Re: [M100] New zebra strips for M100
Since we don't know the uncompressed height of an OEM strip, we may have to rely on the vendor's recommendation based on compressed height and their materials / process. The clamping tabs on the metal frame do not allow for a great deal of compression distance, so the tolerance of the strips may have to be rather tight. On a M100, with a working LCD, that I have apart right now, I measure the compressed height of 3.02 to 3.09mm at the accessible corners of the glass. You should relay this measurement to your vendor to get their recommendation for uncompressed height.

Re: [M100] New zebra strips for M100
Peter, Thanks for taking the time to take a measurement of your display. You are right. The clamping tabs don’t allow a great deal of adjustment (or clamping force — more on this). The manufacturer recommends 10% compression, with 5% compression minimum. This compression percentage has to take into account a +/- 0.127mm manufacturing tolerance for the zebra strip, as well as any tolerance stackup from the bezel and glass. Unless someone has manufacturing drawings for the glass and bezel (could we be so lucky?) The best we can do is measure a number of displays and see where they fall. My display measured 3.3mm glass-to-board (measurements of individual parts disassembled, assembled dimension by averaging and subtraction). After conversation with the manufacturer's technical guy, he suggested the 3.74mm dimension used for the first prototypes based on his experience and our application. These first tests suggest we might need to be closer to a 5% squeeze, especially in light of the measurements you took of your display. I’m optimistic we can find a dimension that hits the sweet spot for all or nearly all of displays in existence. It will just some displays and some work. I won’t place a full order until its pretty clear we’re on the right track. Thanks again for taking the time to take the measurements. Out of curiosity, how did you take your measurement? Is anyone else wiling to take the same measurement? —Jamie On Jul 15, 2021, 8:00 PM -0400, Peter Noeth , wrote: > Since we don't know the uncompressed height of an OEM strip, we may have to > rely on the vendor's recommendation based on compressed height and their > materials / process.

Peter, Also, I’ll re-run my measurement to see if I was just not paying attention or something. I have a surface plate and most of the metrology goodies available.

Re: [M100] New zebra strips for M100
I measured at the four corners of the metal frame, where the LCD glass / Zebra Strip / PCB connection can be seen and accessed, with a dial caliper. The measurements varied between 3.02 to 3.09mm at these points. The mid points of the length of the Zebra Strip could not be accessed, but should be similar in range to the corner measurements as the glass is flat. One must also consider the effects of uneven thermal expansion of the display assembly, to ensure that there is enough pressure exerted by the Zebra Strip to the PCB and LCD glass. I would also think that an "assembly jig" would need to be created, to keep the PCB and metal frame aligned during the twisting of the metal frame tabs. On smaller displays I had worked on, we had such a jig that allowed viewing the LCD powered on, while setting the tabs, so as to ensure the Zebra Strip was making good connection along its entire length and there were no "dead areas" on the display. It was more helpful this way as opposed to setting the tabs, then testing the assembly and adjusting for any bad spots on the display. The tabs usually didn't take to being bent more than two or three times.

Steve, Thanks for sharing your experience. Depends on the display, I guess?

Re: [M100] New zebra strips for M100 display— any interest?
On one the M100s I repaired earlier this year, it was not so much the zebra strips, but that they seemed to have shrunk. I had to apply thick tape inside of the metal LCD frame to increase the pressure on the strip. I think new zebra strips of the correct height would save quite a few M100s. I am interested in buying 4 of them. I do not think it will help with missing horizontal lines. I am pretty sure that would be broken traces or lifted pins on an IC. I only have experience with the one that I repaired, so take that with a grain of salt. Scott M.

Re: [M100] New zebra strips for M100 display — any interest?
That is quite the initiative. I’m not sure how many LCD problems are related to zebra strips. Of the ones I have had with problem with or helped diagnose a. Corroded contact pad and bad LCD glass, one row was bad, you can turn glass 180 to verify. b. Bad driver chip Not a big sample size. No doubt some others are zebra strip related. I have only heard a few rumblings about zebra strips on the various forums and such too. If I were to try swapping an M100 LCD glass into a T102 for example I might go ahead and install new zebra strips to be safe, so I don’t have to pull it back apart multiple times to mess with the original one. It might take 3-5 years to find enough folks who need to be zebra strips for M100s to go through 1,000 which is something to consider when you are tying up your money upfront to purchase them. I have commissioned a few reproduction parts for old computers now and just want to pass along what I have learned.

