It is great to read something good from my former colleagues. Ron was great to talk to and Mark gave many a clue to a packaging engineer like me who wanted to learn Emag simulations. I also enjoyed working on flip chip on SOS which was quite a challenge in the early 2000's.
I still have fond memories of us engineers trying to blast alignment holes thru Sapphire substrate (for an optical comm driver substrate) so we could mount it for passive alignment with the VCSEL & detectors.
I am pleased to hear Peregrine is doing well!
I also agree that it's hard for me to think of SOS as an emerging technology, but perhaps Peregrine's designs and application for SOS makes it novel? In the mid-80's I designed a 64KB (yes, kilo) memory card that used CMOS/SOS memory modules, each consisting of 2 SOS chips mounted on a DIP substrate with a decoupling cap between them. The application was radiation hardened memory for military computers.
Having watched Peregrine (from a distance) for 15 or 20 years, it is good to see that they are not just surviving, but thriving. Still, it is a bit odd to find SOS as an emerging technology. I remember friends at RCA Labs struggling with it about 40 years ago.
