Mar 18, 2008 | Atilim Demirtas, Vestel Digital

This paper examines the construction of a notebook mainboard with more than 2000 components and no wave soldering required.

However, state of the art technology does not help if the process parameters are not set carefully. Can all complex BGAs, THTs and even screws be soldered on a single stencil? What will help us overcome bridging, insufficient solder and thombstoning issues? This paper will demonstrate the placement of all odd shape components using pin-in-paste stencil design and full completion of the motherboard after two reflow cycles....
