* Plating is typically avoidable by making vias with a diameter of 40 mil (1 mm). A standard 0.1” header pin can then be pushed through and soldered on both the top and bottom. | * Plating is typically avoidable by making vias with a diameter of 40 mil (1 mm).

* Higher polygon isolation will reduce the chance of bridging to a plane during assembly (since we don’t really offer soldermask). However, it will also increase etch time because more of the substrate will be etched.

+ | * Laser precision is dictated by many things, some (even many) of which are likely beyond your control as a user. Here is a completely-uncomplete list of some of these things (a * indicates things that you, as a user, will not be able to adjust, but get in touch if you think it's a major contributor to any issues you're seeing): | ||
+ | * Flatness of your substrate | ||
+ | * Laser power and other material-specific settings | ||
+ | * Design choices (e.g. spacing, trace widths, substrate, copper thickness, etc.) | ||
+ | * Position of the design on the substrate (left, right, center, etc.) | ||
+ | * Cleanliness of the laser lens* | ||
+ | * Level-ness of the floor* | ||
+ | * Level-ness of the sample plate* | ||
+ | * Filter cleanliness* | ||
+ | * One way to minimize systematic errors from the laser system itself is to do what might be termed a "dose test". This would involve make a very small design that has one or more features at and/or around your actual design' | ||
