Фонбет Чемпионат КХЛ
If you go see some classical music, no one tells you you’re supposed to sit completely still during the music and never clap between movements. If you go to a Thai restaurant, they might provide chopsticks, but they don’t tell you you aren’t supposed to use them. If you go to a rave, no one tells you that it’s been 20 years since anyone called them “raves”. And how much knowledge is needed to appreciate cricket or American football or—god help you—Australian rules football?

It’s actually a two level structure, the controller die is out of view on the lower layer (but we can see some gold contacts deep down that it presumably connects to). The quartz crystal is a rectangular sheet with a slightly textured surface and rounded corners, with a gold electrode covering most of the top and bottom surface. One side of the crystal hangs over a small rib on the edge of the package but doesn’t seem to touch it (maybe this is an end stop to keep it from breaking if dropped?) while the other side is attached to a pair of gold contacts on the ceramic package with a conductive adhesive of some sort, probably silver filled epoxy.，详情可参考手游
