Subject: [TN] Exposed copperI have a question concerning the subject matter of "exposed copper" on conductors and/or ground planes due to missing solder mask. I have reviewed the IPC-A-600 and SM-840 and have came to a conclusion on this. I want to hear from the experts, which includes all of you, the interpretation of this condition. I want to know if this is a defective condition or not, what makes it defective, or if it is acceptable; anything you all want to tell me. Thanks much.
