A dual-cure diazo high-end photoemulsion for printing line widths under 30 microns - specifically for use in the solar industry and for printed electronics
Within the field of printed electronics, there are numerous applications in which the screenprinting process is used. These include, for example, OLEDs, touch panels and displays; in this context, we can also include LTCC (Low Temperature Co-fired Ceramics), MLCC (Multi-Layer Ceramic Capacitors) as well as fuel cells. At the present time, 20 microns and less can already be screenprinted effectively.
The production of solar cells (both mono and multi-crystalline cells) highlights another field, in which ever thinner, but at the same time, higher fingers of conductive silver are required. In this way, high performance cross-sections and very low light-blocking can be achieved on the silicon wafers. Screenprinting has already proved that 30 µm fine lines can be laid down as standard.
In the product range of screenprinting stencil chemistry, KIWO presents proven and new products for screen printing sheet and hollow glass. In addition to an extensive selection of AZOCOL and POLYCOL quality emulsions for a variety of glass printing applications, KIWO will also show advanced cleaning solutions for machine and manual cleaning processes with its CLEANLINE series.
A very good capillary action, which is advantageous for glass lamination and edge-bonding, is best achieved with low-viscosity adhesives. High viscosities allow selective application of the adhesive.
The bond strength of the different grades was tested on different materials. In addition to high tensile shear strengths when bonding glass to glass and various metals, secure bonding of plastics such as ABS, polyamide or PMMA is also possible.
Coloured UV glass adhesives are available in addition to the colourless versions. This provides the user with a wider variety of applications without losing bond strength, transparency and UV stability.
