common problem:
1. Appearance defects
2. The buttons are not sensitive
3. The light flashes
4. Always on
5. Unable to work
6. Unable to charge
7. Short use time and less frequent smoking
8. The amount of smoke is small and unstable.
9. Surface fogging and oxidation
main reason:
1. Appearance defects:
- Poor hardware plating, such as plating peeling off
- The hardware is scratched, resulting in scratches
- Battery tube rubber paint peeling or peeling
- The battery tube is scratched
2. The buttons are not sensitive:
- The buttons on the circuit board are not elastic enough, resulting in poor feel.
- Production and assembly problems, the buttons and brackets are not well connected, loose and fall off
- The connection between the button and the bracket is loose due to falling or vibration
- After process improvements, such as adding card slots to the hardware body to fix the buttons and brackets, or ensuring that the elasticity of the buttons on the solution board meets reasonable requirements, there may still be uncontrollable reasons.
3. The light flashes and stays on:
- The indicator light on the circuit board flashes, mainly because the MOS tube is burned out by static electricity from the human body during the assembly process, disrupting the program board program and causing the circuit board to fail to work properly.
- Each worker is equipped with an electrostatic ring to guide static electricity underground to reduce damage to circuit boards, but there are still uncontrollable problems.
4. Unable to work:
- Assembly problems, such as poor contact between the positive and negative terminals of the battery or the wires on the solution board being broken
- Battery is dead and needs to be charged
5. Unable to charge:
- The battery cell is exhausted, the voltage is zero, and it cannot be charged.
- The battery pole or USB cable is damaged and cannot be charged.
- Poor contact between battery pole, USB cable or charger
- Therefore, the circuit board should have a low-voltage protection function and stop working when the cell voltage drops to 3.2V to avoid complete discharge.
6. Short use time and less frequent smoking:
- Battery core quality problems, such as B-grade batteries, have large internal resistance, resulting in reduced use time and number of cigarettes.
7. The amount of smoke is small and unstable:
- Battery core quality problems, such as B-grade batteries, the voltage is unstable, the lower the output voltage, the smaller the amount of smoke
8. Surface fogging and oxidation:
- Battery core quality problems, such as B-grade battery leakage and internal material seeping out, causing white mist to appear on the surface and metal corrosion
In summary:
Appearance problems: Mainly related to hardware, battery tubes and buttons
Intrinsic quality: Mainly related to batteries and solution boards
Common influencing factors: employee professionalism and assembly quality have an impact on internal and external quality.
