It’s never been easy job for providing surface cleaning technology to the demanding industry, perhaps we have sustained the business for 5 consecutive years. DST Technology still comparative new however we received much affirmative reply from our value customer for our effort we deliver. DST Technology has worked with many industry for surface cleaning technology, […]

PVA sponge roller is used in many wet surface cleaning process.  Hard disc substrate and wafer cleaning process are the 2 cleaning processes that require high quality PVA sponge roller products.  Perhaps PVA sponge roller design could play a very important role for achieving better cleaning result. Once a wet surface cleaning process has been […]

Chemical-Mechanical Planarization (CMP) process is the polishing process used in wafer and disc drive industry.  Many efforts have been discussed on setting up an appropriate CMP process however not emphasizes being given on post-CMP cleaning process.  In order to achieve a better surface appearance, CMP engineer should consider both the polishing process and post-CMP cleaning […]

We had discussed about the basic of wet surface cleaning process, before we come to the exact detergent selection for contaminant removal, we would like to reveal some aspects to understand surface contaminants. Contaminants or contamination generate during the manufacture process will cause rejection and product degrade in quality and reliability.  Understand the surface contaminant […]

Surface cleaning is becoming more critical and stringent in many industries cleaning process, this include wafer surface cleaning process and hard disc drive surface cleaning.  The main objective of surface cleaning is removing small particulate and left over on the substrate surface.  The particulate mainly come from previous process such as abrasive and sludge. Field […]
