The Effect of Pb Mixing Levels on Solder Joint Reliability and Failure Mode of Backward Compatible, High Density Ball Grid Array Assemblies

Regardless of the accelerating trend for design and conversion to Pb-free manufacturing, many high reliability electronic equipment producers continue to manufacture and support tin-lead (SnPb) electronic products. Certain high reliability electronic products from the telecommunication, military, and medical sectors ...

Mixed Metals Impact on Reliability

With the adoption of RoHS and implementation of Lead Free solders a major concern is how this will impact reliability. Both commercial and military hardware are impacted by this change even though military hardware is considered exempt from the requirements of RoHS. As the supply chain has moved to the new lead free alloys both ...

Microstructure and Intermetallic Formation in SnAgCu BGA Components Attached With SnPb Solder Under Isothermal Aging

The global transition to lead-free (Pb-free) electronics has led component and equipment manufacturers to transform their tin-lead (SnPb) processes to Pb-free. At the same time, Pb-free legislation has granted exemptions for some products whose applications require high long-term reliability. However, due to a reduction in ...

Lead-Free and Mixed Assembly Solder Joint Reliability Trends

This paper presents a quantitative analysis of solder joint reliability data for lead-free Sn-Ag-Cu (SAC) and mixed assembly (SnPb + SAC) circuit boards based on an extensive, but non-exhaustive, collection of thermal cycling test results. The assembled database covers life test results under multiple test conditions and for a variety of ...

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

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 ...

Nordson FX 940 Ultra Nytvision bottom camera -- Has anyone been able to get the bottom camera option to work on Nordson FX 940 Ultra Nytvision? We tried three years ago, but they didn't have the software working yet. And their tech support wasn't sure how to get it working. Nordson is discontinuing the FX 940 and we would like to try the extra camera for barcode traceability. But we aren't going to buy from them anymore unless we know it works before purchase.

RJ45 connector selective soldering -- Hello professionals! I am quite new to selective soldering and i have been trying to get rid of solder bridges when soldering RJ45 connector. Seems like i got to point where 1/3 of soldered connectors doesn't have any bridges but other 2/3 have. Our company has Ersa Versaflow 3 selective soldering system. I have now tried with different size of nozzles, from small nozzle to big 18/20 nozzle (only like dipping whole connector at once) but seems like i cannot get better results. I have also tried different soldering times and preheating temperatures. I have also added flux etc. But seems like nothing helps... What to try next? Does anyone here have solved problem like that and could have some parameters what to try to get rid of solder bridges? Thank you. :)
