Folks, I am an NPI Engineer at Artesyn technologies and I am new to the Surface Mount Technology. Can anyone shed some light on the differences between HASL and OSP. We are currently using HASL but are looking at migrating to OSP. What are the pros and cons of one over the other? What sort of processing issues do we see with OSP on SMT lines? Any help appreciated Cormac MacMahon --------------------------------------------------------------------------------- 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 ---------------------------------------------------------------------------------
