I agree that the documentation should be used and not necessarily the silk screen. The silk screens can be a first line of defense, but nothing beats the proper documentation. Years ago I visited a contract manufacturer that a friend was working at

Seen it. We use a lead free process, sometimes our supplier will use a lead process silk screen that burns at a lower temp. The HASL coat was still SN100CL.

As a stencil vendor to some assembly houses and small in-house assembly shops, both without CAD people rushing to put the paste layers (if they even generate one) into stencil friendly format, the silk screen is the only communication tool we have to

We have had poor solderability from silk screen being on pads, but have never measured the conductivity.

Most of us, here on SMTnet, are either assemblers or sale types. Assemblers use stencils [metal foil, secured in a frame] instead of silk screens. Fabricators use silk screens in various photoimaging processes for applying etch resists, solder mask
