Dear Yi and Zhenyu,
	Could one or both of you please order some Littelfuse # 01220087Z (Mouser has 
stock, 84 cents each, 
https://urldefense.com/v3/__https://www.mouser.com/ProductDetail/Littelfuse/01220087Z?qs=*2Fha2pyFaduglErFCB38n3htdBYhndPrY4k2JWosNk8ORS1jEraEYXw*3D*3D__;JSUl!!P4SdNyxKAPE!V3xdOkTruG4VzRQirTwQLvHJK3hFVDssHTjK_gul0YsV3ws-wDDmrQl-94G_9KuV283L_mo$  
) to evaluate for use in connecting the short ground wire from T-board to the 
cooling tube on each module?
	Nominally it is meant to give a nice solid electrical connection to a 1/4 inch 
fuse terminal, it shoud similarly snap nice and solidly onto the cooling tube. 
Hopefully there is a short straight place where it can be put.
        Sincerely,

                Gerard
