Nordson Electronics Solutions has announced the development of a plasma treatment system with a 15-cell configuration for panel sizes up to 30 x 52 inches in printed circuit board manufacturing. With overall dimensions of 1652mm W x 1782mm D x 2326mm H, the new system, known as the March MegaVIA Plasma Treatment System, offers increased panel loading by more than 54% with only a 2% increase in footprint when compared to the company’s March MaxVIA-Plus system. The company says the new platform delivers high process reproducibility and plasma treatment uniformity for PCB panels.
“The new MegaVIA plasma system builds on the success of earlier platforms with increased process capacity for large panels and minimum use of valuable production floor space,” Al Bousetta, director of marketing, March Products, said. “As with other VIA series products, the system provides uniform plasma treatment results to meet rigorous PCB manufacturing requirements.”
The new system provides plasma treatment at 40 kHz and accommodates all common gases – CF4, oxygen, nitrogen, and argon – with high process reproducibility and uniformity. An EPC controller with Windows 10 PC-based touch screen HMI allows for a wide range of data collection and control capabilities.
Plasma treatment uniformity is critical for a large chamber system. Higher than 80% uniformity for desmear and etch back applications to both sides of the PCB panels is achieved using the system’s power-power electrode configuration, balanced vacuum and gas flow, and temperature management technologies.
