Hi Ya'll!! It's picture time again! Got some boards in at incoming inspection that are really weird looking Go to: http://www.driveway.com/share?sid=e25a88c4.8e904&name=Pictures Look at Pits.jpg and Pits2.jpg...very, very strange! Never have seen something like this before...and it's only on the backside of the board? What could cause this? Looking in the IPC-A-600F, it only talks about reductions in conductor width of more than 20% (for class-2), but doesn't talk about reductions in thickness by pits such as these...it's hard to tell if they've gone all the way through the trace because the pits are filled with solder mask and you can't see all the way down to the bottom of the pits. Common sense tells me that these boards are rejectable...am I right? -Steve Gregory- --------------------------------------------------------------------------------- TechNet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF TECHNET Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
