Synchronous Dynamic Random Access Memory (SDRAM) is a relatively new type of DRAM, which synchronizes itself with the CPU‘s bus and is capable of running at higher clock speeds than conventional memory.

Output winding of a transformer. Winding that is connected to a load.

Selective Gold indicates that a specific area in the interior of the board would be plated. This does not include gold fingers.

The tendency of leads to center themselves on solder pads due to the surface tension of liquid solder.

A Semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave in the opposite way. Its conducting properties …

Sequencing is one of process planning, which refers to arrangement of components in their order of placement sequence and to prepare tape and reel by a sequencer. Sequencing is an important and integral part of effectively operating a printed circuit …

Sequential Lamination is an additive PCB fabrication process of sequentially building up the PCB construction by adding layers of dielectric material and copper. Layers are built upon subcomposites (/subparts), which are structures composed of alternating copper and dielectric levels enclosed …

What Is A Series Circuit?   A Series Circuit is a path for transmitting electric current, and which comprises a path along which the whole current flows through each component. Series circuits are sometimes referred to as current-coupled or daisy …

What Is A Seven Segment Display?   A Seven Segment Display, or 7-Segment Display, is a form of electronic display device for displaying decimal numerals that is alternative to the more complex dot matrix displays. These displays are widely used …

A condition occurring during etchback in which the dielectric material, in contact with the foil, is incompletely removed although acceptable etchback may have been achieved elsewhere.
