Not current, voltage. Depends on humidity, what kind of rug you are walking on, what kind of shoes you have, what kind of underwear you are wearing and whether you have stroked your cat lately. If clothes cling together when they are removed from your clothes dryer then you have conditions ripe for static production.
Any static potential greater than about 3 volts is sufficient to fry certain chips. But if you ground yourself to the frame of the device you are working on before you touch the device you are probably not going to damage it. Or wear a static discharge bracelet that is connected to the frame of the device.
If you get a tingle when you touch the frame for the first time you are in danger of damage. Ed Fair
