Plating on a PCB refers to the electrochemical process by which a metal is deposited onto the surface of the circuit board, and inside the plated through-holes. PCB plating may be defined as following: Via Plating: the process of filling …

Plating Resist is a kind of alkaline- or acid-resistant ink material applied as a covering film on an copper area of printed circuit boards (PCBs) to prevent plating on this area. LPI (liquid photo Imageable) versions are available in the …

A Programmable Logic Controller (PLC) or programmable controller is an industrial digital computer which has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, or robotic devices, or any activity that requires high reliability control …

What’s PLCC Package?   Plastic Leaded Chip Carrier (PLCC) is a four-sided plastic SMT chip package that has “J” leads around its periphery. These “J” leads occupy less board space than the gull-wing leads that other packages like the SOIC …

What’s PMCP?   PMCP -Power Mount Chip Package is a variation of WLCSP (Wafer-Level CSP) for MOSFET power devices made by Panasonic. Panasonic provides a diverse lineup including new ultra-small PMCP with high heat dissipation. MOSFETs for Load Switch features industry …

What’s PNP Transistor?   PNP Transistor is a type of transistor in which one n-type material is doped with two p-type materials. It is a device that is controlled by the current. Both the emitter and collector currents were controlled …

A Pogo Pin or Spring-loaded Pin is a type of electrical connector mechanism that is used in many modern electronic applications and in the electronics testing industry. They are used for their improved durability over other electrical contacts, and the …

What is Polarity?   In electronics, Polarity indicates whether a circuit component is symmetric or not. Polarity is a very important concept, especially when it comes to physically building circuits. Whether you’re plugging parts into a breadboard, soldering them to …

A component which must be connected in correct polarity to function and/or prevent destruction. Example: Electrolytic capacitor.

What Is Polygon Pour?   A Polygon Pour is a group design object that is made up of simpler primitive objects. Polygon pours are used to create a solid or hatched (lattice) area on a PCB layer, using either Region …
