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
还没见过，对不起
这个是金属材料么？
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.
谢谢诸位师傅！
