DP Seals has created a special carbon-enriched carboylated nitrile for
the nozzles tips used in surface mount pick-and-place machines. These
tips cushion components against damage during assembly. The custom blend
was produced for DP's customer, Metro Technologies, and has demonstrated
exceptional durability and abrasion resistance, while meeting the
industry's all-important static electricity management requirements.
Ranging in size from 3 to 7mm diameter, the tips are moulded to better
than +/-5 micron accuracy and precision bonded to the nozzles.
Original equipment nozzles are frequently replaced by cheaper
second-source components. Metro's Optima range, which incorporates the DP
moulding, is now claimed to outperform not only second-source
equivalents, but also OEM nozzles. Following trials at a number of
manufacturing sites in the USA and Far East, Optima nozzles achieved up
to 14% pick-and-place performance improvements against OEM, and 41%
against second-source nozzles.
