In-Circuit Design Pty Ltd (iCD), Australia, developer of the iCD Design Integrity software, has released the new iCD Materials Planner software to add to the Stackup Planner functionality. This will be rolled out to iCD support customers as an update to their current software.

The Dielectric Materials Library, which complements the iCD Stackup Planner, has

• Over  33,000 rigid and flexible materials up to 100GHz
• Produced by over 60 different manufacturers
• Containing over 700 series of materials

So, it is often a daunting task to ascertain which is the best material for an application. The iCD Materials Planner allows you to compare dielectric materials based on manufacturer, fabricator, frequency, dissipation factor (loss) and dielectric constant. This enables the designer to make an informed decision on which material is best for his application.

Generally the selection metric, for dielectric materials, is the amount of loss that a transmission line can tolerate and this is proportional to the frequency and rise time of the signals. The iCD Materials Planner is subdivided into five default TABs which gives the novice high-speed PCB designer a heads-up as to what to select for his application.

• Ultra Low Loss (Df ≤ 0.005)
• Low Loss (0.005 < Df < 0.010)
• Mid Loss (0.010 < Df < 0.015)
• Standard Loss (0.015 < Df < 0.02)
• Basic FR-4 (Df ≥ 0.02)

This is similar to a typical competitive analysis that a material manufacturer may present for say Isola vs Ventec & Rogers – but is far more comprehensive with over 60 vendors and 700 series of materials to choose from. Alternatively, a profile for each PCB fabricator that you usually deal with can be set up. This will display the complete range of materials that each Fab shop stocks ranging from basic FR-4 to low loss materials. This also enables the comparison of competitive Fab shop capabilities.

OnePlus has unveiled an official schedule for software updates and there’s a pleasant surprise – the OnePlus 3 and 3T are not getting left behind. The schedule is two-fold – regular updates and security maintenance.

For two years after their launch OnePlus phones will get new Android versions, new features and bi-monthly security patches. After that there’s an extra year of bi-montly security patches (as in every two months). This schedule applies to OnePlus 3 and all phones launched after it.

Speaking of, the OnePlus 3 and 3T will receive their final Open Beta later this week and with that the program will close. Beta testers will be migrated to a stable version at the beginning of July. That’s not the end, however.

The 3 and 3T will continue getting regular OTA updates until November 2018. That’s two years after the 3T launched, so the 3 is getting a few months extra. Anyway, after that these two phones will go into security maintenance for a year.

This is a great move from OnePlus – not just the length of the support (only Google promises more), but that there’s an official schedule at all. This takes away the guesswork for anyone who wants to keep their phone for more than a year (and let’s face it, some phones get abandoned even sooner).
