Is it possible to Process Top & Bottom side PCBA simultaneously in One SMT Line. (An atrticle by Jagadeesh Rajagopalan, SMT Process consultant). Pls check this and suggest me whether it is possible? & What should be the Lead free Reflow Profile? http://www.indyarocks.com/blogs/blog_visiterview_main.php?id=48986#blog48986

We have successfully implemented this dual Process You can use any printer that supports Board width 500mm. SMT Dual Process Maximum PCB Width should be (500-20 / 2 ) = 240mm Max (PCB width )Printer support = 500mm Top width + Bottom width = 2 In between Distance = 20 mm

Optimize the topside Reflow Profile for the SMT Dual Process

What is the PCB width? Why can't you try screen printing in a pallet keeping TOp & Bot same time as mentioned in the article.? Then you can built TOP & BOT by following Line confg Loader -->Printer(DEK265)-->Gule -->SPI -->Mounting(NXT)-->AOI -->Reflow -->

If you have an even multiple of boards in a panel, then your layout can be altered to have 1 top 1 bottom in the x layout so that when you flip the panel the same layout is on the opposite side therefore requiring just one program.
