Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

In a board-to-board design using HW-36-16-F-D-255-SM, how do I check whether the 0.255" stack height matches my enclosure and connector clearance?
For HW-36-16-F-D-255-SM, verify the full mechanical stack from both PCBs, not just the nominal 0.255" stack height. The overall pin length, mating post length, solder fillet height, and any PCB thickness tolerances can change the final assembled height. In tight enclosures, it is common to prototype the stack with the intended board thickness and standoff strategy before locking the mechanical drawing.
Can HW-36-16-F-D-255-SM be used as a replacement for another Samtec 0.100" stack connector with the same 72 positions?
HW-36-16-F-D-255-SM can be a candidate replacement only if the position count, dual-row geometry, pitch, stack height, mounting style, and pin tail/post dimensions all match the existing footprint and mated board spacing. Even within Samtec families, small differences in body width, coplanarity, or solderable features can affect fit and assembly. Compare the exact footprint and mating height against the original part before qualifying it.
What PCB layout constraints should I check before choosing HW-36-16-F-D-255-SM for a high-density board-to-board interconnect?
With HW-36-16-F-D-255-SM, confirm pad geometry, courtyard, connector keepout, and assembly access around the 2-row 0.100" pitch footprint. Surface-mount stacking connectors often need controlled land pattern symmetry to reduce skew and solder imbalance. It is also worth checking whether nearby components or traces interfere with the connector body or the board-to-board insertion path.
Is HW-36-16-F-D-255-SM suitable for signals that need low contact resistance and stable long-term connection quality?
HW-36-16-F-D-255-SM uses gold on the mating contact area with a 3.00 µin finish, which is commonly chosen for repeated mating and signal integrity in compact interconnects. For long-term performance, the actual contact environment still matters: vibration, contamination, current level, and mating cycle count can all affect field reliability. If the application sees harsh exposure or frequent rework, validate the connector under real conditions rather than relying on nominal finish alone.
Can HW-36-16-F-D-255-SM be used in industrial equipment that may see vibration or shock?
HW-36-16-F-D-255-SM can be used in industrial assemblies, but the final robustness depends on the PCB support, mating board retention, and how much cantilever load the connector sees during transport or operation. Surface-mount headers are usually protected by good board stiffness and mechanical fastening between boards or chassis points. If the system is exposed to vibration, add mechanical retention and confirm that solder joints are not carrying unintended structural load.
What should I verify if I want to use HW-36-16-F-D-255-SM in a replacement design where the original connector had through-hole tails?
HW-36-16-F-D-255-SM is a surface-mount connector, so it is not a drop-in replacement for a through-hole part unless the PCB footprint and assembly process were designed for SMT from the start. Check solder paste volume, reflow profile, pad anchoring, and the ability of the board stack to withstand insertion forces without plated-hole support. In retrofit designs, the mechanical difference often matters more than the electrical pinout.
How do I confirm compatibility between HW-36-16-F-D-255-SM and another 72-pin 0.100" board connector from a different brand?
For HW-36-16-F-D-255-SM, compare the full interface package, not only the 72-position count and 2.54 mm pitch. You need to match row spacing, stack height, body outline, mating post length, and the exact SMT land pattern. Different brands may also vary in pin width, lead-in geometry, and coplanarity, which can change insertion force and assembly yield even when the pin count looks identical.
Is HW-36-16-F-D-255-SM appropriate for power distribution between boards, or should it be limited to signals?
HW-36-16-F-D-255-SM can carry power only if the current per contact, aggregate heating, and voltage drop fit the system budget. For board-to-board power, check the number of parallel pins assigned to power and return, the connector temperature rise at load, and the trace width feeding each pin. If the design carries substantial current, it is safer to validate thermal behavior with the final assembly rather than assume signal-style loading is acceptable.
What migration issues come up when replacing an older Samtec stack connector with HW-36-16-F-D-255-SM?
When migrating to HW-36-16-F-D-255-SM, the main checks are stack height, pin length, footprint compatibility, and assembly process alignment. Even if the product family is similar, changes in body height or post length can alter board spacing, and a slightly different footprint can affect solder wetting. It is also useful to confirm whether the replacement changes insertion force or board loading in the final system.
Does HW-36-16-F-D-255-SM work well for applications that may need occasional board replacement or field service?
HW-36-16-F-D-255-SM is a reasonable choice when the board stack is not meant to be disconnected frequently, because surface-mount stacking connectors are usually optimized for compactness and assembly efficiency. For field-serviceable systems, consider how accessible the mated boards are, whether alignment features are present, and whether repeated separation could stress solder joints. If service access is limited, designing in guides or fasteners can reduce handling damage during maintenance.
