Yousef, Thanks. Steve, The ones with wirebonds are mounted in QFN packages, the ones with solder balls will be mounted face down onto a substrate. When in high quantity production the chips are usually encased in plastic, but some of the high performance processors are mounted in special packages th...

Gem, I got 4 of the clip on Ikea LEDS, and using all 4. I may try another level of diffusion in addition to the stryrofoam cup. The light distribution isn't as uniform as the dual tents, but doesn't require the complex setup either!! The dual tents loose lots of light which is another drawback. Now ...

NikonUser, Those are superb images!! The detail and color are stunning!! I have yet to move past 10X, so this is a real treat to see such quality at these higher magnifications. I noted you use a D610, do you have any issues with it missing a remote trigger now and then? My D800 and D800E both do th...

Here's a crop of a crop to get this to fit within the upload limit. This was taken with the single tent configuration, strobes and a styrofoam cup over the subject. Note the heavy wirebond shadows on the chip edges.

Rik, I could not get Lightroom to compress this image to 300KB, so I cropped it into 3 separate images, but at least I got them to upload!! This is a chip I found in our lab trash that has mangled solder balls that have been severely oxidized. A good chip would have shinny solder balls that look lik...

Gem,

Those are really nice, love the colors. I am trying to use the IKEA LED lamps too. Using a styrofoam cup surrounding the subject as a diffuser. The Lamps are good deal for $15 IMO.

Steve, Thanks, and yes the light blink in the house!! When the strobes fire they all recharge at the same time, which causes the lights to slightly dim! Here's the image I posted on your thread. http://www.photomacrography.net/forum/userpix/3595_Cornell_PPM_1_ULR_1.jpg I can't seem to post other ima...

Rik, I did do some retouching, sorry if was misleading on this. However it was relatively minor, most was touching up the shadows and debris on and around the chip. At the pixel level you can see some bleeding artifacts, but generally it's not bad if I follow the recipe described above. Early on I d...

Rik, Since this is based upon your superb Zerene Stacker, you are asking me :D Seriously though, I surmised that Zerene's algorithms like continuous flow of in focus thin ribbons across the chip surface. With that in mind I try and place the chip image angle such that Zerene has something to "grab" ...

Here's one with the single tent lighting, note the harsh wirebond reflections. I didn't try and edit these out, but did some editing in the previous image.

Thanks Steve. I was doing the stacking & PP on my rMBP until I got a Mac Pro, still takes awhile though. At 500+ images, all from a 36MP D800E at 110MB TIFF, it take some time & disk space!! Hey think I got this image to load up!! http://www.photomacrography.net/forum/userpix/3595_DD2A8Bit4cULR_1.jpg

Chris, Probably something with our work server at my end, don't know. I tried a few times with no luck but will try again soon. The 15 seconds was basically to let everything die down, the heavy lens combo and focus rail on the tripod took forever to damp down. plus the Nikon D800 must flip mirror u...

Nice work. Note the aluminum wirebonds. I would image the plastic packaged logic are really difficult to open. Long ago we used sulfuric acid fog to eat away the plastic to get access to the bare die. Of course this ate away the wirebonds and pads too!!
