Conformal Coating Operator

About the Role

As a Conformal Coating Operator at Rocket EMS, you will play a key role in protecting high-reliability PCB assemblies by applying, inspecting, and verifying conformal coating materials. You’ll work with production, engineering, and quality teams to ensure all boards meet customer, IPC-A-610, and internal workmanship standards. This position requires strong attention to detail, steady hands, and the ability to follow precise documentation and masking requirements in a fast-paced manufacturing environment.

Responsibilities

• Review job documentation, including MPIs, assembly drawings, ECOs, masking instructions, and customer requirements prior to starting work.

• Mask boards accurately using tapes, dots, boots, and custom masks to protect keep-out areas from coating material.

• Operate conformal coating equipment such as selective coating machines, spray booths, or dip-coating systems, depending on job requirements.

• Verify coating material viscosity, mix ratios, and application parameters; document measurements as required.

• Apply conformal coating (urethane, acrylic, silicone, parylene, or other materials as specified) according to defined thickness, coverage, and curing requirements.

• Inspect coated assemblies for proper coverage, thickness, defects, and compliance with IPC-A-610, customer specifications, and workmanship standards.

• Identify and correct coating and masking defects; escalate recurring issues to the Lead, Engineer, or Supervisor.

• Perform rework or touch-up coating as needed using brushes, spray guns, or approved tools.

• Cure assemblies using appropriate equipment (ovens, UV cure systems, etc.) and verify completion per process standards.

• Complete first-article verification and in-process inspection forms when required.

• Maintain clean, organized work areas and strictly follow ESD, FOD, and chemical handling safety procedures.

• Record production data, coating material usage, and pass-down information accurately.

• Support cross-training and assist in other production areas as directed by Supervisor, Engineer, or Manager.

• Participate in 5S and continuous improvement initiatives to enhance process quality and efficiency.
