The assembly description is included in the working instruction of cell phone jammer .
A long-term study of electronic products on the impact of environmental pollution experts, a cell phone battery pollution load of waste, equivalent to 100 ordinary batteries. Used as a traditional cell phone, contain potentially harmful substances to the environment at least 20 species. Researchers have made an experiment, an old cell phone batteries, can contaminate 60,000 liters of water. "60,000 liters of water enough to fill three standard swimming pool." Cell phone batteries on the market today, the main points of nickel-cadmium batteries, nickel metal hydride batteries and lithium-ion battery 3 species. "One of nickel-cadmium batteries contain heavy metals as cadmium, harmful to human body. Have long contaminated, there may be emphysema, bone changes, anemia and other symptoms and may even lead to paralysis." The experts just such an account: reset the cell phone, the average life of 5 years (excluding its been sold several times in fact, not many cell phones can be used for 5 years. the authority of environmental protection organizations in Hong Kong a statistical average life of a cell phone for 600 days), each cell phone only one battery. Hefei urban resident population of 300 million or more (according to the Hefei Economic and Social Statistics Report 2009), calculated according to three million.As the recycling of used batteries can not find the departments and enterprises, recycling of used batteries often encounter "homeless" situation. Such as Jinan Ginza shopping on duty since 1998, recycling of used batteries, so far has recovered hundreds of thousands of festival, in addition to a business as part of the treatment trial, the rest still on the mall. Beijing was established in 1998 the usefulness of garbage recycling center, over the years has collected 400 tons of used batteries, still has most of the stack containers in the recycling center [4]. Recycling of used batteries only to move a home together in one place, but the pollution itself, this method is not desirable. cell phone jammer still can be used in such serious locations as the party and government institutions, theaters and so on which need tranquility.cell phone jammer components mainly include: main machinery, antenna, power supply adapter. Recycling of waste batteries has been difficult to handle, it is because our country has not yet established a comprehensive network and system for efficient recycling, waste battery processing industry has not established a set of industry, large-scale and specialized mode of operation. Although various types of waste processing technology has a lot of batteries, but some of the more mature, but a variety of economic factors constraining the development of battery disposal industry. Low recovery rate for disposal of batteries, long cycle efficiency is difficult to have too many economic benefits, even profitable, but also lose money, it is difficult to attract investors, so it is difficult to form an industrial scale, the scale can not be without realization of benefits.

The circuit below feeds a controlled current and voltage to a 3.6v lithium ion battery. The current is limited to 300ma and the voltage is limited to 4.2 volts. The circuit uses a LTC1734 IC from Linear Technology. No diode is needed between the circuit and a 6 volt solar panel. Some very nice 6 volt solar panels are available from www.plastecs.com Their SP6-200-12 cranks out about 1 watt while the SP6-300-12 can produce about 2 watts. Assuming a 6 hour sunlit day, the 2 watt panel will pump about 1.8 amp-hours into a battery.

The circuit has both square-wave and triangle-wave output. The left section is similar in function to a comparator circuit that uses positive feedback for hysteresis. The inverting input is biased at one-half the Vcc voltage by resistor R4 and R5. The output is fed back to the non-inverting input of the first stage to control the frequency.

Circuit diagram :



The amplitude of the square wave is the output swing of the first stage, which is 8V peak-to-peak. The second stage is basically an op amp integrator.

The resistor R3 is the input element and capacitor C1 is the feedback element.

The ratio R1/R2 sets the amplitude of the triangle wave, as referenced to the square-wave output. For both waveforms, the frequency of oscillation can be determined by the equation: fo= 1/4R3C1 * R2/R1

