[EX Q]: The printed circuit board industry defines heavy copper as layers exceeding three ounces of copper, or approximately 0.0042 inches (4.2 mils, 105 m) thick. PCB designers and fabricators often use heavy copper when design and manufacturing circuit boards in order to increase current-carrying capacity as well as resistance to thermal strains. Heavy copper plated vias transfer heat to external heat sinks. IPC 2152 is a standard for determining current-carrying capacity of printed circuit board traces.
[EX A]: What's the minimum amount of copper a layer in a PCB can have to be considered "heavy copper"?

[EX Q]: Following the '69 season, the club posted winning records for the next few seasons, but no playoff action. After the core players of those teams started to move on, the 70s got worse for the team, and they became known as "The Loveable Losers." In 1977, the team found some life, but ultimately experienced one of its biggest collapses. The Cubs hit a high-water mark on June 28 at 4722, boasting an 8 12 game NL East lead, as they were led by Bobby Murcer (27 Hr/89 RBI), and Rick Reuschel (2010). However, the Philadelphia Phillies cut the lead to two by the All-star break, as the Cubs sat 19 games over .500, but they swooned late in the season, going 2040 after July 31. The Cubs finished in 4th place at 8181, while Philadelphia surged, finishing with 101 wins. The following two seasons also saw the Cubs get off to a fast start, as the team rallied to over 10 games above .500 well into both seasons, only to again wear down and play poorly later on, and ultimately settling back to mediocrity. This trait became known as the "June Swoon." Again, the Cubs' unusually high number of day games is often pointed to as one reason for the team's inconsistent late season play.
[EX A]: During what decade did the Cubs become known as "The Loveable Losers"?

[EX Q]: All of the state frequently experiences temperatures above 100 F (38 C) or below 0 F (18 C), though below-zero temperatures are rare in south-central and southeastern Oklahoma. Snowfall ranges from an average of less than 4 inches (10 cm) in the south to just over 20 inches (51 cm) on the border of Colorado in the panhandle. The state is home to the Storm Prediction Center, the National Severe Storms Laboratory, and the Warning Decision Training Branch, all part of the National Weather Service and located in Norman. Oklahoma's highest recorded temperature of 120 F (49 C) was recorded at Tipton on June 27, 1994 and the lowest recorded temperature of 31 F (35 C) was recorded at Nowata on February 10, 2011.
[EX A]:
What parts of Oklahoma rarely see below-zero temperatures?
