Trident launches 256Jet-D inkjet printhead for printed electronics

Connecticut, USA. - Trident, the global leader in inkjet printhead and ink production for commercial applications, has announced the launch of its new, versatile "256Jet-D"™ inkjet printhead. Available worldwide, the 256Jet-D features a durable, serviceable design and stainless steel construction which allows for printing of a wide variety of direct write, printable electronic applications with up to five times higher resolution than possible with screen printing. Trident's 256Jet-D inkjet printhead can be used for printing traces, contacts, embedded passives and components (resistors, capacitors, inductors, etc.) on printed circuit boards as well as for the printing of flexible photovoltaics, fuel cells and batteries among other applications.
"As an additive process, inkjet is a very attractive option for direct write, printable electronics," explained Steve Liker, Business Manager at Trident. "It allows manufacturers to print exactly the amount of material they need, exactly where they need it, saving significant time and expense when compared to subtractive printing methods that waste valuable printing materials. Until now inkjet printing for direct write has been limited to R & D labs, partly because most inkjet systems have not been able to handle the corrosive and high viscosity fluids needed for many printable electronic applications. The stainless steel 256Jet-D provides this industrial durability and makes inkjet printing a very valuable proposition for printable electronics."
The 256Jet-D revolutionizes digital electronics material printing with its durable, serviceable design. Whereas previously agglomeration of printing materials during the deposition process meant that printhead nozzles would clog and printheads needed to be discarded and replaced, the serviceable nozzle plate of the 256Jet-D can simply be removed, cleaned and reassembled. In fact, end users can purchase multiple interchangeable nozzle plates in order to print distinct drop volume sizes with the same printhead. The 256Jet-D is available in two models enabling the printing of two distinct drop volume ranges: 5 - 40 picoliters and 50 - 80 picoliters in size.
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. With the ability to be heated to 70°C and to jet fluids up to 30 cps, the 256Jet-D can print materials with twice as much viscosity as traditional inkjet systems, giving users wider flexibility in material loading and fluid formulation. Its rugged industrial design gives the 256Jet-D printhead an industry-leading lifespan of 90 billion firings.
Along with the 256Jet-D Trident offers a high-performance "Precision Drive Controller" (PDC) which simplifies customer integration by providing the electronics and software drive control of each of the printhead's 256 jets with drop volume precision of plus or minus 2%. The 256Jet-D's 256 individually controllable jets allow a greater number of drops to be deposited in one area, thereby increasing productivity.
Trident's 256Jet-D inkjet printhead also has several application-specific benefits:
- Printed Circuit Boards: The ability to print small components such as traces, resistors and capacitors with small drop volume and high resolution makes it possible to increase circuit density, or to reduce the real estate and weight of the circuit board. This high-resolution, direct write printing also saves in process steps, speeds set-up time, improves reliability through the elimination of solder joints, shortens electrical connections, reduces cost through automation, and enables non-contact printing for sensitive substrates.
It is also possible for users to print larger components with screen printing followed by printing of smaller, more precise elements with the 256Jet-D inkjet printhead which is capable of 20 mil resolution print (5 times higher resolution than the 100mil resolution possible with screen printing).
- Batteries: Inkjet printing enables layering of key materials needed to print very small batteries.
- Photovoltaic: When printing solar cell contacts it is necessary to minimize contact widths so that light is not blocked. Inkjet printing of photovoltaic contacts allows for the smallest possible high-resolution contact printing.
