Printed Circuit Board Design
Doxals, one of the leading technological companies based in Singapore, boasts of an excellent track record in the specialized area of Printed Circuit Board (PCB) design.
What is PCB?
PCB or printed circuit board provides a base for housing and connecting electronic components by means of conductive tracks, pads and other features. The components, such as capacitors, resistors and other active devices are affixed to the PCB by means of soldering. In certain other cases, the components may be embedded in the substrate.
PCB Design
Doxals distinguishes itself by its sound engineering methodology that offers efficient and cost-effective designs. Using PCB design software, Doxals engineers undertake PCB layout and design most efficiently.
Steps in PCB design
Doxals uses dedicated layout software to complete PCB design in the following steps:
● Step 1: Using an electronic design automation tool for schematic capture.
● Step 2: Deciding the card dimensions and template on the basis of required circuitry and case of the PCB.
● Step 3: Determining the positions of the component and heat sinks.
● Step 4: Deciding the layer stack of the PCB.
● Step 5: Determining line impedance using dielectric layer thickness, routing copper thickness and trace-width.
● Step 6: Placing of the components.
● Step 7: Routing of signal traces.
● Step 8: Generating Gerber files for manufacturing.
Circuit schematic capture
The capturing of the schematic for the circuit is achieved in a variety of ways. Circuits that are entered into a schematic capture tool may either form part of the PCB design suite or constitute an external package with exportable output in a suitable format. Simulations of the circuit may be undertaken at this stage.
Once the schematic capture is complete, the electronic design of the circuit is then converted into a ‘netlist’, which is nothing but interconnectivity information.
PCB component placement
A rough idea of where the components will be placed is essential before undertaking detailed PCB design and layout. This will highlight the requirements, such as space needed for the required circuitry and the number of layers needed in the board.
After the rough estimate, a more detailed component layout is made for the PCB design that takes into account aspects, such as the proximity of devices and RF considerations. All components incorporated into the PCB must have all the relevant information, so that they can easily be called up when required.
Routing
Routing the physical connections between all the components, according to the netlist from the schematic, is achieved by using a number of layers made available for connections. Routing for larger designs may take substantial amount of computing power, not to mention significant amount of time.
PCB files
The information for the photo plots of the PCB layout are obtained in the form of Gerber files. In addition, drill information is also generated along with the screen print and photo-resist information. Drilling is crucial and may prove costly if different sized holes are to be drilled.
Conclusion
Doxals has proved itself to be one of the leading PCB designers. Their flawless designing and use of superior materials make the customers return for more.
