Frequently Asked Questions
What contact pitch and count does the LTH-040-01-G-D-A-K support for board stacking?
The LTH-040-01-G-D-A-K provides 80 contacts at 0.5 mm pitch in a dual-row surface mount plug, making it one of the higher-density options in SAMTEC's board stacking connector lineup. Its 0.95 inch body length and 0.066 inch depth support compact PCB stack designs for portable electronics and miniaturized industrial modules.
How does the gold-plated contact finish with nickel barrier improve long-term connector performance?
The gold-plated mating contacts with a nickel (Ni) barrier on the LTH-040-01-G-D-A-K provide low contact resistance, resistance to oxidation, and protection against gold diffusion into the base material. This combination supports an 8.68-year expected service life (YTEOL), making the connector suitable for long-term embedded deployments in medical wearables, IoT modules, and industrial devices requiring reliable 80-contact, 0.5 mm pitch mating.
What role does the peg (PEG) board mounting option play during PCB assembly of the LTH-040-01-G-D-A-K?
The PEG board mounting option on the LTH-040-01-G-D-A-K inserts into PCB holes to align and retain the connector accurately during reflow soldering, preventing movement or tombstoning of the 80-contact, 0.5 mm pitch surface mount body. This mechanical stability is especially important in high-volume automated SMT lines where consistent solder joint quality across all 80 contacts at 0.5 mm pitch is required to avoid rework.
