Oscilloscope Introduction   An oscilloscope, previously called an oscillograph, and informally known as a scope or o-scope, CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that graphically displays …

Refers to gaseous emissions from solids or liquids, usually caused by exposure to high operating temperatures and/or altitude (low external pressure). Outgassing may come from absorbed gas, from the vaporization of volatile contaminants, or from the breakdown of constituent materials. …

Terminal at which a component, circuit or piece of equipment delivers current, voltage or power.

Output Impedance is the ratio of change in output voltage to change in load current. All devices and connections have non-zero resistance and reactance, and therefore no device can be a perfect source. Power supply input and output impedance are …

Amount of power a component, circuit or system can deliver to a load.

Outsourcing in PCB field is an agreement in which one company hires another company to be responsible for a PCB related project completion. Outsourcing tasks, involving printed circuit board manufacturing, assembly, design, components, programming, functional testing and etc., to an …

Increase in printed circuit conductor width caused by plating build-up or by undercutting during etching.

What Is Overlap in PCB?   Overlap or Overlapping in printed circuit boards (PCBs) refers to some features cover some other features partly by going over their edge. Some common overlapping include pad overlap, carbon overlap and solder mask overlap. …

Condition that occurs when the load is greater than the system was designed to handle. (Load resistance too small, load current too high.) Overload results in waveform distortion and/or overheating. Overload protection – Protective device such as a fuse or …
