Hi, I think the standard was IPC 6850. But I will recommend to go directly with the sigma test. Place parts with the machine and measure the placement accuracy on another machine. 4-5sigma at 50um should be a good machine. If they have sigma in thei

How much cost do you absorb in touchup and replacing missing parts, and how does it compare to the cost of operating a reflow oven that runs whenever you have product available to process? I don't necessarily have an answer for you but I'm having a

The mounted panels (8" by 8") are stacked in carriers, 0.5" between panels, 20 panels per carrier. There are no missing parts or other damage due to carelessness. Anyone bumping a panel is summarily executed by the company firing squad. As someone

You have a lot more problems than what you are asking about. If you are running a shop that is un-air conditioned and high humidity you will have nothing but trouble in ALL aspects of your operation. I know this is harsh but I am really surprised in

From your question you must be having rework issues due to the extended wait before reflow. What is the cost of the rework compared to the cost of just running the oven? Maybe you should look for a better used reflow oven that won't turn your shop

Sorry...I was depending on the formatting to indicate that my comments were in response to qdp's comments. Whether he/she likes it or not, your process is probably well entrenched and you were asking for help with it. I didn't think his opinion as

255 shuts it off, but if I remember correctly 254 still uses vision but passes almost everything? You might want to give 254 a try before resorting to 255. I believe 254 will still correct some pickup offsets. And iirc 255 isn't in the manual but so

Check the image using the fast inching [F] and axis selection [2]. After vision error, press [F] then [2]. The monitor will display a binary images. You will now have a visual look on how the error occurs. Adjust the CCD level of the camera until you

Hi, When you tried vision type 254, did you change the size of the body? On 254 the body size should be the outer dimension of a component, so on a PLCC (or any other component) the leads should be included in the body size as well. One other thing r

I think you'll find that the YTV-F1 system is comparatively priced at around $100K. Plus it has a color camera and more functionality than what you will get with the Landrex system. You might also look at what Mirtec has. I have only used them for
