With the exception of some solder paste and conductive silver materials, dispensed fluids are seldom electrically functional parts of the devices; rather, they increase reliability or are structural.
For this reason, automated fluid dispensing is often considered a anecessary evil' in design and subsequent manufacturing. Adding a fluid dispensing process to solve a reliability problem after designing the electronics precipitates a design change. Inevitably, the change increases the part size. For a decade I've helped customers try to make room for the fluid.
That's why jetting technology is exciting! Automated dispensing equipment has evolved, but the technology for putting the fluid on the parts has changed very little. A pump extrudes material through a needle or nozzle to lay the fluid on the desired part. Jetting changes that.
Jetting lets the designer (and manufacturing engineer) place fluids in areas needles and nozzles cannot reach, and do it faster. Sometimes, an order of magnitude faster. Differing from piezo and thermal jetting, mechanical jetting dispenses fluids up to 500000 centipoise. This covers most fluids used in automated dispensing. Adopting jetting technology enables new designs and lowers costs. Consider it for your next product to give it the competitive edge it needs to survive.
