Hi I completely agree with you. Also, the Dry Solder paste can be used in wireless repair operations such as the repair of smart phones, tablets, laptops and other handheld devices. The lead-free solder paste can be squeegeed through the apertures of

In my experience there is no need for wet wiping stencils. We run 0201'and micro BGA's daily with no issues. If you are having paste release issues, I would be looking at other things. Aperture area aspect ratio, aperture design, land design, sold

Hi Dave, Thank you. I have been through IPC 7525A. But our boards bit more complicated and quality requirements are very stringent. 7525A doesn't help for much extent. Any other you have gone through and found to be very good to understand and lear

We usually replace stencil when we start to get problems with the solder paste printing i.e. uneven solder paste deposit etc. Until then it doesn't matter how many years ago it's manufactured, but how many prints it passes and if the operators didn't
