We accept Gerber Files and direct CAD format in Eagle Cadsoft or Protel DXP. Gerbers File is a combination of various layers and drill datas on a PCB design. Depending on the CAD software used, gerber extension can vary greatly. Sometimes they
may appear confusing but it is generally broken down into the individual layers of a PCB. Gerber layers : 1. Drill Data (example extension *.drl, *.drd) 2. Top Copper Layer (example extension *.cmp, *.gtl) 3. Bottom Copper Layer (example extension *.sol, *.gbl) 4. Top Soldermask Layer (example extension *.stc, *.gts) 5. Bottom Soldermask Layer (example extension *.sts, *.gbs) 6. Top Silkscreen Layer (example extension *.plc, *.gto) 7. Bottom Silkscreen Layer (example extension *.slc, *.gbo) 8. Board Outline (example extension *.dim, *.gko) 9. Internal Layers (example extension *.g1, *.g2) (4 layer board will have 2 internal layers while 6 layer board will have 4 internal layers) Recommended Gerber Data Format : Format / Dialect Resolution Format We also accept CAD format directly from Eagle Cadsoft or Protel DXP If you need further assistance regarding Gerbers and CAD requirements, please contact
