Generally, there is no need an accurate capacitance (Only need a capacitance range) in most circuits; However, there is one exception,oscillatory circuit always requires an quite precise value to capacitor.
Apparently, there are at least more than one reason why a PCB doesn’t work.
For instance, schematic is not correct enough, PCB layout doesn’t follow the designer’s requirements to handle signals, PCB exists quality problem, certain components are false
Honestly, an Arduino can’t power any motors directly on account of the output current of its main control chip is less than 100mA, which can only drive a LED; (PS: If we power the motor with an Arduino forcedly, the board will be broken finally.)
I guess, you wanna try to express why there is no right angle trace on PCB. Well, it’s just because that the corner(not right angle) trace can be as capacitive load like a transmission line, which is pretty helpful to retard rise time;
Frankly speaking, it mainly considers from the features of analog computer and digital computer.
Analog computer: The computer inputs analog signal whose numerical value is represented by continuous quantity and the operation process is continuous; How
Not really. It is quite not easy to do well in PCB layout, especially for those special products.
As you probably know, PCB layout is like the bridge to undertake the schematic of design engineer and realize the product performance with the help of EDA
When it comes to the advantages of using the soldering station, there are four points we should know:
a. Antistatic ( To prevent precision chip from breakdown by electrostatic during welding.)
b. Dormancy( To save energy and prolong the service life
No problem. There is one thing that you need concern that is cleaning the excessive flux.
Here are three ways for your reference:
1.Volatilizing the excessive flux as much as possible by increasing the preheating temperature;
2.Distributing it evenly
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
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;
