John: Secure the capacitors that you removed from the machine ... * Removed capacitors have a problem * New replacement capacitors don't have a problem Find help to determine the difference between the two reels of parts

Yes I have a KIC and have checked the profile often. I just changed the reel of the parts that are causing problems and it went away. Now what am I suppose to say? I have made an NCMR for the parts but I'm sure they would work in an environment of

Here’s what we seem to know: * There’s a problem with voiding in the solder connections of SMT capacitors * A void is an open area caused by air or process fluid that is trapped within a solder connection * Voids are an allowable condition as long as

Volume of paste = 2X volume of the hole Questions are: * Why does your customer want the hole filled with solder? * Would materials other than solder be acceptable? * We assume 0.020" is drill size. What is the finished size of the hole? * What is t

Hi all, I would like to have some information regarding the paste in holes process.We are the Backplane manufacturing and dealing with lots of thick PCB and would like to change the processes from wave to paste in hole.Any feed back of info or exper

No I was actually thinking more on the lines of this. http://pcdandf.com/cms/content/view/3845/95/ I think if you try and put solder in the hole you will not have a flat or well filled hole in the end.

Wayne, Earl, I wish there was some way we could toss our wave solder machine forever! Unfortunately, we haven't found a way yet to do paste-in-hole reflow for large numbers of thru-hole axial and radial components, which we insert on Universal machi
