Solder Joints Failure Under Low Strain-rate Cyclic Loading

Solder joint reliability has been a key issue for electronic assemblies and microelectronic packaging for many years. Many different factors can affect the solder joint reliability,such as pack .. read more

High Melting Lead-Free Mixed Biagx Solder Paste System

Although lead-free soldering has been main stream in the industry since 2006,with the replacement of eutectic SnPb system by the Sn/Ag/Cu system,the development of drop-in lead-free alternative .. read more

The Relationship between Backward Compatible Assembly and Microstructure on the Thermal Fatigue Reliability of an Extremely Large Ball Grid Array

Accelerated temperature cycling was used to evaluate the thermal fatigue reliability for the case of backward compatible assembly (mixed alloy,Pb-free BGA/SnPb paste) of a 3162 pin count,extrem .. read more

Mechanical Shock Test Performance of SAC105 (Sn-1.0Ag-0.5Cu) and Sn-3.5Ag,BGA Components with SAC305 Solder Paste on NiAu and OSP Board Surface...

Many BGA and CSP component suppliers have begun shipment of components with a variety of second generation lead-free solder ball alloys based on the improved mechanical shock resistance. Althou .. read more

Drop Test Performance of A Medium Complexity Lead-Free Board After Assembly and Rework

The mechanical behavior of printed circuit assemblies (PCA) at high strain rates is very important for the reliability of products used in harsh environments. The transition to Pb-free material .. read more

Rework Process Window and Microstructural Analysis for Lead-Free Mirrored Bga Design Points

Hot gas rework of BGAs with a mirrored BGA design configuration using SnAgCu based lead-free alloys is more challenging as compared to conventional SnPb techniques. Rework of BGAs using a conve .. read more

Solder Ball Attachment Assessment of Reballed Plastic Ball Grid Array Packages

This paper presents lead-free ball grid array (BGA) packages subjected to two ball removal and two ball attachment techniques. Solder attach strength is used as a metric to examine the reballin .. read more

Properties that are Important in Lead-Free Solders

The change to lead-free solders has forced the electronics industry to consider more than it ever has before what properties are important in a solder. When the tin-lead eutectic was the only s .. read more

The Effect of Ni on the Microstructure and Behaviour of the Sn-Cu Eutectic Lead-free Solder

While the Ni-stabilized Sn-0.7Cu alloy is now well established as a viable lead-free solder in large scale commercial printed circuit board assembly the effect of Ni is not yet fully understood .. read more

Perspectives on Repaired Lead-Free Solder Joints

The use of lead-free (LF) solders as a replacement for traditional tin-lead (SnPb) solders in military and high reliability applications has a number of technical challenges unique to the indus .. read more

Applicability of Bi-42Sn-1Ag Solder for Consumer Products

Eutectic Bi-42Sn solder is a low melting point alternative to lead-based solders,particularly for low cost,consumer electronics. In earlier work,the mechanical properties of this solder have be .. read more
