A barcode or bar code is a method of representing data in a visual, machine-readable form. In PCB and assembly manufacturing, customers always require printed or laser barcodes on printed circuit boards. MADPCB uses CO2 laser to burn through the …

Bare board, also called bare PCB, blank board, or blank PCB, which is a completed printed circuit board without any components soldering on it.

A drilled hole can be either plated or unplated. The walls of a plated hole are called the via barrel. This creates a connection between the top of the board, the inner layers (if present) and the bottom of the …

A DC voltage source containing two or more cells that convert chemical energy to electrical energy.

A unit of signaling speed equal to the number of signal events per second. Not necessarily the same as bits per second.

Bare Board Test (BBT) –Electrical test of unpopulated PCB.

Beam Lead is a metal beam (flat metallic lead which extends from the edge of a chip much as wooden beams extend from a roof overhang) deposited directly onto the surface of the die as part of the wafer processing …

A Bed of Nails is used as part of an Electrical Test for bare boards at the final stage of PCB manufacturing. A frame is made that will hold test pins that match up with the connection points on the …

The BeiDou Navigation Satellite System (BDS) is a Chinese satellite navigation system, and which is also the third mature satellite navigation system after GPS and GLONASS. The BDS is composed of three parts: space segment, ground segment and user segment. …

What Is Flex Bend Radius?   Bend Radius (r), or Bending Radius, is the minimum degree one can bend a flexible printed circuit (FPC) without damaging it or shortening its life. The smaller the bending radius, the greater is the …
