a tip from me to unsolder a chip:
use the soldering iron and a vaccumpump to delsoder the pins
when all free then use a heatgun and heat the pins with it.
the chip falls out no force needed.....  maybee you must
drop the edge of the board a bit on the table....
no missing pins and they are straight. |

Thanks but too long time method. You pumped 300 or more pins ? I only use heatgun with careful using metal screwdriver.
