Propagation Delay is the length of time taken for a signal to reach its destination in printed circuit boards (PCBs). To keep a good high-speed signal quality from driver to receiver on a PCB is not an easy task for …

Prototype is an element of new product introduction (NPI), which involves building initial quantities, in short production runs, of an electronic product, like bare PCB and PCB assembly, for testing, as well as for design validation and manufacturability refinement. The …

Prototyping is an element of new product introduction (NPI), which involves building initial quantities, in short production runs, of an electronic product for testing, as well as for design validation and manufacturability refinement. The prototyping process involves nearly all aspects …

What’s PSON Package?   Plastic Small-outline No-lead (PSON) package is a SON package with a plastic small outline and no lead, with no lead extending beyond the package body. The contact pads are exposed and flush with the bottom of …

What’s PSOP?   Power Small Outline Package (PSOP) is a rectangular small outline IC (SOIC) package that integrates a copper heat slug in its plastic body. The die is attached to this heat slug, increasing the chip’s ability to dissipate …

Polytetrafluoroethylene (PTFE), also called Teflon, is a synthetic thermoplastic fluoropolymer that has excellent dielectric properties at microwave frequencies. When design high frequency PCBs at microwave frequencies, the key characteristics that define PCB laminate performance for microwave/RF printed-circuit boards (PCBs) include dielectric …

What is an Electric Pulse?   An Electric Pulse is a burst of current, voltage, or electromagnetic-filed energy. In practical electronic and computer systems, a pulse may last from a fraction of picosecond up to several seconds or even minutes. …

What’s Phys­ical Vapor Depos­ition (PVD)?   The term Phys­ical Vapor Depos­ition (PVD), sometimes called Physical Vapor Transport (PVT), which covers spe­cific pro­cesses used in thin film tech­no­logy. In all cases, it refers to vacuum-based coat­ing pro­cesses that use phys­ical meth­ods …

Printed Wiring Board(PWB) is the same as Printed Circuit Board (PCB).

What’s QFN Package?   Quad Flat No Leads Package (QFN) is a very small square-shaped or rectangular surface-mount plastic package with no leads. It is basically a Quad Flat Package (QFP), except for the absence of leads protruding from its sides. …
