Performance Test of Surface Mount Pogo Pins
Spring stroke consistency test: detects the reset accuracy after compression to the working height and release, with an error controlled within ± 0.05mm. This surface mount pogo pin can be well adapted for automated probe holder and precision module assembly.
Terminal resistance stability measurement: Under a load current of 2A, the contact resistance remains stable at <50mΩ, and the resistance change throughout the entire stroke does not exceed ± 5%. Verify the reliability of power/signal hybrid transmission.
Contact integrity test under lateral stress: Johoty’s maintains conductivity on surface mount pogo pins with ball plunger tips under a lateral force of 0.3N. Simulate the electrical continuity after PCB bending or module offset under extreme operating conditions.
Thermal shock response performance of solder pads: No welding cracking or metal fatigue after 1,000 thermal cycles at -40℃ to+85℃. The T&R packaging structure of SMT has strong stability.
Vertical compression fatigue life test: After continuous compression for 50,000 times, the elastic attenuation is less than 10%, meeting the life requirements of high-frequency signal circuits and mechanical switch modules.
Coating wear assessment (through end face SEM analysis): The area with a gold plating thickness of ≥0.1μm remains intact at >85% after 100,000 insertions and removals. The highest gold plating layer reaches 50μm, and surface mount pogo pins ensure long-term corrosion resistance and conductivity of the contact layer.
Soldering consistency test: All PIN pins have a wetting angle of less than 30° in the 245℃ ± 5℃ soldering test. Ensure consistency of end face welding during reflow soldering process.
Verification of installation height tolerance: After soldering the surface mount pogo pins, measure their total height from the PCB surface to the top, with a height difference of ≤±0.05mm within the batch. It can demonstrate excellent performance in high-speed pogo pin connector array packaging.

FAQ
What is the maximum rated current of surface mount pogo pins? In a single pogo pin structure, it typically supports a maximum continuous current of 5A (at 20℃). The pogo pin connector with multiple pin connections in parallel can expand the load path.
Does it support standard SMT process mounting? Of course, all end tail designs are compatible with industrial grade lead-free reflow soldering curves. Tail flatness <±0.05mm, suitable for fully automatic mounting lines.
How to control the consistency of plunger height after compression of surface mount pogo pins? The top height tolerance of pogo pins under full load compression state is ≤±0.05mm. It is suitable for the consistent conductivity requirements of parallel spring loaded connectors.
Will contact resistance of surface mount pogo pins increase after long-term use? After 10,000 life cycles, the contact resistance of surface mount pogo pins does not increase by more than 15%. The contact interface remains stable and is suitable for high-frequency mating systems.
Do surface mount pogo pins experience structural displacement under vibration or drop conditions? The plunger and barrel of surface mount pogo pins are designed with interference fit or embedded compression structure. After passing the IEC 60068-2-6 vibration test, there was no looseness displacement.
