Plasma Treatment System

A NORDSON COMPANY

Uniform, High-Reliability Processing

March Plasma Systems Printed Circuit Board (PCB) series isspecifically configured to meet high-to-low production require-
ments. All system components, including the plasma process
chamber, control electronics, RF power supply and PC
controller are housed in a single compact enclosure to
conserve valuable factory floor space.Daily operating expenses, such as the process gases,are minimized through unique design concepts. MarchΒs
staff of PCB experts has developed a comprehensive set
of cost models to help you understand and determine
the best solution for your application.For PCB manufacturing, plasma treatment: Improves inner layer lamination Removes residual resin that smearsalong through- and blind-hole walls Modifies Teflon >
surfaces anddesmears resin on a mixed panel ina single process Cleans carbon by-products from laserformed vias prior to metalization >

Ultimate Process Uniformity

Achieving and maintaining the proper material temperature is
critical to etch rate and uniformity. MarchΒs PCB series plasma
systems maintain panel process temperature control with Tru-
Temp electrodes. Re-circulating fluid Uniformity depends on precise and independent control of allprocess variables, including an even dispersion of process gas and
repeatable gas ionization. March systems are designed to ensure
systematic process control - within a panel, from panel to panel
and batch to batch.Uniform gas dispersion is achieved with Marchs unique vacuumchamber, designed specifically for PCB applications. Features
include a multiple-port configuration and cross pumping. With
cross pumping, gas flow reversal ensures each circuit board panel
is exposed to the same plasma condition.Uniform gas ionization results from an electrode configurationwith multiple power feed-throughs. Energizing the electrodes at
multiple locations ensures a more homogeneous electromagnetic
field. Electrode alignment bars keep the electrodes equally spaced
to ensure uniform plasma for treating both sides of the panel
simultaneously, unlike other systems that require flipping. Non-
conductive alignment bars ensure panels are held vertically parallel
and centered. through the electrodes allowsa temperature set point to be maintained throughout the produc-
tion process. >

CIM Software for Machine andPlasma Environment Control

MarchҒs proprietary Plasma Process Controland Information Management (P >
2 CIM) forWindows NT >
software is specificallydesigned to control and monitor criticalprocess parameters. It provides an intuitive interface with a
complete statistical process control (SPC) package that allows
real-time monitoring of gas flow, temperature, pressure, power
and other process variables. Password levels can be customized to
allow varying degrees of access for operators and engineers.
