Component packages continue to evolve into more complex designs, including ball grid arrays (BGAs) and surface mount technologies (SMTs). Cutting-edge equipment, capable of handling the removal and rework of these designs, is critical to electronics manufacturing production. Even the best rework stations currently available have their own nuances and intricacies associated with their use. The EMPF has an easy to use and very intuitive machine manufactured by DEN-ON Instruments Corporation of Japan and distributed by FocalSpot, Inc. The RD-500 rework systems are semi-automated, single axis placement and reflow stations for BGA/SMT rework. The RD series uses a high-performance three-point heating system and advanced computer control technology, designed for safe lead free and eutectic rework applications. Available in two models, the RD-500 series features a three-stage
heating system that produces up to 3kW overall thermal output, sufficient thermal capacity and control to execute precise profiles on small to large sized printed circuit boards (PCBs) up to 20" x 24".

The capabilities of the rework station allow for some of the more difficult to profile packages, such as metal shielded, ceramic, heat sink plates, plastic column BGAs and even flip chip packages. These unique profiles are obtained by the localized top and bottom hot gas heaters and the bottom area array infra-red (IR) heating system. Safe and uniform heating is provided throughout the board. The high-resolution, digital split image optics provide quick and easy parts placement, accurate to within +/-0.00098" (+/-0.025mm). This is very important for your smaller package sizes such as 0402s and 0805. Additionally, the low air flow design eliminates the need for variable flow rate adjustments. Finally, the RD-500 series features automated pick and place with feedback control of the part placement force for more accurate part placement after rework.

With only a few hours of training, an operator can gain proficiency using the onboard assisted software. Some of the software enhancements include automated profiling, job and component process parameters storage and recall, and complete process data logging and file storage.

FocalSpot, Inc. is recognized as a leader in the design and manufacture of affordable high-quality x-ray inspection, and is the distributor for DEN-ON RD-500 Series BGA/SMT Rework Stations in North/South America, Canada and Mexico.
