Replacement Ipod Touch Flex Cable Is it solderless hot bar with conductive adhesive?

Reply by alexmyron

I wish to install a replacement T646 flex cable on my iPod Touch 2nd gen. that is sold online but do not know how to go about attaching the end of it on to the circuitboard.It is sold also on eBay here..

http://cgi.ebay.com/ws/eBayISAPI.dll?Vie...

It seems to be attached solderlessly against the mainboard maybe using a hot bar and some conductive adhesive of some sort?

I have done many repairs, but this one I don't know about.

Does anyone have any info or ideas at all how to attach these tiny multi conductors?

It is a cheap replacement part that includes the WiFi that is broken on mine. I have searched the net and contacted all the sellers, but so far to no avail.

Thanks In Advance!

Appreciate it. I seen that they had a bunch of different ones, wasn't sure which one I needed for sure. Thanks again!

So now...

I'm still trying to purchase this 3M or any similar product of this anisthropic conductive tape, but they will only sell large rolls of it at large prices. I also tried to get a sample without results. It is used to fix many flex conductors and it's also good for LCD repair.

I just want a tiny amount and not many meters that costs many hundreds of dollars. There must be some individual or a company out there that will cut and sell just pieces of it?

Anyone have any idea? You would think there has to be a lot of people either using or who could use this product without buying large bulk amounts meant for large industry.

Anyone?

I'd also be interested in buying smaller(smaller than what can be commercially bought anyways) chunks of this tape. If you could email me at codyormoe@hotmail.com that would be awesome. I have 1 iPod and a few other odds and ends laying around that could benifit from this stuff.

I have searched ebay for this stuff and haven't found it. If anyone sees any for not too much money, I'd appreciate it if you'd let me know.

Thanks!

Hey rick, I have a roll but have not sold any. I've been trying it out and have probably installed it on about 20 iPods so far. I have not had reliable experience with it mainly because the pitch of the connectors on the touch is way too close for this material. Either contact is lost or shorting happens between adjacent pads. I've pretty much ditched the idea of using the tape and have come up with a much better solution. On the last four iPods, I've first removed all residue from the contacts and cleaned lightly with scotchbrite. Then, with alcohol on a q-tip. I then install a small piece on adhesive tape just off the contact pad to hold the flex cable aligned properly. Next, I place a piece of foam directly on the flex over the contacts and secure the battery/LCD frame. Everything is held in place and the foam provides the necessary pressure to maintain good contact from the flex to the logic board contacts. I use command strips foam...I guess it's the right firmness. After extensive testing, this seems to be a very reliable fix.

if you search "3M 970312 Conductive Adhesive iTouch Wifi Ribbon Cable" in ebay you will find what you need. the ebay seller id selling it is wztahotshot08 he is selling it in 1ft quantities for much cheaper then a whole roll

I'm not so sure of the tape's success rate either now as I've had several losing their Wifi and/or touch after working a few weeks.

I followed the 3M directions and cleaned the conductors perfectly and used brand new WiFi flex units with some.

So over time 50% of my repairs are still working after a few weeks and it could go lower.

How do others rate their 3M 9703 tape fix?

Anyone have pictures of this procedure?

I don't have a great imagination and can't picture how you are connecting this.

heres a video on how to repair using this tape

The video is not bad but the bottom line is the 3M 9703 tape is not designed for conductors that close to each other and what eventually happens is unreliable operation because the tape causes adjacent pads to short to each other. There is a proper 3M tape but requires hot bar soldering equipment. I've repaired many of these without conductive tape per my instructions on 8/2/10.

I have had a lot of people purchase this tape and have yet to have even one person complain and say that anything bad happens, I have had more people thanking me about having the adhesive available and how it works and does last(not the other way around). The stuff defiantly does the job, you just have to apply it correctly! the only negative feedback i have seen is in these forums.
