What are the key features of TFM-145-04-STL-D-LC?
- 90-position dual-row configuration at 0.050 inch (1.27 mm) pitch delivers ultra-high-density board-to-board signal connectivity within a compact SMT footprint
- Surface-mount tail (STL) termination enables reflow-solderable assembly at up to 260°C, eliminating PCB through-hole drilling and reducing fabrication cost
- Low-clearance (LC) profile achieves mated board-to-board stack height under 5 mm, enabling tight mezzanine and module-on-carrier stack-up designs
What is TFM-145-04-STL-D-LC used for?
The TFM-145-04-STL-D-LC is engineered for ultra-high-density board-to-board interconnect in FPGA mezzanine cards, high-speed memory interfaces, and multi-lane signal routing applications in telecommunications and high-performance computing. Its 90-position dual-row SMT layout supports parallel bus widths exceeding 64 bits, making it a strong fit for processor module-to-carrier card connections. The low-clearance profile and SMT termination simplify assembly in compact product enclosures where both board separation and PCB layer count must be minimized.

Frequently Asked Questions
What is the maximum signal density that TFM-145-04-STL-D-LC provides in a board-to-board interface?
TFM-145-04-STL-D-LC provides 90 signal positions across a dual-row SMT footprint at 0.050 inch (1.27 mm) pitch, achieving a connection density of approximately 40 positions per inch. This high channel count supports parallel interfaces such as 64-bit memory buses, multi-lane LVDS links, or combined power-and-signal bus structures on a single connector body without requiring adjacent connector stacking.
How does TFM-145-04-STL-D-LC integrate into an automated SMT reflow assembly line?
TFM-145-04-STL-D-LC uses surface-mount tail (STL) termination pads compatible with standard SMT stencil printing and reflow soldering at peak temperatures up to 260°C (per J-STD-020 MSL guidelines). The 90-position body can be placed by pick-and-place equipment, and its stable SMT footprint at 0.050 inch pitch allows fine-pitch solder paste deposition without bridging, reducing manual touch-up compared to through-hole connectors in high-volume PCB assembly.
For a 90-pin parallel bus, when is TFM-145-04-STL-D-LC a more practical choice than two 45-position connectors?
Using a single TFM-145-04-STL-D-LC instead of two 45-position connectors eliminates the alignment tolerance stack-up that occurs when two separate connectors define the mating interface for a 90-pin bus. A single 90-position connector guarantees all 90 signal paths mate simultaneously with uniform 0.050 inch pitch contact spacing, reducing impedance discontinuities on differential pairs and eliminating the 0.2 mm to 0.5 mm positional variation that can occur between adjacent dual-connector footprints.
