A suggestion for your stencil which works is as follows. Cut your stencil aperatures beyond your pads to a length of 0.1mm , this then allows the paste to pull back into the pad creating a blob of solder which can be inspected by AOI.Best length and

I have been using ICT for a number of years. It is still a viable resource for catching defects in the production process. AOI doesn't catch everything, such as bridging on QFN or J-lead devices (this will depend on the type of AOI and camera syste

I agree, the only way to "truly" inspect a QFN is with an X-ray. But this might be over-kill for him. He asked about soldering, not inspection. We use QFN's regularly and you can inspect these parts from the side to see if they are soldered. Unfo

How do you evaluate the soldering quality for those QFNs? X-Ray or AOI? For some QFNs (and other bottom termination components) it's not supposed to have solder fillets on toes. It's also noted in IPC-A-610 (Rev.F 8.3.13). Take a look at your QFN ch

Good Morning Bryan, We are using Mirtec MV-3 AOI's with 4 megapixle cameras. We use them for 100% post reflow. We are checking, presence, polarity, value, solder, bridging,component height for BGA, QFN etc... and 1st piece validation for machine set

Hi, is someone who has experience in programming SI-V200 AOI machine? I'm curious how long takes to make a new program for a board with 50 types of components (30 ssop, sop, qfn, BGA and the rest up to 50 components 0603, 0805, 1206), without having

if you want to get some sort of a joint even to allow AOI to inspect you can overprint on on the outer lead by 3 thou or so. This will give you a joint that can be seen from the side for inspection purposes.

http://www.aoisystems.com/ I was at the SMTA show and saw this company's booth. It looked like a good product at a good price but it doesn't do 3D AOI. The sales person was saying that 3D AOI is only useful in cases where a lead pin is hanging in

We are considering a tabletop AOI primarily for rework purposes. In 95% of the cases we would NOT have centroid data NOR Gerbers, The area we would inspect would be in and around the BGA, QFN or LGA being replaced. In addition we would want o inspe

Hello all, We are looking to purchase another AOI system with side angle cameras. Currently we are using a YesTech M1 system that has only a top-down camera (it can't be upgraded with side cameras). Does anyone have experience with YesTech F1 sys
