What is impedance control?

2019-07-03

As long as the trace on the PCB matches the file transfer rate, the signal is able to avoid interference. However, when the rate reaches 100Mhz or more, impedance control must be performed.

How are plated holes in PCBs made?

2019-07-02

1. Dipping the PCB into the sink or flushing it directly in order to allow the wall of hole to get sufficient wetting. After wetting, pay attention to that there are no bubbles in the wall of the hole; 2. Placing the PCB in the plating bath and letting

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

How can cold solder joints be prevented?

2019-06-27

As we all know, cold solder joint is one of the common line faults of PCBA, so why does it happen?

Which sites provide PCB packaging?

2019-06-27

1. Official website of the components brand: The components specification data including packaging information will be provided on it; 2. Third-party platforms: Specifications and packaging information of components will also be provided on such platfo

Which factors in PCB design that affect PCB Assembly?

2019-06-27

PCB Assembly is conducted according to the production data of PCB design. Excellent PCB design is extremely helpful for subsequent PCB Assembly, while imperfect design will affect the assembly process and even the quality of products. So Which factors in
