| | Cpk's on top flight ovens (e.g., Conceptronics, Heller, Electrovert, Vitronics) vary wildly, from 1 to 2+, between different supplers. The suppliers don't seem to understand Cpk's. A supplier's rep whose oven has a Cpk of 1.0 told me: | | 1. C

Good luck in your conquest. I have been struggling with the same issues for some time now. I have made the following conclusions. First, it is nearly impossible to establish parameters in SMT to perform X-Bar and R charts. Electronics is not as cl

The most effective method is to monitor both printing results and parameters. Periodically (maybe once per month), run QCCalc or another program to measure the machine's capability to hold its set parameters. I also run control charts on the paste h

Hi everybody, This is a simple posting to initiate a discussion on different ways to troubleshoot, improve, and control the Stencil Printing Process SPP in SMT manufacturing. There are many SPC, ANOVA and other analysis techniques that provide insi

Hello Rohan, this is starting to date nearly 6 years ago but I will remember everything I can, we used a custom interface to input data and everything was stored in a very large database on a specific server only for quality data, I think we used Ora

Hello Dave, I can understand why you might not use the auto-correct function based on the time it takes to perform the operation. I question why there is an auto-correct function in the first place? If I understand the way this works correctly, the m

Hello James, That sounds very interesting. I didn't know a system like this was available. What is a vision check machine? Is it a software monitoring tool that is installed on manufacturers equipment to evaluate the conditions you mentioned? I'd lik

This is a pet peeve of mine. The paste height requirement is generally asked because the customer has no clue about screen printing, but knows to ask this question. If he did know even a little about printing, he�d ask you to assure the �volume� of

It looks like there's another one or two threads somewhat similar, but allow me to pose another. We've only about two years experience in SMD production, and we're just starting to really ramp-up. As we stand right now, I'm not recieving informatio
