The process is setup to check the first 3 or 5 parts off a reel, I suppose you could check every part but the time would be unreasonable. The cracks in our experience do not become apparent until the reflow process when heat is applied exposing the material to stresses. We are a MY12 user but this was not a feature of the equipment as explained to us. Dave C. CSI -----Original Message----- From: Tom Parkinson [mailto:[log in to unmask]] Sent: Wednesday, July 07, 2004 12:44 PM To: [log in to unmask] Subject: [TN] Mydata Info One of our customers has said their other CM uses a Mydata SMT pick and place system that has the 'on-the-fly' testing. From what our customer says, this testing will catch all marginal passive parts, including any SMT caps that may have very small cracks. Anyone have experience with this 'on-the-fly' testing option?
