How do I calculate the copper thickness of PCB?

2019-05-14

Generally, the copper thickness is calculated scientifically according to the current of PCB circuit; In addition, there is no denying that the thicker the copper, the better the PCB is; However, the cost will be higher correspondingly. Therefore, it is e

Are the electronics at risk of damage through static electricity?

2019-05-13

Yes! As we all know, static electricity tends to attract the dust, which will reduce the insulation resistance of components. In other words, static electricity can shorten the service life of components to some degree;

What is a dry or cold solder joint? How it can be eliminated?

2019-05-13

Cold solder joint means that there are a small quantity of tin column in the welding spot, which causes bad contactin the circuit.

Is baking a graphics card in my oven dangerous?

2019-05-10

Nope. You know, if a graphics card is damaged, the fault may be caused by cold solder joint of SMD components such as graphics card memory or core. In this case, with the help of high temperature treatment like baking in the oven, it will melt the solder

How can we identify the BGA area of PCB?

2019-05-10

BGA means Ball Grid Array, which is a special type of SMD chip package; So why is it called BGA? In fact, under the bottom of the package, all pins look like spherality and array as a grid pattern.

How can I store my electronic components?

2019-05-09

Well, electronic components must be stored in the clean, ventilated and non-corrosive gas warehouse; Meanwhile, unless otherwise specified, the temperature and relative humidity of the warehouse must also meet the following requirements:

Do stains on the solder points of a PCB mean that components are damaged?

2019-05-09

Not really. There are two possible reasons, such as the PCB isn't cleaned wellbefore welding or components are damaged.

Is an electric circuit patentable?

2019-05-08

Yes! an electric circuit is patentable. As long as your electric circuit complies with these three characteristics of patent such as novelty, creativity and practicability. After all, Patent Law only states that we can’t apply for the content of patent su

Why can an inductive sensor detect only metal?

2019-05-08

In fact, it is determined by the structure and working principle of the inductive sensor itself. In other words, only when the metal object enters into the inductive field will there be the output state in the inductive output terminal.

What are the applications and benefits of analog and digital electronics?

2019-05-07

As you probably know, analog and digital circuit are the foundation of the electronics industry. What’s more, analog circuit mainly refers to amplifier, oscillating circuit, feedback, various operational circuits and so on; While the digital circuit inclu
