Ioan,

 In past years I spent some time looking at "Laser Soldering" and I had some
nice conversation with Beam Works folks at APEX shows. 

 Basically, in a nut shell, using a laser does not provide a lot more than
slightly focused IR.

 If I have it wrong I hope someone can let me know!

Thanks,
Bob Kondner

Subject: [TN] Laser soldering of BGA

Dear Technos,

 

Any insights on BGA laser soldering? It is for soldering a 15x15 mm BGA onto
a flex PCB. The flex is backed by a rigid substrate in the BGA zone, but due
to mechanical constraints this substrate cannot be thicker than 0.012". 

 

Oh yes, lead-free.

 

Thanks,
