Production soldering techniques that persist on the shop floor each have their own unique advantages. For complete board assemblies with standard joints and built-in volume, convection reflow is a perennial choice. For through-hole joints, the solution is wave soldering. A relatively small number of solder joints may justify robotic or human hand soldering, but another soldering technique that seems to be gaining prominence is laser soldering.

There is a single decision at the center of every die-attach conversation right now that isn’t as much about chemistry as it is about control. This is most evident because silver prices have experienced significant volatility, evolving PFAS requirements are increasing regulatory and customer scrutiny, qualification windows are shrinking, and the packages that support AI, automotive, and power infrastructure must meet demanding performance and reliability requirements.

It’s impossible to deny the impact of AI in manufacturing, engineering, and electronics. Every day, we read about new AI platforms, automated design tools, predictive analytics, intelligent inspection systems, and digital assistants capable of generating reports, reviewing documentation, or analyzing vast amounts of data in seconds. The excitement is justified because AI is transforming the way we do business.

An interposer is a thin substrate positioned between a semiconductor device, such as a BGA and PCBA, containing conductive features that allow electrical connections to be rerouted, recreated, or modified between the component and the PCB. Interposers may be manufactured from organic materials such as polyimide or FR-4, as well as silicon, glass, or other specialized materials. In PCB rework, they are most commonly used when the existing board design cannot easily be modified through conventional rework techniques.
