Depending on the printing media in use, both water and solvent based cleaning products are used for cleaning the undersides of SMD stencils in the printing machine. More Information

 

KIWOCLEAN EL 9100

Extremely efficient cleaning of SMD solder units – spray on, wipe off, all done!

This newly developed and widely used product effectively removes colophony, fluxing agents and degassing residue from printed circuit boards without attacking surfaces. More Information

Accurate bonding with printable adhesives

Thanks to further developments in quality, screenprintable pressure-sensitive adhesives have made their mark in many industrial applications. Which screenprintable pressure-sensitive adhesives are available on the market and where are their preferred areas of application?

 

For processing liquid adhesives, the screen printing method has established itself alongside the conventional systems like curtain coating, spraying, anilox and knife. The specific advantages of using the screenprinting method for processing adhesives was already recognised in the early 1970’s. Today pressure-sensitive adhesives, which have been printed on substrates can be found in many industrial areas of application, as for example, the automotive industry, household white goods and the electronic industry. More can be found in the production of optical displays as well as the advertising and sign making industry.

AZOCOL Z 140 - All-round, high-quality photoemulsion

Dual-cure diazo photoemulsion

AZOCOL® Z 140 is used for the production of high quality screen printing stencils. Due to its excellent imaging properties such as resolution, sharp print shoulder and tonal value replication, it is ideal for printing finest half-tones. Whatever you are printing - glass, membrane switches or graphics - AZOCOL Z 140 is a genuine all-rounder.

The adhesive’s fast curing is a special advantage giving short cycle times.

SBQ-based Screenprinting Emulsion Technology

Dr. Roland Studenroth, KISSEL + WOLF GmbH

 

 In the course of the 80s, a new technology from Japan edged its way into the screenprinting market. This was the technology of single-component emulsions based on SBQ. The abbreviation SBQ is derived from the product name "Stilbenium quarternized" and specifically means that a water-soluble, UV light-sensitive stilbene group is chemically bonded with the polyvinyl alcohol (PVA) contained in emulsions (see Figure 1), so that for light sensitizing a second component, such as diazo is no longer needed. Because of it being a single-component product, the SBQ emulsion technology first experienced a boom, but also contributed at the same time to the perfectioning of the alternative dual-cure diazo technology. Today both technologies are firmly established in the market and complement each other, i.e. there is dual-cure technology also found in SBQ-sensitized products and to achieve specific properties, SBQ emulsions can be additionally mixed with diazo compounds.
