Process & Preparation in using Lead Free Solder | 14 August, 2004

I'm currently working in a SMT factory in China. I'd like to know what preparation that I would need to change from leaded to lead free soldering. 1.Starting with the PCB production, things that I need to concern about are solder mask, Cu protection, OSP, gold plating. 2. Type of parts & paste used for SMT process. 3. Type of materials used for Wave soldering (Dip soldering). 4. Type of reflow system.

It would be really appreciate if someone can give me a clear insight of what I need to know and prepare, before going ahead with the change.

Many thanks, Dave

I think you are going to find it very difficult for people to hand over the formula for a sucessful LF process.

Sources are: * Most major solder suppliers have information on their sites. Some, like AIM, offer seminars. * Check nemi, leadfree, and UK's Department of Trade and Industry sites * IPC and SMTA offer seminars and webcasts [IPC is sponsoring a webcast by Kay Numo on August 25, 2004]
