I'm not really an expert in this topics but I thought - for 7,6µ bump pitch you'd need something like <1µ placement accuracy and (maybe even more difficult...) also a really high theta accuracy so that all bumps hit their corresponding pad... and then? what can be used to create a reliable interconnect for all of the 4mio bumps? some kind of a TCB kind of soldering process? or is the stack maybe created in a "ziptronix"-type of wafer to wafer bonding?<br />however they achieve it - it seems to be an impressive piece of technology...<br />- ThomasAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-64809182857506110912015-04-30T12:09:02.198+03:002015-04-30T12:09:02.198+03:00Does anyone know how 7.6um micro-bumping is made p...Does anyone know how 7.6um micro-bumping is made possible? micro-bumping at 10-12um I have seen working nicely, but putting 4million bumps at 7.6um is a bit non-yielding from my viewpoint.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-43077458823750414152015-04-30T11:17:56.505+03:002015-04-30T11:17:56.505+03:00Interesting point.
