17 May 2010

I continued my exhilarating odyssey into the world of calculation. Today, I finished calculating the theoretical distance between capillary and the die under ideal die placement as well as under worst case scenario. By ideal die placement, the die is perfectly situated at the centre of the major flag. On the other hand, worst case scenario infers that the die is displaced 20um.

Next, I calculated the distance between die edge and wire, stretching from the line of ball bond on the die. Again, two situations are considered, that are ideal die placement as well as worst case scenario.

I finished off the day by evaluating the displacement area of wedge bond on minor lead. I took the center placement of the wedge, which is the ideal case as a reference point. Subsequently, I modeled each displacement as a circle centered about that reference point.

All calculations will be shown.

I spent the day tabulating and simulating those data I had obtained from the assembly line into Minitab. This is a software that can depict many parameters akin to any process under inspection. With the helpful Miss June beside me, I was able to simulate, understand and encapsulate the graphs as well as information generated. To put it compendiously, the processes that I had been involved in are stable.

Besides Minitab, I also calculated the maximum distance that the die can deviate vertically before hitting the capillary. Again, all calculations will be shown.

I had basically finish all the data acquisition as well as theoretical calculations relevant to my project. I was asked to detect errors in the method used by Miss June in calculating those similar parameters that I had calculated. After some meticulous inspection, I was able to detect some errors and remedied them. I spent the rest of the day gaining knowledge on how to conjure up a report regarding my project. I was given several reading materials to attain adequate information deemed relevant to producing an engineering technical report.

My agenda today was indubitably to produce a quality report. I gained several skills dealing with graphics in Microsoft Word in my quest to engender a splendid report.
