What’s EMI?   Electromagnetic Interface (EMI) is electromagnetic energy that disturbs the signaling in an electronic device through radiation, electrostatic coupling or induction. The disturbance may degrade the performance of the circuit or even stop it from functioning. In the …

EMIC (Electromagnetic Interference Control), or EMI Control, is the process of making PCB design changes or adjustments of signal or noise levels.

What is an Emitter in Transistor?   Emitter in a transistor is the heavily doped region as compared two base and collector, to supply charge carrier to the collector via the base. Transistors are composed of three parts: Base: the …

Electronics Manufacturing Services (EMS) is a term used for companies that design, manufacture, test, distribute, and provide return/repair services for electronic components and assemblies for original equipment manufacturers (OEMs). The concept is also referred to as Electronics Contract Manufacturing (ECM).

The high-precision, close-tolerance housings which encase electronics products and assemblies. Typically constructed from various metals and plastics, enclosures are an integral part of electronics products and are critical for protection, environmental control, interconnection, compactness and multi-unit integration.

Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG). is a PCB surface finish, similar to ENIG, but applies palladium over the nickel prior to the application of the gold. This prevents any problems of corrosion between the nickel and gold and …

What is Enhancement-mode MOSFET?   MOSFETs are three terminal devices with a Gate, Drain and Source and both P-channel (PMOS) and N-channel (NMOS) MOSFETs are available. The main difference this time is that MOSFETs are available in two basic forms: …

Electroless Nickel Immersion Gold (ENIG) is a very thin amount of Gold applied over Nickel. The nickel is plated onto the copper prior to the application of Gold and acts as a barrier to prevent the Gold and the Copper …

Epoxy Resins and Polyurethane in PCB laminate, Prepreg and RCCs are used for protection in thickness. These systems generally two liquid components when mixed climb quickly in viscosity until fully cured. They are designed to protect and insulate the printed …

Epoxy Smear: All you need to know about it Epoxy resin which has been deposited on edges of copper in holes during drilling either as uniform coating or in scattered patches. It is undesirable because it can electrically isolate the …
