Binding chip identification and copy board [chip identification]
Update date：2012-6-27
Do not know if you have the mouse apart to look inside the circuit board, are there any open general toys seen the circuit board, if you open, you will find inside a black thing attached to the above, you know what that is? That is bound to the chip.
When bound to chip it? Soft chip package (to help set the English translation of the bonding and chip coating technology) and plastic chips compared to die to help set the biggest advantage is a significant reduction in chip cost 30% -50%; and simplify the circuit board and chip technology ; has a good waterproof, moisture, oxidation, anti-static, anti-physical wear and tear, slightly acidic corrosion prevention characteristics; earthquakes, cut, anti-T-peel aspect is particularly prominent; absolute confidentiality requirements, many manufacturers choice.
We start by defining bind a chip package, why choose to bind the chip? Because of its low cost, you have no binding chip and single-panel basically with low cost products, while the binding chip for reverse, the people who want to crack a nightmare. Why do I say? Bound chip is very hard to deal with, often the most copied board companies see the binding chip directly to dare to take, because the binding chip material is difficult to handle, and this step is necessary need to be addressed, there is no step not to mention the back of the copy board and decryption, but Shenzhen East conduction technology is a bold challenge to the difficulties companies, engineers before ever thought of using physical methods to deal with the above vinyl, such as machine polishing, manual polishing, but often not good, easy wafer knocked off, or the board broke, causing the PCB copy board can not be.
We chose to use a chemical treatment, tried, tested with nitric acid, sulfuric acid is not good results, and ultimately the East conduction technology to find the production of the manufacturer of the lysate, and where engineers to explore together, study together, to find a dissolution fluid, specifically for dealing with this vinyl, and the effect is particularly good, no corrosive effect on the board, not only can make the lines more clear, and did not destroy PCB, the PCB is a one-time copy board, at the same time very easy to identify the model and manufacturer of the chip is bound to help the customers to produce lower cost.
