An Edge Connector is the portion of a printed circuit board (PCB) consisting of traces leading to the edge of the board that are intended to plug into a matching socket. The edge connector is a money-saving device because it …

Electronic Data Interchange (EDI) is the computer-to-computer exchange of business documents in a standard electronic format, like Gerber (RS-274-X), Excellon, ODB++, .CAM, DXF, .DWG,  .pcbdoc, and etc. in PCB manufacturing industry. Technical standards for EDI exist to facilitate parties transacting …

EEPROM (also E²PROM) stands for electrically erasable programmable read-only memory (ROM) and is a type of non-volatile memory used in computers, integrated in microcontrollers for smart cards and remote keyless systems, and other electronic devices to store relatively small amounts …

The Electronic Industries Alliance (EIA; until 1997 Electronic Industries Association) was an American standards and trade organization composed as an alliance of trade associations for electronics manufacturers in the United States. They developed standards to ensure the equipment of different …

A displacement of bound charges in a dielectric when placed in an electric field.

Electrical Strength measures a PCB material’s ability to resist electrical breakdown in the PCB’s Z direction (perpendicular to the PCB’s plane). It is expressed in Volts/mil. Typical electrical strength values for PCB dielectrics are in the range of 800 V/mil …

What are Electrical Waveforms?   Technically speaking, Electrical Waveforms are basically visual representations of the variation of a voltage or current over time. This means that if we plotted these voltage or current variations on a piece of graph paper …

The process of depositing a conductive material from a plating source using the application of an electrical current. This is used for plating in the hole walls as well as adding plating the copper pattern.

Electro-less Gold Plating, or Electroless Gold Plating, is Electroless Nickel Immersion Gold (ENIG or Eni/IAu), also known as PCB surface finish Immersion Gold (Au), Chemical Ni/Au or Soft Gold, is a metal plating process used in the manufacture of printed …

The process of depositing a conductive material from an autocatalytic plating solution without the application of an electrical current. Used to apply a thin amount of copper prior to copper plating to improve the possible connecting in the hole walls. …
