Fujifilm Prescale Ultra Low LLLW (3LW) - Surface Pressure Mapping; Pressure Indicating Film; Tactile Sensor - Pressure Range 28-85 PSI; 1 ft. x 10.6 in. Section - Best Practices Guide Included

The "bad" from my personal perspective. Not everyone will agree with me, which is fine. I think there is room for improvement for some customers. I originally bought one piece of the pressure paper to test laptop heat sink pressure layouts and various other tests. It is shipped in a tube, which is the standard method of shipping from what I have been told. When they ship it in the tube it comes in a very tight roll and makes it very difficult to cut. I am only cutting roughly 1x1 pieces. Cutting such small pieces can be difficult because you basically need three hands to hold it down and cut it. After working with the material, I still needed another square foot of the paper. I really didn't want to bother with it if I couldn't get it mailed in a box as a flat sheet. I emailed them to see if they offered special shipping in a box and sadly got nowhere at first. Their response was you just need to cut it one sheet at a time. I personally disagree with that approach because as shown in the pictures above, the material rests with the resin on the one side, which rests against the other paper in order to protect it and keep it from activating. I don't know how much it affects the results, but I know the resin comes off if you touch it, hence why I'd rather cut a piece with both sheets on top of each other. It helps minimize the chances of inaccurate results from user error. And yes, you can use weights to hold it down (Except on the sheet with the resin), but I don't exactly have that option with where I am working. That would definitely help, but not solve the problem. If you tried to use a weight on the sheet with resin no matter what you do you will lose some resin, which will ruin part of the sheet. Also, since I am cutting small pieces it is easier to mess up the paper than just working with large chunks or sheets. When talking to them, I offered to pay another $5-10 for the special shipping. It would save me time and frustration, which would be worth the extra $5-10 plus I would be less likely to accidentally waste some of the paper. At first they refused to work with me, which was very disheartening. I was expecting a more reasonable talk with them. So after talking to them over the phone, we parted ways. (Initial communication was through email which got me nowhere. The second was by phone call, where they called me.) I spent the next couple or few days mulling over if I really wanted to buy another sheet and decided I really didn't have much of a choice if I wanted to thoroughly finish my testing so I put another order in through Amazon. The "good" and "happy ending" So getting to the good news! To my surprise I found a package on my porch, which was a box! I opened it up and saw it in bubble wrap in a sealed plastic bag... and it was perfectly flat! I could not be happier after seeing how it got mailed to me (well maybe if they were a little more reasonable in the beginning and added a special shipping option in the checkout processes ^^). I am surprised they actually sent it that way to me after the phone conversation we had. I have posted pictures of how they sent it and an example of how the first piece got mailed, which is the standard way. I also sent them an email asking them how to send them a check for the $10. I said I would be willing to pay for the added expense of shipping it so I should pay for it. I feel that is only fair, right? Also, note they told me I was the first person to complain about the paper, which is surprising to me. I rarely complain about stuff, but when I do and it gets fixed I must write a review and compliment them on fixing the issue. When a company fixes an issue they deserve credit for it. I still feel strongly that they should offer on their site a separate shipping option to get it mailed in a box. Anyways, to each their own. Additional notes on the product*: I would like to see a little more detailed paper work...granted it comes very detailed but a few questions arise in the use. It has a 1 second/instant impact reading and a 10 second or greater reading. I use it on heat sinks and the total time runs about 20 seconds to tighten 10 seconds to set and 20 seconds to fully remove the heat sink. It very well may be slightly longer than that but you get the picture. If you are trying to slowly apply and remove the heat sink in a balanced manner as discussed lower down+. How long is too long? What if I have an application that takes 1 minute to do...does that give me different readings? It would be nice to know how this exactly works or if it rests for 2 minutes will that cause over readings? +Also, if you use this for heat sinks make sure you tighten it down like you tighten a car tire. If you just crank one side than another you will get false readings. I have posted examples online showing you can get drastic misreadings if you do not tighten it slowly and evenly on all sides#. I assume it has to do with one side causing the heat sink to "see saw" on one side of the chip and then it gives an inaccurate reading. I will update when I finish my testing to double check the misreading. It has happened once or twice and I want to double check. I'll post first one and verification test that the issue occurs when I am done. Just note this may affect your testing results and look at your results with an open mind and from far away (Big picture). See if there is any weird movement or angle or application that might skew the results. Also I just thought of this. What might have happened was with tightening one side first and than the others. It might have been not because of a rocking motion but because of time. If you take 5-10s to tighten one side all the way and do that with all four sides certain sides will sit longer and maybe that time period cause an over reading as discussed above. I do not have the time to test to figure this out but SPI or Fujitsu should already have this well documented. Let's hope they can figure out, which is the cause. So for now just tighten it like a car tire and do it evenly and quickly. I'll still try it one more time but no guarantee I'll figure out the cause. Also I am doing this on laptops hence why tightening takes longer than a desktop. Desktops have more rugged screws and don't run the risk of stripping as easily. *Note many parts of this apply to the product, which is made by Fujitsu. Also, SPI has stated that they are very interested on customer feedback on application and any issues with testing. They have stated over email that they want to update and add more info on product application if new information arises. This is a good sign of a good company and they have been notified of my findings/opinions on application when it comes to heat sinks. Time will tell if they update the packet info. So keep in mind what I have said if it applies to you. **Important notes about product if you have not viewed their site or understand what it is. When I first bought this I did not realize that the pressure reading is just pink. I only looked at Amazon's site before buying. Someone on a forum told me about this product and I never seen a picture of the paper reading. I only saw the Topaq reading, which I thought was the paper...naive I know. Amazon did not have really any pictures or info on it. To get the special readings you see in the pictures on the site you have to mail it in. This costs 90 dollars per piece....not per square foot but per individual piece. If you have 5 or more it is as low as $50 per piece. So if you have 20 1x1 pieces like I do that is $1,000...I find this pricing completely obscene. I am pretty sure all they do is scan it in a regular scanner and a program generates that image....at most takes 2-5 minutes per piece. I would like to know how much it costs to buy that software or if some knock off can get fairly close. 50 bucks a piece is a joke....sorry but in my position I might as well by the software rofl. But I guess if you are in a niche market with no competition you can highway rob people....or just have no business :P They might as well take down that price and do a quote base system at that price. If they would charge me 100-200 bucks to scan 20 1x1 pieces I would probably pay that even though that can't cost them more than 30-60 mins to do :/ They could just scan it in one scan and I would be happy...oh well. I'll update with more information as things come. Also I'll update it if SPI gets back to me about anything. Also check their site for the documentation that comes with the papers. It is very informative and you should read it before buying so you understand everything.
