A type of transmission line configuration which consists of a conductor over a parallel ground plane, and separated by a dielectric.
A destructive test procedure in which a section of specimen it cut and removed for close examination.
A deposited or plated thin metallic film used for its protective or electrical properties.
The contour or shape of molten solder as formed by surface tension forces in turn controlled by wetting.
The temperature range over which the solder alloy melts .An alloy with a single melting point, rather than a melting range, is known as a eutectic alloy .
A metal electrode leadless face surface mount component that is round with metallic cap terminations.
A condition existing in the base laminate in the form of discrete white sports or crosses below the surface of the base laminate, reflecting a separation of fibres in the glass cloth at the weave inte...
The statistical mean average time interval, usually in hours, that may be expected between failures of an operating unit. Results should be designated actual. Predicted or calculated.
Moulded Carrier Ring. A tape of fine-pitch chip package named for the method of supporting and protecting the leads. The leads are left straight; the ends of the leads are embedded in a strip of plast...
A hole size equal to the specified hole size before plating, plus the manufacturing tolerance, less twice the minimum plating thickness.
An accurately scaled pattern which is used to produce the printed circuit within the accuracy specified on the master drawing.
A document that shows the dimensional limits or grid locations applicable to any or all parts of a printed board(rigid or flexible),including the arrangement of conductive and non-conductive patterns ...
A document showing dimensional limits and grid locations for all parts of an assembly to be fabricated. It includes the arrangement of conductors and non-conductive patterns and the size, t...
A material applied to enable selective etching, plating or the application of solder to a printed circuit board.
The distance between the reference edge of a flat cable and the nearest edge of the first conductor.(See also Edge Spacing)
The minimum metal width, at the narrowest point between the circumference of the hole and the outer circumference of the land. This measurement is made to the drilled hole on internal layers of multi-...
