Hillel, Referring to IPC-6012, Par. 3.6.2.3. "Multiple voids between two adjacent plated though holes in the same plane shall not have voids that same plane shall not have combined length which exceeds those limits." For class 2 and 3, this is 0.003 inch. See also Par. 3.6.2.4 that states the same for cracks. I am not sure that you can designate it resin-starved when you view resin-starvation in a vertical microsection. The microsection may show up as multiple tiny voids, a kind of foam, a cracking or nothing at all. Most often this type of feature is seen in visual exanination, and IPC-A-600 has some good pictures of this. IPC-6012 says to go to IPC-A-600 for some of those defect visually seen in the board, such as crazing, measling etc. Phil Hinton ############################################################## TechNet Mail List 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 web site (http://www.ipc.org/html/forum.htm) for additional information.
