That is why we designed the MS-820 with a depth of field flexible enough to read multiple densities of barcodes on the fly without requiring additional adjustments in between product runs. Fast scan rates are especially critical in the electronics industry, because the barcodes commonly used on PCBs have very short row height. The shorter the row height, the less time the scanner has to read the entire bar code. In product tracking applications, manufacturers are relying on the scanner to verify that each board is in the right spot in the assembly process. If the history of a product is compromised at some point during the assembly process, defective boards might go undetected.
Wafers can end up in the wrong furnaces.
These mistakes can be costly. Reverse video allows the scanner to read laser-etched symbols on metalic surfaces such as silicon wafers and printed circuit boards. Microscan was an original part of AB s Intelligent Sensing line and continues to serve AB customers today by providing products that communicate with AB devices. Some of the most widely used AB data collection products are the DS and DD series decoder boxes. These decoder boxes are very robust.
