I've worked a couple of years at an electronics productionfactory, so I had to follow an IPC course, and do some exams as well. So I know a fair bit about ESD protection, and how to modify and repair SMD boards that live up to the IPC standards. ESD safety is of vital importance. It's not that surface mount semiconductors go dead immediately after an electrostatic discharge, but they can get damaged enough to decrease the life span to just a couple of years. Especially SMD stuffed boards are very fragile. Even SMD resistors are easily damaged by ESD.
So, there are guidelines to follow, to avoid ESD.
(well....Now I've started...let's bring this to light, there are probably quite a lot of people here that don't know about ESD protection)
Usually, the humidity in an ESD room is controlled (40-60 percent). Paper and electrostatic plastic materials aren't allowed in such a room, unless they're put inside electrostatic dissipative plastics (like PinkPoly). The floor and table surfaces should have got a resistance of 1meg-10 meg to ground (a straight connection to ground is very dangerous). The same goes for closets, shelves, seats and other furniture. The tools used for production should be ESD safe. (makes sense, but think a while about a screwdriver : is that plastic handle ESD safe ? Or is it an isolator ?!?)
People inside the room should wear ESD protective clothing. This applies to ESD safety shoes, which should connect the person wearing them, via the floor, to ground. This also applies to the mandatory labjacket/shirt, which should cover the T shirt or sweater the person is wearing. This jacket is made from cotton, but is woven with some kind of carbonimpregnated thread. So, this jacket forms actually a cage of Faraday.
But the most important thing : When handling PCA's (Which is a stuffed PCB) you should ALWAYS use a wristband, connected to ground (again, via 1 meg resistance).
A side note for the 1 -10 meg. This value is used to slowly discharge everything from electrostatic charge.
So, actually, ESD protection is very simple in theory.
1. Everything in an ESD safety room should be discharged slowly, and electrostatic charging should be avoided at all times.
2. Isolators should be avoided in an ESD safety room.
Now, back to the video :
I'm mainly referring to the way they handle the PCA's by hand. Have a look at the woman who's checking the PCB by computer. She isn't wearing ESD protective clothes, but she doesn't use ESD wristbands either .....
And this surprises me a lot. They use state of the art X-ray equipment to check the PCA's. This is a very expensive tool, but then they don't bother to handle the materials with care..... ???
