Health Advisory
The specific surroundings within which an organism, a species, or a community lives. The surroundings include physical factors such as temperature, moisture, and light together with biological factors such as the presence of food or predator organisms. The term can be employed to define surroundings on almost any scale from marine habitat, which encompasses the oceans, to microhabitat in a hair follicle of the skin.
Hardwired Array Logic
The time taken by certain materials to lose half their strength. The time required for half of the atoms of a radioactive element to undergo decay. The time required for the elimination of one half a total dose from the body.
A class of simple hydrocarbon derivatives in which bromine, chlorine and fluorine are substituted for some or all of the hydrogen atoms. These compounds are used mainly as fire-extinguishing gases, the two best known being Halon 1211 (CF2BrCl) and Halon 1301 (CF3Br). The chemicals are long-lived in the troposphere and are implicated in the depletion of the ozone layer.
A mechanical device attached to an automatic testing or finishing machine which loads the parts one at a time.
Hazardous Air Pollutant
A photoplate coated with a relatively hard, non-emulsion coating that can be selectively etched to produce a photomask. Popular hard surface materials are chromium, chromium oxide, and iron oxide.
The physical components of a computer or an electronic system - as opposed to software, which is the term used to describe the programs and instructions for a computer.
Hot Air Solder Leveling
Process to deposit uniform coating of solder on PCB's.
- Hazardous Waste Managemente
