Does anyone know where electronic component package standards are published?

Q. I'm looking for some sort of reference that illustrates and dimensions electronic component standards. Like SOIC, DIP, PLCC. I need to create CAD models of various components so I would like to find drawings of all of the most common EE packages. Does anyone know where to look? Thanks.

A. http://www.jedec.org

They are *the* authority.

Click on "Free Standards", then register (for free), then you can browse all the standards for everything you mentioned (and then some).

Q. I would like to buy an electronic eqipment vallued aroound 300 CAD online from the US to Toronto. How I have to pay import duty

A. It depends on how the product is shipped.

If its via standard USPS (United States Postal Service), then Canada Post will charge you when you collect the parcel and tack on an additional $5 handling fee.

Some courier companies will have a customs broker pay the CRA on your behalf. They will then invoice you for a customs brokerage fee, and the duty.
