Hi Dave, Would this be different from IPC-610-D. I am not sure.

I am looking for the same. IPC 610D does mention about the solder fill based on the class (A,B,C). But, there is no exhaustive study that I have come across. Please let me know if you find any. KT

Part is most likely a QFN package. IPC-610-D has standards on solder quality for this new type of package.

Hi Pat According IPC-610D voids biger 25% are considered defects. You need verify you Pre Heat and try to reduce the ramp. Its very importante verify if the BGA`s are avoid hummity. Erli

Whether there's a fillet or not depends on the component type. Most have a fillet but some, such as QFN's, don't necessarily have one. Have a look at IPC-610D Workmanship Standards to understand when you should expect one and when you shouldn't. T

For visual inspection table 1-2 seems to be in order here. If you can not see the bottom using 1.8 and table 1-2, it clearly would be a defect and rework would be the only option Well, my thoughts anyway, wonder if someone has other thoughts on thi

Switch to SN100C (no pun intended). I cant help with the SAC 305 issues but we should have a wave with SN100 running very soon. I will let you all know how that goes. Please report back on the x-sectioning and share the results. I have heard some v

Greetings Tried to search past threads without an answer. I have a resistor that just fits the between pads. Some of the resisitor were installed without the termnation sitting on the pad and are infact sitting on solder a good .020 to .025 above th

CW, The good news is that you are not trying to use SAC paste with SnPb balls for that would be a void generator due to the ball being liquidous while the SAC paste is still in a flux cleaning stage. Two points to consider: One, voids are not an i

Hello All, Can somebody direct me to a facility or school or even a business that can offer an x-ray course for Class 3 electronic circuit board population interpretation, as in BGA ball acceptance, connector solderability fill acceptance etc.? Some
