By 1663, King Charles II of England granted a charter to start a new colony on the North American continent; it generally established North Carolina's borders. He named it Carolina in honor of his father Charles I. By 1665, a second charter was issued to attempt to resolve territorial questions. In 1710, owing to disputes over governance, the Carolina colony began to split into North Carolina and South Carolina. The latter became a crown colony in 1729. Question: What year did King Charles II grant a charter to North America?

1663


question:
Passage: Often, through-hole and surface-mount construction must be combined in a single assembly because some required components are available only in surface-mount packages, while others are available only in through-hole packages. Another reason to use both methods is that through-hole mounting can provide needed strength for components likely to endure physical stress, while components that are expected to go untouched will take up less space using surface-mount techniques. For further comparison, see the SMT page. Question: Which type of construction makes components that use more space?
answer:
through-hole
