  1. Small-sized, highly integrated devices are mass-produced, resulting in smaller and smaller wire spacing, thinner and thinner insulating films, resulting in lower breakdown voltages (lowest breakdown voltage may be <20V). )

 

  1. The electrostatic voltage generated by the prototype pcb manufacturing electronic product during production, transportation, storage and transfer far exceeds its breakdown voltage threshold, which may cause breakdown or failure of the device and affect the technical specifications of the product.

 

The damage form to electronic products by static electricity . The basic physical properties of static electricity are attraction or repulsion, a potential difference from the earth, and a discharge current will be generated.

 

The effects of these three characteristics on electronic components are as follows.

  1. Electrostatic adsorption of dust, reducing component insulation resistance (short life)
  2. Electrostatic discharge damage, so that the components are damaged and cannot work (complete destruction)
  3. The heat generated by an electrostatic discharge electric field or current causes the component to be injured (potential damage).
  4. The electromagnetic field generated by electrostatic discharge is very large (several hundred V/m), and the spectrum is extremely wide (tens to several dry MHz), causing interference or even damage to electronic products of prototype pcb manufacturing (electromagnetic interference).
