MARCH MegaVIA Plasma Treatment System for PCBs

With overall dimensions of 1652x1782x2326mm, the new MegaVIA system offers increased panel loading by more than 54% with only a two percent increase in footprint when compared to a MARCH MaxVIA-Plus. The new platform delivers high process reproducibility and plasma treatment uniformity for PCB panels.

“Nordson has set the global standard for plasma treatment in the PCB market for more than 35 years with its industry-leading MARCH VIA platform,” explained Al Bousetta, director of marketing, MARCH Products. “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. As with other VIA series products, the system provides uniform plasma treatment results to meet rigorous PCB manufacturing requirements.”

The MegaVIA 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 intuitive 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 MegaVIA system’s power-power electrode configuration, balanced vacuum and gas flow, and temperature management technologies.
