Frequently Asked Questions
What contact count and pitch does the QTH-040-01-H-D-DP-A use for board stacking?
The QTH-040-01-H-D-DP-A features 80 contacts in a dual-row female configuration on a 0.50 mm pitch, delivering 40 contacts per row for high-density board-to-board stacking in space-constrained PCB designs.
What gold plating thickness is used on QTH-040-01-H-D-DP-A contacts and why does it matter?
The mating contacts are plated with 30 µin (0.76 µm) of gold over a nickel barrier, providing excellent corrosion resistance and low contact resistance over many mating cycles. This finish ensures reliable signal transmission in high-cycle test fixtures and applications requiring consistent contact performance over a rated life exceeding 100 insertion cycles.
How does the DP-A peg option improve PCB assembly with QTH-040-01-H-D-DP-A?
The DP-A dual-peg option adds two plastic retention pegs that insert into PCB mounting holes, securing the 80-contact connector during soldering and preventing movement under the 0.50 mm pitch SMT reflow process. This reduces tombstoning risk and eliminates the need for fixtures during automated board assembly.
