2、information I found from various sources. 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 means it is down to the User to determine its accuracy.Designed This Program was designed by Phillip Restall and is in no way connected with Aculab plc. By （需设定） （需设定）
