PCB Design and Layout


PCB Layout design process generally starts with Circuit Schematics that have been captured using a Schematic

Capture package like Altium, PADS Allegro. Such a package will provide the requisite Schematics and Net-List

files. 


In case you have not entered your circuit diagram into a popular schematic capture software, but have it 

available hand-drawn on paper or as graphic file, then the Layout designers will capture the schematics on a 

Schematic capture package.

 

We layout the most complex circuits with up to 40 layers or high-performance designs for DDR3. With

professionality and competence our engineers advise our customers regarding appropriate base materials,

structures, regulations and practical board designs for specific applications. The PCB layout team is a key

interface between customer, R&D, production and PCB manufacturer – here all comes together.


KINGRON designers master the dissolution of complex digital and analog circuits as well as PCB designs of any

complexity and technology:

 

 Strengths and services of our PCB Layout team:

>Multilayers with more than 40 layers

>Rigid, flexible and rigid-flex PCBs

>Optimized component placement (3D data generation and collision check)

>EMC-optimized and impedance checked layout

>Thermal management

>Provision of norm compliant production documents and documentation

>High-performance designs for standards like PCIe, DDR3, HDMI, LVDS, etc.


Our highly qualified layout team works with the most advanced layout tools and designs amongst 

others most complex FPGA and high-speed layouts in the field of image processing, probe cards for 

Automated Test Equipment (ATE) for the semiconductor industry and flexible circuit boards for the medical

field.


PCB Manufacture


We choose A+ grade copperplate to ensure stable performance (general FR-4) of PCB fabrication. During the PCB 

manufacturing process, automatic copper plating lines and high-speed drilling machines to make accuracy and fast 

delivery guaranteed. All printed circuit board will be detected by advanced automatic flying probe machines

(or test fixture ) at subsequent stages to make sure each PCB is OK from inner circuits to outside shape. 

With the initial stage of PCB design, timing is always very crucial.
