Image sensors adopt wafer-level packaging for mobile phone cameras
… formed from a predominantly tin-based solder, likely a tin-silver-copper combination. The final step is the die separation . Most of these steps are discussed in the Shellcase patent [4], filed in 1995, but at least for us reverse engineers …
