Production lines of Spring Loaded Pins and Spring Loaded pin Connectors are conducted in dust-free workshops. When the plunger pin, locking pin, and spring are assembled, the impedance is tested by an automatic spring impedance tester. 

This will be followed by CCD, aligner, manual pressure, crimping, and full inspection. A spring loaded pin has multiple testing steps to ensure that each pogo pin is of high quality.

How about our products’ Cpk?

We obtained this Complex Process Capability index by analyzing the size data of sample NC4891, and used this to evaluate the precision of CNC machine. The cpk value of the sample is 0.98 ~ 1.12, and the failure rate can be controlled in 0.5 ‰ ~ 0.9 ‰. There are only 5 ~ 9 bad products in ten thousand products. Dongguan Promax has mastered the complete quality control system and is working towards Cpk1.33.

Gage R&R (ANOVA) for Press Fit

This GR & R analyzed 100 pressure data of the press fit. Through 10 different products, three technicians were asked to test the press fit to evaluate the overall performance of the reproducibility and repeatability of the press fit.

FAQ

What is pogo pin?

Spring loaded pin is an electrical connector structure used in modern electronics applications. They are more durable than other electrical connectors. The name spring loaded pogo pin comes from the pin’s resemblance to a pogo stick – the integrated helical spring in the pin applies a constant normal force against the back of the mating receptacle or contact plate, counteracting any unwanted movement which might otherwise cause an intermittent connection.

What is pogo pin's inner structure?

A basic spring loaded pin consists of 3 main parts: a spring loaded plunger pin, spring loaded locking pin, and a spring. Because of customers’ different applications, different design concepts are required, including Bias Tail, Back Drilling, Ball, T-pin type, or Coaxial. Of 4 designs, designs of T-pin/Ball/Coaxial can meet the requirement of high current, up to 15A or upper, its resistance is <30mΩ. Bias Tail can greatly improve the stability of Spring Loaded Pin, the current is <3A, and resistance is <30mΩ.  Back Drilling can greatly save design space, suitable for minimal space design, the current is <1A,  resistance is <200mΩ.

What is Pogo Pins' Working Status?
  • Free Height:   is no load height, full extension height of spring
  • Working Height:  is the ideal load height for spring
  • Maximum Load Height: is the maximum load height of the spring, usually, contacting the end of the barrel
Pogo Pins' Designs
  • Spring loaded pin, because barb on the barrel, very stable after mounting onto the housing
  • Stopper on the bottom of Spring Loaded Pin, very strong fix into housing too
  • IIn the range of ±10°, no dropping for the Spring Loaded Pin life cycle, but, when the angle is 15°, the life cycle will drop accordingly
Pogo Pins' Life Cycles
  • At Dongguan Proma, the Spring loaded pin life cycle is in the range of 10,000 to 100,000 times
  • Mechanical life cycle:  maximum working times to ensure spring force in spec
  • Electrical life cycle: maximum working times to ensure contact resistance in spec
