Susan reason for the elctroless doing that is 1) - at times when u do a section and look closely - there is an inclusion in the deposit - whether from the bath or from the resin - matters not - 2 - if ur getting a spongy - amorphous copper deposit - it's really out of balance - would look into the stabilizer package when that is happening. but to tell uthe truth - haven't seen many spongy deposits - unless you are referring to blisters in the hole - then would look at the reducer. regards Richard Fudalewski Florida CirTech ############################################################## 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.
