Featuring ProfitPro, an Excel-based software application that calculates the cost and profit related to PWB assembly, the SMTA Cost Estimating Guidelines are intended to model real-time cost estimating (RTCE) in the electronics industry. The guidelines are arranged by Dr. Ronald C. Lasky, Indium Corp. of America/Dartmouth College.
Using these production variables such as cycle time, hours/shift, shifts/day, days/week, set up time and dowtime, ProfitPro can model RTCE for high-volume, low-mix to low-volume, high-mix lines. Has default values of unknown cost metrics, can calculate "what-if" scenarios, including:
- The amount of profit gained if setup time is reduced.
- The amount of profit gained if cycle time is decreased.
- The amount of profit gained if new equipment or materials increases productivity.

National Physical Laboratory has developed a new instrument for measuring solder properties. The advent of lead-free alloys makes it imperative to obtain accurate material properties on volumes of materials under 1mm^3. Instruments must be able to measure and displace small distances, typically a few micrometers to a precision of 0.1µm, and to measure low forces.
NPL has developed a machine that achieves this capability. Measurements are now possible at typical stresses and strains found in solder joints, resulting in realistic fatigue and creep rates. These values are essential for accurate, statistically based life-time predictions of lead-free reliability.

The RFID Smart Feeder system can be retrofitted to an existing placement machine in the field. The customer's inventory of feeders can be converted into "Smart" feeders by attaching a low-cost RF tag to each feeder.
Key features:
- Enables closed-loop feeder and component setup validation
- Eliminates human errors and reduces changeover time
- Provides real-time material inventory and traceability
- Quick and easy retrofit on any machine type
- Proactively scans all feeder slots in real time.
Can be used in combination with Cogiscan software applications. Can be integrated with feeder set-up verification software from third-party suppliers to eliminate manual barcode scanning at the machine.
