3M ESD Static Dissipative Table Mat: How do I ground my ESD mat to avoid shocking computers?

Thu, 06 Dec 2012 10:53:05 -0700

I wouldn't be posting if hours of searching yielded the answer(s) I need. My apologies if this is common knowledge. I searched through questions here and was unable to find anything helpful for my situation. To my question:

I purchased an ESD mat from a local shop today and a piece that snaps to the mat was included. As well as connecting a wrist strap to this piece, it has a 15' tail with a metal ring at the end for grounding. How exactly do I ground with this metal loop? Do I connect to 'the ground hole' on a wall outlet? If so, how? Also, if this is NOT an option in my environment how would I ground? I'm trying to avoid running a copper cord out a window attached to a stake that is driven into the ground...

iPhone 4: Where are the iPhone 4 antennas' feeding and grounding points?

Wed, 02 Mar 2011 04:18:53 -0700

What sort of antenna does iphone 4 employs? Is it an IFA (inverted F antenna)? I tried to find the feeding and grounding points, particularly for the wireless antenna (WiFi, Bluetooth and GPS).

Usually and IFA has a feeding point somewhat in the middle. Unfortunately, I cannot find it. There seems to be a feeding point close to the top slit.

Is it possible then to achieve dual-band behavior? How many grounding points are there, and where?

thanks

iPod 5th Generation Video: How do you repair torn ground foil on the logic board?

Thu, 03 Feb 2011 22:21:55 -0700

Just received the new logic board for my 5.5 and was able to take everything apart following the how-to document. My only issue was that the Foil removal from the old bard and re-install on the new board was not discussed...or I missed it. Of course I was not careful enough and the the thin lead that goes to the case for ground has torn.

How do I fix it?

As a dosumentation suggestion:

Looks like either here:

Installing iPod 5th Generation (Video) Logic Board

or at Step 19 (Or new Step 20), we need to instruct on how to remove said foil.

I found that after mistakenly pulling the ground tab piece (which casued the foil break) that peeling up on the round (white underlayment) from the base-end of the logic board is the best method as it does not put stress on the foil itself.

iPhone 4: Screw Diagram with Grounds?

Wed, 28 Mar 2012 20:14:47 -0700

In my brief foray into iPhone repair, I've come to realize how important making sure I replace every single little screw on my iPhone 4. Is there a diagram that exists or can someone create one, showing all the screws that ground certain components (such as the long screw at the top being necessary for wifi/GPS)?

That would help immensely as some money could be saved on parts when I know there is just a screw that needs to be in place in order for some components to function properly. I think this may be the case with my non-functional mic and crappy sounding speaker.

Thanks!

iPhone 4S: ID this bracket/clip please

Wed, 02 Jan 2013 17:07:53 -0700

I have an extra bracket (pictured below) lying about from an iPhone 4S I took apart some weeks ago and I've looked through guides and cannot work out where it belongs. It has foam padding on the underside.

iPhone 4S: Where does this one-prong grounding clip go?

Thu, 27 Dec 2012 21:42:30 -0700

I am reassembling my iPhone 4S and have a small one-prong grounding clip that fell out after I removed the logic board and before I could see where it came from. It is NOT the camera grounding clip, I have that and know where it goes. It is a black rectangle 5mm x 3mm with a screw hole offset towards one side. A small 2.5mm ground prong sticks off perpendicularly from the opposite corner from the hole. any help on its location and orientation would be a huge help. I would post a photo but I can't seem to figure out how.

iPhone 4s 16GB Black ATT: During LCD repair this fell out... affect mic quality?

Mon, 20 May 2013 19:11:39 -0700

While I was replacing my LCD/digitizer/glass assembly this showed up on my work bench...

Picture:

(it looks gold because of my light source, but it is silver)

It looks like some kind of grounding mesh (similar to what I have seen in the old 4th gen ipod that had the metal back).

My voice quality seems to have suffered (others not hearing me well) after my repair and I'm wondering if this has anything to do with it. I sound fine while on speakerphone and while using a headset w/mic.

I have searched for this everywhere but have found nothing on it. I hope someone knows what this is and that this is the cause of my microphone problem

Thanks.
