Teflon Dispensing Needle: The “Invisible Assistant” for Precision Dispensing

In the field of electronics manufacturing, semiconductor packaging and other precision industries, dispensing operations are like the “art of micro-sculpting”, and Teflon dispensing needles, is the key to achieving this art of the Teflon dispensing needle is the key to realise this art.

First, the secret of “non-stick”

Teflon, scientifically known as polytetrafluoroethylene, which has a super powerful characteristics -- low surface energy. Simply put, it is difficult for fluid materials like glue to “take root" on its surface. When ordinary needles are used for a long time, the glue is easy to remain and solidify, clogging the needle and affecting the dispensing accuracy. But Teflon needle is not the same, glue on its surface like a "slide", flowing smoothly, but also do not love to leave ‘aftermath’, greatly reducing the needle clogging, glue pulling and other issues, so that the dispensing process is more stable.

Second, accurate dispensing "operation logic"

dispensing operation, usually with the help of air pressure or precision pump valve to provide power to push the glue from the syringe to the needle. Teflon needle is like a precise "conduit", using its own material of low friction, non-sticky, so that the glue is uniform and stable outflow. For example, in chip packaging, to put a very small amount of glue precisely coated between the chip and the substrate, Teflon needles can be strictly in accordance with the set parameters of pressure and time, to control the flow of glue, to achieve "nano" dispensing precision, to ensure that the chip bonding is strong and will not be overflowed to affect the performance of the glue .

Third, adapt to a variety of scenarios, unlocking the new possibilities of dispensing

Whether it is the electronics industry to coat circuit board pads with flux, or in the LED encapsulation of fluorescent adhesive dripping, or the production of medical devices in the fine injection of adhesive, Teflon dispensing needles can be ‘competent’. It is suitable for different viscosity of glue, from thin organic solvents to thick silicone, can be smoothly extruded with the characteristics of Teflon. And chemical corrosion resistance, in the face of various types of glue, solvent, their own material stability is not eroded, to extend the service life and reduce the cost of production supplies.

Small Teflon dispensing needles, with unique materials and exquisite design, become the ‘invisible hero’ behind the precision manufacturing, supporting the electronics, semiconductor and other industries to more miniature, more accurate direction of continuous progress, in the invisible minutiae, guarding the quality of the product and production efficiency.
