PCB-Series Plasma Treatment System - 18446 March

® 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. March’s 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. March’s 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 March’s 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

March’s 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. PCB 2800 Plasma Treatment System
