Analysis of technical difficulties of TWS earphone pogopin
The pogo pin inside the TWS Bluetooth headset is mainly used to link Bluetooth, touch the motherboard, link the LDS antenna, inductive touch, and so on.
1. PogoPin environment testing
TWS earphones have special requirements for the electroplating of PogoPin pogo pins in terms of hand sweat, electrolysis, and electrified corrosion.
• The specific test conditions of each TWS earphone brand will be slightly different, and even the same test conditions, different test methods, or different electrolytes may produce different test results.
• Sweat Type: 1. Conventional Sweat Test ISO3160-2 (7 components); 2. Pickering Sweat (33 components)
2. PogoPin mirror turning technology
"Mirror turning" adopts high-precision CNC lathes, and uses finely researched diamond turning tools to turn products at high speed, so that the surface of the products can be as bright as a mirror, and extremely sharp tools are used to perform micro-cuts on the product for many times so that the workpiece reaches high Dimensional accuracy and smoothness can also be called "superfinishing".
