New E-motor IP68 Encapsulated Precision RTD Temperature Sensor
A new IP68-rated sealed Pt temperature sensor elements from Heraeus suitable for use in e-motors applications from ATC Semitec
The new IP68-rated Heraeus EC3032 Pt1000 temperature sensor assembly is ideal for use in e-motor applications. With a temperature range of -50°C to +200°C (with a short-term rating of up to 250°C for 50 hours) it offers precise, and robust temperature sensing solution for harsh automotive environments. In
addition, internal results confirm that the sensors are both oilproof and oil-tight. To that end Heraeus are currently applying the EC3032 for AEC-Q200 component approval. The sensor consists of a Pt1000B element terminated onto 24AWG PTFE wire and then encapsulated in a tough high-temperature shrink tube that is back-filled. This creates an IP68 rated sensor that has a dielectric strength of 6kV. For further information call the technical sales team at ATC Semitec on 01606 871680

Round IPS Wide View TFT Displays No longer is it necessary to use a circular bezel over a rectangular display to create the perfectly round screen that potentially your product and application calls for. Choosing one of Craft Data’s round high specification, modern looking, highly reliable chip-on- glass (COG) TFT displays for your next product could give you a more aesthetically pleasing look and possibly the edge over your competitors model. Currently we have four sizes available, diameter 1.3”(240xRGBx240),
2.1”(480xRGBx480), 2.47”(480xRGBx480) and 5.0”(1080xRGBx1080), all are high contrast IPS “All View” displays offering ultra-wide viewing angles (80°/80°/80°/80° minimum), a 16.7M colour palette plus a high brightness LED backlight all contributing to produce an excellent optical performance which enables designers to build vibrant and dynamic GUI’s. All models feature a low drive voltage of between 1.8V and 3.3V and have flexible communication via an SPI, 16/18/24 Bit RGB or MIPI interfaces with some models offering dual options on a single display.

Could Rental Solve Your Test Equipment Challenges?
With equipment shortages and long lead times set to continue, supplying engineering teams with the right equipment at the right time remains a real challenge for project owners, engineering leads, and operations managers. Rental offers an immediate solution, with equipment often dispatched within 24 to 48 hours, fully set up, calibrated, and ready to deploy to keep projects moving.
Renting also brings a range of additional benefits. Affordable, regular payments replace large capital outlay, and all- inclusive pricing eliminates the hidden
costs of ownership. Downtime disappears with replacement instruments provided during any maintenance or calibration periods, and rental also offers an opportunity to try out new equipment before you commit to a purchase. The flexibility of rental makes it easy to adapt as project requirements change, and by only paying for what you use, equipment utilization is always kept high.

www.electronicsworld.co.uk Tell me about test strategy!
Test Strategy for Assembled Printed Circuit Boards How do you (as OEM) keep the quality and costs of your (outsourced) production under control in today’s miniaturization of electronics? Testing today’s electronics, where not all nets can be provided with test points, is becoming increasingly difficult or even impossible using traditional test methods. But the production chain also raises new questions. How do you keep track of what is being produced for you and what can you do, for example, to relieve your EMS partner and find solutions together? This process starts in the design phase of your electronics with the definition of a suitable test strategy. Already in this phase it is important to analyze which test methods can help you to achieve the desired quality and the associated fault coverage. This knowledge helps you to coordinate the test options with the manufacturer of your electronic assemblies.
Testing Methods
Three different fault detection methods (Inspection Techniques, Structural Testing and Functional Testing) can be used together to achieve a fault coverage such that no PCBA leaves the factory with a manufacturing defect or functional fault. When developing a test strategy, many factors must be considered to determine which test and inspection methods will be used. The goal is to maximize the fault coverage, but not always at any cost.
Inspection and Electrical Test Inspection techniques are part of the assembly process and are implemented in different ways
at different factories. The minimum requirement is visual inspection by the operating personnel (human eye). While for higher volumes this inspection is automated using AOI (Automated Optical Inspection) or X-Ray systems.
In addition to the inspection, an electrical test is needed to find any faults in the assembly. Here some questions need to be answered: What type of testing should be done – Structural only or Functional or both? Who is responsible for the development of the tests and where will the tests be performed later – in the factory or in case of contract manufacturing (EMS or CM) at the OEM?
JTAG Technologies For more than 25 years JTAG Technologies has been solving the quality needs for many companies worldwide. Every manufacturer has its own test challenges, what are yours? We would be happy to analyze the possibilities together with you. Let us take a look at the test coverage and the resulting quality of your products. Together we analyze lead times, costs and work out reasonable overall solutions.
