Hello, We are having quality issues with our current stencil manufacture for our SMT line. Could you give me some names of companies that you are satisfied with that are located in the US? Thank you in advance for your replies. Regards, Corey

I've used BlueRing stencils (formerly Metal Etching Technology) for over 10 years and have been happy. Helpful technical support with design too. Disclaimer: I have no affiliation with them.

I also use Bluering formerly ASI/MET. We have been using Vectorguard stencils with them for a number of years.

I don't think there's really any industry standard tolerance setting or value. It's safe to open up the tolerances pretty wide as long as your placement accuracy doesn't suffer.

I require component engineering to spec in multi vendor parts as long as the following exists 1.Mechanical +/- 15% 2. Same orientation in pocket 3. Same pocket dimensions I have to beat the engineering a few times per year but I think they have the

Hi experts, I have some stencils in a bad state. Some of the marks belongs to squegee operation. I wonder if it is possible to measure the pressure that is being applied, as we can set the pressure, but we don't know if that value is real and calib

If you have pressure sensors in there(most contemporary machines have), value is probably right. It doesn't mean though that the value is correct(see the upper post)

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.

Can you send me a screenshot to see how it looks or a spreadsheet of the data? Do you have to modify anything on your own? Can you do it for some selected components/apertures or it has to be on the whole PCB? Any further info will be appreciated.

Thanks for your fast reply. As I think I want to use a stylus with the lighrroom, not only to draw, but also to make compatible with my lenovo ideapad stylus.
