| We are getting into a lot of double sided boards offlate. Our customer is loading a lot of RNETS, Diodes ( MINLS, SOT23s and other 2 leaded diodes ). We are processing it through a traditional glue process and wave soldering the SMT parts along wit

Hi there, Has anyone got any 'positive' thoughts and advice on wavesoldering mini-melf components on solder side of PCB. So far results have been crap, in some cases both pads completely skipped. Is this type of problem generic with mini-melfs or mor

We have been wave soldering mini-melfs for many years. Main problem for us has been excess and bridging joints but few skips. To overcome our problem we provide a minimum of 0.5mm clearance around each component, not great use of real-estate but prov

Steve, I am not aware of any standards so to speak. But IPC 782 and 770 have some useful info regarding mounting and pad geometries for wave etc... Since I do not know what type of components you will be wave soldering I will just give you some

Larry, SOTs are a wonderful thing to try and wave solder! They are about as nice as Tant caps. I have found that shadowing is usually the biggest problem assuming that the other wave parameters are good, in your case it seems that they are. Couple

Hello All, Using IR will mean that there is no minimum distance to the adjacent components as there is not hot air flow. If components are heat sensitive around the BGA you can also tape them off with a reflective tape. The IR heat will bounce strai

Hi! From your post, it seem like the wave did not really touch the component. You probably need to get the both wave height correct and that it hits the component.It is normal for solder to come through the PCB when using chip wave. The through-hole

Thank you Steve for your input it was very usefull. I think I skipped a few pertinant details on my initial message though, the component which we found the flux contamination on was on the top side of the board, I was curious if the flux could come

Dave, to answer your questions, point-by-point: � Just out of curiosity, how are second side, skippy components oriented on the board with respect to the wave? The SMD's are all oriented in the "correct" direction with respect to wave direction(i

My company just purchased a Vecta (E-vert) wave soldering machine. Bridging has become a serious issue, both on SMT components and thru hole. We are currently seeing about 500 ppm. The products that are being run now were run previously on our old
