Okay. Excellent. Thank you, everyone. Good to be here. Thanks for an opportunity to speak here. My topic is critical to performance metrics of functional materials for IMC, so I'm going to try to cover some of the highlights and key points in this 5 minutes that I have here. For those that are not familiar with Sun Chemical, we are the largest ink coating and pigment supplier. I work personally in the division for Advanced Materials. We offer materials for electronics. You can see different applications here on this slide, but I will be really focusing on our suntronic materials for printed electronics and more specifically on in mold electronics. So we the topic is the requirements or requirements metrics, performance metrics for IAM. So as you can imagine, inmold electronics includes multiple process steps and it comes from printing label printing which is typically screen printing. Then it goes to say SMT assembly, it goes to 3D forming injection molding. So it's a quite, quite interesting process.



But then it's not only the materials need to meet, not only performance related to process such as print ability process, stability, stability on, on, on press drying and things like that, but also 3D forming, which is really, you know, you're stretching a conductor. You you're making the cross section smaller, you're thinning the conductor, you're narrowing the conductor. So we really need to make sure that there is no cracking, no outgassing, no shorting between thinning down the dielectric, between crossovers and things like that. And of course, injection molding process involves high temperature and high pressure. So the inks need to withstand the pressure and temperature of the molten resin coming into the tool in terms of application related requirements. You know, materials need to meet the same things that traditional printed electronics requirements, printed electronic materials need to do it right. So electrical resistance, good insulation, low variance in in performance sheet during printing, you know, all of that low defects and of course, end use reliability.


So when it comes to automotive applications, you can imagine a full list of reliability testing that these parts need to go to. Now in terms of some chemicals. So we are as I said, we are the largest ink coating and pigment manufacturer and we offer basically from graphic inks all the way through functional inks, solutions for most electronics. So in terms of decoration and also some auxiliary products such as adhesion promoters, barrier layers, you know, things like that that are needed for the individual layers of the IMY or decorated IMY applicators or labels. We offer our sun tech mold in christenings. We have the DMS, which is the solvent based graphic series. We have DMT. This is a two pack Salomon based graphic inks, and then the DMS series, which is the UV curable enamel decoration. Now we have range of colors, as you can imagine. You can also see on the pictures and custom matches as well. And we now also offer a non conductive decorative dense black, which is extremely important for the capacitors, which is or any circuitry that that needs to be on the label, especially on the same label. Then the electronics from the functional inks we offer conductive inks, silver conductive inks. They are used for interconnects, electrodes, antenna, heating elements, carbon conductive inks, either interconnects or resistors. Our carbon can be also flammable. They also serve carbon serves as a protective layer for connector pads. The dielectric inks certainly serve as crossover insulation, protective over codes and specification for details that are coming out of the plastic parts. Now, we do have again full range of products for either single or multilayer circuits for either one film or a two film molding process. We have we have had our solvent based range for a while and now we are actually introducing some new technologies from some chemical. We have a UV based functional inks, mainly silver. And I'll have a little bit on those in next slides.


So here, one of the key metrics certainly for conductivity is or conductivity and form ability. So we have a range of silvers that have different level of conductivity and form ability and therefore they will be applicable to different end uses such as high conductivity is required for interconnects, antennas, heaters, whereas the lower conductivity or less than 30 less than 25 mill ohm square mil and forming is required for things like capacitive switches and interconnects, lower power application.


A snapshot of some of the forming tools here, and I know I'm in my 5 minutes here, but I'll I'll cover it in maybe 30 seconds here. We have a very high formability for my new the newest UV curable

. We have fine line principle. They're highly flammable as well. So as you can imagine, the finer lines you print the you can do either higher density interconnects or transparent electrodes, heaters, transparent heaters, transparent antenna. You can combine fine line mesh with and with another transparent conductor like the P dot or cents coatings for highly conductive transparent features.

So you can see example of some of the things that we printed that are suitable for. I'm down to around the 20-25 micron level. And last but not least, our high reliability dielectric. You can see our newest generation is highly stable in the 10 to 12 or resistance in the crossover. So you can imagine very fairly thin layer of crossover between the between the layers of the servers with 20 volt bias eight in 2080 585 environmental chambers. So highly stable, highly reliable dielectric as well. So that's it from my side. Some examples of the projects, my contacts. So please let me know if you have any questions or you want to discuss further.