Re: [M100] New zebra strips for M100 display — any interest?
I would absolutely buy a small stock of new zebras for the M100! I've been contemplating such a project myself for years. Over the last 30 years, the zebras have deformed to where they seem to take permanent deformation from the copper tracks on the PCB and I've never been able to get them back together again after cleaning. Having new parts available would be terrific. Let me see how many problematic LCDs I have in my "parts machines" right now and I'll get back to you. -Josh > From: M100 On Behalf Of Jamie Nichol > Sent: Tuesday, July 6, 2021 6:34 PM > To: m...@bitchin100.com > Subject: [M100] New zebra strips for M100 display — any interest? > > > Hey All, > > I do consumer product R&D as my day job.

Re: [M100] New zebra strips for M100 display ? any interest?
My experience with zebra strips, in general are threefold: 1. The silicon can "outgas" its oils over time, if they were not baked correctly at manufacture. This oil can contaminate the carbon layers on the "face ends" where the strip contacts the glass / PCB, causing open connections. 2. The face ends of the carbon layers are not always friendly to cleaning. The conductivity of the carbon layers can be lost, especially after 5 years. 3. The silicon can lose its elasticity, causing open connections. This mostly manifests itself during reassembly of an LCD display module if reusing the original zebra strips. Especially after 40 years of questionable storage conditions. When disassembly of an LCD display module was necessary, new zebra strips were always used during reassembly. This just removes a lot of potential problems, especially if you warrant your work. So having a source for replacement zebra strips for the notebook computers would be handy, but at a minimum production quantity of 1000, you would probably still have 800 when you die. Maybe not economical, from a business investment, but maybe from a passion standpoint. I would buy a dozen :-) Regards, Peter -- > > Message: 3 > Date: Tue, 6 Jul 2021 19:33:53 -0400 > From: Jamie Nichol > To: m...@bitchin100.com > Subject: [M100] New zebra strips for M100 display > =?utf-8?Q?=E2=80=94_?=any interest? > Message-ID: > Content-Type: text/plain; charset="utf-8" > > Hey All, > > I do consumer product R&D as my day job.??I?ve admired the M100 as a > brilliant product for the past decade or so, and just picked up a really > sad example that I?m trying to resuscitate. > > A couple of weeks ago I had a some fine-pitch prototype zebra strips made > up to fit the M100 LCD (see pic).??The first prototypes are about 0.3mm too > tall.??I?ll likely have another set of prototypes run with an adjusted > height. > > I have two questions: > > Is there enough interest here on the list to justify an order of 1000 > pieces or so???(Likely price is a few dollars each strip ? more to come on > price.) > > Do any of you have dead LCDs that you would be wiling to sacrifice to the > testing gods???I would like to see ten or so LCDs improved by an upgrade to > the new strips before placing a bigger order. > > ?Jamie > > > -- next part -- > An HTML attachment was scrubbed... > URL: < > http://lists.bitchin100.com/private.cgi/m100-bitchin100.com/attachments/20210706/ba6c5a49/attachment-0001.html > > > -- next part -- > A non-text attachment was scrubbed... > Name: Zebra_Strip_Prototypes.jpg > Type: image/jpeg > Size: 218023 bytes > Desc: not available > URL: < > http://lists.bitchin100.com/private.cgi/m100-bitchin100.com/attachments/20210706/ba6c5a49/attachment-0001.jpg > > > >

Re: [M100] New zebra strips for M100 display ? any interest?
Good point about silicone ‘bleeding’ oil. This indeed cause problems with many conductive rubber things like key contacts, keypads, etc. External contamination can have the same effect. These can be rejuvenated by soaking in a mild alkaline solution such as household ammonia or sodium hydroxide (about 1 teaspoon per liter of water). Depending on the level of contamination it could take 6-48 hours of soaking. I typically rinse well and then soak in 98% denatured alcohol to dry it out. This works very well on key contacts, and keypads but I have not tried it on zebra strips. There is no fix for the loss of elasticity though.

But I also don't need to take them from anyone else from a limited run, so, 2 pairs? Likewise - happy to adjust my quantity on demand for the same reasons. Cheers, --dt

Hey guys, Quick update. I have four displays on hand (thanks Josh!). Measurements suggest a zebra strip height between 3.3mm and 3.4 mm will work best. I’ve been in a protracted conversation with the supplier about best practices for assembly. I’ll have another set of prototypes made at the updated height, rebuild the four displays I have on hand, and let you all know how that goes.

Jamie, Just wanted to check and see if you were successful in getting some new zebra strips made.

Hey All, I do consumer product R&D as my day job. I’ve admired the M100 as a brilliant product for the past decade or so, and just picked up a really sad example that I’m trying to resuscitate. A couple of weeks ago I had a some fine-pitch prototype zebra strips made up to fit the M100 LCD (see pic). The first prototypes are about 0.3mm too tall. I’ll likely have another set of prototypes run with an adjusted height. I have two questions: Is there enough interest here on the list to justify an order of 1000 pieces or so?
