Automatic tape setting apparatus
A component package tape is transported to a pitch feed mechanism section by a tape transport device and is held in a first tape holding section by a tape holding releasing device. Furthermore, a top tape adhered to a carrier tape that is transported to the pitch feed mechanism section is peeled from the carrier tape by a top tape peeling section while being clamped at a leading end section, is transferred to a top tape delivery mechanism section, and is held in a second tape holding section by the tape holding releasing device.
PROCESSING SYSTEM AND DEVICE MANUFACTURING METHOD
A processing system and a device manufacturing method that can perform manufacturing of an electronic device without stopping the entire manufacturing system, even when the processing state actually implemented on a sheet substrate by a processing device differs from the target processing state. A processing system for sequentially conveying a long, flexible sheet substrate along a length direction to each of a first through a third processing device to form a predetermined pattern on the sheet substrate, wherein the first through the third processing devices implement a predetermined process relating to the sheet substrate according to setting conditions set to each processing device, and when at least one from among the states of the actual processing implemented on the sheet substrate by each of the first through the third processing devices exhibits a processing error relative to a target processing state, changes other setting conditions, separate from the setting conditions exhibiting the processing error, according to the processing error.
