The press-fit termination means it seats into a plated through-hole backplane without solder — the interference fit holds the pin and makes the electrical connection simultaneously. A mating guide feature on the header aligns the connector pair during blind-mate insertion — common in backplane card cages where the operator can't see the engagement point. ## What the 20 + 8 Layout Means for Your Board The 28 positions are not all the same — 20 are signal contacts and 8 are power blades. The signal pins handle lower-current logic or data lines, while the thicker power blades carry the main DC rail. This hybrid layout saves board space compared to separate signal and power connectors, but it means the PCB footprint must accommodate two different hole sizes and trace widths. The power blades typically need wider traces and heavier copper pours on the board to handle the bus-level current the series is rated for. ## Press-Fit Termination — No Solder, No Rework Headaches The interference between the pin and the hole wall cold-welds the joint — no solder paste, no wave, no reflow. That makes it attractive for backplane assemblies where rework on a multi-layer board is costly. The trade-off is that the PCB hole diameter tolerance is tighter than for a soldered pin; the board fabricator needs the specified finished hole size to get the right press-in force.","metaTitle":"TE MINIPAK HDL 1-1892786-1, 28 Position Header, Press-Fit","metaDescription":"TE Connectivity MINIPAK HDL 1-1892786-1 header, 28 positions (20 signal, 8 power), press-fit, right-angle, UL94 V-0.
