01005s and Lead-Free Solder - Tiny 01005s are challenging for any electronics assembly process, but they're even more so if that process is lead-free

摘要

Remember when the 0402 was the smallest passive component you had to worry about? That part's dimensions - 1 millimeter long, 0.5 millimeter wide, and 0.35 millimeter thick - were cake compared with the latest chip to come off the reel, the 01005. An 01005 measures just 0.4 millimeter long, 0.2 millimeter wide, and 0.13 millimeter thick. A thousand 01005s weigh just 0.04 gram, and 16 of them can fit inside an 0402! The 01005 is also more expensive than its larger cousins. Whereas an 0402 costs approximately USD0.004 and an 0201 costs USD0.04, an 01005 costs USD0.45.
