Is it practical to create a PCB antenna for NFC?

2019-03-21

Yes! It’s definitely practical. NFC: Near Field Communication, by now, which is a vital part of mobile payment system. In other words, NFC antenna has became one of indispensable component in the fabrication of mobile PCBA.

Why does a current always choose to go to the resistance which is lower?

2019-03-21

As a matter of fact, the current tends to flow from high voltage to low voltage; The only difference is that the current turns higher when the resistance is lower. I guess, this is the phenomenon you observe in the circuit.

How do I find the SMD/SMT equivalent for through-hole components?

2019-03-21

No worry, it’s not a big deal! Actually, if you find the same specification(equivalent), you can totally try to replace DIP resistor/ transistor/ capacitor with SMT/SMD ones.

How high frequencies are used or can be used in ferrite core transformers?

2019-03-20

Generally speaking, 50–200HZ is used in ferrite core transformer;

Can a cold solder connection cause fire on the PCB?

2019-03-20

Not really. Cold solder: Little solder around the solder point that is only easy to cause bad contact instead. Possible reason: Poor solder paste or processing technology;

Why is copper used in PCB instead of aluminum?

2019-03-20

It depends. According to the metal base material, both copper and aluminum are used in PCB but with various application; However, if we discuss this question from PCB Plating perspective, then we’ll get another totally different answer:

Where are most semiconductors manufactured?

2019-03-19

At present, USA is the most semiconductors manufacturer around the world; While in China, Taiwan should be the No.1 in terms of manufacturing semiconductors.

What is the direction of the current flow when a switch is closed?

2019-03-19

If I understand what you mean correctly: “What is the direction of the current in the outside of the power supply when a switch is closed?” Normally, in the outside of the power supply, the current flows from the positive electrode to the negative el

What causes the filament of a light bulb to glow so bright?

2019-03-19

The light bulb makes good use of the heat effect of current, that’s to say, as long as the light filament heats up to an incandescent state, which will glow so bright.
