the American auto market sim- ply by producing a more reliable vehicle. In ICE vehicles, some of the
biggest reliability gains came with the introduction of cleanli- ness specifications for particu- late in engine and fuel systems. Over time, a great amount of thought and attention to detail helped create robust cleanliness standards for ICE vehicles. In the early 2000s, German au- tomakers collectively authored VDA 19.1 “inspection of technical cleanliness,” which was eventu-

ally widely adopted internation- ally as ISO:16232. However, no such standard
exists for printed circuit boards in the automotive industry. EV powertrains have 60% fewer components than ICE vehicles and they have no fuel nozzles, less moving parts to jam and no cylinder timing to regulate. Fewer moving parts would seem like an excellent roadmap for an even more reliable vehicle. Yet, consumer reports
ranked EV’s among the least re- liable vehicles on the market today. Many of these failures
present as No Fault Founds (NFF) or No Trouble Found (NTF) and are directly tied to an intermittent electronic issue. While cleaning is not guaranteed to solve every intermittent issue, having a cleanliness standard would greatly reduce these prob- lems.
The closest thing the PCB
industry has to a cleanliness standard is IPC’s JSTD 001, which simply calls for “objective evidence” in the manufacturing process. This standard is under- standably broad because it cov- ers such a wide range of indus-

tries and applications. Even within the high reliability sector, requirements for circuit boards going to outer space are far dif- ferent than boards going into the human body. Although we don’t always
think of it in this way, the auto- motive industry poses some of the harshest environmental con- ditions for PCBs. Automotive PCBs must contend with winters in Detroit, summers in Arizona, the constant rain of the Pacific Northwest, not to mention the salt and humidity of Florida, and that is only in the United States. The combination of a wide vari- ety of environmental conditions, passenger safety considerations and the importance of general re- liability in the automotive indus- try demonstrate the need for an automotive standard for PCB cleanliness along the lines of VDA 19.1.

MikroE Launches New Version of IDE
BEOGRAD, SERBIA — Mikro - Elektronika
(MikroE) has
launched a new version of its in- tegrated development environ- ment (IDE) NECTO™ Studio 4.0, which now includes full re- leases of mikroC AI for ARM, PIC, PIC32, dsPIC, and AVR. The update also adds GNU C for ARM, and makes using Planet Debug™, which enables design- ers to develop and debug embed- ded systems remotely over the internet without investing in hardware, more powerful and easy to use. One of the most significant
new features of NECTO Studio 4.0 is the natural and seamless integration of the GNU C compil- er for ARM. This extends support for a range of cores including M0, M0+, M3, M4, and M7 from vari- ous vendors such as STMicro- electronics, Texas Instruments, and NXP. Another new addition is the
introduction of NECTO Studio Plot, a real-time data collection tool that requires no additional hardware or bulky libraries. With just a single line of code, develop- ers can log data, which is collected in an Excel-like table view. Contact: MikroElektronika,
