What is TST-107-03-L-D used for?
The TST-107-03-L-D is used as a PCB test access strip in electronic product development, in-circuit test (ICT) fixtures, and production board diagnostics. Its dual-row 2.54 mm pitch layout allows flying probe and bed-of-nails test equipment to contact multiple signal nodes simultaneously, reducing test cycle time. The gold-plated mating contacts withstand repeated probe insertions without significant wear, making the part suitable for boards that require frequent functional testing during manufacturing or field maintenance.

Frequently Asked Questions
How many positions does the TST-107-03-L-D provide, and on what pitch are they arranged?
The TST-107-03-L-D provides 14 positions arranged in 2 rows on a standard 2.54 mm (0.100 inch) pitch, yielding 7 positions per row. This 1 inch body length fits standard grid PCB layouts and is compatible with 0.100 inch pitch ICT probe fixtures and ribbon cable assemblies.
What contact finish does the TST-107-03-L-D use, and how does it withstand repeated probing?
The TST-107-03-L-D uses 10 µin gold (Au) over 50 µin nickel (Ni) on mating contacts. The gold layer provides low contact resistance below 20 milliohms and resists oxidation, while the nickel barrier prevents gold diffusion. This finish is rated for at least 100 probe insertions without measurable degradation in contact performance.
In which test setups can the TST-107-03-L-D be used for production board diagnostics?
The TST-107-03-L-D is suited for bed-of-nails in-circuit test (ICT) fixtures, flying probe test stations, and manual debug probing. Its 2.54 mm pitch accepts standard 0.100 inch probe tips and pogo pins, and the through-hole anchor provides the mechanical resistance needed to withstand repeated vertical probe contact forces exceeding 100 grams.
How does the TST-107-03-L-D compare to single-row test strips for PCB space efficiency?
The dual-row layout of the TST-107-03-L-D delivers 14 test points in the same 1 inch body length that a single-row strip uses for 7 contacts, effectively halving the board area required per test point. The 0.365 inch width keeps the footprint narrow enough to fit between standard IC packages on a 0.100 inch grid without routing conflicts.
