cell phone jammer of high quality will gain more and more customers.
Results found: conductive adhesive no blistering, wrinkling, loss and other bad, as far as the resistance between two points to meet the requirements, and the adhesion of 3N or more qualified. Reference to the corresponding national standard to measure the thickness of the coating at the end of line drawings. Reference to the corresponding national standard to measure the surface hardness of the coating degree line drawings. Reference to the corresponding national standard, select the appropriate method of measuring coating adhesion to meet the requirements. Reference to the corresponding national standard, the hardware components for the neutral salt spray test, in 35 o C ± 2 o C in an enclosed environment, humidity> 85%, PH value in the 6.5-7.2 range, with 5% ± 1% of Nacl solution continuous 48h salt spray, check the metal surface without rust generation. Note: You can use room temperature with 5% ± 1% of Nacl solution soaked in lieu of salt spray test, if the external conditions, salt spray test must be carried out; the case of internal parts, can not be salt spray test. Accordance with the standards of the need for welding metal plating (such as baseband shield) for solderability test: Test method: the pin into the no-clean flux in the 3 to 5 seconds out of drying, and then immersed in a temperature of 235 o C ± 5 o C The solder pot 3 to 6 seconds (63 tin solder should solder composition is 63% tin and 37% lead), remove the natural cooling observed after welding firm, its surface should be distributed evenly and the surface of the solder was bright silver white. cell phone jammer catches more and more attention for the wide use of the cell phone.
Nut with a force gauge test is greater than the maximum damage to pull 7Kgf. Nut with a torque meter test torque is greater than the maximum damage 3.5Kgf.cm. Will be equipped with a flip of the front shell assembly in the life of a dedicated tester on the flip to 40-60 beats / minute speed, flip flip 50,000 times, trial, when the clamshell without cracking damage, the hinge function of the normal when qualified. First with a cotton cloth dipped in ethanol (concentration ≥ 99.9%) of the printing parts degreasing, drying, etc. The 3M600 will be glued to the tape printing area, and use a pencil eraser to wipe the contact area, to enhance the tape and the test area of the contact area let stand 90 ± 30s after; hand grasp the end of the tape, tape ripped off rapidly in the vertical direction, the same position test five times, when the printing is no visibility when passing off. The environmentally-friendly characteristic has become the new goal of cell phone and cell phone jammer industry. cell phone jammer is used in the petrol station for the security of the public. With a cotton cloth dipped in ethanol (concentration ≥ 99.9%), weight 500g wrapped in a dedicated head (wrapped in cotton after the first test area of about 1cm 2), 40 to 60 times / min, 20mm travel around , the sample surface, wipe back and forth in 50 cycles.
