+If the sample shatters while trying to mount it to the copper blocks it could be that you should try tightening each screw a little bit at a time in a criss-cross fashion (that is, try tightening screws just a little bit at a time starting in one corner, then crossing to the furthest corner and tightening that one a little bit).  It can be extremely frustrating to tighten the screws tight enough that the sample is secure, but not so tight that the substrate breaks.
+Another method may be to apply a little bit of indium directly do the sample's leads (using a wooden dowel to carefully push the indium to the lead, or by using soldering techniques as in the Hall measurements) as well as to the copper blocks.
+It is recommended that one should practice the procedure on an already broken or useless sample before trying on an important one.
