SMT screen printing specialist, Speedprint Technologies, launched a sophisticated barcode traceability package integrated into its SP710 printer platform at APEX 2017 in San Diego. The new S-Track system is an industry first and unique in featuring pick & place technology inside a screen printer. S-Track places barcode labels on boards while still in the printer – introducing the benefits of traceability earlier, one process step upstream from the placement machine, and right at the start of surface mount assembly.
S-Track deploys a label feeder within the printer’s architecture to allow an unlimited number of pre-printed barcode labels to be positioned on the board in an unlimited number of locations. It is an industry first. The S-Track package provides automated barcode reading and includes the company’s Traceability Option software, allowing users to scan barcodes to recall all the process data related to that board – including those once part of a panelized PCB.
The proven label feeder technology, used widely in the component placement sector, provides the same functionality and operational convenience found in pick & place machines, with quick-change nozzles for different label styles and sizes, and precise positioning for location accuracy. Labels can be oriented through 90 degrees to fit around PCB features.
For panelized PCBs, S-Track users can affix a label to each board in the panel and take advantage of incremental indexing of barcode data to distinguish and track each board after depaneling further downstream. This enables complete end-to-end traceability across an SMT assembly line.
Taking traceability automation further, S-Track scans barcodes directly after placement and saves that data to the SPC database. Any label that fails to read accurately is immediately replaced. S-Track’s high-speed scanning head can read 1D, 2D, and laser-etched barcodes markings.
The S-Track placement head mounts alongside the company’s Advanced Dispense Unit (ADu), renowned for its ability to dispense solder paste and adhesive. With S-Track added to the ADu module, the SP710 machine allows users to print the board, pick and place the barcode label, dispense additional solder paste and adhesive if necessary, and then scan all the labels on the board. Operators can store all the process data and even capture images of 2D failures for future review. This functionally and flexibility make S-Track completely unique. No other screen printer features label placement technology to give traceability right from the start of SMT assembly.
