Checker 101E uses patterns to detect and inspect parts, for reliability. Offers the simplicity and power of the original, plus it directly accepts encoder signals, eliminating the need for a PLC when tracking and rejecting parts on variable-speed production lines.
 
“The simple-to-use Checker 101 sensor radically changed the way sensor users detect parts or part features, eliminating the complex wiring, mounting, ladder logic programming, and precise part handling required when using multiple photoelectric sensors,” said Brian Phillips, VP, expert sensors. “By directly accepting encoder signals, the Checker 101E eliminates the cost and complexity of a PLC for part tracking and rejection on variable-speed lines. Unlike the shift register of a PLC, which requires programming, Checker’s shift register is automatic, enabling it to accurately track up to 4,000 parts between the inspection and rejection point.”
 
Acquires and processes over 500 images/sec., can detect and inspect parts on fast production lines. If inspection is not required, it can detect and track parts or webs for improved process control.

Crysta-Apex C1600/2000 Series coordinate measuring machines (CMMs) handle measurement of large auto body and airframe assemblies and similarly sized components.
 
The large, bridge-type machines incorporate four-loop control to reduce cost and maintain accuracy.  The low acquisition cost makes it feasible to bring CMM capabilities to inspect large workpieces used in the manufacture of heavy equipment, marine construction, automotive powertrain, etc.   
 
The multi-sensor system uses high-speed, non-contacting digitizing probes (two- or three-axis) and a variety of scanning, vision or conventional touch probe inputs.  When equipped with the SP80 long stylus (max 500 mm), it is capable of deep hole measurement.  System software compensates for temperature and surface variations to ensure quality data acquisition under varying conditions.

SolderStar will use Nepcon Shanghai to launch three easy-to-use thermal profiling packages, designed for the technical and budgetary requirements of low, medium and high volume Pb-free electronics manufacturing environments – SolderStar Lite, SolderStar Plus and SolderStar Pro. Visit booth 2J25-9 at the exhibit.
 
The range is lead-free compliant and fulfills the need for fast, precise profiling and process control. Typically, clients can achieve an optimal thermal profile after 30 min. and perhaps two or three runs through the reflow oven.
 
Incorporating up-to-date battery technology, the instruments are said to have a higher working temperature than most alternatives, and they incorporate heat shielding, which keeps them cool even at higher processing temperatures. Measure just 20 to 25 mm thick. This makes them ideal for use in modern reflow ovens with limited tunnel height, typically used in the manufacture of miniaturised products, such as mobile phones.

 
SolderStar Lite works for the small manufacturer or as an entry-level or second system. It includes four-channel Neptune datalogger, a Pb-free capable heat-barrier and a standard software suite including a solderpaste thermal profile library, and analysis and control capabilities.
 
SolderStar Plus offers a six-channel Neptune datalogger with a high-performance heat barrier, and simulation software for ultra-fast profile set-up.
 
SolderStar Pro includes the Neptune SL datalogger with up to 12 channels for demanding processes and PCBs, as well as full-feature software that includes SPC capabilities. It can be used with accessories to optimize wave soldering processes and profiles, and is ideal for medium to large manufacturers who profile continuously as part of an ongoing quality control strategy.

DEK has developed processes for depositing silver epoxy and B-stage adhesives for die attach applications, for higher throughput and repeatability as well as enhanced control over deposit characteristics including total thickness variation (TTV).
 
The process for B-stage epoxy deposition allows application of die attach adhesive at the wafer level, at high rates of throughput. This streamlines package assembly and also allows OEMs to outsource this process to a wafer specialist. The process can deposit a part-cured adhesive layer of nominal thickness 50 micron, with TTV less than ±5 micron, across the back side of the wafer.
 
For attaching singulated die to a lead-frame or bond pad, the process replaces dispensing to deposit silver-loaded wet epoxy ahead of die attach. Many hundreds of deposits can be made simultaneously, so epoxy deposition can match the speed of die placement. Die placement rates are 40,000 units/hr., with SMT pick-and-place technology.
 
“Mass imaging delivers the throughput, uniformity and repeatability that commercial producers of advanced semiconductor packages need in order to economically meet market demands for quality and price,” said Clive Ashmore, Global Applied Process Engineer at DEK. “For die attach using B-stage or wet epoxy adhesives, our mass imaging processes outgun legacy techniques in every respect, to deliver a more highly optimized, faster, more repeatable and more cost-effective solution.”
