High Tg, Reworkable Underfill from Henkel Ideal for High Value, Fine-Pitch Area Array Devices

Expanding on its portfolio of advanced underfill materials, Henkel has developed LOCTITE UF3810, a new underfill technology that provides extremely high reliability while also allowing for easier reworkability as compared to previous generation products.

Designed to deliver superior performance and ease-of-use, LOCTITE UF3810 addresses many of the complex requirements associated with today’s high value devices, but does so in a formulation that has excellent processability.  The material is halogen-free, completely reworkable and has a high glass transition (Tg) temperature of 100°C, thereby delivering robust thermal cycling reliability for next-generation wafer-level CSP (WLCSP) and PoP devices.

As Dr. Brian Toleno, Henkel’s Global Product Manager for Liquids, explains, LOCTITE UF3810 is the go-to product for manufacturers seeking high reliability in a cost-conscious formulation. “With increasing device complexity comes increasing cost,” says Toleno.  “Assembly specialists want to reliably protect these devices but also have the option to rework them should any issues arise.  LOCTITE UF3810 provides high reliability and reworkability – a balance not readily available with traditional, low Tg formulas.”

Ideally suited for today’s handheld communication and entertainment applications, LOCTITE UF3810 delivers excellent drop and shock protection and improved thermal cycling reliability for fine-pitch ( 0.5mm pitch and below) area array devices.   In addition to superior performance versus alternative reworkable underfills, LOCTITE UF3810 also provides ease-of-use that lends to its process flexibility.  The material flows fast and underfills at room temperature and cures quickly at a moderate 130°C which, in addition to its halogen-free status, adds to the material’s sustainability through reduced energy consumption requirements.    These characteristics, in combination with its proven solder compatibility, make LOCTITE UF3810 a highly versatile, yet highly effective underfill system.

“This material’s value has already been proven in the handheld market,” concludes Toleno.  “But LOCTITE UF3810 has also attracted the attention of those in the defense/aerospace and automotive sectors, as it allows incorporation of CSP and PoP devices without any adverse impact to reliability.  For anyone seeking a highly reliable underfill system that allows cost-conscious reworkability, LOCTITE UF3810 is the obvious solution.”

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
