We have a PARMI SigmaX SPI (Solder Paste Inspection) machine, right now I'm trying to understand about parameters of the machine. I know minimus, Maximus, and warning values need to be defined. Height value understands that can be defined by the thic

Good luck in your conquest. I have been struggling with the same issues for some time now. I have made the following conclusions. First, it is nearly impossible to establish parameters in SMT to perform X-Bar and R charts. Electronics is not as cl

Also note , KY is SPI company and there 3D technology is just SPI tweaked to do 3D AOI, same can be said of Mirtec but bit better than KY. Generally they are slow in capture and this is why in EU and say high volume sites 3D has not penetrated much.

Cpk is sometimes referred to as the voice of the process because it is measuring how tight your process is in relation to the specification limits. A Cpk of 1 means that you are running a 3 sigma process (plus or minus 3 sigma). This means that you

SPM is superior. SPM has larger print area, up to 20� x 19", vs. 17.7� x 15.7� for the UltraPrint 100. UP100 is microprocessor controlled while the SPM has a PC. The SPM cameras can be positioned more rapidly and with greater accuracy than UP100's.

Mathematically, measure the component offsets from nominal then calculate the average and the SD of the offsets in x and y. You can then use the following equation to calculate the CpK: CpK = (Process Width - Abs(Average offset)) / (3 * SD offset)

Running the PAM board is a great tool. Using another machine to get you CPK is very inportant. We use the DT651 which does everything the PAM rom card does plus it gives a CP and CPK value. You can also use it to verify feeders in the X and Y. SMT re
