从表面看好象是G10等级的低温封装要求。不知道对不对，水平有限作者: jiangling 时间: 2007-11-6 17:24
还没见过，对不起作者: dnicp 时间: 2007-11-6 18:25
这个是金属材料么？作者: lwlbrandy 时间: 2007-11-6 21:57
Cryogenic G10 - CR
IPC GRADE / CRYOGENIC GRADE G10 is an electrical and mechanical grade of glass cloth laminate impregnated and cured with a non-brominated epoxy resin. Also referred to as G10-CR, G10 CR conforms to Mil Spec Mil-I-24768/2 Type GEE . G-10 CR contains no halogens and can be used in nuclear and space applications. G10 CR has been tested in accordance with NIST G10CR process specification for materials used in cryogenic applications. G10 CR Material is RoHS Compliant per Directive 2002/95/EC.
Cryogenic G10 is used in applications were flame retardency isn't an issue. Space applications such as sattelites require stringent temperature requirements in sub zero environments and have very little risk of fire. G-10-CR is an excellent choice when working with liquid nitorgen and cryo lab applications.作者: man_198 时间: 2007-11-7 12:23
谢谢诸位师傅！
