It is made of non-conductive material like fiberglass, with copper tracks to connect components.
PCBs can be single-sided, double-sided, or multi-layered depending on the complexity of th...
- Q2. What is the active and passive components?
- Ans.
Active components require a power source to operate, while passive components do not.
Active components require an external power source to function, such as transistors and integrated circuits.
Passive components do not require an external power source, such as resistors and capacitors.
Active components can control the flow of electricity, while passive components simply store or dissipate energy.
Examples of active comp...
- Q3. What is the difference between resistance and capacitor?
- Ans.
Resistance is the opposition to the flow of current in a circuit, while a capacitor stores and releases electrical energy.
Resistance limits the flow of current, while a capacitor stores and releases charge.
Resistance is measured in ohms, while capacitance is measured in farads.
Examples of resistors include carbon film resistors, while examples of capacitors include ceramic capacitors.
Resistance dissipates energy in the...
- Q4. What do you know about SMT ?
- Ans.
SMT stands for Surface Mount Technology, a method of electronic component assembly where components are mounted directly onto the surface of a printed circuit board (PCB).
SMT components are smaller and lighter than through-hole components, allowing for higher component density on PCBs.
SMT components are typically mounted using solder paste and reflow soldering techniques.
SMT technology allows for automated assembly pro...
