Performance Test of Pogo-Pin
Contact impedance test: The 4-wire method is used to measure the contact resistance of a single pogo-pin, with a typical value of 20~30mΩ and a maximum of 50mΩ. It has high signal integrity and low loss transmission, meeting the requirements of high-frequency and low-voltage applications.
Elastic range test: The loading displacement of pogo-pin is controlled within the working stroke (≥0.10.6mm), corresponding to a measured elastic range of ≥ 5gf, with a tolerance control of ±15%. It can verify the reliability of crimping and the consistency of rebound performance.
Life fatigue test: Automatic reciprocating loading of 1Hz, typical life test reaches 10,000~30,000 times without needle dropping, without plunger broking. Johoty monitors impedance changes within ± 20% of the initial value, which confirms long-term stability.
High temperature resistance: Hot air aging test at 125℃/48 hours, we will record the changes in contact impedance and elasticity before and after the test. Evaluate the stability of structural component materials and the adhesion of electroplating layers.
Salt spray test: Neutral salt spray test for 24-96 hours, we will observe the corrosion status of the coating. Analyze the anti-oxidation ability of pogo-pin by combining the glossiness of the end face and impedance changes. Ensure that every pogo-pin can adapt to the design requirements of harsh environmental conditions.
Welding reliability test: Reflow temperature curve with a peak value of 260℃, verified by pad wettability and solder paste compatibility. Ensure contact consistency and controllable yield after SMT assembly.
Appearance and dimensional tolerance testing: The high magnification imaging system screens each pogo-pin flat bottom without warping, plunger concentricity, and barrel length within ± 0.05mm. Ensure SMT mounting accuracy and stable mechanical fit.

FAQ
Does Pogo-pin support high-density mounting with a center distance of 0.4~0.5mm?
Support. The outer diameter of the barrel can be controlled within ≤0.50mm, with a layout accuracy of ±0.02mm. It meets the requirements of compact design such as FPC, small module, and precision probe holder.
What are the evaluation criteria for lifespan testing?
Perform reciprocating fatigue experiments at a loading frequency of 1Hz. The impedance fluctuation within the working stroke shall not exceed the initial value ±20%, and the effective life interval shall be defined. The common lifespan can reach 10,000 to 30,000 cycles. Johoty’s special design can achieve a lifespan of 200,000.
Can pogo-pin specify a combination of plunger tip shape and elasticity?
Sure. There are 20 types of plunger tips to choose from, including ball head, concave point, and blade, etc. Adapt to different structural contact surfaces and compression loads with customized elasticity range (5gf~500gf).
Can pogo-pin maintain plunger height stability after reflow soldering?
Controllable. The rear of barrel adopts a flat bottom design and is woven with vacuum feeding tape, making it less prone to warping and collapsing after welding. After cooling at room temperature, the height drift of pogo-pin is less than ± 0.05mm.
Is pogo-pin mixed with different heights and electroplating layers?
support. Pogo-pin can be configured with spring needles with different needle length, elasticity and surface treatment in the same module. Meet the interface requirements of some customers for multiple signals, currents, and operating conditions.
