|| || || || || || || ||
What do performance classes reflect? - ✔✔Progressive increases in sophistication, functional
|| || || || || || || || || || ||
performance, and frequency/intensity of inspection or stress testing || || || || || || ||
What are the three performance classes? - ✔✔1-General Electronics 2-Dedicated Service 3-
|| || || || || || || || || || ||
High reliability
||
Who is the end user? - ✔✔The end user is the individual or agency that contracts the printed
|| || || || || || || || || || || || || || || || || ||
board or assembly to be designed and manufactured
|| || || || || || ||
Who determines the class of a product? - ✔✔The end user
|| || || || || || || || || ||
What would be in class 3 performance? - ✔✔Military, medical, etc.
|| || || || || || || || || ||
What is ambient temperature? - ✔✔The surrounding environment that comes into contact
|| || || || || || || || || || || ||

|| ||
What do producibility levels tell us? - ✔✔Increasing complexity of tooling, materials, and
|| || || || || || || || || || || || ||
processing. Yields increase as costs decrease, etc. || || || || || ||
What increases with each producibility level? - ✔✔Sophisitication
|| || || || || || ||
What is the zaxis aspect ratio? - ✔✔Ratio between the nominal thickness of the board and the
|| || || || || || || || || || || || || || || || ||
smallest drill size. || ||
, What is the most important special consideration in terms of electrical functionality that a
|| || || || || || || || || || || || || ||
designer must consult the EE? - ✔✔Special keep out or keep in areas of the board.
|| || || || || || || || || || || || || || ||
Where should high frequency circuits be placed? - ✔✔NEar the connector
|| || || || || || || || || ||
Where should filtering caps be placed? - ✔✔Near the source of power/gnd (at the connector)
|| || || || || || || || || || || || || ||
What is least important to route in analog circuits? - ✔✔Power and ground
|| || || || || || || || || || || ||
What is a major consideration for component placement? - ✔✔Will backwards compatibility
|| || || || || || || || || || || ||
be necessary?
||
What is Ohm's law? - ✔✔V=IR
|| || || || ||
What is an important basic rule for a designer of a board? - ✔✔Terminate unused logic pins
|| || || || || || || || || || || || || || || || ||
with a pull-down or pull-up resistor.
|| || || || ||
What product safety testing regards flame retardants? - ✔✔UL 94
|| || || || || || || || ||
How thick is half ounce copper? - ✔✔0.7 mils (17 um thick)
|| || || || || || || || || || ||
What is the subtractive process? - ✔✔Unwanted copper is etched away
|| || || || || || || || || ||
