Applicable scenarios

Scenarios such as micro speaker voice coil manufacturing, Bluetooth headset voice coil assembly, car audio cable fixation, and high-end speaker substrate reinforcement solve core problems such as insufficient accuracy of voice coil paint removal, loose bonding and disconnection, and sound quality distortion (global market share of 70%+, technology ranks at the world's leading level).

Core products and technical solutions

Product Category	Technical parameters and application details	Adapt to core equipment/processes
Voice Coil Stripper (BT-101A/B)	Adjustable viscosity (500-1500mPa・s), dedicated to grade 180 E-line paint removal; The paint is peeled uniformly and without residue, and does not damage the voice coil substrate; It is suitable for continuous operation of the assembly line, and the paint removal time is 4-8 seconds	Micro speakers, headphone voice coils are soldered pre-treatment
SV glue / ICOK glue	SV glue: Improves voice coil strength by 20%, vibration response error ≤± 0.5dB; ICOK adhesive: vibration resistant, anti-wire breaking, curing time ≤ 30 minutes; Temperature resistance range - 20°C~220°C	Voice coil enameled wire modified bonding, wire head fixation, adapted to mobile phone/car audio
Voice coil substrate coating adhesive	35% increased mechanical strength, with a temperature resistance limit of 300°C; Improved voice coil frequency response (20Hz-20kHz full coverage) and reduced distortion rate	The voice coil substrate of high-end speakers is strengthened to adapt to high-power sound scenarios

The core advantages of the solution

1. Leading technology: The core paint stripping and bonding technology is world-class, accurately adapting to the high-precision requirements of voice coil manufacturing;

2. Sound quality optimization: improve the vibration consistency of the voice coil through material modification to ensure the clarity and stability of sound pronunciation;

3. Flexible adaptation: viscosity and curing speed can be customized to meet the differences in production processes of different manufacturers;

4. Batch compatibility: Adapt to automated voice coil production lines to improve mass production efficiency and product consistency.

The application value of the scheme

1. The defective rate of voice coil manufacturing is reduced to less than 0.2%, and the distortion rate of sound quality is reduced by 15%-20%;

2. The service life of the voice coil is extended to more than 3000 hours, suitable for high-frequency and high-power working scenarios;

3. Help customers create high-end electro-acoustic products and enhance market competitiveness.
