cell phone jammer can be used for the international purpose

By the specialized Pprt Reliability Laboratory to micro 0.5m drop test to be done 300 times / surface (the cell phone has six faces), 2m drop test each side to do first, real people thrown into the cell phone desktop, cell phone battery, is also subject to at least 4m height alone toward the ground impact fall 100 times and can not rupture. The cell phone is in the adaptability of the test cell phones in different temperature environments, the low temperature is usually in the minus 20 degrees Celsius, high temperature is 80 degrees Celsius. Dripping test using a special cabinet to do the simulation sweating (water into the salt must be better than columns), and takes about 30 hours. It is recommended that customer should test the shielding distance of cell phone jammer.
H4 hardness of the pencil to draw 100 squares on a cell phone case to see whether the cell phone's shell will fall off the paint, some more demanding cell phones, in the shell of the cell phone and then smearing the lie that some brand-name cosmetics, to see whether cell phone paint a different chemical composition odor or Diaoqi of possible. Clamshell flip cell phone 100 000 to check the cell phone casing wear and tear, with a flip of the simulation machine, it can be set to flip the intensity and angle. Jig caught two, a left twist, a right twist, the main strength of the test of cell phone housing and cell phones face large-scale devices. cell phone jammer can be used for the international purpose.
Electrostatic discharge gun all metal contact points for cell phones hit test time is about 300ms-2s or so, and within a humidity-controlled room, while the charger will have the same test. With the power of machines to set the keyboard to hit 100 000 times, if each key of the user 100 is 1000 days, equivalent to using the cell phone about three years time. The cell phone into specific boxes, small sand hairdryer preach up, after about three hours, open the cell phone to see whether the cell phone's internal sand to enter, if there is not good enough, then the cell phone closed, its structural design to be re-adjusted. Checking signal strength of the cell phone is not enough for checking working status of cell phone jammer.
The cell phone casing materials for general use PC / ABS alloy forming join masterbatch. If you have a metallic finish, I do not spray paint is not enough; some black casing color off. Model-GE C1100 C1200 (flame retardant) C1110 (flame retardant) 2850 2950 (high flow) GE expensive (~ 28000/MT), the color is more expensive. The vast majority of cell phone housing (80 ~ 90%) GE's C1110, C1200, C1200HF do cell phone case, can paint, you can also plating, as well as special effects, make a direct effect of paint and metal. Do pay attention to compatibility agent selected, high temperature paint to warp. When testing whether a point is in the shielding range of mobile phone jammer, hand-hold the cell phone and keep it in the position for more than half a minute.
Bayer T specification (non-flame-retardant PC / ABS) is commonly used in cell phone casing. (Nokia, the Motorola, Philips, Siemens, Ericsson (Sony) ....) have with the T series. The T-45: electroplating. Painting (Alcatel, Sony-Ericsson) T-65: painting (Sony-Ericsson, Nokia) T-85: high strength (Siemens, Motorola) notified to the structural design of the cell phone products in cell phone design is the key product features, which requires not only in harmony with the appearance of the product, but also to consider the various aspects of the order of production assembly, painting, printing, mold design and manufacturing. The shape and structure design of cell phone products involves knowledge of a wide range of materials selection; 2. Surface treatment; processing means; packaging and decoration; the use of these factors directly affect the life of cell phone products and appearance of the image changes. The static testing of cell phone jammers should be completed in every point.
