What is an advantage of boundary scan technology? - ANSWER ✓ Can perform
virtual in-circuit testing
What board feature may also be used as a test point? - ANSWER ✓ A wide
exposed conductor may be used as a test point
What is the numbering convention of layers of a PCB? - ANSWER ✓ Signal
layers, solder mask, then legend layers
How are datum features used? - ANSWER ✓ Position the printed board in relation
to a set of three mutually perpendicular planes
What are the names of the datum planes? - ANSWER ✓ Primary, secondary and
tertiary
How are grids designed? - ANSWER ✓ They are located with respect to a
minimum of two datums
What is the international standard for grids? - ANSWER ✓ 0.5mm or increments
of 0.05 mm grids
What does a grid system being basic mean? - ANSWER ✓ The intersection of the
lines has no tolerance
What are tooling holes? - ANSWER ✓ Very tightly toleranced unsupported holes
, What kind of tolerance is given to a tooling hole and why? - ANSWER ✓ A -0"
tolerance is specified so that the hole will never be too small to fit the pin
What is the common panel size in the US? - ANSWER ✓ 18" by 24"
Where can you place tooling holes on a densely populated design? - ANSWER ✓
Can put the tooling holes on the borders of the panel
What are more useful board excision techniques for high volume production? -
ANSWER ✓ Punching (or blanking) dies to excise boards from fab panels is more
efficient than other methods
How much does a Vscore cut from each side of the board? - ANSWER ✓ 1/3 of
the thickness of the board
What helps illustrate electrical function by means of symbols? - ANSWER ✓ The
schematic drawing
What are examples of active components? - ANSWER ✓ Transistors and diodes
What is important to know about a capacitor? - ANSWER ✓ It can be polarized or
unpolarized
What is important to know about a diode? - ANSWER ✓ It has an anode (+) and a
cathode (-)
What is the symbol for a photodiode? - ANSWER ✓ The same as an LED, but
with the arrows pointing in
What is the difference between an NPN and PNP transistor? - ANSWER ✓ The
emitter arrow points in towards the base for a PNP
When can you swap pins? - ANSWER ✓ When your gates are within the same
logic family
When can you swap gates? - ANSWER ✓ When your gates are all within the
same logic family and IC
