pcba processing attaches great importance to ESD protection
At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If the PCB factory is determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and the PCB factory can get the opportunity to develop again.
   There are many precision electronic components on pcba board, and many components are sensitive to voltage. Shocks higher than the rated voltage will damage these components. PCBs damaged by static electricity are difficult to investigate step by step during functional testing. What's more deadly is that some pcba boards function normally during the test, but when the finished product is used in the hands of the customer, there are occasional defects, which brings great hidden dangers to the after-sales service and affects the company's brand and goodwill. Therefore, in the PCB processing process, we must attach great importance to ESD protection.
  
  The method of strictly controlling ESD protection in PCB processing is as follows:
  
   Ensure that the temperature and humidity of the workshop are within the standard range, 22-28 degrees Celsius, and humidity 40%-70%
  
  All employees must discharge static electricity when entering and leaving the workshop
  
   Dress as required, wear an electrostatic cap, an electrostatic clothing, and an electrostatic shoe
  
  All stations that need to touch the pcba board must wear a rope static ring, and connect the rope static ring to the static alarm
  
  The static wire is separated from the equipment ground wire to prevent the equipment from leaking electricity and cause damage to the pcba board

  In strict accordance with ISO quality management requirements for ESD static inspection
  
   Static electricity is invisible and intangible during the production process, and it is out of the ordinary, often inadvertently causing fatal hidden dangers to pcba circuit boards, and the cost of pcba troubleshooting is very high. Therefore, each factory manager must strictly pay attention to ESD static management, so that the pcba processing process can get complete quality control.
