I am also inquiring about spacing requirements that meet UL approval. Please also send me any information that you find. Thanks, Mike ______________________________ Reply Separator _________________________________ Subject: UL approval Author: [log in to unmask] at SMTPLINK-Micros Date: 4/8/96 11:22 PM I am looking for information on the spacing requirements necessary to meet UL approval. Can anyone give me a reference on where to find these specs? I'm also looking for information on the spacing requirements necessary for auto-insertion. I know resistors have to be spaced 120-125 mils apart and radial caps cannot be auto-inserted. What about IC's and other parts? Are the spacings different for different pick-and-place machines? What guidelines do you go by? Thanx for your help.
