How do I design a rigid-flex PCB?

2019-07-02

Frankly speaking, the design of rigid-flex board is much more complicated than other traditional PCB design so that there are plenty of aspects that we should pay attention to, such as rigid-flex transitional areas, related routing, vias design, etc.

Does a resistor reduce current and voltage?

2019-07-01

Absolutely! In fact, resistor is like a current limiter, which limits the amount of current flowing through a device.

Where can I have someone check my schematic and PCB?

2019-07-01

In the process of PCB design, a correct schematic is an essential precondition for PCB fabrication so that the schematic must be guaranteed before generating rhe netlist into the PCB.

Can other materials replace gold in electronics?

2019-06-28

Yup. In fact, there are a kind of new copper-based material (based on copper nanoparticles) that can be used to replace those expensive precious metals of printed electronics, such as silver, gold, etc.

If you are soldering something, how long does it take for the solder to cool?

2019-06-28

Well, it actually depends upon the components that we are soldering; In general, it usually takes 10 seconds for those SMD resistors and capacitors to cool. However, for ICs, which mainly replies on the its volume. For example, it takes about 20 seconds f

Why does open-circuit test give core loss/short-circuit test give copper loss?

2019-06-26

Iron core losses: The magnetic flux in the transformer is flowing on the iron core, and the iron core has magnetoresistance to the magnetic flux, which will generate heat so that this is why open-circuit test gives iron core losses; Copper losses: Coil

Why are vias needed in electronic circuits?

2019-06-26

Honestly, it mainly refers to the function of vias. As you probably know, vias are mainly used to connect lines of each layer. That’s to say, after metallizing treatment, the circuit boards on both sides of vias are connected together.
