Methodology

During the complete electronic product design cycle,  Zenso’s design and development team respect a strict development methodology in order to minimize risk, reduce cost and deliver outstanding design and quality. In the consecutive design steps we take into account the different boundary conditions as specified by the customer to guarantee a perfect integration into the final product. Each step results into a tangible delivery allowing the customer to closely follow up progress and interact with the design and development team on concrete matter. Depending on the design task our methodology is embedded into an ISO9001 compliant process for industrial and consumer electronics and into an ISO13485 compliant process for medical design tasks. Zenso’s methodology is modular. Or the customer steps-in at a discrete phase, according to status and needs of the project or Zenso manages the project from idea till finalized and integrated product and manages the production of the integrated system.

The feasibility study is an important step in the development of a turnkey solution. The aim is to translate customer requirements agreed upon at the project definition stage into one or more conceptual designs in which boundary conditions, critical design paths and key hardware components are explored. In essence, it evaluates through a proof of concept the technical and economical feasibility of the requested design task and defines in more detail the system requirements based on user, functional, performance, safety, regulatory, … specifications.

Starting from selected hardware components (sensors, controller, mechanical components, data storage, communication interfaces, …), and simulations, electronic system design encompasses following tasks:

  • analogue, digital and mixed signal design
  • schematic design
  • PCB layout design (rigid, flex, flex-rigid)
  • unit & system testing
  • PCB assembly 

Along with the PCB design, the software architecture is designed accordingly:

  • Hardware abstraction layer
  • Embedded software
  • PC based software (GUI)
  • Maintenance and testing SW 
  • Production software

The mechanical design phase assures a seamless integration of the electronic components into the housing. This can be an existing housing foreseen by the customer, or a newly designed housing. In the latter, Zenso can interface with the customer's own design house or in case of SPOC (single point of contact) principle Zenso can manage the industrial design with a preferred partner. Zenso's electronic CAD system integrates smoothly with mechanical CAD programs.

Testing and validation is an essential part in all steps of the design process. Testing and validation intermits end-to-end with the design process to assure quality and design reliability with respect to the system requirements. Testing and validation spans the whole range from unit testing to functional and performance testing, safety and regulatory testing requirements, …including inhouse testing as well as testing by certified labs.

Pre-production prepares production tools and processes. It defines quality inspection tests and functional verification testplans for PCB or system production. In case Zenso takes care of the production of the fully integrated system this phase foresees in corresponding mechanical production and assembly tools and test platform. This phase results in a process flow for the production and assembly of the system.

After the verification phase and certification against regulatory requirements, the design and validation reports are closed and transferred to the customer along with a certified product. According to the customer preferred way of working, the production can be initiated under full control of Zenso, or the production can abe handed-over to the customer own production facilities or to a preferred production partner.

Zenso can deliver different production services according to the customer preferred way of working. This can be in house production and assembly of the complete system where Zenso acts as the single point of contact and takes full responsibility over the end-2-end production process ie managing manufactures, integrating parts, quality inspection, dispatching, …. Another option is to support the customer during the due diligence phase for the selection of an appropriate manufacture and hand-over the full production or part of the production towards a preferred manufacturer.
