It is legal to look for work while visiting Canada. Obviously, you should always tell the truth to the officer and state your purposes in the country. You would also need to prove to the immigration officer that the plan is to leave Canada within the maximum allowed time and that you will not work in the country without the proper work permit.
Dielectric materials for semiconductor chips. Dielectric material characterize with very low electrical conductivity (one millionth of a mho / cm), in which an electric field can be sustained with a minimal leakage. It can store electrical energy/charge.
Many materials are used to transit electrical energy. But those most frequently specified are copper, copper covered steel, high strength copper alloys, and aluminum. For more unusual applications conductors have been fabricated from pure nickel, pure silver, copper covered aluminum, and a host of metals, metal alloys and metal combinations. COPPER. Copper is by far the most widely used conductor material. Among its physical properties are high electrical and thermal conductivity, ductility, malleability and solderability, high melting point, and high resistance to corrosion wear and fatigue.
