PCB DESIGN

Have an Innovative Idea which can be the next big global product ? Have a concept that can create a great product but lack design skills ?
Explain the design in layman's language and receive tested prototype along with complete design documents for mass production.
We offer extensive design services including design, cost estimation, prototyping and also mass production.

Confused about your new Design? What are the important points to be considered while designing a new PCB ?
Design should be Cost efficient with appropriate choice of components.
Design should be Manufacturable ie. efficient for mass production.
Design should be Testing efficient.
Design should consider ease of Assembly.
Design should be provide Reliability for long term use.

Is PCB layout important ?
Layout can have a large impact on performance.  Poor layout can introduce large parasitic L, R, and C.  You're circuit may oscillate, even though it is meant to be an amplifier!

Which Software should i use to make my schematic ?
We support most popular Schematic formats namely Altium DXP, Protel, PADS, PCAD, Allegro, Orcad and CircuitMaker 2000. However this is NOT a limitation, you may also provide a schematic in PDF or JPG format or simply a picture of a handmade sketch!

I have an existing product, can i make modifications or functionality changes ?
Yes, Provide details about changes required (like wireless logging, remote control, PC connection/control etc) and we shall get to you within 48 working hours with all the required details.

I have an idea for a new revolutionary product, can I protect my design ?
Yes, if you worried about your design, we sign NDA (Non Disclosure Agreement) before you pass the information to us. We also have advanced techniques to protect the product from being cloned.

If I design a New PCB what production files shall I receive ?
We provide Altium DXP PCB file and Gerber files (both can be used for PCB production)
Apart from this we also provide with 3D layout pictures to give better Idea of PCB.

PCB design and layout planning is as important as that of electronic circuit itself for the electrical, mechanical and thermal performance of the complete system.


A typical multi-layer PCB is designed and expected to maintain signal integrity and power integrity as per requirements. However, parasitic resistances, capacitances and inductances provide less than ideal conditions for power and well as signal. As a result, a number of rules are needed to be followed to maintain signal and power integrity as follows,

  • PCB traces are mostly made of copper that carries a finite resistance. Though it is neglected in the digital systems, precision analog systems may be severely affected by voltage drop at that resistance as a result of current flow, resulting in degraded accuracy. So, controlled impedance traces are needed for that part of circuit for high accuracy.

  • Resistance of traces results in temperature rise as substantial current flows. As a result, the width of traces is needed to be increased. If width increase is not possible due to circuit density, then the copper thickness of board (commonly 1 oz) is needed to be increased to 2 or 3 oz depending on requirement, to lower the operating temperature of PCB hence improving its reliability and life.

  • Stray inductances of the traces result in voltage spikes and can be improved by adding sufficient decoupling capacitors near the active load (like IC or controller)

  • Since current passing through a trace generates magnetic field around it. This magnetic field may disturb the performance of nearby active components. To avoid this, one way is to increase the distance between the components, but mostly it is not possible. Another way is either to route return path along with the trace or add a ground plane. A ground plane acts like a shield and provides return path of any signal in the signal layer. Ground planes provide good decoupling in multi-layer PCBs.

  • Ground planes are preferred to be separate for analog and digital portion of a circuit, and it is recommended to connect them at a single point only.

  •  90 degree traces should be avoided due to EMI issues.

  • Traces carrying analog signals should not run long track along with digital ones. Crossing both signal at one point is a good practice to avoid noise coupling.
