DEK has introduced Setup Verification and Traceability for screen printing, to prevent setup errors, maximize screen printing productivity and gather data for continuous improvement. Optional features also now allow manufacturers to achieve board-level traceability.

Includes software and hardware to automatically identify the stencil, paste and other setup variables as the machine is prepared. Verification compares the actual values with those specified in the product file, and can be programmed to halt the machine before printing commences or generate a warning in event of an error. Software supports 1-D and 2-D barcodes, and all data is recorded for analysis.

The optional traceability module and conveyor-mounted barcode reader identify each board entering the machine and link the board ID with the setup verification data, which is stored on the machine's hard drive. This delivers board-level traceability for screen printing.

Records setup variables, as well as ambient temperature and humidity, operator identity and line identity. Data is accessible via a network connection, can be copied onto removable media and can be used as input to statistical process control tools.

miniRaptor high-speed CNC machine is designed for speed and versatility - particularly when machining aluminum - in applications like micro drilling, milling, tapping and engraving associated with the production of panels, housings, enclosures and test fixtures. The compact version is suited to the typical electronic manufacturing environment.

Has 51 x 51" footprint, 20 x 20 x 8" working envelope that provides ample room for the prototype short runs typical of electronic R&D companies. Smaller bed size facilitates use of a solid slab of granite for the machining table that provides increased rigidity to minimize vibration.

Features a 60,000 RPM spindle with a 0.125" collet, a three-tool automatic tool management system, Windows-based control software, a PC with 256 MB RAM and 40 GB part/program storage, CD-ROM drive, 3.5" drive, USB port, 15" monitor, keyboard, hand-held controller, Ethernet networking capability, remote monitoring capability, a removable chip disposal tray and a full machining-area enclosure with an industrial-grade door safety interlock system.

Options include a 600W, 60,000 RPM spindle with 0.250" collet, a ten-tool automatic tool management system, a flat screen LED monitor, a Z-Correction Probe that recognizes irregular work piece topology and a 3-D probe extension that locates and compensates for material irregularities in x, y and z coordinates and facilitates reverse engineering.

PG0255NL series of low profile SMT flat coil inductors feature saturation current rating up to 30 Amps (A) and heating current rating up to 38A. Designed for the multiphase voltage regulator modules (VRM) supporting the increasing current needs of Vcore power in PC notebooks and other DC/DC applications.

PG0255.201NL, PG0255.401NL, PG0255.601NL and PG0255.222NL have inductance values from 0.2 to 2.2 microhenries. VRM designers can tailor their designs for faster transient response with the lower inductance values or lower switching losses using lower switching frequencies with the higher inductance values.

Low direct current resistance (DCR) of 0.55 to 7.0 milliohms and low alternating current loss result in lower copper losses. Inductor windings are made of rectangular copper (flat wire) wound helically, similar to a spring. Has a larger surface area than round wire for reduced skin effect loss. Also provides a self-terminating lead.

RoHS-compliant, standard footprint is 11.5 x 10.3 mm with a low profile of 4.0 mm maximum and operating temperature from -40 to +125°C.
