Brute force maximum speed for me, I used a heatgun.
Everyone used to do that in my old job.. Heat gun the part , they used to use the same YM chip.., lift it out, smack the PCB on the bench and all the solder would fall out of the holes, smack a new chip in , soldering got so fast could solder a 40 pin chip in 5 seconds easily. We could change a 40pin chip in like 30 seconds.
Funny story when I went for my first interview at my old job, had to change a chip... Boss was talking to another guy across the bench.. Like 1 min later... Done... Boss saying I want you to change that chip... I said I done it.. He said no you ain't where's the old chip... Said its there look... Boss said you just found that lay on bench.. Said no I bloody ain't, I just change the chip like you told me to... Then boss had to get a second opinion that I had actually changed it...fun times..not.
The second job interview at another company was even better... They actually manufactured a switchmode PSU, which I knew all about... Had to explain to 2 boss people how it works and what faults it suffers with... Have a guess how that went
I don't think manufactures really liked me much for some reason...
