Tyco Electronics has a new high-current Card Edge connector based on its SEC-II product line. The power connectors are said to increase the current carrying capacity by over 70% compared to traditional card edge connectors. The increased ampacity comes from a triple beam power contact, which increases the cross sectional area of the contact yet maintains the same mating force and contact wipe as the SEC-II signal contacts.
 
Carries up to 25 Amps per contact and is available in a variety of combinations of power and signal contacts combined in a single molded housing.  
 
Available with three mounting options:
*PCB tails for soldering to plated through-holes
*Compliant press-fit PCB tails
*Straddle/surface-mount PCB tails for co-planar applications
 
Are suited for traditional Voltage Regulator Module (VRM) applications.

Kester will provide lead-free resources, technologies and products during Nepcon China this week.
 
The company will feature numerous products from its Lead-Free Solutions (products and services) portfolio to help companies beat the July 1, 2006 RoHS Directive deadline. Featured products are EnviroMark 907 lead-free no-clean paste and its low-cost Ultrapure K100 lead-free bar solder alloy, along with  technical services to help manufacturers assemble lead-free. 
 
EM907 reportedly exceeds customers’ expectations for high-yield Pb-free manufacturing, and was designed for the higher thermal demands of assembling with higher melting temperature Pb-free alloys. Featuring a long stencil life, the solder paste is said to offer Pb-free joints that closely resemble those achieved with Sn/Pb solder paste.
 
K100 is a near-eutectic tin/copper alloy with controlled metallic dopants to control the grain structure within the solder joint. This improves joint reliability and virtually eliminates common defects such as icicling and bridging. The improved grain structure also results in completely filled and shinier solder joints than traditional lead-free alloy alternatives.

EMA Design Automation has integrated Omnify software into the EMA EDM environment, increasing capabilities to make adherence to RoHS/WEEE compliance directives even easier. “Omnify is a proven technology for managing data,” said Manny Marcano, president and CEO of EMA. “Integrating it into our EDM solution provides five key capabilities that bolster our compliance by design philosophy, allowing companies of any size to have the power of a full EDM system.”
 
The capabilities include:

Configuration Management
Manages data and controls revision levels on the customer’s entire product.
 
Bill of Materials (BOM) Management
Manages all revisions and understands the lifecycle of a BOM. Since the BOM items link directly to active part data, customers can analyze and generate compliance reports from any level or from any version of their BOMs.
 
Document Management
Provides document versioning/vaulting on all documents associated to product or vendor records. Changes made to documents are performed under a user-defined and controlled process.
 
Change Management
Changes made to product data usually require validation by all affected parties. Provides a controlled change management process that allows users to define product and documentation changes and allow them to vote on suggested changes. Handles the automatic routing to users (via email) and updating of product records when there are changes to products (part replacements, AVL changes, part number changes, availability, etc.). These changes must be captured and performed in an automated fashion.
 
Enhanced Reporting
Customers can generate reports from any level of the product structure. Can automate the generation and packaging of these reports. Since EDM captures data during product development, these reports can be generated, products can be analyzed and adjustments can be made at design time.

DesignAdvance Systems announced the latest release of  CircuitSpace, its user-assisted PCB component placement software.
 
This version expands on the tool’s hierarchical approach to PCB design through enhanced auto-clustering and replication technologies. Can expedite the design process by expanding on its capabilities in the areas of template libraries, automatic bypass capacitor assignments, double-sided board placement and intelligent channel and/or port duplication.
 
“Having seen unsuccessful attempts, I was skeptical of any company claiming to have a product that automates component placement. My opinion on the subject changed since I started using CircuitSpace,” said Mark Dills, 20+ year veteran of the PCB business and a Senior PCB Designer with SofTEQ. “The auto-clustering and replication features alone can save hours, days, even weeks of time off of a design cycle.”
 
This release adds features to address the challenges associated with managing frequent board design modifications.
 
The tool guides users through the concurrent board design by:
    * Automatically identifying changes to a board design as they arrive through successive netlist imports
    * Producing addendum clusters for newly added parts
    * Assessing the impact of design changes on component placement and reporting part loss or gain and part type changes
    * Reporting on detailed changes from current board design, to quickly adapt to the new requirements and to facilitate feedback to the hardware engineer

Photo Stencil aquired the AMTX E-Blade electroformed squeegee blade from Xerox. It is said to improve printdeposition, quality, uniformity and consistency. With a rigid, low-friction, hard-nickel edge, the blade provides cleaner prints, reduced stencil wear and less material waste.

 
"The electroformed E-Blade demonstrated the lowest squeegee pressure of any other squeegee blade I have tested for both SMT and wafer bumping printing," said Rick Lathrop, technical service manager of surface-mount materials at Heraeus. Heraeus recently completed a study on squeegee blades. "With lower print pressures come all of the benefits of reduced understencil wiping frequency and increased stencil life. The lack of paste scooping in large apertures for wafer bumping can only enhance bump coplanarity for automotive and WLCSP applications."

 
The blade also addresses issues caused by Pb-free printing. Pb-free solder paste requires higher squeegee pressures for a clean wipe of the stencil. The E-Blade prints at 33% of the squeegee pressure of other popular squeegee blades. High squeegee pressures result in "smear mode" printing whereas low squeegee pressure allows "sheer mode" printing.

Tyco Electronics’ Global Application Tooling Division (GATD) has collaboratively worked with Graphic Solutions International (GSI) to provide them with an RFID Inlay assembly system. This equipment will assemble semiconductor chips, surface-mount devices and printed batteries onto a continuous web of printed antennas, adding RFID capability to tags and labels.

 
Working closely with GSI, Tyco provided a reel to reel system that allows GSI to mount flip-chips, SMDs and printed batteries on a continuous web of printed antennas and conductive traces. The system is capable of the high-speed mounting of electronic components on a 6,000'+ (1,800+ m) roll of 20" wide material. After conductive printing, the roll is fed into the Tyco machine where components are added along with one or two printed batteries. Upon completion, the roll can be slit into individual streams and rolled, or supplied in production web width rolls for delivery. A typical circuit is inlaid with batteries, an RFID chip and a printed antenna. Its speed allows for production levels up to 26 million inlays per year.
 
The continuous web assembly system produces inlays that offer performance improvements over conventional PCBs. The system allows mounting flip chips for almost any purpose, as well as the ability to mount most standard SMDs along with GSI’s printed batteries. Can mount on paper, PET or other flexible substrates, and features a variable width capability up to 20" wide. Can accommodate printed substrates from 0.002" to 0.005" thick, mount on continuous rolls with a repeat pitch of 0.8" and position chips to micron accuracy.
