RCT Advantage
DFM-focused fabrication support.
RCT reviews the details that matter before boards are released to production.
Stackup
Layer build, dielectric, copper, and impedance requirements.
Mechanical
Outline, slots, bend areas, and tolerances.
Surface finish
Match finish to assembly needs, storage, and reliability.
Panelization
Review rails, tabs, fiducials, and assembly constraints.
Send files for fabrication review.
RCT can evaluate your PCB fabrication requirements and provide quote guidance.
