I'm working with an overseas vendor.
We've tested the electronics and code of the product. We gave them the green light to start chip masking. However, a few days later we realized that the working samples of the toys had dB levels (for sound effects only) are too loud for a toy.
The vendor said that we can still change the program.
My understanding is that once chip masking starts we can't change the program anymore.
Can someone explain to me the detailed steps of the Chip Masking process and what can still change during that process?
