I guess we should differentiate between machine calibration, process reliability measurements and process capability study. For the machine calibration you use the machines own optical cameras, but for cpk or standard deviation you measure the place

Hi All, Could you share for me inspection spec that you set up for SPI machine ? Which standard you base that? IPC or something like that. So far, my factory set up as below: Area , volume , high are: lower limit is 60%, upper limit 160% for 0201 ch

Hi,Dear We are specialized in producing SPI and AOI Chinese manufacturers, are you interested to talk about it?

Thank for your sharing. I am also trying find out the best parameter for our product.

Hello sir, Limits in SPI can vary a lot, also depending on finishing of the pcb. For example 170% volume on an IC (assuming is fine pitch) can be okay for ENIG, but very bad if HASL. For are I would recommend that you use either 50-130, or 60-135 max

Hello fellow experts! Does anyone have a SPI machine that can calculate Cpk for the solder paste height across the PCB or for selected locations? Any feedback will be appreciated.

Parmi SPI does CPK

Instead of you spend money on AOI,my recomendation will be to install SPI machine ( solder paste inspection machine)since most of your defect are solderability issues.AOI only will ensure no escapee to backend/human escapee but SPI will help to to en

Does anyone have a suggestion on where to get a relatively inexpensive CMM for measuring my SMT accuracy? Even an XY table with a digital position display would be pretty handy to have. I use mostly Panasonic equipment at my current company, and I
