This is the first LCD Module to incorporate die chip in Vikay. Lai and I were honored be selected as the Guinea Pigs XD
It sound simple. Just replace the normal chip and replaced with a die chip. Tada.
We wished it was so simple. I will be in charge of designing the PCB and Lai will be in charge of working with the die designer to come out the die chip.
The biggest problem we faced is short circuit in the bonding wire. The position of the pin out on the die and the PCB are different. It can't be the same due to space constraint. It took us a couple of weeks to resolve the problem. it took us 2 more revisions before we went to production. The layout pattern that we designed is used in future design, so it is not a waste effort.
V2002-2 path the way for chip on flexi (flexible PCB), which is another team problem now.
PS All PCB boards in Vikay is manually route by Mechanical Engineers.
Disclaimer - These PCB are not stolen. Prototype boards and dead modules are given to Mechanical Engineer when they left the company because it is hard to convince one to believe Mechanical Engineer can design PCB in the 90's.
