What Is the Difference Between AC and DC?
Electric current refers to the movement of electrons along the conductor like a wire. Electrical energy flows in two ways, alternating current (AC) and direct current (DC). The difference between AC and DC has to do with the direction the electrons are flowing.
What Is Photophobia (Light Sensitivity)?
Photophobia refers to increased sensitivity to light. People with this condition think that normal light is too bright. Photophobia may present as eye discomfort, pain, or an avoidance reaction.
What Percentage of Electricity Is Used for Lighting in a Typical House?
When the electricity bill is high, the biggest culprit is the lights that remain on. It is thought that a significant amount of energy will be saved when the lights are turned off or dimmed. Is it possible to cut the electric bill in half by simply turning off the lights? Short answer; No.
Is Infrared Light Harmful?
Infrared light is basically heat radiation. It has the lowest energy per photon and is the safest type of light. However, when it becomes dense enough, it can damage living tissue. As with most things, the right amount is beneficial, too much is harmful.
What Is the Difference Between Reflow Soldering and Wave Soldering?
Soldering is an important step in the electronic circuit manufacturing process. Manufacturers use soldering to securely connect electronic components to the circuit board. In the electronics industry, there are two main forms of soldering as reflow soldering and wave soldering.
What Is Surface Mount Technology (SMT)?
Surface Mount Technology (SMT) is a general term for mounting electronic components directly on the PCB surface. Components such as resistors, capacitors, transistors, integrated circuits can be soldered to the surface of the circuit board thanks to this technology.
What Is a Flexible PCB?
Flexible PCB is a circuit board that can be bent as desired according to the surface or area to be mounted. Flexible PCBs can be bent easily without damaging the circuit. Flexible PCBs are found in many devices that we use in our daily life, such as smartphones, tablets, cameras, laptops, printers.
What Is a Cold Solder Joint?
Cold solder joint is a problem that occurs when the solder is not completely melted during soldering. The cold solder joint increases the electrical resistance of the solder joint. This can lead to some problems by reducing the reliability of the solder joint.
What Is the Standard PCB Thickness?
Printed circuit board (PCB) forms the basis of most electronic devices. PCBs are quite simple in structure and usually consist of only one or two layers. PCBs are used in…
