NXP Reveals World’s Smallest Logic Package with the Largest Pads

NXP Semiconductors N.V. (NASDAQ: NXPI) today announced the new SOT1226 “Diamond” package – the world’s smallest general-purpose logic package, featuring a unique pad pitch design. Measuring at 0.8 x 0.8 x 0.35-mm, the new SOT1226 is a leadless plastic package 25-percent smaller than the SOT1115, previously the world’s smallest logic package, also from NXP.

Despite its smaller package size, the SOT1226 saves engineers time and costs by offering a 0.5-mm pad pitch that is 50-percent larger for easier soldering. Ideally suited for leading-edge portable devices such as smartphones where PCB space is critical, the unique form factor of the Diamond package enables device miniaturization by offering a space-saving logic solution without the added manufacturing costs associated with smaller pad pitch patterns.

Typical manufacturing processes for packages use a small 0.3-mm or 0.35-mm pad pitch, requiring Electronic Manufacturing Services (EMS) and assembly houses to use a step-down mask in order to successfully mount the devices on the PCB. Due to the Diamond package’s larger 0.5-mm pad pitch, a step-down mask is not needed during the soldering process, saving costs for the manufacturer. In addition, the larger pad pitch of the Diamond package offers greater contact area, resulting in easier component placement, as well as improved joint strength and robustness, while reducing the risk of short circuits. With larger pad pitches, PCB assemblers can thus avoid costly mistakes such as solder bridging, or the formation of accidental bridges between contacts, which can render electrical devices useless.

“Mobile designers are constantly faced with the challenge of adding more functionality and features into portable devices while using less space, which in turn introduces new challenges,” said Kristopher Keuser, director of marketing, Logic business line, NXP Semiconductors. “NXP’s new Diamond package is a game-changing solution that allows our customers to design within smaller geometries without increasing manufacturing costs, and to standardize their entire product portfolio. It underscores our commitment to leadership, innovation and understanding of a market that is driven by the need for smaller, cheaper and more reliable solutions.”

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
