SAC305 is a common medium-high-temperature solder commonly used in secondary reflow soldering. SAC305 has high conductivity and soldering strength, which can meet the usage requirements of most microelectronic products. The main factor affecting the soldering strength of SAC305 is the growth of intermetallic compounds (IMCs). IMCs nucleate and grow due to interface reactions during soldering and aging, and their brittleness may reduce the strength of the solder joints. SiC is a ceramic material with unique chemical stability and ultra-high melting point and possesses excellent electrical, mechanical, and thermal properties. Many studies have shown that SiC particles can be refined β- Sn and IMCs play a role in enhancing solder joints.

The Opposite of Falling Apart от titanically-
66 Части Завершенная история
WATTPAD BOOKS EDITION There are imperfect moments in every life-but sometimes, there are perfect accidents . . . What's the point of pretending nothing has changed when everything has? It's the last summer before college, and Jonas Avery knows he should be excited. Instead, he hides out at home, avoiding his friends, his family, and everything that resembles his old life. Because nothing will be normal again-because of The Accident, when everything started falling apart. Brennan Davis knows she needs to stand up and face her anxiety-the deep, dark, debilitating dread that rules her everyday life. Because what stops her from going out into the world and just living is going to get a whole lot worse. She's leaving for college in the fall, where she'll be confronted with even more to worry about. To get back up sometimes you have to fall down, hard . . . When Jonas crashes into Brennan-in a harmless, albeit embarrassing fender bender-the two teens connect in ways they never expected. As friends, they help each other overcome their biggest falls and faults, and soon discover that while love can't fix everything, it's sometimes a place to start. Sensitive, wry, and unabashedly authentic, The Opposite of Falling Apart isn't about finding perfection in another person or fixing the things we think are broken. Instead, Micah Good has penned an enchantingly honest novel about accepting the very pieces of ourselves that make us unique, whole, and undeniably human.
