Using a X-Rays machine, we have noticed that one component we are using has the silicon die bonded at an angle in the package. Have you ever seen something like this? I'm not sure if it's intentional or a manufacturing error.

The Angle view (or Variable Angle Viewing) gives you another perspective on joint inspection. Glenbrook has two great illistrations on the varible angle viewing literature (.pdf file): Here are a few examples: 1) Looking straight down on the ball..it

Wister, I agree with the other comments as far as challenging the customer, and minding proper height/width or better yet area aspect ratios. Let's assume you need to go with a .012" stencil for arguments sake. Talk to your stencil supplier about h

Here is a study on printing factors study on CSP [we understand that you asked about fine pitch, but hey, it's close and FREE] http://nepp.nasa.gov/docuploads/2A524D62-7032-4C0D-BBDED6CFFC2FA07B/SMTA-I-Joint-Paste-2004.pdf It's interesting that whi

Chunks, Nozzle unfriendly? Maybe it should be called nozzle hostile. Depending on the machine and lighting a nozzle with a 1.8mm tube might work. In English units that would be a .072 OD with a .062 ID. The area such a nozzle would pick from is the 6

MACHINE CONFIG> MOUNT R ATTR. You have the choice of REL or ABS. Until you get these sorted and understand the differences you may struggle a bit with rotations. Should be in the manual. I always ran REL, which means the mount angle is relative to th

This problem has become a real issue with the tacky silicon used in many LEDs. Cree has recomended that the pull off angle be changed for the cover film as mentioned by the previous commentor. With these new silicon LEDs they are recomending teflon o

Steve, someone somewhere is feeding you a line!! if you increase the draft angle from || to / \ on your laser cut stencil you increase the surface area of the side wall and hence increase the likelyhood of the paste sticking in the aperture. Whats m
