The cost to change an IC (Integrated Circuit) can vary depending on several factors, such as the type of IC, the complexity of the circuit, and the cost of labor.
If you are referring to replacing an IC on a circuit board, the cost will depend on the type of IC and the difficulty of replacing it. Some ICs are surface-mounted and require special equipment and skills to replace, while others are through-hole mounted and can be replaced more easily.
If you are referring to the cost of designing and manufacturing a custom IC, the cost can range from a few thousand dollars to millions of dollars, depending on the complexity of the design and the volume of ICs being produced.
It's best to consult with a professional technician or engineer who can assess your specific situation and provide an accurate estimate of the cost to change an IC
