I would think the panel would warp like crazy when it hit the wave. The center will bow down into the wave - you'll probably get bridges in the middle and solder skips at the edges of the panel. I've been at places where they tried wave soldering with just using titantium stiffeners on 0.040 " multilayers but it didn't work. They had to make up pallets with internal webs and spring loaded board supports to a top rack of the pallet to support the center of the panel.

Subject: EXTERNAL: [TN] Wave soldering of 0.031" thick PCBs

Dear Technos,

 

What is your experience with wave soldering of 0.031" thick boards? Is it possible to pass them without wave pallets, with leading and trailing stiffeners only?

 

I'm still trying to figure out the panel, guess it will be something like 7"x11".

 

Thanks,
