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 the CNC machine. The Cpk value of the sample is 0.98 ~ 1.12, and the failure rate can be controlled at 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.


what is the Spring Loaded connector of Dongguan Promax?

Pogo Connector, also called Spring Loaded Connector, Spring Connector, Electrical Contact Connector, or Connector Contact Pin. Pogo Connector consists of ≥2 Single pogo pins, Housing, or Cap if needed. Based on customers’ various requirements, of Single pogo pin, T-pin, Ball, or coaxial is also designed as the fourth part, besides the plunger, spring, and barrel. The pogo pin is assembled and then the pogo pin housing component is added to assemble the pogo connector. Pogo connector is widely used in modern electronic technology as a connection. At present, the connector is widely used in consumer electronics, health science and technology, smart cars, new energy, chip testing, and other fields. Every pogo connector is highly durability, the life cycle of 10,000~100,000 times

What is the Inner Structure of Spring Loaded Connector?

Because of customers’ different applications, different design concepts are required, including Bias Tail, Back Drilling, Ball Type, 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, and its impedance is <30mΩ. Bias Tail can greatly improve the stability of Spring Loaded Pin, the current is <3A, and its impedance is <30mΩ.1. Back Drilling can greatly save design space, suitable for minimal space design, the current is <1A,  its impedance is <200mΩ.2. The inclined plane will be closely contacted with the plunger, effectively maintaining the impedance stability, impedance < 30 mΩ, which can stabilize the large current.3. The ball will uniformly exert pressure on the plunger to ensure stable impedance and smooth sliding of the plunger.

What is Spring Loaded Connector 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
What are the designs of Spring Loaded Connector?
  • Pogo Connector, 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
  • When automatically matching equipment, such a pogo pin connector is usually praised by users
  • Space-saving
  • Because of large tolerance,  great freedom when using Pogo Connector
  • Can fast assemble, very flexible
  • Very stable performance of power supply, minimize the risks
Why is the Life Cycle of Spring Loaded Connector so long?

Influence on the service life of pogo connector factory 1: Friction and corrosion environment of pogo pin in application

  • When a pogo pin is working in the application, the opening and closing will produce friction and various corrosive substances in the working environment, and the use of the pogo pin will produce a certain loss over time.

Factor 2: Plug-out force of pogo connector in application

  • Under normal conditions, the insertion and extraction times of a pogo pin will exceed 10000 times, so the insertion and extraction force of a pogo pin is a key factor to determine the service life of the connector. But the insertion and removal force is difficult to control, a small force is easy to fall, and a large force is easy to damage. The core team of Dongguan Promax solved this problem to a large extent and increased the maximum number of pogo connector insertions and extraction to 100,000 times.

Factor 3: Resistance in the use of a pogo connector

  • Usually, the resistance of a pogo connector is determined by the material and coating. At present, most materials of pogo pins are brass, so the key to prolonging the service life of pogo pins is solid electroplating. Dongguan Promax adopts a special electroplating method so that the connector maintains a stable resistance value and prolongs the service life of the pogo connector.
What is Spring Loaded Connector Assembly of Dongguan Promax?

During process flow, we set up 5 QC workstations to ensure product quality well, and 1 IPQC to line tour each work station, thus, we can ensure incoming material well on station 02, can ensure semi-finished-goods well on station 04, can ensure preloading of single pin well on station 09, can ensure spring force, impedance and function well on station 12, can ensure product cosmetic well on station 13. So, we can ensure FPY (first pass yield) of the sample is more than 95%, ensure FPY of mass production is more than 99%, and ensure RTY (Rolled-throughput Yield) is more than 90% at Dongguan Promax

What is the Application of Spring Loaded Connector?

Like Spring Loaded Pin, Pogo Connectors are widely used in all kinds of fields, for example, consumer electronics, wireless communication equipment, 5G, new energy, POS, medical, industry, and so on. it plays various roles from power supply to equipment to 5G RF signal transmission, including:

  • TWS charging box
  • Two-In-One Laptop
  • Electric Car charging system
  • Smart Glasses, because of very small space, stable power supply transmission, high durability, long-term life cycle
  • Handheld device charger, for example, Phone, Bar code reader, Laptop
  • Warehouse Robot
  • Intelligent Speaker
  • Smart Watch, Smart bracelet
What is the packaging of Spring Loaded Connector of Dongguan Promax?

Pogo Connector Packaging: Tape & Reel, Tray, Tube, Box, PE bagDongguan Promax has several automatic packaging machines, which greatly improve the packaging speed of the pogo connector. The speed of automatic packaging machines is 5 times that of manual packaging. The use of an automatic packaging machine improves production efficiency and ensures the supply speed of Dongguan Promax.
