Hello Guys, I would like to know any informations regarding Solder ball on BGA oxidation. Our BGAs were heavily oxidized (Solder balls). Anybody knows how to remove the oxides and prevent it from re-occurring again? The solder ball we used is 95/5 PbSn alloy. Thanks and God Bless --------------------------------------------------------------------------------- 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 ---------------------------------------------------------------------------------
