 === Process Specifications and Tolerances ===
-If you’re board passes OshPark’s specs ([[https://docs.oshpark.com/design-tools/eagle/design-rules-files|OshPark .dru file]]), it can be made using our process (see their website for details). However, our process can, in fact, go beyond that in some ways.

 See our [[pcb-help|Knowledge Base]] and [[pcb-tips|Tips and Tricks]] pages for additional information.
+**Note:** If you're considering a design at our theoretical minimum capabilities, first strongly consider whether you need that level of precision. If the answer is still yes, go to the [[pcb-help_pl|ProtoLaser]] (for etching) and [[pcb-help_pm|ProtoMat]] (for drilling) help sections for advice on reaching those new lows.
