A type of printed wiring board used as an interposer when mounting semiconductors such as computer CPUs or memory.

The glass panels used in PDP TVs. PDPs are constructed from two thin glass panels between which rare gases are injected. Light and color can be emitted by adding a voltage to the gas and focusing the ultraviolet rays thereby produced onto fluorescent material.

An insertable package with external connecting pins arrayed in a grid pattern on its underside.

A blind via hole formed by exposure and development using a photomask and coated with a photosensitive insulating layer. This technique improves productivity because it allows batch formation of miniature diameter via holes.

Packages (modules) with base materials made of plastics such as glass epoxy.

A solder resist that is used on areas that do not require plating (i.e. areas excluding the pattern) in the patterning and plating processes. Ink or dry film are used as plating masks, and are removed after plating is completed.

A board consisting of a conductive wiring pattern formed on an insulated board via chemical means such as plating or etching, or via conductive paste.

An international quality standard developed by the "Big Three" US automakers. QS 9000 is based on the ISO 9001 standard, but also incorporates items specific to the automobile industry.
