Is it time to Reinforce In-package Solder Joints Using CNF?
Article published in MEPTEC Report, Volume 18, Issue 1.
One-dimensional carbon nanostructures have been known and fabricated for more than a hundred years and were originally rWe describe a fast and cost-effective process for the growth of carbon nanofibers (CNFs) at a temperature compatible with cThe trend towards smaller interconnects is starting to present assembly and reliability challenges. While desirable by users, smaller diameter copper pillars present an even more significant challenge to assemblers and reliability issues for end-users. However, nanostructures in the form of carbon nano-fibers (CNFs) embedded with solder or conductive epoxy produce stronger component interconnections that enable smaller diameter copper pillars. If desired, the reinforced fiber bumps can be less than 10 μm in diameter and up to 20 μm high. Attachment of the fiber micro bumps uses conventional thermocompression bonding.

What is a carbon nanofiber (CNF)?
Carbon nanofibers is a supermaterial. It is stronger, more elastic, and lighter than steel. It conducts heat and electricity better than metals. And it can be used to thousandfold the surface of materials. Let’s take a closer look at these tiny fellows.
Miniaturized capacitors with carbon nanofibers
Smoltek has developed the world’s thinnest discrete capacitor. You have to stack ten of them on top of each other to reach the same height as today’s industry-standard when it comes to surface-mounted capacitors. The most amazing thing about this microscopic capacitor is its performance. One square millimeter has a capacitance of a whopping 650 nanofarads (650 nF/mm2). Read on for more details.
