Deionized Water: The Gold Standard for Electronics Cleaning

When washing electronic boards, a common concern among technicians is the purity of their water. Rightfully so because technicians don’t want filthy trace deposits left under and around sensitive components. Some might ask, “If water is bad for electronics, why wash them in the first place?” Washing boards is a common process in the electronics industry because when a board is manufactured or reworked, there is a substance called flux that needs to be removed or it will cause corrosion and longevity issues. Water is a readily available and an effective solution for removing flux. However, technicians need to choose the water carefully.

There are several different levels of water purity. Starting with the least pure option, typical tap water can be used for washing boards. The next quality improvement is using carbon filtered water which marginally helps with the contaminants in the tap water. A quality level above that is Deionized water (DI water) which is commonly used in the board washing process at high quality electronics facilities. Using DI water for the board washing process is optimal due to the absence of contaminants in the water. Because DI water is the purest form of water, electronics manufacturers focused on quality use this as a standard for board washing.

IoT, Here We Come! Ubuntu Core Announced for TS-4900

In a joint press release between partners Canonical and Technologic Systems, the pairing of Ubuntu Core and TS-4900 was officially announced.

We couldn’t be more excited!

We feel that Ubuntu Core is going to make a big splash in the IoT world for its security, ease of management, and flexibility.  Combine that with our rock-solid, industrial TS-4900 and you have yourself a reliable, production-ready IoT device.

We’re very honored to be featured in the Ubuntu booth at the Mobile World Congress in 2017.  For more information, please take a look at the press release, Bringing Ubuntu Core to the i.MX6 Based TS-4900.  If that isn’t enough to quench your thirst, take a look at our Ubuntu Core Powered Embedded Systems page.

 

Reach Out and Touch Something (Capacitive vs Resistive Touch Screens)

You only have to go as far as your corner coffee shop to realize the new human-machine interface (HMI) preference is screens. From the touchscreen Point of Sale systems to the multitude of people interacting with their phones and mobile devices, screens are king. Industry is following suit and the choice for HMI is quickly migrating away from the keyboard and mouse and towards the screen. With the abundance of touch screens on the market and the decrease in costs there has been a marked increase in their market share and penetration. When picking a screen it’s important to determine which is better for your purposes: capacitive or resistive?

Practical Guide to Getting Started with the TS-TPC-7990

Introduction

The goal of this practical guide is to get you through the basic steps of getting your TS-TPC-7990 up and running so you can begin development. It’s mostly an extrapolation of the official TS-TPC-7900 Manual, but provides a more practical and casual approach in setting up connection, networking, and general development environment.

Collaborative Digital Signage Project

Real-Time Company Announcements and Information Using Multiple Touch Panel PCs

Abstract

This project aims to improve the communication of company events, key performance metrics, and collaboration through several strategically mounted touch panel computers (TPCs) throughout the building. It also serves as an inspirational digital signage application for potential customers using our TPCs. Skimming through the technical details, you’ll find the screens are powered by our very own TS-TPC-8950-4900, a 10” resistive TPC running Debian Linux, a fullscreen, kiosk-mode browser, and a custom node.js web app.

Our Research in SLC NAND Endurance on EECatalog

This whitepaper is the result of many months of effort, working together with our customers in the field, in troubleshooting and coming up with an “smoking gun” explanation and solution for a decrease in SLC NAND flash endurance.  It’s valuable information for any embedded system users who rely on their data and filesystem to be free of corruption.  Be sure to read the full whitepaper at SLC NAND: Secrets Exposed at EECatalog.com.

While you’re at it, you may want to take a look at our related articles, featuring the solution we came up with for the decreased flash endurance, XNAND2: NAND Device Driver for Todays Lower Endurance SLC NAND, and how to further prevent data loss, Whitepaper: Preventing Filesystem Corruption in Embedded Linux.

Demonstrating the TS-SILO Power Reserve Solution

Eliza Nelson, our Field Applications Engineer, takes some time during the Embedded Systems Conference (ESC) in Minneapolis to show us a demo on the new TS-SILO super capacitor, power reserve solution.  In the video, a TS-7680 equipped with onboard TS-SILO gets it’s power feed mercilessly taken away in an ever lasting loop every minute or so.  Thanks to the TS-SILO, it has time to gracefully shutdown each time.  Power is restored, the TS-SILO gets fully charged again in under a minute, and power is ripped away again.  Enjoy the video!

grow-sd: Script for Resizing SD Card Partitions Using sfdisk

The purpose of this example script, which we call grow-sd , is to demonstrate a use case for using sfdisk, or what I like to call ‘scripted fdisk’, to modify a partition on an SD card provided by Technologic Systems.  This is useful when your production SD card image, originally copied from a 512 MB SD card, is being written to a much larger capacity SD card, and you want the additional storage space.  Keep in mind, the script itself is specific to Technologic Systems’ embedded boards, and only applies to those images which are shipped with four partitions (ie. TS-7350).  However, this script also generically demonstrates and example usage of sfdisk .  We thought it’d be helpful to publish in hopes it would be useful.  Feel free to modify it to fit your requirements.
