Flatness measurement of electronic parts and assemblies, or PCB’s, has become increasingly critical as geometries become smaller: finer pitches, smaller solder ball volumes, thinner substrates, etc. Additionally, processing temperatures vary and can pla

AMTECH’s BGA solder spheres are manufactured from virgin materials to meet or exceed the requirements of building or repairing BGA packages. AMTECH BGA solder spheres also exceed both the IPC and MIL standards for purity levels and size tolerances. N
Bob Willis "How to Do It" video clip explains how to test BGA or Area Array Packages for solderability. The reason this is difficult to do by other means is the solder terminations would be displaced during solder contact. A simple test like this als

The head-in-pillow defect has become a relatively common failure mode in the industry since the implementation of Pb-free technologies, generating much concern. A head-in-pillow defect is the incomplete wetting of the entire solder joint of a Ball-Grid Array (BGA), Chip-Scale Package (CSP), or even a Package-On-Package (PoP) and is characterized as a process anomaly, where the solder paste and BGA ball both reflow but do not coalesce. When looking at a cross-section, it actually looks like a head has pressed into a soft pillow. There are two main sources of head-in-pillow defects: poor wetting and PWB or package warpage. Poor wetting can result from a variety of sources, such as solder ball oxidation, an inappropriate thermal reflow profile or poor fluxing action. This paper addresses the three sources or contributing issues (supply, process & material) of the head-in-pillow defects. It will thoroughly review these three issues and how they relate to result in head-in pillow defects. In addition, a head-in-pillow elimination plan will be presented with real life examples will be to illustrate these head-in-pillow solutions.

YINCAE has successfully developed a new No Clean Flux product -NC 256 with zero flux residue, excellent soldering wetting and eliminates the cleaning process. NC 256 has been designed not only for wafer ball bumping and other ball bumping such as CSP, BGA, Flip chip and PoP (package on package), particularly for lead free applications, but also for flip chip, CSP, BGA and other advanced components attachment to eliminate cleaning process.
