ITW EAE Granted Patent for Electrovert DwellFlex 4.0 Variable Contact Wave Solder Nozzle
June 14, 2022 | ITW EAEEstimated reading time: Less than a minute
The U.S. Patent and Trademark Office has issued Patent No. 10,780,516 protecting Electrovert’s DwellFlex 4.0 Variable Contact Wave Solder Nozzle. Invented by ITW EAE engineers, John Dautenhahn and Greg Hueste, the DwellFlex 4.0 is the first nozzle that allows the wave width to be adjusted on-the-fly variable board types are run through the wave. This ensures solder contact time is optimized for a high mix of board types without losing production time to change conveyor speeds.
Optimizing the length of time the PCB is in contact with the wave is critical to achieving proper topside hole fill without introducing copper dissolution. DwellFlex 4.0’s software compares the recipes between the products and adjusts the wave contact length, pump speed, blower speeds, and fluxer settings on-the-fly as needed. It takes less than ten seconds to make the adjustment between high mass and low mass boards and ensure superior solder results.
DwellFlex 4.0 is a single wave solution that includes both the turbulent and laminar dynamics of the wave within one continuous solder wave, eliminating the temperature drop that occurs between typical dual-wave configurations This single wave solution improves nozzle efficiency, promotes better topside hole fill, and reduces flux degradation.

Knocking Down the Bone Pile: Gold Mitigation for Class 2 Electronics
05/07/2025 | Nash Bell -- Column: Knocking Down the Bone PileIn electronic assemblies, the integrity of connections between components is paramount for ensuring reliability and performance. Gold embrittlement and dissolution are two critical phenomena that can compromise this integrity. Gold embrittlement occurs when gold diffuses into solder joints or alloys, resulting in mechanical brittleness and an increased susceptibility to cracking. Conversely, gold dissolution involves the melting away of gold into solder or metal matrices, potentially altering the electrical and mechanical properties of the joint.
