Boost Your Manufacturing Automation and Intelligence

6/20/2023

Manufacturing Automation & Intelligence refers to the application of technology and data-driven solutions in the manufacturing industry to improve efficiency, quality, and profitability. It involves the integration of advanced technologies to automate manufacturing processes and make them more intelligent.

Manufacturing automation aims to minimize human intervention in the manufacturing process, reduce manual errors, and optimize productivity. It involves the use of automated machinery and software systems to perform tasks such as assembly, inspection, packaging, and quality control. Automation helps manufacturers to streamline their operations, reduce costs, and increase production speed and output.

Enhancing Product Reliability with Bed of Nails Testers

5/24/2023

Bed of Nails Tester Basics
In the world of test engineering, specifically for electronics manufacturing and testing, certain tools, software, hardware, and test systems have become indispensable due to their versatility and effectiveness. One such tool is the "Bed of Nails Tester." This device, despite its intimidating name, plays a crucial role in ensuring that electronic components and circuits function as intended. As a test engineer or manager, you'll need to know the basics of the bed of nails tester, its function, how it works, its components, and why it's such a critical part of electronics testing.

Adapting Existing Test Systems To New Product Variations

5/8/2023

Adapting an existing automated test system to fit a new hardware, firmware, or electronic product can be a complex process that requires careful planning and execution.

Here are some general steps to follow:

Evaluate the new product variation: Begin by thoroughly evaluating the new product's specifications and requirements, including any differences or nuances from previous products that may impact the test system.
Identify the necessary changes to the system: Based on the evaluation, identify the necessary changes to the test system hardware, software, and test procedures to accommodate the new product.
Modify the hardware: Modify the test system hardware as needed to support the new product. This may involve adding or replacing components, such as fixtures, connectors, or adapters.
Update the firmware: If the new product has different firmware than previous products, update the test system's firmware to support the new product.
Update the software: Modify the test software to support the new product, including any necessary changes to the user interface, test sequences, and data analysis. This can often require a LabVIEW or TestStand expert.
Validate the changes: Before implementing the changes in production, validate that the updated test system can accurately and consistently test the new product.
Implement the changes: Once the changes have been validated, implement them in production and train any necessary personnel or test engineers on the new procedures.
Test and optimize: Test the new system thoroughly and optimize as needed to ensure efficient and effective testing of the new product.

Throughout the process, it's essential to communicate with all stakeholders involved, including design and engineering teams, to ensure the test system accurately reflects the new product's requirements and specifications.

A Bridge (of the Enterprise) Too Far

11/9/2022

User interface design has to balance a number of competing goals, mainly:

Functionality
Responsiveness
Aesthetics

That was the case with this project for an in-vehicle data collection system. The interface was a touch screen that requires input from the same person driving the vehicle. It was very important that the interface be simple and easy to understand and fast to work with, to keep the driver's eyes on the road.

We started with a typical LabVIEW interface. It worked, but it was a bit boring. It also suffered from being difficult to see. The gray background did not provide much contrast while day driving.

The Leaving Edge of Technology

11/3/2022

You built a great ATE system, but it’s been a while…maybe a long while.

Is it running LabVIEW 6i?
Maybe still on Windows XP?
Are you scrounging for backup parts on eBay?

Don't be embarrassed, we've seen it all. Let's get you upgraded.

Classic NI Software

11/1/2022

Another blast from the past. Cleaning the office can be such an adventure. Do you remember the days of the LabVIEW Test Executive? And the introduction of a new product called "TestStand"? Version 1. Compatible with all versions of Windows: NT, 95, and 98!

Years of projects later, it is fun to look back and remember all the hours I spent using these tools.

I heard it on the VINE

10/31/2022

By Tony Kuiper

In many projects involving design, we find ourselves conflicted between simplicity and functionality. Machine control and communication between components is not immune to this.

As we were designing a somewhat complex hardware simulator we reviewed the generally available COTS solutions, finding a few that might work well enough, but didn’t quite meet all the requirements for how we wanted the software to be able to interact with the large number of offboard peripherals we needed, or were a bit heavy on the hardware side.

We saw this as a two-fold problem: hardware and software.

Simple hardware communications solutions like I2C and SPI were readily available but lacked the intelligence that smarter communications would provide. RS485 came close with its multi-drop capability, and CANbus fixed the issue of bus contention, however at the expense of additional interface components and cabling considerations, and a significantly heavier firmware load. RS232 was very simple to implement but was only point-to-point. None of these off-the-shelf solutions really scratched the itch.

Blast from the Past

I got a blast from the past cleaning up at the office. "The only LabVIEW subscription with VI software included".

The disks are still attached, but I can't find the opening for them on my laptop.

It Takes Two Weeks to do Anything

12/21/2021

Estimating is hard. So hard that many engineers don't really try; everything they estimate will take two weeks. Change a button from red to blue: two weeks. Write a specification for a new software feature: two weeks. Build a rocket for human flight: okay, most engineers are smart enough to estimate at least 3 weeks, but you get the point.

Of course, “two weeks” usually isn’t really an estimate at all. So, what do we mean when we say something will take two weeks?

“I am a good engineer. I can envision a solution, so I can probably implement it pretty quickly.” But seeing a path is not the same thing as walking that path, yet we fall for this trap easily.

“It takes what it takes. Don’t try to pin me down.”
“My job is engineering. Let the project manager estimate things.”
“I have no idea how long it will take, but it won’t be done tomorrow, so go away.”

We’ve probably seen all of these excuses used. We’ve probably used some or all of these excuses.
Estimating is hard, but it is a skill that is very important to your success, your company’s success, and your customer’s success.

What techniques do you use to estimate more accurately?

Simplify

11/9/2021

I love it when I’m working on a project and pieces fall into place that make it simpler. It is almost always a surprise. I am struggling through a problem, adding layer upon layer of complexity to try to handle issues, as engineers love to do. Then all of a sudden, something dials in. Sometimes it almost seems like the problem solved itself -- maybe it did, but my engineering ego still wants the credit. :) Let’s call it a team effort.
