Hi Zhenyu,

Thanks a lot for adding the adhesives information for mechanical structure for us. 

I also checked the numbers and they are correct. 

However, the spec of LOCTITE EA 9359.3 AERO (for PEEK-to-PEEK) mentions that the "service temperature" is 93 C, but your conclusion of 40 degree C is not affected. 

Cheers,

Yi

Hi Elke

The adhesives have been used to mount hybrid onto PEEK, PEEK to PEEK, Silicon to Hybrid.

They have the following glass transition temperatures

Araldite 2011 for Hybrid-to-PEEK

Tg ca. 45 degree C

LOCTITE EA 9359.3 AERO for PEEK-to-PEEK

Tg ~51 degree C

LOCTITE ABLESTIK 2902 for Silicon-to-Hybrid

Tg 52 degree C

TDR11-1100 for Silicon-to-Hybrid

Tg 85 degree C

I would avoid having temperature above 40 degree C.

Dear All,

as discussed in one of the Tuesday fSTAR meetings, we need to understand what adhesives have been used in the construction of the FST and what is their temperature rating.

This is really important to receive this information quickly as this will define how we go forward with the potential bakeout for the fixed target if needed.

Cheers elke
