Customer Reviews
We are very satisfied wtih you guys. Quick response, professional engineering team, fast delivery, good quality... all are nice. I am sure we can have much more business in the future.

—— Kevin Kinder

End customers were satisfied with the quality, so did I for the past years. Have recommended you to my other friends that have needs in PCBA.

—— Mariusz Sharp

Thanks for help my small business grows up step by step,for prototypes to small, medium & large orders, you will be my first choice for PCB anytime.

—— Adam Burridge

Good price, fast lead and delivery time, shipping cost is quite good! Our company is satisfied with your good service for the last 4 years!

—— Luboš Herceghová

Hello good afternoon. I received the 80 pcs PCB. Thank you. I like so much that. That is good qualtiy, nice color. Pls take care of the remaining 80 pcs PCB. Thank you. Have a nice day. :)

SMT PCB Assembly

  • High Precision SMT PCB Assembly suppliers
  • High Precision SMT PCB Assembly suppliers


SMT PCB Assembly means Surface Mount Technology, known as a a kind of Circuit assembly technology that installs the SMC/SMD (named Chip Components in Chinese) on the surface of Printed Circuit Board or on the surface of other substrates, which is solded and assembled by means of reflow soldering or dip soldering. It realizes high density, high reliability, miniaturization and low cost of electronic product assembly.



1. High density, small size, low weight;

2. Reliable, strong earthquake resistance and low defect rate of soldering spot;

3. High frequency, reducting the interference of electromagnetism and radio frequency;

4. Easy to realize automation and improve production efficiency.

3.PCB Manufacturing Process


  1. 1.1 Step 1 – The Design.
  2. 1.2 Step 2 – Printing the Design.
  3. 1.3 Step 3 – Creating the Substrate.
  4. 1.4 Step 4 – Printing the Inner Layers.
  5. 1.5 Step 5 – Ultraviolet Light.
  6. 1.6 Step 6 – Removing Unwanted Copper.
  7. 1.7 Step 7 – Inspection.
  8. 1.8 Step 8 – Laminating the Layers.


4.The PCB Fabrication Process


  • Imaging desired layout on copper clad laminates
  • Etching or removing excess copper from inner layers to reveal traces and pads
  • Creating the PCB layer stackup by laminating (heating and pressing) board materials at high temperatures
  • Drilling holes for mounting holes, through hole pins and vias
  • Etching or removing excess copper from the surface layer(s) to reveal traces and pads
  • Plating pin holes and via holes
  • Adding protective coating to surface or solder masking
  • Silkscreen printing reference and polarity indicators, logos or other markings on the surface
  • Optionally, a finish may be added to copper areas of surface
