Double sided adhesive tape for cell phone repair
In some cases your replacement part may include a pre-cut adhesive made specifically for the phone that you are working with. Other times you may find yourself creating your own. In most cases you will need one of the types shown below. Each may have it's own advantages depending on your project. They vary in strength, thickness, and design so you should consider those properties when choosing which kind to use. You will also want to consider the characteristics of the surfaces that you will be bonding. Do you want very strong adhesion or are you working with something that you may want to remove again in the future? Typically screens should be bonded with something that won't give away easily while a flex cable being attached to a housing should not be so stuck that you will rip it when peeling it away. Whether you are repairing your own phone or a customers why not make future repairs as safe and easy as possible?
Double sided adhesive rolls come in a variety of widths
The advantage of adhesive on a roll is that you will have a consistent width. This can also be a disadvantage as different projects will require different sizes. If you are buying a roll for one time use that only requires one size then it doesn't really matter much. If you perform repairs regularly though it is a good idea to invest in a wide variety of double sided adhesive rolls. The adhesive itself may be thinner than that of the 3M sheets.
Red Tape adhesive- one of the strongest
This roll is very sticky. It is also a bit thicker than the two above. For situations where a certain amount of padding is required such as when working with phones like the HTC MyTouch 4G or Vivid this is perfect. We use this for iPads and are very pleased with it's performance when compared to pre-cut iPad adhesives.
3M300LSE adhesive is easy to cut
If you need several different lengths and widths to be cut for your repair then you can probably create them all using the rolls or sheets shown below. They have a good amount of stickiness but are also easy enough to remove if you apply some heat. They will often become distorted when you remove them and will probably need to be removed and replaced during each assembly/dis-assembly.
