3-D engineering models for all DEK printer subassemblies can now be downloaded over the Internet, allowing machine owners to examine components in detail without taking a machine offline, and to verify and order new parts or upgrades quickly and easily.
 
The 3-D Find-a-Part service is free to all DEK machine owners, and is accessible 24/7 via the secure technical support account pages at www.dek.com.
 
Models are the actual CAD models used by DEK engineers, and are accurate, fully detailed and up to date. Customers can rotate the models in three axes, measure dimensions, zoom in or zoom out, isolate and inspect individual sub-components, and find part numbers using context sensitive keys. Price and availability, as well as online ordering, are also supported.
 
Because of the large file size for each model, DEK has installed extra, dedicated Internet infrastructure to support the service, so customers can view any model on screen in the time it takes to download the file.
 
“This service is valuable for customers needing to quickly inspect any subassembly or optional unit, such as a print head or underscreen cleaner, and also streamlines ordering of replacement or upgrade parts,” said Jon Howell, Customer Service Group manager. “As well as providing a more powerful troubleshooting solution than hard copy general assembly drawings, customers no longer have to spend time describing a required component to DEK sales or support staff. Examining a component and finding the part number now requires just a few simple mouse clicks.”

Adding to its series of recently introduced optimized material sets, Henkel has announced a materials combination designed for stacked CSP (SCSP) devices. Uniting die attach material Hysol QMI536NB with mold compound Hysol GR9820, this material set reportedly delivers JEDEC Level 1/260° reflow performance.
 
Both materials perform well in Pb-free environments, with a high resistance to elevated temperatures and demanding manufacturing conditions. GR9820 is a versatile epoxy molding compound with adhesion properties that can be optimized for varying leadframe metallizations. The low-stress, “green” mold compound exhibits ultra low warpage in a matrix package format, with the ability to alter the mold compound resin components to counter-correct “smiling face” or “crying face” warpage in a range of package types.
 
QMI536NB is one-material solution for thin stacked die applications. Traditionally, different die attach materials are used for each of the various layers of a stacked package so as to avoid damage to the die passivation of the first die. This protective and low-bleed formulation can be used for both mother and daughter die, enabling packaging specialists to qualify a single material.

Eunil H.A. Americas has added the PARMI SPI 3-D paste inspection system to its product line.

The in-line solder paste inspection system reportedly provides reliable, accurate, 100% inspection at high speeds. Inspects numerous kinds of solder paste defects after screen printing by measuring height, area and volume in conjunction with the system’s fast and accurate 3-D data.

Can detect printing faults (volume, height, area, registration, bridge) and monitor the printing process, which helps the operator find the printing status quickly on the line. Uses SPC, providing printing process monitoring and control both on- and off-line.

Increases first pass yield by preventing faulty PCBs from going through the next process. Prevents in-circuit test and outdoor failure, provides control of the printing process.

440-R SMT Detergent is available in a ready-to-use spray bottle for safe, effective manual cleaning of SMT stencils and related tooling.  The stencil-cleaning chemistry  is verified for specific parameters of environmental safety, user safety and cleaning efficiency by the U.S. EPA’s Environmental Technology Verification Program. 
While ultrasonic technology is effective for removing solder paste from SMT stencils, manual cleaning continues to be common. Stencil cleaning has been identified as the most hazardous process with the greatest potential environmental impact associated with SMT assembly.  Flammable and VOC solvents such as alcohol and acetone are commonly used for manual cleaning and poisonous heavy metals such as lead often come in contact with the user.  This safe water-soluble detergent cleans effectively, improves print production and eliminates noxious odors and hazards associated with solvent cleaning.
