^ great response.
It takes a considerable Charge to feel it, Forget the exact value but it is in the HUNDREDs of Volts. Hummm CPUs and Memory run at less than 2 Volts.
ESD damage can be instant failure, or create a "waking wound" condition which is when the component is weakend and fails prematurely.
Generation of Electroc static charge DOES not require walking on a rug wearing a woolen shirt. Just walking (air moving across clothing - ANY Clothing) can generate a charge especially winter time with LOW humidity.
Infact pulling a piece of tape off of the roll can charge tape to realatively high electro-static charge. There is a table of different materials and the charge depends on how far apart the two materials are on the chart.
Touching a door knob may or may NOT discharge you completely, it may only equalize the charge, ie You have a 1kv charge touch a door knob and the door knob is now 500V and you still have +500 V. all depends on the mass a Door Knob is not a large mass of free electrons. Touch the door knob a 2nd time and nothing - Because you both have the same potential.
The ESD bag is to protect the device while it is IN the Bag, it will not discharge the static from your body, and offers NO protection once the device is removed.
Most would be surprised at what percentage of computer components are RMAed as DOA. Companies will not test for it as it is to costly so they just eat the cost, or should I say jack up the price to cover it.
Can any one say you did or did not damage the card - NO, to many unknown variables.
Just cross your fingers and hope.
