Open Parts Library
Introduction
OPL v1（Open Parts Library v1） is a package of 100+ kinds of components. Such components are commonlyused, quality reliable, DFM friendly and have sufficient stock. Also, their eagle library is free to download. This little package can greatly increase the efficiency for design reference and supply chain optimization. OPL v1 is a collection of components, which are highly recommended and commonly used in open source community. Including IC, resistor, capacitor, inductor, diode, transistor, crystal oscillator, connector and fuse, etc.

 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_2layer for 2 layers andSeeed_Gerber_Generater_4layer_121516 for 4 layers are suggested to download for generating the gerber file when using Eagle to design.
 For 4layer PCB, in gerber, copper must be shown in layer 1, 2, 15, 16.
5. Panelization Rules:
If you want
a.apanelized array with Vcut, please make sure each pieces is the same
 a) put the vcut line in outline layer (GKO/GML)
 b) highlight the vcut line
 c) put a note beside the vcut line, please see the following picture.
 d) In Eagel, put in layer 46&50
b.to 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.
c.no vcut
 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 vcut line in outline layer b) make the line as normal silkscreen

Laser Cutting Service
1. Read this first
 We can ONLY do Laser cutting for now. Any Laser engraving is NOT accepted.
 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.
 Your order will be processed and shipped in 34 days (Excluding the Chinese Festival).
2. Materials
We begin with one material. There is no doubt we will gradually add more materials into the list.If you want some other colors which are not listed here, welcome to tell us by dropping a line to order(at)seeedstudio.comMaterial Number  Thickness  Opacity  Color  Type
