# Units of Conversion for PCB Production

- Jul 26, 2017-

All units before the conversion, we often need to use the work. Each guest is accustomed to the use of different units, so the production requirements in the circuit board production unit is not the same value, this time we will use the unit conversion. The following order to work in the need to often use the unit conversion, to facilitate the reference collection.

Common unit conversion:

1 mil = 1/1000 inch = 0.00254 cm = 0.0254 mm

1mil = 25.4um

1um (1 micron) = 0.001mm

1um (1 micron) = 0.001mm (0.001mm)

1um = 0.03937 mil

1um = 40uin (some companies that micro-inch for wheat, in fact, micro-inch)

1um (1 micron) = 0.001mm

1 mil = 0.0254 mm (conversion: 1 mil = 1/1000 inch = 0.00254 cm = 0.0254 mm)

Thus: 4mil / 4mil = 0.1mm / 0.1mm line width line distance

1mil = 25.4um

1mil = 1000uin mil mils sometimes into silk

100 mil = 2.54 mm

1mil = 0.0254mm

1 mil (mil) = 0.001 inch

1um is equal to how much u "?

which is:

1um (micron) = 39.37μ '' (approximately 40μ '')

1 μm = 1 uinch = 0.0254 μm (μm) = 25.4 mm (mm)

1um (micron) = 0.001mm (mm)

1OZ is equal to how much UM?

1oz (ounce) = 35um (micron) = 28.35g / sq ft

1oz (ounce) = 28.35 grams, this is an imperial unit

1oz (ounce) = 28.35 g / ft2 = 35um micron
