Question: 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.

Answer: What's the minimum amount of copper a layer in a PCB can have to be considered "heavy copper"?

Question: Other regions host festivities of smaller extent, focused on the reenactment of traditional carnevalic customs, such as Tyrnavos (Thessaly), Kozani (West Macedonia), Rethymno (Crete) and in Xanthi (East Macedonia and Thrace). Tyrnavos holds an annual Phallus festival, a traditional "phallkloric" event in which giant, gaudily painted effigies of phalluses made of papier mache are paraded, and which women are asked to touch or kiss. Their reward for so doing is a shot of the famous local tsipouro alcohol spirit. Every year, from 1 to 8 January, mostly in regions of Western Macedonia, Carnival fiestas and festivals erupt. The best known is the Kastorian Carnival or "Ragoutsaria" (Gr. "") [tags: Kastoria, Kastorian Carnival, Ragoutsaria, , ]. It takes place from 6 to 8 January with mass participation serenaded by brass bands, pipises, Macedonian and grand casa drums. It is an ancient celebration of nature's rebirth (fiestas for Dionysus (Dionysia) and Kronos (Saturnalia)), which ends the third day in a dance in the medieval square Ntoltso where the bands play at the same time.

Answer:
Who holds an annual Phallus festival?
