YES to the first question in some points of the board. Bulky, to the second question when it is not in short. What you say about the PAD height, helped me to understand why the SPI shows weird values for other measurements. I am currently doing test

You demonstrate it and record it by the report. The report contains the check off items that you defined in the protocol along with supporting data from the testing you did. This usually involves part numbers,data points, and photos. The report shou

There are plenty of paste chemistries now that can be stored at room temp for far longer than 2 weeks. You should not return a paste to the fridge once it has been opened. If a tub of paste came out of the fridge mistakenly I see no reason to why it

Have you checked the temperature profile at the balls? Just because a recipe works "fine most of the time" does not mean it is optimum. Do you have a machine that can measure co-planarity? If I get time I plan on using the MPA to look at co-plana

If you have concluded that it is not a file storage problem you may wish to consider - When setting up a job the camera can move to virtually any position. This does not mean that the actuators on the stencil or board have enough travel to align the

My first concern would be the choice of solder paste you have. There are better chemistries out there that far exceed the capabilities of the 609 2. Yes, the part will partially float on the solder (assuming plastic qfp). Cross sectioning would sho
