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

The company that I work for is a high-mix, mid-high volume manufacturer, and we also chose the YesTech AOI equipment. We currently have a YTV-2050 (the conveyorized machine with 5 cameras), and also the YTV-1000 (table-top version of the YTV-2050, wi

I�m interested in the F1 model, due to the possibility of this system to be configured with 1 top camera and 4 side. We are manufacturing 0402 and 0.4mm fine pitch Lead Free, and our PCB�s quality is not very good. With just one camera are you able t

Hello James. I've got a YesTech YTV-2050 system at work with one top-down camera, and 1 side-view camera for each of the four sides. I do have the side view cameras being used for automated side inspection. There are some parts with markings that are

We currently use a YesTech M1 system and we are looking to buy another. Two important areas to look at when pursuing AOI equipment: 1) Camera resolution 2) Light sources Depending on your needs, camera resolution can be important depending on the si

We did extensive side by side (by side) testing of three AOI machines Omron, YesTech and Mirtec. In the end, even with weighted scores, the difference in the top two machine was still only four/tenths of a point. Third place was a distant 14 points

We have one YesTech F1 working and a second one purchased on the way. So far, in my half year experience with it, we check solder and lifted leads with TOP cameras. The only ocations I use side cameras are when I have to inspect odd components that

In my experience, the best way to do a lifted lead inspection on a QFP is by laser height measurement. It is very difficult to consistently catch a lifted lead with only a top down camera. As you say, too many false calls, and still some escapes.

Have you thought about an AOI system? With the system we have where I work, I'm able to run queries that'll tell me DPMO, yield, and pass/fail rates on a board level, part level, and opportunity level. Furthermore, this data can be broken down to see

3D imaging refers to the acquisition of images from multiple perspectives using, preferably, multiple sources of illumination, while 2D imaging refers to the acquisition of an image from one perspective. An AOI system with 3D imaging is able to acq
