NOTE
From Feb 1st, this Small Batches 2-layer PCB service is discontinued. Please place your order in our new Small Batches 2-layer PCB page, and you will get a favorable price.
Overview
This service provides quick and high quality PCB fabrication experience for worldwide hobbyists.
You will get 50-300pcs, 1-layer or 2-layer large PCB boards per service.
If your files and design meet our requirements, it will be processed and shipped within 6-8 business days (Excluding the Chinese Festival).
Requirements on the design and gerber files:
1.Dimension of the boards should not be larger than the Max value of this service.
There is no limitation on the shape or outline. It means that we do not require the board must be rectangle or circle. Whatever shapes they are, as long as they can be accommodated to the smallest rectangle as below pictures show, then it’s suitable for our pcb service. Take "5cm x 5cm Max" as an example:
2.Gerber files needed for 2-layer PCB boards:
- Top layer: pcbname.GTL
- Bottom layer: pcbname.GBL
- Solder Stop Mask top: pcbname.GTS
- Solder Stop Mask Bottom pcbname.GBS
- Silk Top: pcbname.GTO
- Silk Bottom pcbname.GBO
- NC Drill: pcbname.TXT
- Outline layer:pcbname.GKO or pcbname.DO
Gerber files needed for 1-layer PCB boards:
- Bottom/Top layer : pcbname.GBL/GTL
- Solder Stop Mask Bottom : pcbname.GBS/GTS
- Silk Bottom/Top : pcbname.GBO/GTO
- NC Drill: pcbname.TXT
Note:If soldermask layers are not required, please clarify surface finish for both sides when you submit your gerber files.
3.Outline or shape should be included in at least one layer.
4.All the gerber files must be in RS-274x format, except the drill file should be in Excellon format.
5.
- silkscreen line width (min: 6mil)
- silkscreen text height (min: 32mil)
6.Clarification for panelizing
You can panelize but the design should meet our rules as followed:
(1) There should be no more than 5 sub-boards to fit the size
(2) The sub-boards should only be separated by silkscreen. Using holes or long slots to separate the sub-boards are not permitted.
*Note: You will have to cut the boards by yourself if you fabricate a panelized design.
How to upload Gerber file in your order
1. After you pay the PCB service successfully, please enter my account to check the status of your order list.
2. Click “View Order” to enter your order and upload your Gerber file. Please note that file must be compressed in zip or rar format, and less than 2MB.
You can upload several Gerber files in a same PCB service by choosing different parameters of QTY. For example, if you have purchased three PCB prototyping service, you can upload a Gerber for one of them, and another Gerber for the other two of them.
Your effort will be helpful to make orders processed smoothly and accurately.
