Click on the first letter of the term that you require wafer A
thin disk (or slice) of silicon on which many separate chips can
be fabricated and then cut into individual die. waste hierarchy:
The ranking of waste management options in order of
sustainability. waste management: Management of the collection,
recovery and disposal of wastes, including options for waste
reduction. waste minimisation: The reduction of waste at source,
by understanding and changing processes to reduce and prevent
waste. This is also known as process or resource efficiency.
Waste minimisation can include the substitution of less
environmentally harmful materials in the production process.
wave soldering A method of soldering components to printed
circuit boards by moving the boards over a continuously flowing
and circulating wave of molten solder in a solder bath. The
process permits precise control of the depth of immersion in the
molten solder and minimises heating of the board. SMDs are held
in place during wave soldering with a
