EAGLE cad helpers for JLCPCB (https://jlcpcb.com) production and assembly services
Rules and scripts have been tested under EAGLE cad 9.5.
They're provided AS IS, with no warranty. Any feedback is greatly appreciated and can be provided via issue tickets.
This repo is not endorsed by JLCPCB.
Copy each file in their respective folders (USER_HOME/Documents/EAGLE/).
- cam/jlcpcb-2layers.cam: 2-layers version
- cam/jlcpcb-4layers.cam: 4-layers version
The jobs follow the naming guidelines defined here: https://support.jlcpcb.com/article/29-suggested-naming-patterns They also include tCream/bCream solderpaste layers that could be used for the stencil service.
- design rules/jlcpcb-2layers.dru: 2-layers version, 35u copper, 1.6mm board thickness
- design rules/jlcpcb-4layers.dru: 4-layers version, 35u/17.5u copper, 1.6mm board thickness
Mainly based on EAGLE's standard design rules, it adds the declared JLCPCB's capabilities listed here: https://jlcpcb.com/capabilities/Capabilities
Note: annular ring for pads aren't minimal, in order to allow proper solderability of TH components
- ulps/jlcpcb_smta_exporter.ulp: BOM (bill of materials) / CPL (pick&place) exporter
The smta exporter ULP can be used to quicken the process of creating the required files for the SMT assembly service.
Observe the following:
- it must be executed from the board editor
- it asks for a directory where to export the two files
- the two resulting files will be named
<boardname>_bom.csvand<boardname>_cpl.csv - components rotations are sketchy and must be visually checked on the online gerber viewer once uploaded the files
The ULP can extract LCSC part ordering numbers from the packages attributes. The attribute must be named LCSC_PART or LCSC and it should contain the order code found in the parts library https://jlcpcb.com/client/index.html#/parts (eg: C25804).
The ULP can also manually rotate the angle in the CPL output file. The attribute must be named JLC_ROTATION. For example, if a part's angle in set to 90 and it's attribute JLC_ROTATION is set to 180, the angle in the final CPL file will be set to 270.
Top and/or bottom assembly can be chosen directly during the ordering process, JLCPCB will use the CPL file to determine which side the designator has been placed on.
In case a part should not be exported into the BOM/CPL, add an attribute called "DNP" (the value is not relevant and can be an annotation for the reason for the exclusion). The POPULATE flag is also taken into consideration for filtering out parts that shouldn't be part of a specific variant.
