What is Noise in Electronics?   Noise (electronics) is an unwanted disturbance in an electrical signal. Noise generated by electronic devices varies greatly as it is produced by several different effects.   In communication systems, noise is an error or …

Also see Legend or Silkscreen. This is applied to the circuit board to identify components and other key information on the bare circuit board.

Non-Volatile Memory (NVM) or Non-Volatile Storage is a type of computer memory that can retain stored information even after power is removed. Examples of non-volatile memory include flash memory, read-only memory (ROM), ferroelectric RAM, most types of magnetic computer storage …

A land on internal or external layers, not connected to the conductive pattern on its layer of a PCB.

Non-wetting is a PCB soldering defect that occurs when molten solder fails to bond with the pads on PCB board, or solder may not adhere to components’ terminals.

What Is NOR Flash?   In NOR Flash, each cell has one end connected directly to ground, and the other end connected directly to a bit line. This arrangement is called “Not OR (NOR) Flash” because it acts like a …

New Product Development (NPD) and New Product Introduction (NPI) are the processes of bringing a product or service from inception to market. Pre-release activities from ideation until the approval for production of a new product concept is generally referred to …

New Product Introduction (NPI) is an early product life-cycle process service to assist OEMs in achieving cost-effective, quick-to-market and quick-to-volume production. The NPI process includes technology selection, design and development engineering services, test and material strategies, design for manufacturability and …

What’s NPN Transistor?   NPN Transistors are a type of bipolar transistor with three layers that are used for signal amplification. It is a device that is controlled by the current. A negative-positive-negative transistor is denoted by the abbreviation NPN. …

Non-Recurring Expense (NRE) is any type of onetime costs related to the PCB manufacturing and PCB assembly services. These costs will vary but not limit to Set-up cost (upon some limits) and E-test jig (fixture) cost.
