When the customers need to crack mcu,they will supply us the mcu part number and then we can quote them.So the
customers will shipping the working samples to us,and our engineer will test the samples when we collect the samples,
but sometimes we engineer will find the right part number is different with which one the cuctomers told us. Because of
the difference,we engineer will give another new price and maybe they are so much difference.Below are the explanation
from our engineer,please check:
1.The customers have made a wrong part number.For example, the customer's sample part number is AT89C51RC,but
he tell us AT89C51.The price for AT89C51RC and T89C51 are much different.
2.The pin of customer's mcu is blown,so we need to do much more work to repair it.(this work will cost much money,even
the fee is higher than the cracking cost)
3.The part number writen on the sample mcu is not right,after test we can check out the right part number,and we will
feedback to the customers as soon as possible and give the new quotation to customers.If the customers aggree,we will
go on the work,not aggree,we will ship back the sample to customers and refund the deposit to them.
