THT-38-797-10 is a 0.375" x 0.375" Brady B-797 label: a glossy white, thermal transfer printable polyimide with a permanent acrylic adhesive, 0.0041 in. thick without the liner, wound on a 3 in. core for industrial thermal transfer printers. Brady built B-797 for printed circuit board and electronic component pre-process labeling, and its data sheet reports no visible effect after 5 minutes at 500°F (260°C) or 80 seconds at 626°F (330°C).
A board serial number only supports traceability if it can still be scanned after wash and test. B-797 is designed to withstand multiple harsh-condition PCB wash cycles, so the barcode applied at the start of the line is the same one quality, rework and field service read later. Advanced Automation pairs these circuit board labels with the printer, ribbon and software that keep that marking consistent across lines and sites.
This part is wound on a 3 in. core and prints by thermal transfer, so it runs on Brady's industrial 3 in. core printers:
B-797 is also made in B33 cartridges for the BBP33, i3300 and i5300. Those are separate part numbers; this roll does not fit a cartridge printer.
B-797 requires a ribbon, and the ribbon decides which ratings apply. Brady's UL 969 recognition (UL file MH17154) and its MIL-STD-202G Method 215K solvent result for B-797 both apply only when the label is printed with a Brady Series R6300 or R6000 Halogen Free ribbon. For non-reflow boards that go through aqueous cleaning, Brady recommends the R4900A, R6300 or R8965 series.
Match the ribbon to the printer: R6300 comes as R6300 resin ribbon for the i7100, IP-R6300 for IP Series printers and i75-R6300 for the i7500. The Ribbon Finder narrows it by printer model.
Brady's product listing gives B-797 a general service range of -94°F to 212°F (-70°C to 100°C), while its technical data sheet reports exposure results well above that. The data sheet is the better guide for process decisions:
Brady notes these are average values, not specification limits, so validate the label in your own thermal profile.
If you're qualifying a PCB label for a new line or moving several plants to one material, talk to an expert about printer, ribbon and software pairing. For recurring volume, ask about corporate and project pricing or request a quote.
For PCB and electronic component manufacturing, get labels that are engineered to survive extreme processes like wave soldering and multiple harsh washes.
