Manish, I've seen similar phenomenon when processing CSPs on our cards. In our case, we were placing the components over the opening to in-pad blind vias. Due to poor drilling and plating processes by our board suppliers, volatiles were outgassing

Hi Everybody | | Is anyone aware of the possible causes that may lead to voids in the solder bumps after assembly. We assembled some dice on thin substrates and after assembly, void formation in the solder bumps were observed. | We have alread

SHENMAO Bumping Solder Paste PF608-PI-21 (Sn/Ag4.0/Cu0.5/x) and PF606-P-BS1 (Sn/Ag3.0/Cu0.5/x) aim to decrease voids in wafer bumping process. SHENMAO MICRO MATERIAL INSTITUTE applications engineers focused on developing the Bumping Solder Paste Formula with excellent stencil printing transfer rate and the lowest Void to optimize manufacturing process performance. The world’s largest IC Packaging and Test Service OSAT utilize SHENMAO Bumping Solder Paste in production.

Programs have been developed to predict the expected yield of flip chip assemblies, based on substrate design and the statistics of actual manufactured boards, as well as placement machine accuracy, variations in bump sizes, and possible substrate warpage. These predictions and the trends they reveal can be used to direct changes in design so that defect levels will fall below the acceptable limits. Shapes of joints are calculated analytically, or when this is not possible, numerically by means of a public domain program called Surface Evolver. The method is illustrated with an example involving the substrate for a flip chip BGA.

Bare die mounting on multi-device substrates has been in use in the microelectronics industry since the 1960s. The aerospace industry’s hybrid modules and IBM’s Solid Logic Technology were early implementations that were developed in the 1960’s. The technologies progressed on a steady level until the mid 1990’s when, with the advent of BGA packaging and chip scale packages, the microelectronics industry started a wholesale move to area array packaging. This paper outlines the challenges for both traditional wire-bond die attached to a printed wiring board (pwb), to the more recent applications of bumped die attached to a high performance substrate.
