What ratio should you never go beyond in terms of the length-to-width
ratio? - ANSWER--12:!
How do long, thin boards jeopardize conductor routability? - ANSWER--
Routing is primarily on the longitudinal axis and may cause crosstalk and
signal integrity problems
What is the benefit of copper balancing? - ANSWER--Uniform exposure to
the etching solutions
Addition areas of copper foil intended to draw copper in the plating bath
away from the fine conductor images; uniform plating distribution -
ANSWER--Plating Thief
What important effect is reduced as an output from copper balancing from
the center to either side in the laminated product - ANSWER--Bow and
Twist
What can help straighten a board that does not have proper copper
balance from bow and twist? - ANSWER--Mechanical features like heat
sinks and stiffeners
What thermal management technique transfers the heat down to a cooler
plan/surface? - ANSWER--Thermal vias
Thermal energy/heat that is transferred by electro-magnetic radiation
primarily in the infrared (IR) wave length - ANSWER--Radiation

How do large cores/large copper affect the reflow profile? - ANSWER--
Significant heatsink and impact the reflow of the solder surfaces
What is highly advisable to do when a board contains a metal core? -
ANSWER--Add a note on the Assembly Drawing
Why does 0402 equate to 0.03936~" x 0.01968~" not 0.04"x0.02"? -
ANSWER--Inaccurate round offs
What are the 3 vantage points of dimensioning? - ANSWER--Mechanical
Constraints Drawing (mating the PCB with the mechanical housing), PCB
Master Drawing, QA inspection criteria (ensure conformance of
manufactured product for intended usage)
For the relationship of the PCB to the Mechanical Constraints drawing,
what is critical to do to alleviate problems related to tolerance stackup? -
ANSWER--Using similar origins and coordinates, 0/0 origin (non-plated
tooling hole)
Unusual shaped boards are placed in an assembly array to do what? -
ANSWER--Maximize material usage and to facilitate board/array handling
The first two tooling features form the basis for what? The third tooling
features is a method for what? - ANSWER--Dimensioning system;
determining any angular movement of a material
