What does a “footprint” mean in PCB design?

2019-06-03

A footprint is called a "land pattern", which is mainly used during PCB layout so that an electronic component gets soldered onto the PCB conveniently. Furthermore, footprint still consists of several layers information, including the copper lan

Are IC package dimensions standard?

2019-06-03

Yep! All IC package dimensions are standard, such as DFN, QFN, QFP, BGA, SOP and so on, which comply with the Standards of JEDEC ( Joint Electron Device Engineering Council, USA.)

What are layers related to PCB?

2019-05-30

It seems that you are talking about trace layers of PCB. In fact, it includes both surface layer and inner layer, which are conductive by vias or pins of DIP components.

What is a zero printed circuit board?

2019-05-30

In PCB manufacturing, there are three stages which belong to print: Printed trace, printed solder mask and printed silkscreen. However, the only huge difference that is their various printed content;

Is LED light harmful to eyes?

2019-05-29

Yes but not huge. You know, LED light is luminous via light-emitting diode when the current is switched on;

What is the scope of electronics manufacturing?

What is the role of an Inductor in an electrical circuit?

2019-05-28

When it comes to the role(function) of an inductor, limiting AC current, forming high/low pass filter, phase-shifting circuit and resonant circuit with resistor or capacitor are the major considerations.

Why where old pcbs brownish/beige and now they are green?

2019-05-28

Old brownish/beige PCBs: It smells like metal and its PCB parameters are too large to some degree as well as low process technology relatively; Apart from that, yellow solder mask is not expensive; New Green PCBs: Green solder mask is more likely to ha

How do you find faulty soldering?

2019-05-27

When it comes to the faulty soldering, cold solder joint leads to open circuit, tin connected cuases short circuit, incorrect welding direction / place of components are the major considerations, which can be virtually discovered by virtual inspection and

What came first, potential difference (voltage) or current?

2019-05-27

In our daily life, you may often hear the saying like this “where there is voltage there must be current following.” However, the truth is that is not absolutebecause current changes in different circuit.
