MicroBlasting Technologies for Electronic Components
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.

What can be achieved with MicroBlasting?
MicroBlasting is an effective solution for electronics industry applications including conformal coating removal, decapping ICs, deburring PGAs and wave guides, texturing flex circuitry and removing excess epoxy from probe rings.
Conformal Coating Removal
Selectively remove conformal coating from printed circuit boards without damage to the board.

Semiconductor Devices
Remove microns of surface material, create a sloped edge, without vibration or micro-cracking.
Read More
Wave Guides
Remove fine burrs from edges and openings of complex wave guide components without introducing dimensional changes or radiuses.
Flex Circuitry
Delicately texture the surface of rigid and flexible substrate materials to improve the bond, increasing the peel strength of the material when it is attached to other substrates.

Brittle vs. Ductile
The coating removal process uses the abrasive qualities of MicroBlasting to carefully erode layers of unwanted material from a base substrate. The process takes advantage of the different physical properties of the two layers. Brittle materials can be removed from soft ductile layers, or soft ductile layers can be removed from brittle layers.

Static Sensitive Application
You might think micro-precision sandblasting, or MicroBlasting, is an unlikely tool for coating removal on static sensitive circuit boards and electronics. You might expect all that dry air and abrasive to kick up a spark, create a mess, or mar delicate compositions. However, with the right adaptation to your equipment, you can greatly reduce the risks associated with ESD. MicroBlasting provides a gentle, precise and controllable approach to selectively remove parylene, epoxy, polyurethane, silicone, acrylic and more without danger.

Nozzle Angle
Abrasive particles transfer the most impact energy when the nozzle is positioned at 90° to the target, but abrasive particles ricochet at this direct angle, crowding and slowing the stream. When cleaning or eroding surface material, hold the nozzle at or near a 75° angle to the target.

Read MoreThe Manual System
The AccuFlo® produces a steady flow of abrasive which ensures consistent results. It processes parts faster than most traditional micro-abrasive blasters, and it does so with greater powder efficiency. The AccuFlo is able to handle a wide-range of abrasives and suits most MicroBlasting applications.
