Hi, Joyce, I am talking from an avionics standpoint. Minor measling is acceptable, but if there are any concerns about further delamination from the measles, they can be 'lanced' and injected with resin to bond them.

No. The measling looks quite minor and doesn't come close to other traces or pads. Unless I'm mis-judging the scale of the picture, the affected area isn't carrying high power either, so I don't see that there's a problem. Pete Duncan "Stephen R.

Sent by: TechNet <[log in to unmask] ORG> 06/05/01 02:58 AM Please respond to "TechNet E-Mail Forum."; Please respond to SteveZeva Hi ya'll! I took a few days off last week, and came back to be confronted with some boards that have been measled from rework... Go to: http://stevezeva.homestead.com/index.html to take a peek. The boards are polyimide, and it obviously appears that there was too much heat used when they were reworked...also they may have not been baked prior to the rework...I was told that they were, but you know how that goes. I know what the -610 says about it, it says it's acceptable as long as the assembly performs as specified. There isn't any burns or anything around any of the barrels, just the measles...and it's only on one 14-pin DIP location. Would any of you have any REAL hesitation about accepting this assembly? Thanks! -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 To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives 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 ------------------------------------------------------------------------ --------- --------------------------------------------------------------------------------- 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 To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives 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 --------------------------------------------------------------------------------- --------------------------------------------------------------------------------- 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 To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives 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 ---------------------------------------------------------------------------------
