AOI should be operated by a machine operator. I could get a monkey to stand around pushing buttons. A machine operator job responsibilty is not to change feeders and push buttons. They have to monitor the process for missing parts, misaligned, and pa

To recap: 1) The machines use laser centering, not mech jaw centering. 2) The X7Rs are scattered on the board, center and edges. Improper de-panelization would favor damaging the parts near the edges of the board; this is not the case. 3) Both ROH

Never had anything to do with Soltec so I cannot comment on their service. However. You must realise that machine manufacturers/distributors incur a cost in storing spare parts and making them available for immediate delivery. They are not held on co

Great work Amol, Please keep us posted about the results of the x sectioning. I personally don't believe that the cracks are due to non-eutectic properties of SAC. Because the alloy is only 4�C off eutectic and when a solder joint exits the solder

There is learning on all brands requiring fine tuning the test parameters. The first point is not to allow defects to escape. Many brands can do a good job with preventing escapes. The struggle with all the brands becomes false calls. The companies r

Amol, I thought I answered your question in another thread, dude! Anyway, to re-iterate. Yes, I was able to pull it off a hybrid profile. The LF BGA passed tensile testing, but no, it wasn't thermally cycled or stressed first to expose any latent

Efren, Most of the previous posts offer valuable information. Certainly you should consider panelization of the individual circuits. Otherwise you'll waste valuable production time passing 3" boards along the line. Your orig estimate of min thruput

I might be wrong since I don't know this piece of equipment but I think ROL might be a better measure. For 63/37 it used to be 20 ppm ROL (residual oxygen level) was about what you needed for a reflow oven. This is to take full advantage of all tha

We evaluated the OM338 from Alpha and it worked great! Looked like crap, though, compared to the other products out there. When I set the boards out in front of the Alpha sales guy to show him the difference in appearance between his boards and the
