Concept-

The stage where an idea for a new product, a variation on an existing product, or the identification of a need for an undefined product causes research to be done to define a product, a market, and an approach for manufacturing this product.

Research-

At this stage we utilize the product concept to boost research that includes identifying the technology, methods, and vendors involved in producing the product. This stage results in a detailed design specification that is used to cost the design process that follows as well as the estimated manufactured cost of the product.

Hardware & PCB Designing-

Printed circuit boards are typically made with copper. Depending on the requirements, the copper is plated to a substrate and carved away to expose the design of the board. Since there are multiple layers, they must be lined up and bonded together for a secure fit.
The stage of PCB designing involves various process.

• Schematic Designing – Before manufacturing the PCB, we design the board which is done through computer software.Designing a printed circuit board is a detail-oriented process that brings together information from a variety of sources.
• Standard Component Selection – All the required components are selected as per the design and product requirement.
• Printing & Software Designing Of PCB – A special printer is used to print the design of the PCB. It produces a film that shows the details and layers of the board.Copper is pre-bonded to both sides of the layer and then etched away to show the design from the printed films.
• Removing Unwanted Copper – Unwanted copper that remained on the board. A chemical solution, similar to the alkaline solution, eats away at the unwanted copper.
• Inspection – The newly cleaned layers are inspected for alignment.
• Component Mounting – All the components are mounted on PCB as per design.
• Testing & Validation – Before the PCB is considered complete, a technician performs an electrical test on the board. This confirms the PCB functions and follows the original blueprint designs.Changes are done on basis of test results.

Cabinet Designing (Mechanical Process)-

• Defining the Size – Cabinet size is defined as per the size of all the components using 3-dimensional designing software.
• Prototype – A prototype is developed which undergoes inspection process.
• Assembly – Once the prototype is finalised, assembly of components is done.

Software Programming-

• Selection of controller – Controller selection is done as per the design and requirement of product.
• Flow chart – A detailed flow chart of the software is prepared.
• Software programming – Software for the design is programmed which is simulated and tested.
• Integration – A module is prepared to integrate software with hardware and this is followed by testing process.

Validation-

All the above process is tested and validated and all the trouble shooting process is followed and a final prototype is made and after final testing assembly is done along with drawing finalisation.
It consists of obtaining overall approval for a sequence of activities in order to demonstrate and provide documentary evidence that a specific product can be reliably manufactured via the processes involved.

• Specifications check-As per parameters declared.
• Details of Hardware and Software as per Bill Of Material.
• Charging &Discharging profiles.
• Solar Charging & Functioning.
• Heat & Run Test (20°C-50°C).
• Reliability Test.
