Conformal Coating Removal That is Precise, Safe and Cost-Effective

Conformal coating can be broadly classified as either plastic or resin material that is applied to electronic devices to provide protection from various forms of environmental contamination. The coating must be removed—either entirely or in specific areas—when a component fails, to expose a test point, or for reverse engineering.

How Microblasting Works

Unlike traditional sandblasting, MicroBlasting uses a very fine abrasive media mixed with compressed dry air. This mixture propels through a miniature nozzle designed to increase the stream’s velocity and give it a laser-beam focus. The combination of particle type and velocity allows Microblasting to quickly etch through conformal coating without damaging the solder mask or the components underneath.

  • Wheat Starch

    Wheat starch is the softest abrasive available for conformal coating removal applications. It has soft particles with shard-like edges, which make it excellent for abrading thin, pliable coatings like parylene and acrylic.

  • Plastic Media

    Plastic media is a gentle abrasive and works well against the broadest range of coatings. It is the utility player of conformal coating removal abrasives. It quickly removes parylene and thick coatings. It is slightly harder than wheat starch, and its particles are smaller than walnut shell. Plastic media is treated to reduce electrostatic discharge.

  • Walnut Shell

    If plastic media is not aggressive enough, try walnut shell. This is still one of our soft abrasives, so it is forgiving of operator error. But it features a slightly larger particle size with slightly sharper edges, which gives it greater cutting power.

Nozzle Selection

Conductive nozzles are recommended for conformal coating removal applications. A conductive nozzle eliminates any charge that could build in the abrasive hose. Conductive nozzles are part of our Hi/Performance line.rnrnDownload our Microblasting Nozzles and Abrasive Media guide to the right to see our wide range of nozzlesrn

A Complete MicroBlasting Solution

Any components that are sensitive to electrostatic discharge should be processed in the ProCenter Plus™ with ESD Control. This unit delivers maximum protection against an ESD event.

Features that Neutralize ESD

The Ionizer Bar

Floods the entire work chamber with ionized air to neutralize static build-up. Built-in sensors monitor the effectiveness of the ion flow and indicator lights alert the operator to any changes in operation.

Grounded Handpiece and Conductive Nozzle

Limits the potential for a charge to travel to the board from the abrasive hose. The conductive nozzle and handpiece provide a conduit for static, sending it straight to the grounding jacks instead of onto a PCB.

Grounding Jacks

Provide convenient connection points for a static control wrist strap, the edge grounding bar, the conductive handpiece, and the needle probe.

Edge Connector Grounding Bar

Grounds all edge pins on boards that have edge connectors. This bar is made of conductive rubber material and connects to a grounding jack on the floor of the ProCenter Plus.

Needle Probe

Pierces through the coating and grounds a target trace when the defect is known to be an open trace with no conductive path to ground.

Blacklight

Installed for coatings that contain UV markers, clearly identifying where the coating has been removed on the board
