Reliability and IMC Layer Evolution of Homogenous Lead-Free Solder Joints During Thermal Cycling

Many leading solder paste manufacturers are currently developing solder alloys for high reliability applications. These solder alloys are doped with elements such as bismuth (Bi), indium (In .. read more

Pb-free Solder Joint Reliability in a Mildly Accelerated Test Condition

Two different temperature cycling profiles were used to compare the thermal fatigue reliability of Pb free and SnPb solder joints in 16 different,high strain surface mount (SMT) packages. In so .. read more

The Effects of Non-filled Microvia in Pad on Pb-free Solder Joint Reliability of BGA and QFN Packages in Accelerated Thermal...

The High Density Packaging Users Group (HDPUG) Consortium has completed an experiment to investigate the effect of non-filled microvias in SMT solder joint pads and the associated solder voids .. read more

Low-Silver BGA Assembly Phase II – Reliability Assessment Seventh Report: Mixed Metallurgy Solder Joint Thermal Cycling Results

Some ball grid array suppliers are migrating their sphere alloys from SAC305 (3% Ag) or SAC405 (4% Ag) to alloys with lower silver contents and often with “micro alloying” additions. There are .. read more

Achieving High Reliability Low Cost Lead-Free SAC Solder Joints Via Mn Or Ce Doping

In this study,the reliabilities of low Ag SAC alloys doped with Mn or Ce (SACM or SACC) were evaluated under JEDEC drop,dynamic bending,thermal cycling,and cyclic bending test conditions agains .. read more

Low-Silver BGA Assembly Phase II – Reliability Assessment Fifth Report: Preliminary Thermal Cycling Results

Some ball grid array suppliers are migrating their sphere alloys from SAC305 (3% Ag) or SAC405 (4% Ag) to alloys with lower silver contents. There are numerous perceived reliability benefits to .. read more

Assembly and Reliability Investigation of Package on Package

This paper discusses the results of several independent experiments designed to address the many aspects of successful PoP integration. Assembly through the use of in-line stacking and pre-stac .. read more

FEA Study of Solder Hole Fill Impact on the Reliability of PTH Solder Joints

This paper is focused on the impact of solder hole fill on the reliability of the plated-through-hole (PTH) solder joints with different board thicknesses. Finite element analysis (FEA) is empl .. read more

Comparison of Thermal Fatigue Performance of SAC105 (Sn-1.0Ag-0.5Cu),Sn- 3.5Ag,and SAC305 (Sn-3.0Ag-0.5Cu) BGA Components with SAC305 Solder Paste

Many BGA and CSP component suppliers have begun shipment of components with a variety of “second generation” Pb-free solder ball alloys. Much of the motivation for the alloy changes has been to .. read more

Long Term Reliability Analysis of Lead Free and Halogen Free Electronic Assemblies

The New England Lead Free Consortium,composed of many companies in the electronic supply chain in the regional area and chaired by the author; has embarked on an extensive long term reliability .. read more

Solder Joint Reliability of Pb-free Sn-Ag-Cu Ball Grid Array (BGA) Components in Sn-Pb Assembly Process

For companies that choose to take the Pb-free exemption under the European Union’s RoHS Directive and continue to manufacture tin-lead (Sn-Pb) electronic products,there is a growing concern abo .. read more
