cell phone jammer should complete the inspection more sensitively

cell phone jammer  should complete the inspection more sensitively.
Structure of the internal re-evaluation --- structure of the Ministry of the person in charge of re-evaluation organization departments to focus and do the assessment records, track, modify the results; of Final Appeal of the structural design --- on important issues, the project center is responsible for the final assessment and review of the above assessment conclusions and records; antenna review --- the point inspection of the antenna assessment, combined with the assessment report and the assessment of the vendor to modify, make sure to satisfy the requirements of the manufacturer of the antenna design; structure of the external review --- reference <cell phone the whole structure design checklist ( B. An inter-departmental joint assessment)>, the organization of the market, ID, structure, hardware, software, manufacturing, quality, production technology, procurement sector review, good review records and signature confirmation, according to the accreditation process to modify and confirm. It is the safety action taken for  cell phone jammer . 
The shrapnel compression ratio to make up to 70%. If the shrapnel bottom contact on the battery y need to consider in advance to the middle of a good battery may be the top up, after the shell gap. As far as possible on both ends and rely on x to the middle position. Advance consideration of better electrostatic problem, the connector is hidden inside the battery or battery cover to prevent static electricity hit on the battery connector. Battery cover from the battery and the connector of the parting line between the joint surface than 4mm. Vertical battery connector rear plus block reinforcement to prevent the fall and rushed to weld foot torn off, resulting in power-down. Block the clearance of the bar and connector 0.2mm. Block tendons to increase the C 0.3mm, for easy installation. It is within the rated jamming range of cell phone jammer .
Vertical connector should pay attention to shrapnel compression direction, not designed to back pressure, or the actual installation may be loaded up. JACK in the z to the structural design support, can not rely on the solder joint support. The xy direction is fixed by the positioning holes. Assembled shell, JACK interference, resulting in the assembly is not easy to check the assembly sequence. Deck at both ends of whether there is space for plug positioning and buckle; whether the anti-ESD measures; headphone plug, the turning point, the rubber thickness of not less than 0.8mm, or they pull off hidden. And root fillet. Hang the headphone plug of shell ribs, thickness of not less than 1.5mm, it will be very easy to pull off. Shell in the headphones at the opening should be larger than the headphone jack in the radial unilateral 0.3. The testing status of cell phone jammer should be reported. When we see a novel and has a high-performance, bright design mobile phone, whether you have such a curiosity, this mobile phone in the end is how the design and manufactured in every time? So today we try to use a technical objective perspective, a brief description of the relationship between the structure of the mobile phone design department and departments, and finally to show the various tests before the phone to be available by the manufacturer, so that we can better understand the mobile phone.
