Hi, This is the first time I have used the Technet forum . I'm hopeful that there is some information out there to help me with the following questions. Thanks in advance for your help!!!! 1) standards for polarity identification of axial-leaded and chip style diodes on the component body and how does this correlate to '+' and/or square land on the board . 2) square lands used to indicate polarity as in pin1 or 'positive' ; is this an industry standard? Does a silkscreen '+' have precedence over the square land as a Pin1 indicator? I look forward to responses from the forum! Thank you, Gail Herman LPAT Process Technician 433(293)-6395 pager 487-4964 [log in to unmask] ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
