some hard plastics can handle temps at the 190 degree mark for a moment ... but I wouldn`t push it too long... I have never roasted delicate electronics in an oven... hope never to... but I have messed with temperature and plastics... so theory is sound... and a number of members have done such trials before with success (some not so successful...definitely keep in mind what they did wrong)... a heat gun and experience makes more sense to me though... rather than an oven...
