Advanced Automation

One of Essemtec’s advantages is the ability to adapt our core platforms to build advanced automation solutions for micro system assemblies. The combination of dispensing/jetting fluids and placing miniature components with high z-axis stroke can be expanded to build micro cameras, micro lens assemblies, MEMS sensor packages and so forth. Also, integrated microwave assemblies (IMAs), EMI shields, etc. are easily and automatically built with high repeatability. Moreover, 3D over-molded lead frames, which are heavily deployed in automotive solutions, are easily populated using Essemtec’s work cell concept.

The SW allows for an unlimited number of dispense and placement cycles on any substrate or work holder. A typical sequence would be:

  • 1. Insert empty tray
  • 2. Pick bottom shell and place in tray
  • 3. Dispense first fluid in 3D pattern
  • 4. Pick electro/mechanical components and place in bottom shell
  • 5. Dispense second fluid
  • 6. Pick top shell and close housing
