Jetting Valve Technology Superior to Needle Dispensing
Compared to traditional needle dispensing technology, jetting valve technology is the most effective method for quick and accurate fluid dispensing. Injection technology has many advantages, it provides a combination of high-speed, high quality and low cost production for fluid dispensing processes. Instead of putting focus on getting the application done, jet dispense technology focuses on performance, providing applications like underfill, potting and encapsulation with more precision than ever before.
Improved Fluid Dispensing Speed and Accuracy
Non-contact jetting valves offer a significant advantage over traditional needle dispense valves. Jetting Valve Dispenser precision reaches to 200µm with dot diameter or line width as small as 250µm and volumetric dispensing down to .0036µl. Minimum space between lines is 180µm and maximum fluid dispense speed is 200 dots/second.
