Technical requirements of cell phone jammer

This cell phone foil work has been completed, to the excess membrane crop: be careful with the knife along the edge of the cell phone casing, cuts off the excess membrane, and finally do not forget to cut handset transmitter hole. Cell phone film is probably the process is complete, as to be affixed well, and posted quickly to rely on personal hard work and practice, we have to believe that practice makes perfect, and continuing to draw on experience in learning, innovation, constantly updated in order to meet the needs of handsets , the concept of the changing situation. The third part of the materials, purchase. cell phone jammer  only shields the cell phone signal in the specified area.
The cell phone film there are four kinds of material: pp material, pvc material, pet material, arm material. Cell phone film material is different. pp materials of the film is relatively soft, light transmission is also very poor, will not achieve the scratch, anti-wear role, can only be anti-dust, and advice that will be used as a major ineffective, basically consumers abandoned. pvc material film is soft, easy to paste, but it is rather thick, not very good light transmission properties. If you tear off the foil, leaving adhesive residue on the cell phone screen, affecting appearance. pet material of the film, has a high light transmittance. cell phone blocker should be placed in the well vented position.
Torn off and no adhesive residue, and also less prone to foil the middle of the small bubbles. However, the high reflectivity of this film, cause users to not see the words on the screen, but also easy to leave fingerprints and other marks on the surface. arm material, this material membrane surface is the latest Process, with the ability to wear anti-scratch. The same time, the paste of the products of this material there are no air bubbles, the light transmission is also very good, tear off without leaving any traces. The best of this film, relatively speaking, of course, price is the most expensive. Buy cell phone film, to see its materials, but also to understand the durability of the film transmittance and viscosity. Professional cell phone film, the transmittance of the protective film is the most important factors. Other objects on cell phone jammer  and dismantling of the antenna are not allowed when it works to avoid influencing the shielding effect and damage to the machine.
Wear: the cell phone film is used to protect the screen, so the wear resistance must be high. Especially for handwriting input cell phones, film wear resistance is even more important. Generally speaking, the higher durability cell phone smoothness of the film, is also higher. Transmittance: transmittance of poor cell phone film will hurt the eyes, under normal circumstances, the cell phone screen itself, the light intensity has been low, paste a layer of foil will increase eye fatigue. High-quality cell phone film transmittance about 95%, while the poor in less than 80%. Easy Viscosity: quality film can clean the surface of the screen under the premise of self-adhesive and not prone to bubbles. Here is the inspection items and technical requirements of cell phone jammer .
More importantly, high-quality film using multi-static paste, no need to glue, you can repeatedly use and even washing. The film on the back of the general poor quality glue, must not be used repeatedly, not to mention washing. Part IV. Cell phone film addresses selected. Cell phone film is a rapid consumption of the product is completely an afterthought Therefore, if the location is not good, there is no "traveled" ran a dedicated cell phone film downtown The lots are the best choice. This is no need to consider, but the busiest section of the high cost I have to consider, in a simple inspection of the downtown area of the county, I had to give up the idea. The silk-screen of case and whisker of the adapter of cell phone jammer should be clear without wrong letters.
