1. PCB Gerber
In Gerber, the following layers are needed:
  • Top Layer: pcbname.GTL
  • Inner Layer: pcbname.GL2(for 4 layer)
  • Inner Layer: pcbname.GL3(for 4 layer)
  • Bottom Layer: pcbname.GBL

  • Solder Mask Bottom: pcbname.GBS
  • Silk Top: pcbname.GTO
  • Silk Bottom: pcbname.GBO
  • Drill Drawing: pcbname.TXT
  • Board Outline: pcbname.GML/GKO

Notes:1. Gerber file must be RS-274x format.  
      2. Drill file(pcbname.TXT) should be Excellon format.

      3. Gerber file and Drill file(pcb name.TXT) must be put in a same file.  
       4. Board outline is must .

3.Panelization Rules:
A.  There are no extra cost for identical design panelization.

E.g, When you choose“Panelized PCB” is “1” which mean there are only one design board in your PCB Gerber file.


(1)  Please make sure each design is identical when selecting "panelized 1".

(2)  Put the cut lines in outline layer (GKO/GML).

(3)  Highlight the cut lines .

(4)  Put a note beside the V-scoring line if you are using V-scoring for panelized PCB, please see the following picture.


(5)  In Eagel, put in layer 46&50  
(6)  Please note the same sub-boards are over 50pcs (including 50pcs), we will inform you to pay USD10 for the process fee.   

B. we charge the extra cost for multiple design panelization.
E.g , (1) When you choose“Panelized PCBs” is “2”, it is mean there are 2 different sub-boards in your PCB Gerber file and will be requested to pay USD10 for the extra cost(for 1&2 layers). 

      


 
 (2) For 4 layers will be requested to pay USD20 for the extra cost .
 


※  We will inform your to pay 
corresponding fee if you chose the wrong parameters .
e.g. when there are 3 different sub-boards in Gerber file, you should choose “Panelized PCBs” is “3”.   If you choose “Panelized PCBs” is “1”(for 2 layer), we will inform you to pay USD20 for the panel fee .




Please follow below steps to make the Gerber:
Step 1. Put all designs in a same Gerber file.
Step 2. Make sure the cut lines are in outline layer (GKO/GML), and the complete board outline should go all round the edge of the boards.
※    The maximum panelized PCB ( different designs  ) is 9.
      Multi-layer(≥6 layers) board doesn't accept panelization.
Step 3. Choose Panelized PCBs option, ie. 5 different sub-boards = 5 designs
Please note that if there are 2 designs are the same, we still consider that those are 5 designs.  



C. no panelization

(1) Please make sure the 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 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:  no v-cut line in outline layer by make the line as normal silkscreen
  

4.The type of panelization

A. V-scoring

(1) The entire board size should be larger than 7cm*7cm, smaller than 38cm*38cm.

(2) The sub-board size should be larger than 2cm*2cm.

※Please note if the sub-board size is smaller than 2cm*2cm in your PCB Gerber file, we will inform you to pay USD16 for the process fee.

(3) V-cut line only be a straight line.

(4) V-cut line only be cut from edge to edge.


(5) V-cut line must be zero pitch between sub-boards.


(6)The minimum length between circuit wire and the v-cut line as to be equal to or greater than 0.4mm.

(7) The thickness of the board must be greater than 1.0mm.


B. Stamp holes


C. Milled slots( CNC cutting)
