PCB Design Rules

PCB Design Rules
Please check the PCB files carefully before placing an order. We are not able to change the Gerber files once PCB fabrication begins.

1. PCB design rules must meet the minimum design parameters


2. Parts ID must be clear and closed to the corresponding part ( Text R2, R3 are closed to the corresponding resistor)

3. Components or connectors with polarity must have polarity marks

4. The package of components on PCB must be the same as that in BOM

5. PCB Gerber files exporting should be in RS-274X format and contain the following file:

  • pcbname.GTL                 Top Layer
  • pcbname.GTS                 Top Solder Mask 
  • pcbname.GTO                Top Silkscreen
  • pcbname.GBL                 Bottom Layer
  • pcbname.GBS                Bottom Solder Mask
  • pcbname.GBO                Bottom silkscreen
  • pcbname.GML/GKO       Board Outline
  • pcbname.TXT                 Drills
  • pcbname.GL2                 Inner Layer (for 4 layer only) 
  • pcbname.GL3                 Inner Layer (for 4 layer only)

6. Special components, please leave a message to us
7. If you have components not need to soldered, leave a message to us.
