The purpose of packageICs, unlike resistors and capacitors, require a higher level of protection, electrical connections, and heat dissipation. To meet these needs, IC packages serve a crucial role. T...
Varistors are commonly employed in circuits for overvoltage protection, such as shielding electronic components from damage caused by excessive voltage. When the voltage in the circuit exceeds a prede...
IntroductionPart one of the Clipper Circuits briefed us on the two types of clipper circuits: positive and negative clipper circuits, and we dwelt deeply into the positive clipper circuits worki...
In typical scenarios, resistors and capacitors on a PCB are directly soldered onto the board surface. However, the embedded resistor and embedded capacitor process involve embedding resistors and capa...
Different from functional pads to establish electrical connections, non-functional pads are not connected to a trace on the layer they are on. They are typically used on inner layers of PCBs and are n...
What is Zero-ohm Resistor?A zero-ohm resistor, also known as a jumper resistor, is a specialized resistor with a nominal resistance value of zero ohms. It is commonly used in PCB design and other appl...
In power electronics, engineers sometime would like to reject part of the specified wave while allowing part of it to pass. This action requires the design of a special circuit known as a clipper circ...
Vias are the essential component of a multi-layered PCB. From a design perspective, a via consists of two main parts: the drill hole in the center and the pad area surrounding the hole, and the sizes ...
Metal core PCBs, also known as MCPCBs, incorporate a thermally conductive metal core, such as aluminum, copper, or stainless steel, instead of FR4. This metal core acts as a heat sink, efficiently con...
As printed circuit boards continue to shrink in size, the surface area available for wires and components is becoming more and more limited. In this case, cavity PCB becomes an effective solution.What...
IntroductionVarious electrical components are used to achieve various roles in a printed circuit board. Therefore, a good PCB designer should have a complete understanding of such components and what ...
As parts of the passive components, resistors are components that are designed to impede or restrict the flow of electric current. Resistors are non-polar components, meaning they do not have polarity...
Common PCB thermal management methods include using a heat sink, thermal pads, thermal vias, copper pour, and thermal relief. In PCB designs, thermal management methods can be implemented using a comb...
Black Core PCB is a special type of printed circuit board that features a distinct appearance and characteristics compared to traditional PCBs. It is named after the black substrate material used betw...
Capacitors are commonly used electronic components in modern circuits and devices. With a history and utility of over 250 years, capacitors are among the oldest electronic components that have been re...
Designing PCBs comes with various challenges, including undesirable breakouts due to drill wander, misalignment, and stress concentration. To address these issues, one effective technique is the use o...
How Important is Solder Mask Ink?Provides insulation protection;Acts as a safeguard against short circuits and corrosion;Enhances the reliability and durability of the circuit board;Ensures stable tra...
Counterbore holes are cylindrical with flat bottoms, while countersink holes are conical recesses designed to accommodate a screw or bolt. Both types serve to insert screws or fasteners, yet they offe...
Single-layer PCBs and double-layer PCBs are two basic types of boards that have only one or two layers of conductive materials over the substrate. When more routing space or signal integrity is requir...
