SRT Introduces the Summit LX Series advanced rework systems for large PCBs

Designed "from the ground up" specifically for reworking large format boards and backplanes, the Summit LX Series, new from Sierra Research & Technology (SRT; Westford, MA), is up to the task in size and capacity. Two models, the Summit 1100LX semi-automated rework system and the Summit 2100LX automated rework system, are the industry's most advanced, yet easy-to-use component removal and replacement systems for SMT components.

The new Summit LX Series is optimized for larger PCBs assemblies up to 24-in by 36-in. Features include user-friendly controls, high energy heating capacity and greater bottom area coverage, an enlarged frame and board support table, motorized top heater Z-axis, and enhanced optics. The Summit LX Series is capable of removing and replacing BGAs and CCGAs, small chip scale packages (CSPs), flip chip, and fine pitch components. It is also ideally suited for high volume production rework.

Large PCBs and SMT components require careful under-board heating. The Summit LX Series' high efficiency, gas bottom heater plenum provides 8.0 kW of energy, uniformly distributed across a 24-in by 36-in area to prevent warping of large PCB surface areas. The enlarged frame and board support table are designed to handle a board weight of up to 80 lb. Precision ergonomic controls on the Summit 1100LX table, and the fully motorized Summit 2100LX table simplify alignment and eliminate the need to rotate the board to rework different areas. The easily configured board holder provides a 2.75-in top side and 2-in bottom clearance, and can be removed and replaced with custom pallets or fixtures. Motorized Z-axis adjustment on the Summit 1100LX and Summit 2100LX assures precise site location and also helps access the component without concern of surrounding obstructions.

Specially designed for the Summit XL Series, an enhanced vision system makes it easy to place components and connectors up to 80mm. An automatic prism shuttle mirrors the component and the substrate together in the microscope, providing a composite alignment view. Split mirror provides 50% more viewing area, enabling the operator to see bumps, leads or pads on large devices at high magnification

The Summit LX Series uses the company's SierraMate graphical interface for Windows. The repair operator simply selects the board type, the component to be reworked and operation to be performed, then hits "Go." The system completes the reworking of each board/component combination according to preset parameters. In addition, the Summit 2100LX combines rework with fully automated, non-contact site scavenging.

Both the Summit 1100LX and the Summit 2100LX are equipped with programmable high/low air flow and incorporate SRT's "Auto Profile" capability, which automatically develops the correct time/temperature profile for any assembly, mirroring the original manufacturing process. Profile settings can be stored for fast, repeatable operation.

Customer shipments of the Summit 1100LX and the Summit 1200LX are scheduled to begin during the fourth quarter of 2000. Delivery is four to eight weeks ARO. Trade-ins, financing and lease-to-own packages are available. Pricing and upgrade information is available by contacting the company.

SRT offers a complete line of semi-automated and automated rework systems for the electronics assembly industry.
