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 voids involved varying the reflow profile, paste deposit, paste alloy composition, stencil aperture, and thickness. Due to the various advantages ...

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 time of electronic assemblies. There is also a corresponding increase in current density (as the area for current conduction is reduced) that generates additional heat, further leading to performance degradation.

Help TQFP welding problem -- We are currently producing a project that brings a TQFP64. But some boards do not solder the component well with its ideal fillet, some are well soldered when they come out of the reflow oven, but some are not. Can the pins be sulphated? How can we check and make sure they are sulfated? I mount the curve we currently use for alpha om5300 type 4 paste

Array drawing software -- Do you have a software that you can use to create dimensional array drawing for PCB using gerbers or gerber input. If not, do you have software that can open board house gerbers and create a dimensional pdf drawing? Thank you!
