(30) The interior process chamber of BECO's Yield Enhancement Process Tanks are fabricated from a single piece of sheet material. The sheet is precision machined, and then in the Japanese "origami" method, folded into the form of a tank. This unique approach minimizes welding, and provides smooth, seamless, rounded interior corners void of traps, and leaks due to poor workmanship, thermal cycling, and chemical contact.
The tank includes weir containment for chemistry recirculation. Ports for fill and recirculation on the Yield Enhancement Tanks are located on opposing sides near the bottom providing optimum processing recirculation flow, An optional perforated diffuser plate provides for an even laminar flow through the chemical ...
(60) BECO's Yield Enhancement Quickdump Rinse Tanks are fabricated with the same "origami" style techniques as used in the Process Tanks. A single piece of sheet material is precision machined and folded to result in smooth, rounded interior corners. This provides the rinse tanks with the same construction quality benefits, and for rinsing applications, the smooth corners also improve rinsing dynamics which reduces rinsing time and water consumption.
All of the BECO Quickdump Tanks are equipped with spray manifolds that assist in preventing particle reattachment, and rinse the interior of the tank during the dumping function. The cone pattern spray nozzles are staggered from side to side and are positioned high above the tank to ...
