0.20计算所需过孔最小数目

4.005转换

mil 密耳

39.37=1公英制换算微米60= 1.64铜皮厚度,见上图(当微米数是36.5时,Oz=1.00)

Please Note

最大温升

需要流过的电流(A )

最少需要过孔的数目 =毫米Oz By The via calculator simply converts the drill size into its Circumference And assumes this behaves the same as a trace Due to a lack of Data I cannot confirm the accuracy of this calculator (use as rough guide only).

This Program was designed by Phillip Restall and is in no way connected with Aculab plc.

This means it is down to the User to determine its accuracy.

过孔电流计算器 V2.0

每个过孔最大电流=0.996

Designed I have created the Via Calculator on information I found from various sources.
