Even if the customer is far away from cell phone jammer

Even if the customer is far away from  cell phone jammer .
The disadvantage is that the antenna shrapnel stretched height of not more than 4mm above the center of the antenna, otherwise the installation will because antenna shrapnel deformation is too large while the plastic deformation can not guarantee the rebound height, thus affecting the contact of the contact (usually guarantee more than 1mm preload). Antenna stretched out the contact column. Welded on the motherboard antenna shrapnel, shrapnel of the antenna and the antenna contact column contact. Advantages: the distance of the antenna to the motherboard is easy to control; Disadvantages: antenna shrapnel is soldered to the motherboard, may cause the motherboard scrap to make the motherboard in the process of production and use of antenna contacts peeling. (Cylindrical antennas). Note that the working height of the antenna shrapnel. Relax conditions guarantee than 1mm Precompression distance. Some customers might need this function of  cell phone jammer  much.PC keycap thickness 0.7 to 0.9mm. The thinnest 0.5mm and 0.5mm are not mass production, the specific manufacturers to talk about. Note that the horizontal not all of the numeric keypad is disconnected, the leftmost and rightmost button if the connecting rod key. Prevent the keys from the overall prolapse. For example, 1,3 with keys; 4,6 with keys; 7,9 *, # with keys. Numeric keypad and function of the arrow keys to separate the middle to the shell on the left ribs, to prevent the keys from the overall prolapse. 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. Steel thickness of 0.2mm, have a location column. Keycap thinnest 0.80 (or with the manufacturer to talk about can do more than thin). The detailed plan of the site management of  cell phone jammer  should be prepared for the workshop.
Steel and the key space of Plastic in the Z direction as far as possible 0.4mm. Including plastic buttons and Rubber thick 0.1mm. 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. The narrowest width of the area in the steel 1mM. In order to ensure flatness and service life. (Recommended by the manufacturer for more than 1mm, 0.5mm above can do it). The gap between the keys and key minimum 0.2MM. Steel four weeks in the XY direction and inside the enclosure vertical spacing of> 0.3mm. Steel the middle of the gap between the key hole and the hole Rubber 0.2mm. It is especially for the ones who take charge of cell phone jammer .
The keys of the piano plate to design the ground, the shrapnel must be designed to the original and compressed the latter two state.
