Effect Of Vacuum Reflow On Solder Joint Voiding In Bumped Components

Voids affect the thermal characteristics and mechanical properties of a solder joint, thereby affecting the reliability of the solder interconnect. The automotive sector in particular is requiring the mitigation of solder voids in various electronic control modules to the minimum possible level. Earlier research efforts performed to decrease ...

Void Reduction in Bottom Terminated Components Using Vacuum Assisted Reflow

Pockets of gas, or voids, trapped in the solder interface between discrete power management devices and circuit assemblies are, unfortunately, excellent insulators, or barriers to thermal conductivity. This resistance to heat flow reduces the electrical efficiency of these devices, reducing battery life and expected functional life ...

Key Advances in Void Reduction in the Reflow Process Using Multi-Stage Controlled Vacuum

This paper explores new advances in the reflow soldering process including vacuum technology and warpage mitigation systems. The first topic for discussion will be the implementation of a vacuum process directly in a conventional inline soldering system. The second topic presented is the mitigation of warpage on substrates or wafers.

The Effect Of Vacuum Reflow Processing On Solder Joint Voiding And Thermal Fatigue Reliability

A test program was developed to evaluate the effectiveness of vacuum reflow processing on solder joint voiding and subsequent thermal cycling performance. Area array package test vehicles were assembled using conventional reflow processing and a solder paste that generated substantial void content in the solder joints. Half of the population ...

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. :)
