We've done the same....Juki 2000 series versus Yamaha / Assembleon XT series....we found out that Juki is far better, more efficient, and easy to maintain...we bought 2020 last year and found that we made the right decision... Juki is the Best !!!

Hi Jax, After component placement, all melf diodes being checked & found no touching each other. Unfortunately, after reflow those MELFs are shorted.

Consider: * Printing: errors [ie, insufficient, excess, skipping, etc.] paste doesn�t roll in front of squeegee, paste adheres to squeegee at the end of stroke, paste does not release. * Component placement: orientation, wrong component, missing comp

Ken, Thanks for the info but I do not see where this addresses my main concern of placement using an alternative to the tweezers and keeping the board on the conveyer. Please let me know if I am missing something. Thanks, Kevin

Has anyone done study or have feedback on 0402 placement capabilities of Europlacer Vitesse? What kind of common issues were seen when placing 0402s with the machine? We know the machine is rated for 0402s but don't know how reliable it is. Rgds, P

We are a manufacturer of placement machines and I believe that you asked if there was a reference that can be used to determine the tape sizes for most SMD packages. We review the catalogs from Practical Components and Top Line to determine tape size

Thank you pr. It was much appreciated. Is this mark normally act like a global fiducial/local fiducial for mBGA ? Is this a standard mark that can be read by the placement machine? what is the typical size of this mark ? are they masked ? thank y

I run 0201 on a 5 mils stencil with openting of 15X12 and did not have any issue. The major concern is the placement and CP643 did very good job. Type 3 solder pastes was used. Good luck.

Can someone please point me to some good technical papers on the Ag Epoxy process covering- printing, dispensing, component placement and curing and on flexible & ridgid substrates too? Are there lots of you out there doing this process? Thx.

I used once flux cream on a glass plate for a customer application, which should simulate almost the same cohesion than solder paste.
