Why would anyone think that 100% touch up would be effective? In my experience touch up is likely to cause more problems than it solves - if you must do it and the application is that critical then I would say go automatic as you will have direct control of soldering parameters Neil -----Original Message----- From: Becerra Alejandro [mailto:[log in to unmask]] Sent: 05 December 2001 02:19 Subject: Manual Soldering vs. Automatic Soldering Hello to All, One product request a 100% touch up in several joints because of safety. We are considering doing this process by manual soldering or using automatic soldering (robot). What are the advantage and disadvantage of both procedures? Where can I find a comparison between them? Is there any reliability issue in using manual soldering? Any help will be greatly appreciated Alejandro Becerra _____________________________________________________________________ This message has been checked for all known viruses by Star Internet delivered through the MessageLabs Virus Scanning Service.
