1, memory stick manufacturing equipment:
Tin machine, SMT mounter, wave soldering furnace, AOI equipment, reflow oven, BGA replanting machine and so on.
2, a brief introduction to the memory stick:
Memory stick is a computer component that can be addressed by the CPU through the bus, and read and write operations. Memory sticks used to be an extension of the main memory in the history of personal computers.
With the requirements of computer software and hardware technology constantly updated, memory sticks have become the whole of the read and write memory. What we usually call the size of a computer's memory (RAM) is the total capacity of the memory stick.
Memory is the basic components of the computer (including microcontroller), from the day of computer memory.

Memory Stick Manufacturing Costs:
1. The circuit boards used for the memory sticks are supposed to be 4-layered boards. The price of making a 4-layer board should be 0.12 yuan a square centimeter. Before the circuit board production to have circuit research and development and a lot more.
2, is the procurement of devices, devices are mainly said to be the price of the 16 or 8 chips, each 4 to 5 yuan 7 to 8 is not sure, in addition to the chip other than things are not worth, 1 cent.
3, is the circuit board soldering, each solder joint charge 2 cents. A board is usually a few hundred points, each chip is a few dozen.
4, circuit board: drilling machine 20W, laminating machine 10W, hot air leveling machine 10W, corrosion channel 20W, silk screen printing machine 5W, cutting machine 5W fly, needle detection machine 20W.
5, welding: automatic mounter 20W reflow 40W wave soldering 15W
6, chip production is generally no one to do it, are to buy off-the-shelf or foundry
