Precision Treatment for Electronic Components

✔ Deburr safely
✔ Cut to a specific depth 
✔ Remove thin surface layers
✔ Texture to a specific Ra

Micro-precision sandblasting is deceptively simple. Unlike traditional sandblasting, this process uses very fine media, small nozzles, and a consistent abrasive feed to deliver a tool with a laser-beam focus and exacting precision. Clean, strip, texture, etch and deburr delicate surfaces without causing dimensional changes to part geometry.

Precision

The micro-scale of our finishing technology creates a tool with pinpoint precision, ideal for working with electronic components as small as a grain of rice to as large as a basketball. What makes it so precise?

  • very fine abrasive (17.5-350 µ)
  • small, focused nozzles (0.018-0.125″)
  • angled, extended and custom nozzles
  • consistent mixture of air and abrasive

Control

Control is at your fingertips! Key variables are adjustable: 

  • blast pressure
  • air and abrasive blend
  • nozzle size and type
  • abrasive type and size
  • working distance from the part

Versatility

Thanks to the wide range of abrasive media available, a micro-precision sandblaster can be a tool that cuts or a tool that textures. 

  • Cut silicon wafers with aluminum oxide
  • Etch epoxy or texture Kapton with sodium bicarbonate
  • Texture sapphire with silicon carbide
  • Remove coatings with wheat starch or plastic media

Automated Systems

Processing a large volume of parts? Need more throughput than a manual system can provide? For more than 45 years Comco’s engineers have integrated up to four axes of motion, multiple nozzles, conveyors, and powerful blasters into automated equipment. Comco automated MicroBlasting systems deliver all the benefits of our manual systems but with greater precision and efficiency for heavy production environments. Both the Advanced Lathe and the JetCenter are designed for the steady processing of precision parts. Each automated system is customizable from a proven platform and delivered as a turnkey solution.

Send us a Sample Part

Many factors contribute to the removal process, but the best way to find out if MicroBlasting is the ideal solution for your challenge is to test a sample part. Our Applications Engineers have the tools on-hand to test different variables, and they have the experience to know where to begin. All test procedures and results are documented in a full lab report returned to you alongside the tested sample parts for evaluation.

Check out our blog entry “We Take Samples Seriously” to learn more about the testing process, and contact a Comco Sales Team member to schedule a sample part test.
