AdvantEdge 300

Replenisher

 

Alkaline Etchant for Printed Circuit Boards

 

 

Description

                         

 

AdvantEdge 300 is designed for high volume production of printed circuit boards.  It offers excellent line width control, elimination of slivering, consistent etch rates and superior undercut protection.  The relatively low operating pH of AdvantEdge 300 increases the ability of typical resists to withstand the tendency to soften or lift.

 

AdvantEdge 300 is designed for use in conveyorized spray etching equipment having thermostatic temperature controls and proper ventilation.  The venting system must be capable of creating a slight negative pressure in order to confine ammonia fumes to the etch chamber.
