For personnel engaged in the PCB industry, it is inevitable to encounter various units of data. Conversion between various units is often needed, and it is often necessary to search for conversion values. For the convenience of PCB practitioners, personnel such as PCB engineering, PCB electronic engineers, etc. use and learn.
1mil in mil
Line width/line pitch/plating thickness Common units: 1um (1 micron)=0.001 mm (0.001 mm)
1um=0.03937mil
1um=40uin (micro inches)
1um (1 micron)=0.001mm
1mil in mil=0.0254MM (Conversion reason: 1mil=1/1000inch=0.00254cm=0.0254mm)
As we all know, 4mil/4mil=0.1mm/0.1mm line width line spacing 1mil in mm=25.4um 1mil=1000uin mil, sometimes also known as English wire II (common unit of copper thickness in pcb board) 1OZ (ounce)=35UM (micrometer)=28.35g/square foot
1OZ (ounces)=28.35 grams, which is in English units
1OZ (oz)=28.35 grams per square foot=35 um micrometer H/H=18 um/18 um micrometer double-sided plate with both sides of 18um copper thickness Three relatively uncommon bit conversions:
1 foot=12 inches
1 inch inch=1000 mil
1ASD=1 ampere per square decimeter=10.76 amperes per square foot (1 square decimeter=10.76 square feet)
1AM=1 ampere minute=60 coulombs, mainly used for precious metal electroplating such as gold plating
1 square foot=9.29 square decimeters 1 gallon (English)=4.5 liters
1 gallon US=3.785 liters
1KHA=1000Ah
1 ampere hour=3600 coulombs
