Printed by the photo plotter to be used for making the copper pattern. Also used for making the patterns for soldermask and silkscreen.

Pick and Place all you need to know about it Pick-and-Place (PnP), also called centroid coordinate, or XY, is used by the machine for automatically pick up components in SMT feeders and place them onto a printed circuit board. This …

What’s Piezoelectric Crystal?   Piezoelectric Crystal material generates a voltage when mechanical pressure is applied and conversely will undergo mechanical stress when subjected to a voltage. Also see Piezoelectric Effect.   Types of Piezoelectric Materials   There are a variety …

What is the Piezoelectric Effect? Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. i.e. The production of a voltage between opposite sides of a piezoelectric crystal as a result …

A terminal on a component, whether SMT or through-hole. [Derived from its physical shape on through-hole components, which predated SMT. Also called lead.

In printed circuit boards, Pitch is the center-to-center distance between two adjacent holes, BGA pads, part connectors, or other SMD pads. How to Route the Traces with Limited IC Pitch Size? There is a wide array of ICs that are …

Plane, also called copper pour, is a solid copper layer, which is typically used for grounding or power in a printed circuit board design.

Plasma Etching is a process used to remove copper from a PCB panel for special RF materials that cannot be processed with standard etching procedures.

What’s a Plastic Film Capacitor?   A Plastic Film Capacitor is a capacitor that uses plastic film as the dielectric and aluminum or zinc as the electrodes to store electric charge.   What are Film Capacitors?   Film capacitors can …

What Is Plastic Leaded Chip Carrier?   Plastic Leaded Chip Carrier (PLCC) is a four-sided “J” leaded plastic body package. PLCC is a form of SMD integrated circuit (IC) package that can be used to be enable ICs to be …
