  1. Polyimide joint under tension in 50% HF • Goal: to observe effect of HF solution on PI-E joint under tension • Things to look for: • Destruction of polyimide tubing • Stretching/deforming of joint • Wire damaged or breaks or pulls out

  2. HF + tension setup: • 100 grams tension • (not shown: polyethylene cover on HF) camera “tension plate” Wirejoint in pool of 50% HF Clip, pulley, weights Polyethylene block

  3. 76 hours 104 hours 120 hours 126hours 144 hours

  4. Closeup of joint:

  5. Conclusions: • HF attacks glue from ends, also forms bubbles • Wire slips out through softened glue, knot gets tighter • Possibly some stretching/shrinking
