Hello, Can anyone recommend a supplier for alkaline ammonical etchant and replenisher? We wish to try an alternate source to our present supplier. Also, can we add ammonia (ammonium hydroxide) to the main etch tank and add the replenisher only to the subsequent chambers? Finally, what kind of transportation costs can we expect? Thank you, Dan Brandler. --------------------------------------------------------------------------------- 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 ---------------------------------------------------------------------------------
