WebChip attach is the bottleneck operation in semiconductor assembly. Chip attach scheduling is in nature unrelated parallel machine scheduling considering practical issues, for example, machine-job qualification, sequence-dependant setup times, initial machine status, and engineering time. The major scheduling objective is to minimize the total weighted … WebJun 17, 2015 · On glass with high pressure (don't break your glass!) it will spread more than on a chip with a rough surface in comparison, but not by 50%. Now find the drop that will cover about 80% of your heatsink. Once you have found the drop-size you need (and over time you will get better and better at it in one go if you need to do it often): florian thost
