Hi Joris, I've used 10's of Millions of these (and the AVX version - PBRC****) and never found this problem (I also worked for Murata back in the mists of time & never encountered it). Internally the part is thermally symmetrical, so the only thing

I have been soldering 0603 components on the bottom side using a glue and wave solder process for a long time. Bridging has not been a common problem. However, it is inherent on the design engineers to follow good manufacturability planning when la

| I'd like to find some technical papers on the reliability of reworked BGAs. If you know of any, please let me know. | | I have a concern about this because our current rework process does not apply solder paste to the pads prior to placing the pa

I'm trying a second time to post this very important message, to me, concerning Air-Vac's following creation. Does any own and use this stuff successfully to remove solder from 20 layer and up MLB's with .020" diameter holes? Also, is any of the adve

Hello guys , we just started first trials on PTH connectors mounted in SMD. Our first results show big deviation of solder filing in the hole and also a dramatic decreasing of mounting spped on pick & place equipement. 1 - Did someone uses proflow

We've been doing this for over 10 years using flux. We print a tacky flux first using an 0.002 or 0.003" thick stencil, then print paste using a thicker stencil with the underside half etched to keep it away from the flux. In our case, we can't jus

I have a PCB laminate that is 1 1/2 years old and showing signs of poor solderability. The NC flux I am using will not breakdown the oxides. During hand soldering the pads do not take solder. I am trying alternative fluxes and have seen an improve

we use a company that pays us for our left over solder paste in the pot. and for dross.

To resolve this issue, we use stencils with a step in the location of component with the solder charges.

When rushing to get a job done, it's easy to accidently remove solder mask from a nearby via when dressing BGA pads after removing the part. Just hit the via with some super glue [then say a small prayer] and push on. As an alternative, look here:
