看来对于陌生的名词,大家都不太愿意去动用搜索引擎,而是喜欢根据自己已知的知识来推断。呵呵
关于RoHS-5和RoHS-6,这确实是个很民间很不正式的说法,之前应该是起源于某些大公司的管控文件,后来大家就都这么说,但是现在基本上没人这么说了。这里给大家介绍一下:
RoHS6,是指该材料中,RoHS管制的6种有害物质全部都符合要求(低于限量)。
RoHS5,是指该材料中,铅含量高于1000ppm但是符合豁免条款,除铅以外的其他5种有害物质都符合要求(低于限量)。

Maximum reflow temperature is 235°C
RoHS-6
Product does not contain Cadmium (Cd), Mercury (Hg), Hexavalent Chromium (Hex-Cr), Polybrominated Biphenyls (PBB), Polybrominated Diphenyl Ethers (PBDE) Some internal connections may contain Lead used in high melting temperature solder (solder alloys containing more than 85% Lead Plating finish on component terminations is Lead-free.
Maximum reflow temperature is 245°C.

如果说根据这个的话,楼上的说法是正确的!
