Also how its related to a device to device connectivity, ie what is the width dimensions for a particular value of current Ex: 5 mils width for a 2 mAmps current. Let me know if there any link in case to understand these fundamentals regards Hariharan ------=_NextPart_002_000C_01C2CE12.66A815A0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META HTTP-EQUIV=3D"Content-Type" CONTENT=3D"text/html; = charset=3Diso-8859-1"> <TITLE>Blank</TITLE> <STYLE>BODY { COLOR: #000000; FONT-FAMILY: Arial, Helvetica; FONT-SIZE: 10pt; = MARGIN-LEFT: 25px; MARGIN-TOP: 25px } P.msoNormal { COLOR: #ffffcc; FONT-FAMILY: Helvetica, "Times New Roman"; FONT-SIZE: = 10pt; MARGIN-LEFT: 0px; MARGIN-TOP: 0px } LI.msoNormal { COLOR: #ffffcc; FONT-FAMILY: Helvetica, "Times New Roman"; FONT-SIZE: = 10pt; MARGIN-LEFT: 0px; MARGIN-TOP: 0px } </STYLE> <META content=3D"MSHTML 5.00.3315.2870" name=3DGENERATOR></HEAD> <BODY background=3Dcid:362094512@06022003-224e=20 style=3D"COLOR: #000000; FONT-FAMILY: Arial"> <DIV> </DIV><BR> <P><SPAN class=3D362094512-06022003>Hi,</SPAN></P> <P><SPAN class=3D362094512-06022003>I'd like to know about the = calculations for=20 Trace width on a PCB (FR-4).
