Now, the burden is on the designer to carefully study a board design and to devise certain fan-out strategies that don't adversely affect fabrication requirements. ... 0.4-mm pitch BGA and sidestepping major board fabrication issues. The BGA ...
Get Price2012-9-10u2002·u2002Ultra-fine pitch devices pose new PCB design issues. Ball-grid array (BGA) packages come in a variety of pitches and sizes. As device complexity increases and OEMs continue their drive toward smaller components, ball pitches of 0.5 mm and lower are becoming more popular. Pitch is defined as the space between the center of one BGA ball to the ...

This not only reduces the overall mounted height of the package (a plus of slim portable electronic products) but has also been thought to improve the board level reliability for cyclic bending and drop. It is also expected that the ...
