FRANKLIN, MA – The US Patent Trademark Office has awarded Speedline Technologies a patent for its dual head dispensing technology.

The patent claims are based around detection of panel rotation and the ability of the system to automatically switch to an asynchronous dispense mode. This functionality ensures that both heads dispense accurately on PCBs within a skewed panel, Speedline explained in a press release.

In the patent abstract, the inventor claims "a method of dispensing viscous material on an electronic substrate, the method comprising: delivering a first electronic substrate pattern to a dispense position; delivering a second electronic substrate pattern to a dispense position; aligning the first electronic substrate pattern with a first dispensing unit coupled to a beam by a carriage device configured to move the first dispensing unit in a X axis direction and a Y axis direction; positioning the second dispensing unit a predetermined distance from the first dispensing unit by an adjustable bracket that directly couples the second dispensing unit to the carriage and moves the second dispensing unit relative to the first dispensing unit; dispensing material from the first dispensing unit at desired locations on the first electronic substrate pattern; and dispensing material from the second dispensing unit at desired locations on the second electronic substrate pattern."

The patent number is 7,833,572 and the inventor is Hugh Read.
