Product Specification
AdvantEdge 400
Replenisher
Alkaline Etchant
for Printed Circuit Boards
Description
AdvantEdge 400 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 400 increases the ability of typical resists to withstand the
tendency to soften or lift.
AdvantEdge 400 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.
