Coating/Marking Rework

We provide comprehensive services for the precise removal and application of coatings, solder masks, legends, and markings on circuit board surfaces. Whether due to design revisions, manufacturing defects, or customer-driven engineering changes, our experienced technicians are equipped to modify board surfaces with exceptional accuracy and control.

Coating and Solder Mask Removal
We use a range of IPC-recommended methods to remove conformal coatings and solder masks without compromising the integrity of the underlying circuitry. Depending on the material type and location, removal may be performed using controlled chemical stripping, micro-abrasion, thermal methods, or precision micro-blasting. Our process ensures that adjacent circuitry remains unaffected, even in high-density areas.

Selective Application and Repair
When new solder mask is required or an existing area needs repair, we apply industry-approved materials matched for thickness, durability, and electrical performance. Whether spot applications or full-area coatings, our techniques restore the board to meet original specifications or updated design requirements.

Legend and Marking Modification
We also offer the capability to remove existing legends or component markings and apply updated text, symbols, or identification codes. Our processes are clean, consistent, and ideal for boards requiring regulatory compliance or version control updates.

From rework and repair to complete surface preparation for board revisions, we deliver reliable, high-quality modifications that meet the demands of aerospace, defense, and advanced electronics applications.
