PSFL Services
"Thin film surface mount devices"
The PSFL services offered by 3t Technologies include:
PSFL Mask Materials Development
Flxima™ peelable solid film lithography (PSFL) masks are used in conjunction with a range of additive deposition processes (vacuum-based/atmospheric/liquid spray-based/paste draw-down-based) to produce planar and 3D structures and devices. The materials used in the PSFL masking films can be designed to meet specific customer requirements, in addition to 3t designing and producing proof-of-concept and prototyping PSFL ultra-thin film masks for evaluation/use by customers in the construction of their electronic devices.
The photographs above show a split ring monopole antenna produced using a draw-down coating in conjunction with a Flxima™ PSFL peelable ultra-thin film patterned mask. The top left picture is a conductive paint antenna on paper and the top right a silver paste antenna on a 30 micron polythene film. The bottom picture is a PSFL patterned mask where the white image in the centre is where the required conductive coating is deposited to achieve the desired antenna pattern.
PSFL Process RD&D and Prototyping
3t Technologies can research, design, and develop bespoke processing solutions, including early stage proof-of-concept demonstrators, based on its Flxima™ peelable solid film lithography (PSFL) masking technology.
The illustration shown above is a conductive bridge link for manufacturing single-side overlapping circuit metallisation pattern layouts as used for X-Y addressable device applications. The photograph at the bottom is taken from an actual device and shows one method of achieving local conductive track crossover node electrical isolation using PSFL technology.
PSFL System R&D / Process Design and Manufacture
3t Technologies researches, designs, and manages the build of customised processing systems using a network of manufacturing partners. Systems are designed and built to a very high specification, such as the high positional accuracy flatbed processing system developed for a major electronics manufacturer shown below left and laser diode on-cylinder patterning below right.
