I resemble this problem,

having dealt with on various levels of equip for the last 15 years,
all I can say is experience helps but good prep is best.
If a break in the carrier plastic exists then add/glue another layer of
reinforcing on the outside if possible. kapton tape helps.
excess can be scraped away after dry.
try not to move joint while drying.
vial tends to dry up, rejuvenate with acetone.
tricky ones can use fine gauge copper embedded/painted over.
