The weave of the anode bag is either too tight or has become plugged. Interior solution continues to build in CuSO4 concentration due to anode disolution until the interior solution becomes super saturated and crystallization is inevitable. Either clean andode bags or reduce the nap and weave in future anode bags. ################################################################ TechNet E-Mail Forum 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://jefry.ipc.org/forum.htm) for additional information.
