Trident Launches Inkjet for Printed Electronics
March 6, 2008 |Estimated reading time: 1 minute
BROOKFIELD, Conn. Trident introduced the 256Jet-D inkjet print head globally, highlighting a durable, serviceable design and stainless steel construction. The print head enables various direct write, printable electronic applications with up to 5× higher resolution than screen printing, according to the company. The 256Jet-D suits printing traces, contacts, embedded passives, and components on PCBs, as well as flexible photovoltaics, fuel cells, and batteries.
Inkjet is an attractive option for direct write, printable electronics because it is additive, said Steve Liker, business manager, Trident. Beyond R&D applications, inkjet is challenged by corrosive and high-viscosity fluids used in electronics printing. The 256D-Jet's stainless steel makeup avoids this problem, he added. The inert stainless steel construction of the 256Jet-D printhead is resistant to the corrosive, aggressive alkaline and acidic materials often used in the deposition of printable electronic components.
Agglomerations of printing materials during the deposition process are accessible via the removable nozzle plate of the 256Jet-D. This targets ease of cleaning. Multiple interchangeable nozzle plates enable distinct drop volume sizes with the same printhead. The 256Jet-D is available in two models: 540 and 5080 picoliters.
It can be heated to 70°C and jets fluids up to 30 cps. The target lifespan reaches 90 billion firings. Its precision drive controller (PDC) is designed to simplify integration by providing the electronics and software drive control of each of the printhead's 256 jets with drop volume precision of ±2%. The 256Jet-D's 256 individually controllable jets allow a greater number of drops to be deposited in one area.
Tight printing tolerances target increased circuit density, reduced PCB size, and lower weight. The system reportedly shortens setup time and eliminates process steps, improves reliability, reduces costs, and protects sensitive substrates by non-contact processing.
Users can print larger components with screen printing followed by printing of smaller, more precise elements with the 256Jet-D inkjet print head, reports Trident. The print head's resolution equals 20 mils.
