Wafer level chip scale package (WLCSP) is true with low cost by eliminating substrate. The direct chip-to-board attach through solder joints provides interconnect inductance and resistance, as well improved thermal performance. These properties make WLCSP a packaging format suited for 5G radio frequency (RF) applications where minimized size parasitics performance are critical. Due to the dissimilar between board, reliability of can be challenging. This article reports study using 45nm RFSOI...

The acceptance of Wafer Level Chip Scale Package (WLCSP) technology is significantly increasing for use in small devices such as mobile phones, wearable, RF antenna packages, and health monitor sensors. WLCSP structures can have a few thin redistribution layers (RDLs) between the chip surface printed circuit board (PCB), or interconnectors be placed direction connection to back end line (BEoL). Due high coefficient thermal expansion (CTE) mismatch silicon organic laminate, chip's level...

By thinking out of the box, Baldor Electric Company has been able to save about $1 million a year in energy savings corporate-wide for each last three years. Over $100,000 this comes from our Westville, OK plant. This paper will discuss Baldor's success reducing utility costs at motor plant Oklahoma by working with local electricity supplier (Ozarks Cooperative Corp) and practicing peak shaving during summer months. After had adopted all current saving methods such as use NEMA Premium/spl...

On December 19, 2007, the Energy Efficiency and Security Act of 2007 was signed by President Bush. This law mandates upgraded electric motor efficiency beginning in 2010. Canada is expected to follow with a similar requirement January 2011. Other countries are also mandating MEPS (minimum performance standards) for motors. In response need leadership international arena, National Electrical Manufacturers Association (NEMA) has responded creating new NEMA Premium <sup...

The primary standard for low voltage, random wound, induction motors in North American countries is National Electrical Manufacturers Association (NEMA) MG 1-2011. In some other countries, the governing International Electrotechnical Commission (IEC) 60034-1:2010. This paper compares performance, design and construction details of NEMA IEC three phase, wound alternating current (AC) motors. Not only are there obvious mechanical mounting dimensional differences, but practices electrical norms...

Wafer level chip scale package (WLCSP) is a low cost and high performing packaging format suitable for radio frequency (RF) applications where minimized size parasitics are critical. But it raises challenges to reliability. This paper reports reliability study of WLCSP using GLOBALFOUNDRIES' 45RFSOI technology. Based on comprehensive testing deep understanding the failure mechanisms, design optimizations chip, board interconnect were implemented. was significantly enhanced.

Many motor users may be confused when it comes to calling out the appropriate standard or specification for their applications. Some standards are better suited certain applications than others. By thoroughly understanding what each was developed for, most can chosen. This work discusses IEEE 841-2001, API 541 4th edition, and 547 standards, provides guidance as applicability of each.

On December 19, 2007, the Energy Independence and Security Act of 2007 was signed by President Bush. This law mandates upgraded electric motor efficiency beginning in 2010. Canada is expected to follow with a similar requirement January 2011. Other countries are also mandating MEPS (Minimum Efficiency Performance Standards) for motors.

The U.S. Department of Energy has regulated efficiency standards for electric motors since 1992. Recently they have begun the process creating a rule to regulate motor driven systems - pumps, fans and air compressors. Significant energy can be saved with more efficient than by regulating components alone. These regulations are expected wide-ranging effect on products that available in market. Pump been studied final pump testing was issued January 26, 2016. group studying fan also started...
