For a good TWS headset, the key functional indicators are Bluetooth connection, sound quality, noise reduction, battery life and intelligence. Because earphones are often exposed to sweat, mainstream TWS earphones use glue and three-proof paint to solve the problem of internal and external waterproofing, so that users can get a better experience.
Common glue locations include
1. Dispensing glue on the plastic cover of the earphone shell, recommends Dongxin 10:1AB glue, which has high bonding strength, anti-drop, and salt spray corrosion resistance.
2. For the solder joint protection of the inner wire head of the earphone, Dongxin UV glue is recommended, which can cure quickly in 3 seconds, resist falling, and resist salt spray corrosion.
3. The charging stand is fixed by magnet bonding. Dongxin quick-drying adhesive is recommended, which has fast curing, firm bonding and anti-vibration and impact.
4. For component protection of battery protection board, we recommend Dongxin UV glue UV536 series products, with low viscosity, high transparency and fast curing. UV536 is a one-part, UV-curable, acrylate-based adhesive. This product is specially designed for general bonding of ABS plastic, metal, aluminum alloy, glass and other materials. It has the characteristics of good adhesion, good toughness, strong earthquake resistance and good weather resistance, and the glue has a certain thixotropy, which is very helpful for construction. Under the irradiation of UV light, it can be quickly cured in a few seconds, and it is suitable for assembly line operations. Application industry: electronic scales, placement lenses, micro speakers, smart switches, etc.
5. For the waterproof protection of the circuit board of the charging stand, Dongxin polyurethane three-proof paint series is recommended, with good adhesion. Its main features are:
Adjustable viscosity for easy operation
Strong adhesion, flexible adhesive layer after curing
5% acidic NH4Cl, 5% alkaline Na2CO3 immersion test for 24h
Compliant with ROSH REACH requirements
With fluorescent indicator for easy inspection
Application industry: new energy, digital electronics, 3C products, medical equipment, rail transit.
