By ripping out, I don't mean use pliers to pull them out of the IC, I mean bend the metal legs (or teeth if you want to call them that) of the IC and keep bending them until they snap off. It looks like you will get a clean cut. to help. A wire can be soldered to the remaing visible cut portion of the pin in the the epoxy package, another point, I dont think this is a wise method, applying force to the pin might actually stress the wire(gold) bonds to the silicon pads this may effect the quality and reliability of the product. The circuit has been changed around a little however the pinout is EXACTLY the same, the components are a little different,but basically they are doing the same thing. The 89C2051 has 2K of flash, and it is not difficult to implement the same functions / features as your product, without actually copying your chip. My products are continously "copied", when it first happened around 7 years ago, I was disappointed and depressed, but now I am amused, none of these people could copy the quality or reliability, nor could they copy the engineering. Manufacturing itself is an art/science, I had to learn all these to consistently produce a reliable product. This does not mean that you should not take copying of your products seriously, for this very reason I am now designing my products around the Renesas R8C/Tiny series microcontroller. These have a serial number to be programmed once locked you cant even erase the chip, if you forget the serial number. The chip programming protocols are proprietary Renesas does not reveal this, you will to buy the programmer only from Renesas. All this should make the copying/breaking very very difficult if not impossible. John. |
