Hi Guys,
So I just started looking in to desoldering eeprom chips ( Motorola etc )
What is the safe temperature before they get fried ?
Is this technique good enough ...
1. Using masking tape - tape around eeprom to protect other smd's
2. Turn on Hot Air - let it preheat to 420C ?
3. add some liquid flux to the legs
4. with circular move - move hot air nozzle around the eeprom
4. lift the eeprom
What temperature ?
What nozzle something tiny or something like 8mm is good enaugh
What is the safe temperature ?
How long it should take before I can lift the eeprom ?
i'm wondering if I should maybe put a tiny heat sink on the eeprom to help cooling ?
Or maybe I should use chip quick for desoldering at lower temp ?
Or spray the IC smd with Freeze in a can to protect from overheating ? but Can't the cold temperature kill it as well ?
Thx
