I'm not sure why anyone would pay extra for FG (fine grain) stencils. I've run studies comparing traditional YAG laser, fiber laser, and E-form stencils with regular stainless, FG, and nickel foils. YAG is the worse and should only be used for pret

Hello, I have a problem with settings vision for LED (similar to this one: https://www.lumex.com/news/SML-LXIL0603-narrow-beam.html) on JUKI KE3020. The LED is mounted on the side. At the beginning I would like to say that laser recognition is impos

Hi, I work with Omron AOI for almost 5 years. Sorry for the late reply, but I visit this site very seldom Basically Omron are considered as the best in solder joint inspection because it used patented 3 colour highlight principle and in 99% the missi

Hello gregp, IPC released 9850 on October 22, 2002 after the industry came together to standardize a method to determine placement capability as it relates to placement speed. As I'm sure you are aware, the standard gives placement machine manufactur

I have recently completed a HUGE screen-printing DOE. I used Taguchi methodology and man I got good results! Here is what I learned for what it's worth: (p.s. to the MPM apps guy I sent a copy to Tim Gillis, Lou Fuda, etc...) EFab vs. Laser: EFab

You are correct about KY having the lions share of 3D AOI in the industry. They were 2-3 years ahead of everyone else to entry, but the gap is closing quickly as the overall capability of KY does not justify their higher price. On the SPI front, Cyb

Operation features of many devices, machine components, instruments depend substantially on state of their surfaces. Selective surface processing by high-intensity energy beam (ion, electron, laser treatment) is one of the most perspective directions

What's important in stencil printing (which differs from screen printing) is providing a consistant volume of paste at each interconnect. The process window varies in proportion to the pitch. More than 60% of all defects are related to solder depos
