Understanding the footprint position file--reworked by JLCPCB

[hildogjr]

I had working in some fixes for a Pcbnew JLCPCB plugin for v5.99/v6

Fixing plugin JLCPCB

There is some minor issues that I want to fix but may be ready for some try, if someone want.

That make the work of converting the position files.

Basically, KiCad uses a “A” and JLCPCB a “B” variation of the standard of SMD position (if someone search, it is mentioned in a past thread about JLCPCB). They basically change which quadrant the pin 1 should be in the library drawing for each package format.

JLCPCB BOM and Pick and Place

I am interested in exploring how my KiCAD designs SMT could be fabricated by the new JLCPCB service. I have finally wrapped my head around the very convoluted and non intuitive BOM process KiCAD has, not sure that the final BOM format is suitable for JLCPCB? Is there anyway to generate a pick and place file that would be suitable for JLCPCB? Anyone here been successful with interfacing with JLCPCB SMT fab service?

Change library is a bad approach, since the KiCad library is well checked for the library manteiners and community, and the conversion A<>B standard is straight forward (see the plugin have a file with this conversion).
