High reliability is the goal for many designers and final users of High Quality PCBs china. Since all the components are mounted on the PCB, it is expected that the PCB delivers some consistency and efficiency over time depending on the operating conditions like temperature and humidity levels. Reliability is, therefore, crucial for any PCB regardless of its use and the stage (assembly stage or manufacturing) where it is used. Consequently, it is important to determine the reliability of PCB materials through testing and through observing the data sheets provided by the manufacturer.  


  • Hole wall with copper thickness with 25 micron
Enhances the reliability of Printed circuit board company
Improves the resistance of the z-axis expansion where PTHs (Plated Through Holes) are metalized and drilled through the material thickness to form ground connections and form signals.

  • Absence of welding repairs or breaks in line repair
Adhering to these standards ensure that the circuitry is perfect hence increasing reliability and securing.
No maintenance is required since welding is done perfectly and there are no repairs needed.
Risks like electrical shock due to open circuits are eliminated.

  • Failure to adhere to IPC cleanliness specifications
The cleanliness of a PCB is improved thus its reliability increases appreciably

  • Controlling the life of treatment surface
Increases solderability since the surfaces are well treated
High reliability

  • Reduces the risk of moisture intrusion

  • Ensuring CCL tolerances adhere to IPC4101ClassB/L requirements
Controlling the thickness of the dielectric layer reduces the electrical performance’s expected deviation hence high reliability

  • Using internationally recognized base like IEE for the PCB
Improves the performance and reliability of a PCB
The calibrations are made according to an international standard hence measurements and operations can be done by an expert from any part of the world.

  • Defining the mechanical features of the PCB like holes and shapes
It enables the control of the quality of the PCB since the PCB’s dimensions can be improved making it fit to perform the required function

  • Defining solder material and ensuring compliance to the IPC-SM-840ClassT standards
Using a perfect solder material ensures that the resistivity of the solder is high hence the conductivity of the components is not affected. We at RUSHPCB ensure that we use the best solder material which is RoHS.

  • Definition of the repair and appearance requirements
Although this is not commonly defined, defining it ensures intensive care and security in the manufacturing process.

  • Solder resist layer with a thickness similar to that recommended by NCAB
Improvement in the electrical insulating properties of the PCB thus reducing the electrical resistance
Reduction of risks of flaking or the loss of adhesion.
Higher capacity to fight a mechanical force regardless of its magnitude

  • Use of peelable gums models and brands like PetersSD2955
Peelable gums can be avoided by the use of better brands. it leads to destruction of the aesthetic features of the PCB.

  • Requirements of the plug hole depth

  • Using NCAB approval procedures for each single order
