1A Pogo Pins

This pogo pin features gold plating on both the needle tube and shaft, with a thickness of 0.125µm. The spring's gold plating thickness is 0.025µm. This gold plating improves the pogo pin's electrical performance and environmental adaptability.

Gold is an excellent conductor, reducing contact resistance and minimizing energy loss during current transmission and signal connection. Furthermore, gold's extreme chemical stability, exhibiting virtually no reaction with oxygen or other substances, effectively prevents oxidation and corrosion of the spring pin's base material (such as brass or copper alloys), maintaining long-term stable connection reliability even in harsh environments such as humidity and acid/alkali conditions.

Abrasion resistance and mechanical durability are another significant advantage of gold plating. In applications requiring frequent insertion/removal or long-term use, the gold plating acts as a protective layer, reducing friction and wear between the needle tip and the contact surface, maintaining surface flatness and constant contact pressure, thereby extending the spring pin's lifespan and ensuring continuous connection reliability. This characteristic is particularly critical for devices requiring long insertion/removal lifespans, such as mobile devices and testing instruments.

The pogopin has a gold-plated surface, allowing it to pass a 48-hour salt spray test. The syringe diameter is 2.1mm, the needle tip diameter is 1.5mm, the overall length is 8.8mm, and it can handle a current of 1A.

Due to its small size and low current handling capabilities, this pogopin is widely applicable in products with low current requirements and those with limited internal assembly space.

The compression amount is generally designed to be 2/3 of the total stroke. This provides sufficient probe pressure while preventing impedance fluctuations caused by insufficient compression. Excessive compression can damage the orifice and cause probe malfunction.

During assembly, handle with care and avoid applying any force to the orifice. Improper force can cause deformation or damage to the orifice, resulting in poor probe reading signals and reducing the usability and accuracy of the equipment.

The battery contacts or FPC gold fingers that mate with the probe must be clean and free of stains, oxides, or other impurities.

Dongguan and the surrounding Pearl River Delta region boast one of the world's most complete electronics industry chain clusters. This allows the company convenient access to raw materials and precision parts processing services, along with a large pool of skilled workers and technical talent, resulting in rapid supply chain response and strong cost control.

As a local manufacturer, it typically possesses integrated production capabilities, from mold design, precision stamping, injection molding, and electroplating to automated assembly. This vertically integrated or deeply collaborative model helps ensure production capacity, control quality, and guarantee delivery time.

Compared to large international manufacturers, local companies have significant flexibility in terms of manufacturing costs and meeting customers' customized needs for small-batch, multi-batch production with rapid response.
