What additional information do you include in your PCB/Gerber?
« on: February 23, 2018, 06:35:51 am »
I am finally spending some time cleaning up our templates for schematics, BOMs and PCBs and I'm curious what additional information people include on their PCBs and ultimately Gerbers.

We have a template that has our company name, address, a revision, project name, date, drawn by, as well as some things that are never used like drawing number (we don't have a system in place for these) which usually either stay default or are deleted before generating output for production. We also have a border, which I'm skeptical about it's usefulness but have left it in place.

I'm curious what people include or have found useful in the past?

Added to PCB Files:

Either on the top component overlay or on the top or bottom copper layers:

A/ PBC File Name including revision number

ie XMO_v1

B/ Date of the design when the Gerber files are being generated

ie 23/02/2018

C/ The copyright symbol to retain the ownership of the layout

ie (C)

D: Your Company Name or your Website URL

Added to Gerber Files:

Absolutely NOTHING.

If you want to point out slotted holes or gold fingers etc to the board shop, do this on one of your mechanical layers, generate the Gerber for the mechanical layer & when you place your order make special mention that the mechanical layer contains pcb board manufacturing instructions that must be adhered to.
I also sat between Elvis & Bigfoot on the UFO.

At work we add on Drill Drawing layer (Altium Designer) requirements from PCB manufacturer like:
- for ENIG, gold thickness and minimum thickness for the low stress nickel under gold
- material type: FRxxx with TG xxx
- plating thickness, minimum PTH barrel thickness
- what kind of soldermask to use: matte or transparent/glossy
- information's about controlled impedance (when it's the case)
- if non-functional copper thieving is allowed in open areas
- if via holes need annular ring or tangency only
- if they are allowed to add teardrops or not


On the PCB itself (Top Overlay) we add:
- company logo
- if it's ROHS compliant
- part number and revision

I write the rectangular dimensions of the pcb on a pcb layer, like top document. This is to fill out quote information.
