Surge Capacity To Promote The Transfer Of The Rapid Growth Of China Packaging Industry
Recent years, China has become an international Semiconductor Manufacturers and assembly and test foundry production capacity of hot transfer package, the cheap labor to reduce production costs. So the scale of China's semiconductor packaging industry expanded rapidly.
The growth of China's semiconductor packaging industry by two effects: on the one hand, China Chip Chip-scale manufacturing continues to expand, on the other hand, huge and rapidly growing terminal Electronic Applications. Despite China's semiconductor packaging industry Financial Impact of the crisis, but the global semiconductor market, the importance of packaging has become increasingly prominent.
The early industrial development, China's IC packaging and testing of foreign and joint venture enterprises are mainly concentrated in the package has a relatively mature product in a low pin count. However, with foreign investment and joint ventures will be advanced packaging production lines to China, to package substrate-based products appeared to grow rapidly. Ball Grid Array package Chip Level packaging, wafer level packaging and system-level packaging will become mainstream. Wafer Bumping Assembly has also begun to take shape. Perforated silicon technology has been applied in image Sensor On and has been in volume production. In support of the Government's special funds, local packaging companies are quick progress of technology.
Yangtze River Delta region IC packaging and testing industry is still the most promising areas. However, in order to reduce costs, in recent years a number of IC packaging and testing companies have chosen to create a new factory in central and western regions. Part of the integrated device manufacturers and foundry IC packaging and testing companies will shift production to central and western regions, this trend will continue for several years.
China's semiconductor packaging materials market in 2009 to more than 2.2 billion U.S. dollars, more than 1% increase in 2008. Is expected to reach 3.1 billion by 2011.
Transfer of production capacity will continue to promote the growth of China's packaging industry
2004 to 2011 compound annual growth rate (CAGR) of 20% of the main engine of growth from the substrate, high-end packaging materials still rely mainly on imports. In the lead frame section, added several high-end products for the production line etching, however, leading local enterprises and overseas enterprises in the technology gap remains huge. In recent years, begun to replace copper wire gold wire, copper wire diameter of more than 2mil used and low pin count products. More than 90% (in meters) of copper is applied to discrete devices and power devices (with lead frame as the substrate). Copper substrates used in packaging process has also been in volume production. On the packaging plant, the lower packaging material costs and improve production efficiency is the main effective way to reduce costs, especially for the packaging substrate, lead frame and bonding wire and other material parts, packaging material suppliers will face the future more than 20% price cut pressure.
Packaging equipment market in China in 2008 reached 452 million U.S. dollars. Affected by economic crisis, the Chinese packaging equipment market in 2009 is expected to decline about 34%, to 300 million U.S. dollars. With the rapid growth of packaging equipment market, some of the leading equipment manufacturers in China set up a production line. However, local packaging equipment accounted for less than 15% market share in China and is mainly used in low-end market.
Transfer of production capacity will continue to promote the growth of China's packaging industry

How to to implement an Analog to Digital converter using basic electronics?
I need to implement a dual slope integrating type analog to digital converter using basic electronics. Micro controllers (PIC s) or complete a/d converter chips cannot be used. I need to implement this using op amps, BCD to seven segment decoders, counters, seven segment displays,transistors,timer ICs (NE 555), comparators,multiplexers and other basic electronic components such as resistors and capacitors. Here the integrating part has to be implemented using only the basic electronics(Op amps,capacitors and resistors etc).Can any one help me to find a complete circuit diagram for this and a description about its operation.
Can any one give me a cicuit diagram(Proteus or circuit maker) and a description about its operation?
I simulated one using "circuit maker" sometime ago. Let me give some important hints.
1. Let the charge time be 100mS, and the period be 300mS. So you need a rectangular wave generator that is high for 80mS and low for 220mS. Call this waveform A. This can be obtained from a 555. Consider that input is maximum 2V. Pretend that its integral also will be maximum 2V. So you need an interagtor with time cosntant RC of 100mS. This can be done using a 1 meg and a 100nF as feedback C in an inverting integrator. Pretend that the "input" is inverted by gain of 2 inverter. then the input to integrator will be 0 to -2V, for an "INPUT" of 0 to 1V. If 1V is "input", inverter output is -2V, and if integrated over 100mS, output of inverting integrator will just reach a max value of 2V, if at start of 100ms, integrator is reset. One can use an opto for resetting the integrator, driving the LED of the opto from output of 555. The transistor in the optocoupler can be connected across the integrating capacitor.
2. The input to the integrator has to be switched from "input" to "reference" after the 100mS. One can use two 1 megs, with a 10k in series with each, and the junctions connected to gnd through a transistor. If the transistor is ON, that input will be effectively cut off. The transistor T1 for the input will have to be OFF for 100mS ,the integrating period, and the transistor T2 connected to reference through a 10k shall be On during this time.
So during 0 to 100mS, T1 is OFF and T2 is ON. Thus input *2 gets integrated, and integrator output rises from 0 to 2V. After 100mS, T2 is OFf and T1 is ON. Then output deintegrates if reference voltage is say 2V.(See later statements..) It will deintegrate to zero in 100mS starting from 100 mS extending to 200mS. You need to use a 100mS monostable triggered on negative edge of 555 output, for the first 100mS . After this, the monostable output goes low, and its Qbar which is high for 200mS can be used to turn ON T1, and turn OFF T2.
3. The rest is easy. Compare the output of this integrator (using LM139) with a dc of say 20mV (which can be reduced later to 5mV or even lesser.. after the whole thing starts working..) The output of the comparator will be high for the first 100mS as well as till integrator output deintegrates to less than 0 (or 20mV). During this period if you gate a clock of say 5kHz to a 3 digit counter, for the first 100mS, it will count out 1000, and the deintegrate period will be indicated by the balance counts. If "input" is 0.5V, deintegrate period will be about 50mS, and counter will have a count of 1500 at end of 150mS = integrate period of 100mS + deintegrate period of 50 mS. Since it is a 3 digit counter, the "1" will overflow, and display will show 500.
Do these separately by simulation (of individual sections) to see the waveforms and the like..Also read all about this type of converters from data sheet of 7107.
If you do not get a reference of 2V, use a higher voltage zener such as 4.7V, and divide it using resistor networks of 2.7k and 2k to get 2V. Reduce resistor of 10k to 8.2k or so due to thevenin resistance of this divider..
Once you get the whole thing going make measurements at .2, .4, 0.6, 0.8 and 0.9. tabulate the values. You will get to know what is offset if any, and whether the slope is as expected 1V= 1000 counts. If not you can reduce or increase either one of the 1 meg ohms.
