Cell phone jammer can be used for a longer time

Do not set the mold parting line in the typing, but ran to the shell internal direction along the mounting surface of 0.4mm or so, or the entire run into the parting line, so that after assembly the other shell pressure live to see the flash in less than plating. keypad conductive rubber base convex height of 0.3 diameter φ2.0 (φ5dome),, diameter φ1.7 (φ4dome,), plus glue draft about 10 degrees. Boss DOME gap 0.05mm. If using a PC or hard materials, boss height can be more than 1mm. But try not to use hard contact, a lot of experience have shown that this case size is not easy to control, it is easy to go wrong. Key board in the XY direction on whether the proper positioning, the positioning holes unilateral gap 0.1mm. FAI of  cell phone jammer  should be done as per the company procedure.
The key board is whether the limit in the Z direction, the back support to avoid subsidence of the keyboard. The key board to do the former top pressure, prevent the keys from the lock or subsidence. Note that box of buttons, shell buttons with the draft, draft z direction with the surface parallel to the v-type, can not be made, otherwise the outside gap, while the interior has been interference. Leverage keycap edge of a width> = 0.5MM. Lever key with the shell surface hole unilateral clearance minimum 0.2mm. Keycap edge of leverage in the Z direction with the housing wall clearance can not be 0, otherwise they will be for moving space insufficient with keys. The DOME itself and the key board need to add DOME attached positioning hole diameter of 1mm. The area of cell phone jammer  is important to the quality and performance.
dome sphere must chose to take three or four concave point in order to avoid dust or oil slicks DOME connectivity performance. Button surface should be higher than the surface of the shell mother die at least 0.3mm. Reset-Key below the die face; Reset-Key's press can not be stuck in the shell. If the Reset-Key and Key hole coaxial poor control, consider the Reset-Key and Key Rubber separation. If not specified, shall be added to the black mylar shading film thickness of 0.1mm. The keycap pulling force to achieve 1.5 kg with the manufacturer to confirm this point. Surface treatment process. For which KEY is made of RUBBER material. Appearance can not be shrunk, scratches, weld flash. Therefore, the site management of the area of cell phone jammer is very important.
This product is not standard size, please refer to the PRO / E-drawing. Feed inlet position to negotiate the location of the GATE shall not be higher than the surface where the 0.05 MM. In the standard size for the finished size. KEYPAD the action force of 55 to +10 g, resilience> 20g. KEY surface the number of mold-resistant up to 500K times. Without individual tolerance before 10. Mold according to the icon tolerance class and engineers to review. With the size of the "*" for QC control size. The appearance of electrostatic membrane keys: 50550 Weak plastic protective film, or 62993 electrostatic protective film, without glue. TPU thickness of 0.2 or 0.25mm, bump height of 0.3mm. Bump around can thicken thickened. Edge of the buckle hanging District thickening. The site area of   cell phone jammers should be managed well.
