- One point people have seemed to miss is that if the case and leads get very
- hot (ie hot enough to melt solder) then it is likely that the silicon has
- got hotter than this, say at a cae temp of 200C a junction temp of 250C.
- Now as every engineer who uses transisitors, regulators etc (I know these things
- may be alien to you digital boys :-) ) you reckon that your device will stop
- working at a junction temp of 150C or a little more. So if you are
- melting solder with your ics than they arent doing what they ought to...
