| + | ===== PCB Units ===== | ||
| + | PCB handles metric and imperial units in the following way: | ||
| + | * The base Imperial unit is the "centimil", or 1/100 of a thousandth, or 1/100,000 inch, or 0.00001 inch. | ||
| + | * Allowable imperial value range: "0.04" (0.0000004 inches) to approx. "78740000" (about 78-3/4") | ||
| + | * The base Metric unit is 1nm (one nanometer). PCB parses in metric if the number has a "mm" behind it. | ||
| + | * Allowable metric value range: "0.000001mm" to "2000mm" | ||
| + | * NOTES: | ||
| + | * use "mm" after number to specify metric | ||
| + | * imperial and metric may be mixed within a footprint (!) | ||
