Products for SMT Assembly Traceability
December 31, 1969 |Estimated reading time: 5 minutes
Traceability in the electronics manufacturing facility generally requires extensive labeling and the associated readers to track components, PCBs, subassemblies, and other parts as they move from inventory to the factory floor and into other processes like final assembly and inspection. These new products from Microscan, Adhesive Applications, Keyence, Taiyo America, and Trumpf increase visibility and tracking at the manufacturer.
Handheld ImagerThe point-and-shoot Mobile Hawk handheld imager quickly reads any 2D barcode, including direct part marks (DPM). It is capable of reading challenging, low-contrast direct part marks. DPMs are typically 2D Data Matrix symbols permanently marked by methods such as dot peen or laser/chemical etch onto substrates. These marking methods often result in low contrast visibility of the symbol or inconsistent imprints that can be challenging to decode through traditional imaging technology. The Mobile Hawk combines proprietary MAXlite machine vision illumination with aggressive X-Mode DPM algorithms. MAXlite leverages NERLITE machine vision lighting with an integrated, optimized multi-axis lighting solution. From simple high contrast linear barcodes to low-contrast or damaged 2D symbols, the Mobile Hawk reads all marks quickly and reliably with a simple pull of the trigger. It can be powered by USB from a single cable connection, eliminating external power supply. The Mobile Hawk also features a blue line targeting pattern for quick symbol location, and easy barcode output into standard databases. Microscan, www.microscan.com.
Acrylic Transfer Adhesive TapesThis expanded line of acrylic transfer PSAs provides a superior solution for a number of applications, including specialty labels, membrane switch assembly, automotive, appliance, laminations, and more. This new line of acrylic transfer PSAs will be sold as full width logs, with customer-specific modifications as needed. They are available in a variety of coat weights, mil thicknesses, pigmented colors, and liner options. All of these products adhere to PSTC and ASTM test guidelines and are UL recognized for marking and labeling NT100 and NT140. New products include the 600 Series with high shear, moderate LSE, and high temp shear; 800 Series for a lower cost high-peel high-tack application; 900 Series for low temperature applications; 200 GFR Series, a glass-filled tape with high shear and high cohesive strength (clear or red); and the 900 GFR Series glass-filled for low-temperature applications (clear of red).

Laser Marking StationThe TruMark 5000 NEW laser marking station follows the first generation of the TruMark Series 5000 product line with longer traverse paths and higher travel speeds in the linear axes, which are available as a complete module that can be installed by hand in just a few steps; a more powerful suction unit that enables marking processes with strong materials removal; and enhanced ergonomics. The TruMark 5000 NEW has a Z-axis travel path that is 200 mm longer than the TruMark 5000’s. Now 19.6″ (500 mm) long, the traverse path offers flexibility in marking larger components in a variety of sizes. In addition, the laser system can be equipped with two linear axes (300 mm) and a rotating axis. The linear axes control concept with an integrated motor driver eases the task of retrofitting the workstation. The travel speeds of the X and Y axes are 3× faster. The axes can be correctly positioned manually with the push of a button. During the process of marking many parts, emissions are produced during material removal. The stronger suction unit takes into account the increased laser outputs of the marking lasers in the TruMark Series 3000, 5000 and 6000, all of which can be integrated into the workstation. Access to the workstation has been improved, simplifying work preparation and the loading and unloading of parts. Users can program how wide the door should open to reduce time between loading and unloading. The workstation can be operated either from a sitting or a standing position. All of the sensors from the laser and workstation can be maintained and supported remotely using Telediagnostics. TRUMPF, www.us.trumpf.com.
Compact Digital Barcode ReaderThe KEYENCE BL-1300 ultra-compact digital bar code reader uses parallel digital processing technology. Noise reduction and compensation functions overcome the reading performance difficulties of conventional analog circuits. Constructed with die-cast magnesium bodies, the IP-65 rated readers are highly resistant to dirt and harsh environments, and are easily mounted. The High-speed Parallel Processing Engine (HPPE) allows for stable performance of up to 1,300 scans and decodes per second. The BL-1300 Series provide nearly 100× the information processing capacity and have a high-speed motor 2.6× faster than previous models. Its aspherical lens doubles the intensity of the received laser reflection, reducing noise and increasing the effective label reading distance. An edge detection process accurately extracts the points of alternation between bars and spaces. 3Hi-Digital models can solve typical reading problems such as non-uniform line thicknesses, misaligned marking, shiny backgrounds, uneven backgrounds, reading from a diagonal orientation (pitch angle), etc. High-resolution digital processing reads codes printed as low as 0.08 mm (0.003″) without noise interference. Test modes can be initiated by using the test switch built into the barcode reader body. The 5-bar LED quickly shows results. The BL-1300 Series supports USB and Ethernet interfaces while continuing to support RS-232C, RS-422A and RS-485 communication. The Multi-I/O function allows users to assign various operational functions to the reader’s 2 inputs and 4 outputs, which can be configured to match application conditions. Additional functions include Auto-Trigger Mode, Preset/Comparison Function, Barcode Position Detection Function, Synthesized Barcode Reading Function, and support for GS1 Databar (RSS) Barcodes.

Photoimageable Legend InksS-200W thermal-cure and PSR-4100WL (HD) photoimageable legend inks are certified to CID A-A-56032, “Commercial Item Description — Ink, Marking, Epoxy Base,” the predominant marking ink specification for military PCBs. Qualified for military applications, the white legend ink products are made in the U.S. and are available as quickly as overnight. TAIYO AMERICA, INC., a subsidiary of Taiyo Ink Mfg. Co. ltd., www.taiyo-america.com.
Fiber Laser MarkerTruMark 5020 fiber laser marker, from the TruMark Series 5000, suits marking applications on metals and plastics with high speed and excellent edge quality requirements, thanks to the high pulse frequencies and pulse-to-pulse stability. The TruMark 5020’s highly dynamic scanner module is able to convert pulse frequencies of up to 1 megahertz into a correspondingly high processing speed. Master Oscillator Fiber Power Amplifier (MOFPA) technology, the pulse duration of the TruMark 5020 can be adjusted to adapt laser processing to the application. A focal point adjustment ensures that the laser’s focus point adjusts to the different component heights. For laser safety, the machine includes a tough fiber protection hose and a mechanical lock that prevents the laser beam from discharging between marking procedures. Scanner, laser head and power supply unit are connected via plug-in connectors allowing the modular marking laser to be integrated into existing production systems. In addition, Telediagnostics makes it possible to maintain the fiber marking laser remotely. For this purpose, the TruMark 5020 comes with integrated laser power measurement and laser power calibration. TRUMPF, www.us.trumpf.com.
