Multicore LF328 is a halide-free, no-clean, lead-free solder paste designed for high-volume stencil printing applications with CSP lead pitches of 0.5 mm and 0.4 mm. As lead-free manufacturing becomes the norm, the ability to reliably process finer pitched devices within Pb-free parameters will be vital.
Is formulated to deliver low voiding in BGA joints. Said to offer performance over a range of reflow profiles and long abandon time capabilities, the paste gives assemblers the flexibility they require when running lead-free processes. The material provides tack force to resist component movement during high-speed placement, allows a fast print speed with low print pressure to minimize board warpage and offers humidity resistance. Soldering activity on a range of surface finishes including Ni/Au, Immersion Sn, Immersion Ag and OSP copper enables lead-free production.
Produces safe residues, which eliminate the need for cleaning, and its post-reflow low-color residues simplify visual inspection .
The latest revision of Cadstar Express is the easy to use free Web download of the desktop PCB design solution, Cadstar. This fully functional version of Cadstar 8.0 features tools for design from schematics to manufacture, with a limit of 300 pins and 50 components.
Improved functionality includes developments in schematic design and library management, lead-free component technology and jumpers.
Users can also view samples of the 140,000 component on-line component library, Cadstar Exchange. This Web-based source currently contains components from 17 manufacturers including Intel, National Semiconductors, Philips, ST Microelectronics and Xilinx and is part of the maintenance agreement.
Includes a Do-It-Yourself manual in PDF, with tutorials and video files to illustrate key features.
Series 1522 Inflow Dust Containment Cabinets are available in a variety of sizes and styles, with a painted steel finish compatible with typical cleanroom environments. They provide an effective solution for mailroom protection, hazardous materials and biosafety applications.
Feature an acrylic hood for durability and long life, with minimal required maintenance. Custom options are available upon request.
The system draws air into wall-mounted filters where it is filtered and discharged back into the workspace. The HEPA system consists of two parts: the absolute HEPA filter and a flexible duct to form a modular component. HEPA filters meet Mil Standard 282 and are tested for leakage for 99.99% removal of all particulate contaminants greater than 0.3 micron.
Before the HEPA filter there are two stages of prefiltering, the second of which can be an optional charcoal filter. The prefilter is made of disposable, non-woven framed fiberglass media, with a nominal efficiency of 40%.
