Design Guidelines

DFM & Gerber Preparation Guide

Avoid common manufacturing delays by adhering to our Design for Manufacturability (DFM) rules.

1. What Gerber file format is recommended?
We accept RS-274X Gerber format as well as ODB++ export. Ensure your ZIP archive includes Top/Bottom Copper, Solder Mask, Silkscreen, Drill file (.DRL), and Board Outline layer.
2. What is the minimum trace and space rule?
Our standard process supports 4/4 mil (0.10mm) trace width and spacing. For high-density designs (HDI), we support down to 3/3 mil (0.075mm).
3. How should board outlines & cutouts be demarcated?
Keep board outlines on a dedicated Mechanical layer (Mechanical 1 / GKO layer) drawn with a 10 mil line width. Ensure routing clearances of at least 8 mil from trace to edge.
4. What testing procedures are performed on finished boards?
Every batch undergoes 100% Flying Probe Electrical Testing (E-Test), Automated Optical Inspection (AOI), Solderability testing, and Metallographic cross-sectioning upon request.