Here is the product performance of  cell phone jammer .
PIN code (Personal the Identity Number The Personal Identification Number) is a 4-bit to 8-bit personal to enter a password, also known as the PIN1 code, the user only enter this code, your phone to the SIM card to access the data. Belong to the SIM card password to protect the security of the SIM card. The initial PIN code, SIM card, usually set to 1234, the user can change it easy to remember the number. Attention to modify the PIN code must be firmly in mind, and do not remember in the mobile phone. PIN code, the main role is to prevent the SIM card is lost stolen to fight the phenomenon. Start a PIN code security function on the phone every time a user after a reboot. Here is the ambient temperature of  cell phone jammer .
GSM system must be between the phone and automatically identify and determine the legitimacy of the SIM card and mobile phone on the "password", the only system approved in order for the user to provide services. If the user is a continuous three incorrect PIN code, SIM card will be locked, must re-initialized in order to use the telecommunications sector. The PUK (PIN Unlocking the Key, unlock code) is the key to the solution PIN code lock. If you have three consecutive entered the wrong PIN, the phone will self-lock card, then you must enter the correct PUK code to unlock card lock, and then prompted to set a new PIN code. If the PUK code for mismatched 10 times, then the SIM card of the suicide program will start automatically, the card will be scrapped, only changing the card. PUK code is provided by the carriers operating room.
Best 3 to 5 times the manufacturers recommend the initial use of the battery to fully charge and discharge process, in order to eliminate electrode materials passivation, to achieve maximum capacity. Promulgated in 2001, three nickel-metal hydride nickel-cadmium and lithium-ion battery, GB have clear provisions in the detection of its initial capacity, the battery can be five times the deep charge deep-release, once required, the test can be stopped. This is a good explanation of this phenomenon I said so, said the second activation is also possible, the user first used the "new" battery as far as possible several deep discharge cycle. However, according to my tests (for lithium-ion battery), storage of 1 to 3 months lithium-ion battery.  cell phone jammer has the advantage of convenient use.It is towards the heat dissipation of cell phone jammer
It deep charge deep-release cycle of treatment, its capacity to improve the phenomenon is almost non-existent (in the symposium on the battery to activate the test report). Three secondary charge 12 hours. This issue is closely linked to the above battery activation, tentatively set to the factory battery to the user hand electrode passivation phenomena, deep charge deep discharge cycles in order to activate the battery 3 times. In fact, this problem is transformed into a deep charge is not to charge 12 hours. I have another article on the cell phone battery charging time has answered this question the answer is no need to charge 12 hours. the early days of mobile phone nickel-metal hydride battery because of the need to complement and trickle charge process to achieve the most perfect state of full charge , you may need about five hours.  cell phone jammer is the ideal shielding equipment for actively preventing cheating.

 When cell phone jammer switches on and starts working.
The shell mold cavity and core materials to use wear high hardness mirror mold steel. Mold also good material intensity and use standard mold base, another like the top tube mandrel also use the standard, in order to improve the quality and speed of the mold manufacturing. The choice of mold material, specifically to see the Table of the chapter of the book material. Materials, heat treatment of the mold material. Means of heat treatment of the mold material heat treatment of plastic mold materials commonly used in tempering, carburizing, quenching. The heat treatment is conducive to metal machining, to improve the machining accuracy, surface hardness, wear resistance and stability. For example, we can often see a phenomenon: the new mold parts to do good, do 1-2 million. It is convenient to charge cell phone jammer .Faults of cell phone jammer can be solved as soon as possible
Open before and after the shell will damage the lack of any assembly of components can not be missing any parts assembly prototype hooks, and shell assembly, the parts must be complete, experience tells us: that the parts often less fitted, after that part is a problem. And structure of the assembly not only focus on the assembly structure, the same concern with the structure of the PCBA and connector, and a large, high components. A good approach is in strict accordance with the BOM and assembly diagram to do, so easy to find problems. Measurement and assembly of prototype size you want real-time to make a record, otherwise easily forgotten. Specific assembly and test Table 2-5 phone prototype structure assembly Checklist prototype assembly inspection is not only a product quality inspection.
Missed drop is the actual accident situation occurs most frequently use their mobile phones, drop test reliability of the test structure design stiffness and strength test. In the drop test height of 1m, the force is about 10 times its weight chassis, so a good estimate of the structural parts and packaging design stiffness and strength. The drop is more common to test the battery off, so the shell of the card after the battery into the structure of the extrusion force is to be strictly calculated. The structural design of these trials need to understand the methods and principles to guide the design and improvement of the design. The content of these trials the implementation of the responsibility of the professional engineers of the quality management department. The workshop has issued the newest model of cell phone jammer .It is along the thread on the host of cell phone jammer
