Threebond Develops Low-Temperature Chip Bonder

The TB2217H low-temperature cure chip bonder from Threebond offers curing at 80C and addresses an array of chip bonding issues for manufacturers and rework facilities. This single component epoxy offers ease of handling by syringe and full compatibility with automated dispensing systems to enable chip retention on PCBs going through multi-station lines and wave soldering equipment.

By offering a low cure temperature of 80C with a 220s cure time, TB2217H can eliminate possible damage to heat-sensitive components while at the same time offering a high-speed snap cure of 60s at 150C where needed. Whether applied by syringe or print system the TB2217H offers an air-bubble-free solution to component retention with dispensing speeds in excess of 30K dph, good dot shape and without stringing and tailing.

Prior to curing it provides excellent tack strength ensuring no component movement or loss during population and handling, while after curing it exhibits exceptional bond strength with various types of component materials, claims Threebond. TB2217H is compatible with the DEK Proflow Direkt imaging system and is available in DEK Proflow cassettes.

Other packaging available includes a range of syringe styles, Fuji, EFD, Iwashita, Panasonic, as well as cartridges. It is suitable for either pneumatic, (time/pressure system), or positive displacement dispensing systems (helical screw system), or dispense jet systems. Similarly it may be used in a wide range of print type systems.

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.
