Choosing the Best Metallization for your NanoBond® Application
Since the NanoBond® process is almost instantaneous, fluxes are not used. (They just don’t have enough time to heat up to their activation t...
Weibull Analysis of Solder Joint Failure Data II
Derivation of the Weibull Graph Folks, Last time we introduced Weibull analysis. Let’s now derive the relationships needed to calculate the slop...
First Visible Light LED Turns 50!
It is hard to believe, but 50 years ago, on October 9th, the first visible light LED was demonstrated by Nick Holonyak, Jr. of GE Advanced......
Preparing Surfaces for a NanoBond®
The first time I was taught how to solder (as a child), I was told: “All the surfaces need to be mechanically cleaned and chemically cleaned.&rd...
Design Considerations for the NanoBond® Process
The first step of the NanoBond® process should usually happen long before the NanoFoil® arrives at your facility. DFM (design for manufacturin...
Ball-Attach Flux WS-446-NRD for Poor Quality OSP-wetting
While on a recent trip to Malaysia, I interviewed two colleagues regarding trends in semiconductor assembly. My previously-published interview with Sz...
Adding Solder to a NanoBond® Assembly
One of the biggest misconceptions about NanoFoil® is that it is a form of solder. While it may contain a solder coating if specified (usually tin)...
Ultrasonic Testing a NanoBond® Solder Bond
Ultrasonic Testing (UT), performed by acoustic microscopy, is a great way to determine the quality of a solder bond without destroying the assembly. ...
The NanoBond® Process
To successfully use NanoFoil®, you do not need to fully understand what it is or how it is made, although that does help. It also makes for a...
Solder Paste/Preform Bond Line Thickness
When helping customers with the optimization of their soldering process, the question often comes up; “What will my solder bond line thickn...
A Look Inside the Solder Flux Pen
Here is a picture of an Indium Corporation solder flux pen, sectioned to show you the internals. Who DOESN’T want to see THAT, right?!? Fl...
