Conductive ink, gasketting, and shielding applications benefit a great deal from the synergy of motion, sensing, and software. IMAGE ONE below shows traces formed with conductive inks on polyester with an LED placed directly on the ink to form the circuit. Subsequent application of a conformal coat serves to secure the assembly. Note the soldered wires on the polyester. Video one shows resistance traces precisely formed with the benefit of accurate height measurement. Video two shows sprayed RF shielding applied with minimal waste of material. Video three shows a silicone RTV filled with silver used as an EMI shield compound on cell phone housings.

    At 24 inches per second of travel, this CP24 yields terrific throughput! The head dispenses "pats" of hotmelt PSA adhesive to help fixture products on a plastic sheet. The sheets are held on with a vacuum system that detects when a sheet has been removed and when a new sheet has been placed on the pallet. The high speed and the vacuum system combine to yield a throughput rate of less than eight seconds per sheet!

    This system incorporates our ICP platform that can work over dials and conveyors. In this case, parts are presented to the machine via a conveyor and are fixtureless. The onboard vision system performs rotational/translational re-alignment using two openings in the part to properly align the program to the part. This ensures a good spray every time, minimizing overspray that could otherwise contaminate a class-A surface. It also includes a spray-pattern sensor, which verifies fluid flow prior to each cycle.

    This software allows the automated analysis of profile scans. It collects data from a laser system traveling through a region of interest, applies mathematical algorithms to extract features of interest, and reports not only the traditional pass/fail, but also how close we are to pass/fail. This enables our control software to modify machine parameters in response, which allows for the constant improvement of the process in response to environmental and rheological changes.

    New Precision Technology equipment can be outfitted to handle larger meter-mix heads for 2-part dispensing applications. A stronger z-axis stage, geared x-axis stage, and larger gantry shafts enable the use of heavier dispense hardware. A recommended needle tip calibrator will ensure that the necessary meter-mix tube replacements will stay on the mark every time. Dual-pack cartridge dispensing is a dispensing technique that avoids the breakdown and clean-up time of dedicated material lines.
