Precision BGA Spheres Optimize Sphere Performance
Indium Corporation's manufactures solder spheres for PBGA, CBGA, TBGA, µBGA, and flip-chip applications. The solder spheres are made using a proprietary manufacturing process that provides consistently high sphericity and accurate diameters.
Indium Corporation can make almost any solder alloy sphere to suit customer needs. Standard alloys include both Pb-free and SnPb eutectic. Standard sphere diameters are commonly packaged in tape & reel and are listed below. We are constantly expanding and adapting our product offering to meet customer needs, so please contact us if you have a unique request.
We also offer two different standard diameter reels for tape & reel solder spheres:
|Reel Diameter||Pitch of Carrier Tape||Sphere Diameters||Maximum Spheres Per Reel|
Experience has shown us that consistent tape peel strength eliminates process start and stops and materials losses. Indium Corporation's manufacturing procedures and quality assurance eliminates these customer concerns.
Solder spheres are available in many alloys including industry standards:

In our continued investigation and quest to improve solder paste printing for fine-feature paste deposits, we also found that consistency (low standard deviation) favored the square apertures when comparing circular apertures to square apertures with radius corners (hereafter referred to only as square apertures).

Folks, Some years ago, a leading IC manufacturer decided that their R&D effort could benefit if analyzed for possible improvement – by hiring professionals from the arts (e.g. singers, actors, artists etc.) In this spirit, I am going not quite so far from electronics assembly, to ask one of Dartmouth’s premiere...
