Nordson MARCH Introduces Next-Gen RollVIA Plasma System
Concord, CA — Nordson MARCH has introduced its latest RollVIA plasma system, a self-contained vacuum plas-
carbon removal and descum/desmear for cleaner surfaces, as well as etch- back. Etchback removes a slight amount of dielectric contamination between internal copper planes dur- ing PCB production. Roll-to-roll processing, also
known as web processing, reel-to-reel processing, or R2R, is the process of creating electronic devices on a roll of flexible plastic or metal foil. The Roll - VIA plasma treatment system is self- contained, so that the vacuum system, plasma chamber, control electronics,
and 40 kHz power supply are housed in a single enclosure. The system has a compact 5.8 x
6.7 x 7.7 ft (1.8 x 2 x 2.4m) footprint and can handle and process web widths from 1.9 to 23.6 in. (4.8 to 60 cm). A service-friendly design with three doors for full front and rear ac- cess makes substrate loading simple. The RollVIA system’s perform-
ance capabilities are complemented by low cost-of-ownership features. In ad- dition to the its compact and service- friendly design, the RollVIA allows for
vertical processing, so that equal plas- ma treatment can be applied to both sides of the substrate, maximizing product quality and throughput. The fast vacuum pump-down and process cycle times further add to its produc- tivity. It is configurable with one, three or five plasma cells to meet var-
ious process requirements. Contact: Nordson MARCH,

RollVIA vacuum plasma system.
ma system for roll-to-roll material handling during flex PCB manufac- turing. The new RollVIA incorporates special vacuum and gas flow technolo- gy, new process controls, updated elec- trode designs, and superior tempera- ture management, with precise control of roll speed, tension, and edge guid- ance for uniform plasma treatment of substrates as thin as 1 mil (25 µm). The RollVIA system is used for
plasma applications, such as surface activation for improved adhesion,
Fujipoly: New Low-Cost General Purpose TIM
Carteret, NJ — Sarcon® GR14A- 50GY from Fujipoly® is a low-cost, general-purpose thermal interface material (TIM) that is offered in sheets or custom shapes to fit specif- ic applications. When placed between heat-generating components and a nearby heat sink, this 0.02 in. (0.5 mm) thick, highly-conformable gap filler pad can transfer heat with a thermal conductivity of 1.6 W/m-K while exhibiting a thermal resistance of 0.61°Cin2/W at 14.5 psi.
Sarcon GR14A-50GY
thermal interface material. To improve material handling
and ease of installation, Sarcon GR- 14A is available in three constructions: tacky surface, hardened surface or re- inforced with nylon mesh. These spe- cial treatments can dramatically re- duce elongation, tearing and damage during cutting and final assembly. The TIM is designed for opera-
tional environments that range from –22 to +248°F (–30 to +120°C). Cus- tomers can order the product in sheets up to 11.8 x 7.9 in. (30 x 20 cm) or spec-
ify an exact size or die-cut shape. Contact: Fujipoly America
