Maybe I've worked on too many really crappy boards with barely enough pad round the hole and hair thin tracks?
Some of them, the pads would lift if you merely looked at the cross-eyed, which made changing DIP ICs extremely challenging. Even Dremmeling the legs off was pretty dicey as if the cutoff wheel snagged the leg, it usually lifted the pad, so one had to cut into the body just enough to steady the leg while still letting it be pulled free when you heated the joint.
I must admit I have ran into some like that.
Barco & Bosch were the worst offenders.
Their boards looked beautiful,compared to,say,Sony,but they were sods to work on.
For some unknown reason,they often made the holes so tight that component leads were an interference fit.
That made it easy to wreck the hole (especially plated through ones).
Sony used good sized holes & generous pads,allowing for easy replacement of parts,in both their Studio & Domestic stuff,
NEC were also mostly good that way,although in one RF board they had a relay with about 20 pins,15 of which were to secure it to the board,& connect to the ground plane.
Braid didn't work,a Pace Desoldering Station didn't work.
Eventually,we found there was enough space to run a "Stanley knife" blade between the relay & the PCB,cutting off all the pins.
With the relay removed,it was easy to remove the pins.
It wouldn't have been possible if we had needed to salvage the relay!
