What it is

The SUSS MicroTec AS 8 Spray is a semi-automatic spray coater for wet processing and clean applications.[4][1]

The AS 8 Spray handles substrates up to 200 mm or 300 mm in diameter and square substrates up to 6 inches edge length.[1][2][4]

How it works

The AS 8 Spray uses programmable spray and cleaning parameters, dual dispense capability, a touchscreen interface, and an MMC controller software interface.[1][4][2]

Where it fits in the process flow

The AS 8 Spray supports R&D and low-volume manufacturing use.[2][5]

Applications

The AS 8 Spray is used for conformal coating on challenging topographies and complex three-dimensional structures.[2][3][1]
