  • Inner Layer: pcbname.GL3(for 4 layer)
  • Bottom Layer: pcbname.GBL
  • Solder Mask Top: pcbname.GTS
  • Solder Mask Bottom: pcbname.GBS
  • Silk Top: pcbname.GTO
  • Silk Bottom: pcbname.GBO
  • Drill Drawing: pcbname.TXT
  • Board Outline:pcbname.GML/GKO
4. Gerber file requirements:
  • Select EXCELLON instead of Gerber_RS274X when choosing the Device for Drill Data. Seeed_Gerber_Generater_2-layer for 2 layers andSeeed_Gerber_Generater_4-layer_1-2-15-16 for 4 layers are suggested to download for generating the gerber file when using Eagle to design.
  • For 4-layer PCB, in gerber, copper must be shown in layer 1, 2, 15, 16.
5. Panelization Rules:

If you want

a.apanelized array with V-cut, please make sure each pieces is the same
  • a) put the v-cut line in outline layer (GKO/GML)
  • b) highlight the v-cut line
  • c) put a note beside the v-cut line, please see the following picture.
  • d) In Eagel, put in layer 46&50 panelized different boards together, please note that the board will be shipped separately.

Step 1. Put all designs in one Gerber file.

Step 2. Make sure the cut lines (slot) are in outline layer (GKO/GML), and the complete board outline should go all round the edge of the boards.

Step3. Choose Panelized PCBs option, ie. 2 different boards= 2 designs, maximum is 5 designs.

If there are 2 designs are the same, we still consider that those are 5 designs. v-cut
  • 1) Please make surethe complete board outline should go all round the edge of the boards.
  • 2) No cut line in Outline layer (GKO/GML), please see the following picture
  • 3) You will still get 1 complete board WITHOUT any cutting no matter you put different designs or same design boards here.

4) If you want to use silkscreen to separate the boards, put the line in silkscreen layer.

Tips: a) no v-cut line in outline layer b) make the line as normal silkscreen

  • One service, one design file.
  • Submit your design in either EPS or CDR format. Your design file must be less than 10mb.
  • The parts need to be flat. If you want to make 3D parts, you could combine multiple 2D pieces.
  • If you have parts that taper to a thin, sharp point, make sure the the two converging lines of the sharp corners are no less than 0.05cm apart.
  • Plastic thickness may vary by + or – 10%.
  • The plastic sheets come with a protective masking on both sides to protect its surface during the cutting.
