Intro Flashcards
Primary industries
Cultivate and exploit natural resources
Secondary
Takes outputs of primary and converts to consumer and capital goods
Tertiary
Service sector
Soft product variety
Only small differences among products
Hard product variety
When products differ substantially with few common parts
Unit operation
It is a single step in the sequence of steps required to transform the starting material into a final product
What are the types of shaping operations
Solidification processes- starting material is heated to liquid then cools and solidifies in geometry
Particular processing- material is a powder and powders are formed and heated into geometry
Deformation processes- starting material is deformed to shape
Material removal process
Types of surface processing
Cleaning- bothe chemical and mechanical
Surface treatments- mechanical
Coating and Thin film deposition- apply a coating
What surface processing has been developed to fabricate semiconductor materials into intergrated circuits
Chemical Vapor deposition
Physical Vapor deposition
Oxidation
Types of permanent assembly processes
Welding
Brazing
Soldering
Adhesive bonding
Mechanical assemby (eh rivets, press fitting, screw and expansion fits)
