What do you feel makes Top-Link different from other connector manufacturers?

Top-Link did not become the leader of the Pogo Pin industry through luck, but rather through our innovating technology and quality control system. We have many exclusive machines and technologies imported from abroad. Also, all of our connectors are thoroughly inspected by dynamic force and resistance before being shipped. We are constantly improving and even built a new lab to perpetuate this.

What services does Top-Link provide? Can you elaborate on you solutions?

At Top-Link, we not only provide products, but also a one-stop solution to your ODM/OEM needs for connectors, fast chargers, antennas for wearables, as well as solutions for you PC, audio, and transportation device needs.

What are pogo pin connectors? How are they different or better than traditional connectors?

A pogo pin is a device used in electronics to establish a connection, usually temporary, between two printed circuit boards. With its name inspired by the pogo-stick, the pogo pin is usually the shape of a slender cylinder containing two sharp spring-loaded pins on each end. Pressed between two electronic circuits, the sharp points at each end of the pin establishes contact with the two circuits to close the loop and connect them. Pogo pins are a highly reliable, precise interconnect solution ideal for numerous demanding application requirements.

Top-Link’s spring loaded pogo pin is highly compliant, which means it’s designed to compress during insertion. Thus, boards can be stacked on top of each other whilst maintaining a good connection by taking advantage of the spring movement to accommodate for tolerance stack-ups, misaligned boards, errors in parallelism and flatness, and pivoting or rotating components. The spring loaded pogo pin is especially useful as compression-style board-to-board connectors used in today’s IoT devices.

What kind of devices can pogo pin connectors be used for? Do you have any examples to show the full potential of Top-Link’s connectors?

There are numerous applications for pogo pins such as for use in mobile phones, headphones, speakers, wearables, drones, medical devices, aerospace. automotive and much more. Our clients have utilized pogo pins to add rapid charging to their devices, to minimize the appearance of bulky charging cables for a more aesthetically pleasing design, to take their devices to the waterproof stage, and to minimize the size and improve durability for their devices.

When a customer approaches you for consultation, what is your process of understanding their product? What are the typical questions you would ask?

We try to first understand how our clients plan to utilize connectors and pogo pins. How will our components be applied? We then move forward to discussing the requirements and product drawings to fully understand our client’s needs. Typically questions moving forward are as follows: What is your required function? Will you be transferring currents or signals? How will you attach our connectors to your device?

What advice do you have for creators developing a device? What should they prepare before contacting solution partners like yourself?

We welcome creators to contact us at their designing stage! We have plenty of experience in a variety of technologies and would be able to offer valuable advice and suggestions as they finalize their device.

What are your go-to resources for tech information and news? Do you have any recommendations for our readers?

Currently, my go-to source is The Verge, but I also enjoy perusing search engines such as Yahoo! and Google for what’s new in tech.

Lastly, just for fun, what is your must-see recommendation for visitors to Shenzhen?

Coco Park. Located in the center of the city, Futian COCO Park is not only a popular shopping mall but also a landmark of the area. The 85,000 square meter mall has five levels with a large outdoor square in the center. There is so much more to do than just shopping because it is filled with restaurants, bars, and other entertainment.
