What Is A Cut-Tape?   Cut-Tape or Cut Tape is a strip of components cut off from a full tape and reel. While tape and reel is long, continuous, and wound up in a reel, and can be cut into …

Condition when an active device is biased such that output current is near zero or beyond zero.

When a repeating wave rises from zero to a positive maximum then back to zero and on to a negative maximum and back to zero it is said to have completed one cycle.

Used in photoplotting. D-Code consists of X,Y coordinates supplemented by commands that define where the PCB image starts, what shape it will take, and where it ends. In addition to the coordinates, Gerber data contains aperture information, which defines the …

What’s D2PAK?   The Double Decawatt Package, D2PAK, SOT404, or DDPAK, standardized as TO-263, refers to a semiconductor package type intended for surface mounting on printed circuit boards (PCBs). The TO-263 is designed by Motorola. They are similar to the …

What’s D3PAK?   Decawatt Package 3 (D3PAK) is a bigger version of the D2PAK package. Just like the D2PAK (and the DPAK, the D2PAK’s predecessor), the D3PAK is a surface-mount plastic-molded package intended for high-power discrete devices. Decawatt Package 3 …

Digital to Analog Converter (DAC).

The Date Code is added to the copper or silkscreen of the PCB during the manufacturing process. The date code shows the week and year that PCB was made.

A Datum is used in PCB design files to mark the point of the axis or plane used as the origin of the PCB design.

What’s DBC (Direct Bonded Copper) in Ceramic PCB?   DBC (Direct Bonded Copper) is a process in which copper and a ceramic substrate are directly bonded. DBC ceramic substrates have been proven for many years as an excellent solution for …
