Technology FundamentalsPolymer Thick Film (PTF) is a field-proven materials and process technology used to create Printed Circuit Boards (PCBs) suitable for small features and layers, which can be printed on top of each other to develop multiple functions. PTF technology can be used in increasingly complex ways, including combing PCB manufacturing techniques to provide automotive component designers with a resource that can enhance product performance, improve reliability, raise quality levels and reduce overall component costs.
Our PTF inks are RoHS compliant and create negligible Volatile Organic Compounds (VOCs) during printing, alleviating the need for specialized ventilation during application. Our silver inks deliver low resistivity, stable physical and electrical properties, generous processing windows based on substrate material, and aggressive miniaturization and increased functionality in electronic circuitry. Utilizing PTF, Methode designs and manufactures cermet and inkjet printed sensor assemblies for a wide breadth of industries including medical, automotive, industrial and military. Standard Products9101 Inkjet Conductive Silver InkMethode's aqueous-based inkjet formulation contains conductive silver nanoparticles and achieves electrical resistance as low as 200 milliohms per square mil within minutes of printing. The ink does not require secondary curing or additional processing and can be inkjet printed onto flexible subtrates such as polyester, synthetic polymer sheets and other coated papers. Offering resolutions as fine as 150 micron lines and spacing, the ink is suitable for use in the printed electronics market, including sensors, flexible displays, photovoltaic arrays, RFID, security and lighting. |
6105 Highly Conductive Screen Printable Silver InkHighly conductive silver ink has relatively low cure requirements including less than 3 milliohms per square per mil on higher temp substrates and less than 5 milliohms per square per mil on lower temperature substrates like polyester, polyimide, other plastics, coated paper and FR-4. These low cure requirements allow it to be cured or dried in standard convection ovens or IR ovens. |
1210 Silver Conductive Via Plugging MaterialA 100% solid system, with no shrinkage on curing, 1210 silver conductive via plugging material provides a high density via plug for low-cost blind and buried vias with or without through-hole plating, where the core boards are fully planar. The material allows PCBs to be designed to recapture much of the real estate that is currently lost to plated through-holes and land patterns. |
Polymer Thick Film and Cermet SensorsOur Polymer Thick Film (PTF) and cermet sensor technology offers compatibility, adaptability, cost and reliability benefits for many applications. Printed on flexible substrates, PTF products can be folded, twisted, bent around corners or bonded to any surface making them ideal for applications where flexibility is needed. Lightweight, compact and environmentally friendly, PTF technology has become the preferred choice for printing electrodes and disposable biosensor components. If the solution requires overcoming tight tolerances and resisting harsh environments, including extreme temperature, solvents and high moisture, cermet hybrids improve product reliability and help maximize real estate space on your designs. |
Flexible Circuits and SensorsDesigned for dynamic environments, our flex circuitry is lightweight, low profile and easy to install. Methode will customize the size, substrate material, resistance values, and tolerances of our flexible circuits and sensors to meet customers' specific requirements. Flexible circuits are printed, not etched, to provide a "green solution" to many applications and the inks can be printed on polyester, polyimide, KaptonĀ®, other plastics, coated paper and FR-4 substrates. |
