PCB Manufacturing Capabilities

pcb-manufacturer Asia Pacific Circuits

As a China PCB manufacturer for more than 17 years, we are very professional, not only in PCB fabrication but also in PCB assembly our advantages show as following:

1. Quotation for Conventional PCB within 2 hours, urgent offer within 1 hours.
2. Rich experiences in Conventional PCB manufacturing, professional suggestions from design stage in order to avoid anyimpracticable design.
3. Rich experience as PCB manufacturer enhances our understanding of oversea clients’ requests, especially requests from North America and European customers.
4. Different from other PCB manufacturer in China, we can accept sample order, small quality, series, as well as batch PCB fabrication, because we have 3 factory in China, Shenzhen plant – PCB Prototype to mid-volume PCB manufacturing and assembly services.
5. Experienced engineering team clear EQ/TQ at quick time.
6. Double check semi-finished & finished PCBs to ensure good quality.
7. Logistic department will ensure your PCBs to be delivered in quickest time and low shipping cost.

PCB Manufacturing Capabilities  – Conventional PCB


PCB Made in China


Advantages of conventional PCB

  1. Simple Via models.
  2. Low Cost (until layers count comes too high).
  3. Simple dielectrics—Primarily FR4.
  4. High reliability (until layer count becomes too high).
  5. Mature process, everybody does it. eg. 4 layers pcb, 6 layers pcb manufacturers in China. But the HDI circuit board is difficult, for the majority of Chinese PCB manufacturing factory. We have a HDI PCB plant – Changsha, China PCB factory – HDI PCB Production Quantities.

Disadvantages of conventional PCB

  1. Fewer China PCB manufacturers can obtain good yields, costs skyrocket.
  2. Via has to be large, reducing route-ability, increasing layers.
  3. Difficult to implement for BGA pin-pitches below 0.25mm.
  4. Through hole vias capacitively couple to every plane layer and signal losses increase with thickness.
  5. Long via stubs create impedance mismatches, reflections on single-ended nets.
  6. Large via pads often force diff pairs to be split under BGAs.
