An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of programmable read-only memory (PROM) chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply …

The rapid transfer of a voltage potential into a circuit or component. Depending on its sensitivity to ESD (Electrostatic Discharge), the overstress can permanently damage a component.

Etch Back or Etchback, is the controlled removal by a chemical and plasma process, to a specific depth of nonmetallic materials from the sidewalls of holes in order to remove resin smear and to expose additional internal conductor surfaces. Through-hole …

Small adjustments are made to normalized Gerber data it compensate for the amount of copper that will be etched from the production panel. This can vary depending on the copper weight and is determined by the CAM operator based on …

Etch Factor is the ratios of etch depth to the amount the resist is undercut during etching. In PCB fabrication process, copper has to be removed from solid copper sheets for realizing conductive traces. The most commonly way to remove …

Chemically removing the sidewalls of plated through holes in order to expose conductor areas on inner layers or a multi-layer PCB.

After an image pattern as been applied to a panel of copper clad fiberglass the unwanted copper is chemically etched away.

What’s Ethernet and Gigabit Ethernet?   In computer networking, Ethernet is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 …

What’s ETQFP?   ETQFP stands for Extra Thin Quad Flat Package (QFP).

Common solder alloy with low melting point. (63% Tin / 37%Lead)
