cold joint on 1 lead of IC

Electronics Forum | Thu Feb 08 08:15:28 EST 2007 | tjcrume

I have received 10 customer returns for a cold solder joint on 1 lead of a 36 pin IC. Everytime it is on the #18 pin. The process is reflow and I can't figure out why the one leg is cold and the other legs look OK.

A little late to the party here, sorry... Has the joint been verified as a cold solder joint? That is, visually confirmed that it looks like cold solder, and, perhaps, xrayed to confirm the solder status? X-raying may sound a bit extreme, but you'

What is the working principle of I.C.T Lyra Reflow Oven

Industry News | 2022-11-11 07:33:41.0

Lyra Reflow Oven is a soft soldering that realizes the mechanical and electrical connection between the solder ends of surface mount components or the pins and the printed board pads by remelting the solder paste pre-distributed on the printed board pads.

Low Cycle Fatigue Behaviour of Multi-joint Sample in Mechanical Testing

Technical Library | 2013-03-21 21:24:49.0

This paper explores the behaviour of a copper test vehicle with multiple reflowed solder joints, which has direct relevance to ball grid arrays (BGA) and high density interconnect structures. The paper explores the relative stress conditions on the distributed joints and the sensitivity to ball joint shape... First published in the 2012 IPC APEX EXPO technical conference proceedings

Analysis of the Mechanical Behavior, Microstructure, and Reliability of Mixed Formulation Solder Joints

Technical Library | 2023-09-26 19:14:44.0

The transition from tin-lead to lead free soldering in the electronics manufacturing industry has been in progress for the past 10 years. In the interim period before lead free assemblies are uniformly accepted, mixed formulation solder joints are becoming commonplace in electronic assemblies. For example, area array components (BGA/CSP) are frequently available only with lead free Sn-Ag-Cu (SAC) solder balls. Such parts are often assembled to printed circuit boards using traditional 63Sn-37Pb solder paste. The resulting solder joints contain unusual quaternary alloys of Sn, Ag, Cu, and Pb. In addition, the alloy composition can vary across the solder joint based on the paste to ball solder volumes and the reflow profile utilized. The mechanical and physical properties of such Sn-Ag-Cu-Pb alloys have not been explored extensively in the literature. In addition, the reliability of mixed formulation solder joints is poorly understood.
