concept, the longer it takes to produce a market-ready functional object. This is especially relevant for the highly competitive electronics industry, where product complexity is continuously increasing and improved time-to-market is a primary business objective. It all starts with the Printed Circuit Board (PCB) and electronics design and development companies’ need for shorter, more agile and efficient product development cycles.Most of today’s PCB prototypes are produced by traditional subtractive manufacturing ...

Overcoming the Potential for FailuresComponent manufacturers are constantly developing smaller and innovative packages for components that are just fractions of a millimeter and have board to component clearances of less than a mil. New accessories that allow placement of these nearly invisible parts can be found in pick and place machines. When the components are placed very close together, how does one effectively clean under something that is extremely small?No lead solder is a relatively recent legislated fact of life that necessitated new fluxes, new solder, new solder processing equipmen...

World printed circuit board (PCB) production reached an estimated $58.2 billion in 2016, up 2.2% in real terms, while North American PCB production decreased a mere 0.1%, according to IPC’s newly published World PCB Production Report for the Year 2016. The North American PCB market also continued its downward trend, but at a slowing rate of just -1.7% in 2016, based on data published this week in IPC’s 2017 Annual Report on the North American PCB Industry.The World PCB Production Report shows that more than half the world’s PCBs based on value are now produced in China, but Taiwanese companies...

Space savings, greater reliability, low mass, and high ductility are some of the advantages offered by flexible PCBs, but designers must also prepare for their complexity.Space savings, greater reliability, low mass, and high ductility are some of the advantages offered by flexible PCBs, but designers must also prepare for their complexity.Flexible printed circuit boards (PCBs) aren’t much different than rigid boards during the design phase, except that the designer must account for the mechanical complexity associated with flex circuits (Fig. 1). For instance, a flexible PCB can tear if ...
