You have an idea for an electronic product, the following should - to have the device, music or video system saving time, or the biggest device solving a problem which was ever invented? Even if you have examination of the project of a product of electronics in stock, there are many problems which you should finish and problems which you should solve before you will have an actual project of a product which can be made, sold, and is sold. As soon as you have finished the document of the specification of a product and marketing research, you should be prepared to have product electronics, and the packing project processes begun so that pre-production model unit could be collected and checked up.
One of the first elections which should be made in electronics project, - what microprocessor or architecture of the microdispatcher will be used, if your idea of a product demands ability of processing. The majority of the microprocessor or devices of the microdispatcher are accessible in set of configurations of the internal sizes of memory with a few, including non-volatile memory of Flash to storage of the program, quantity and types of pins of an input and an exit, types of a package for superficial fastening or statements through an aperture, speeds of hours, and interfaces which are supported by the processor, not having necessity to add additional devices.
Once the microprocessor or a family of the microdispatcher is selected, additional decisions should be accepted, on which frequency of hours of system to use, how many the processor and memory of system will be required for the statement and as processes of working out of the software should be supported. The choice of architecture of the processor should consider accessible working out of the software and tools of testing and resources of the project of the software which will be required for the project of program maintenance / the programmed equipment of your product. Additional decisions should be accepted on how program maintenance / the programmed equipment will be loaded into memory of the processor during production. The project will allow a finished article to accept area, or the user has begun modernisations of program maintenance / the programmed equipment, or the product will be disposable programmed unit?
Before the part of the processor of the project is finished, you should define also, what types of interfaces to external systems will be required (a serial port, parallel port, USB, Ethernet, a wireless communication such as 802.11x or Bluetooth, infra-red, etc.) and the minimum demanded norms of a pass-band of the interface. All these factors will play a role in a choice of the best product of the processor to use in your statement of the project.
Some examples of a product of the microprocessor/microdispatcher which you can investigate, a number of the FRIEND of the Microchip and a family of products from Atmel as both from these suppliers provide some very strong, but cheap decisions for the processor is.
Electronic components, including microprocessors and microdispatchers, are typically accessible both in superficial fastening and in versions through an aperture. Some electronic components can be accessible only in one format (such as some transformers, the relay, condensers, power resistors, or the connectors which are accessible only in packages through an aperture). Superficial components of fastening are preferred for any uniform manufacture of volume as they are usually less expensive to buy, with bolshej readiness accessible, and to consider more compact projects of board of the printed circuit as components take much less places and can be applied to both parties of board in case of need.
Using superficial fastening the technology presumes to use to the project of board of the printed circuit the smaller size and-or less layers, thus reducing crude expenses of board. However, superficial components of fastening can make internal meeting and spaivanie difficult, if not impossible if you do not have appropriate equipment and examination.
The finished project will include section of power supplies which will provide pressure and the current levels demanded by components of the project. Entrance variants of the power could include unit inclusion in 120 exits VAC, and transformation of pressure AC to the corresponding has adjusted levels of pressure DC internally as a part of the project of power supplies. You could also wish to use the external adapter of the power which transforms 120 VAC to level of pressure DC and then regulates this arriving level of pressure DC to the level demanded according to the project. To the third choice would consist in putting a product in action batteries. If your product be the battery put in action, in addition to definition of technology of the battery and number amp hours of storage of the power per batteries, you should consider also, whether is better the recharged project of the battery or the end user zamenimyj the project of the battery for the product and estimation statement.
As soon as the project of electronics and the project of board of the printed circuit are finished, mechanical packing and external projects of an investment can be finished, and initial working out of the software can be finished. Now has come to collect time unit of a pre-production model both checked up, and decisions should be accepted concerning manufacture of initial units of a pre-production model.
Elections include the order of all components and assemblage of an internal product of a pre-production model if you have a meeting examination, concluding the subcontract contract on process prototyping to internal firm-manufacturer of electronics of the contract, or concluding the subcontract contract on process prototyping to the firm-manufacturer of electronics of the contract located from coast. If you do not have examination or the equipment properly to collect pre-production model units, you should prepare the list of the companies which can support yours prototyping and requirements of manufacture and to begin process of identification of your best variants.
In addition to identification who will collect pre-production model units, you should identify also, you will use what choice for manufacture of units of manufacture. Elections include manufacture of units independently, the conclusion of the contract of meeting of units outwardly with servants, or the conclusion of the contract of meeting of units with from coastal electronics the industrial supplier of service.
If you plan to use an external industrial source, to believe, that some companies specialise at low meetings of a speciality of volume, such as units of a pre-production model or initial manufacture, but not in a condition is profitable to support levels of production of great volume because of full restrictions. Other companies are in an opposite spectrum and specialise only in levels of great volume. The quantity of units which would be manufacture of great volume from your point of view, probably, is not big enough to reveal any interest strictly manufacturer of great volume. You should consider also terms of delivery from the receipt of your order for delivery as the factor in a choice of an external source of meeting.
Other important factor to consider in this process of an estimation of electronics, industrial suppliers of service would be the help of the project with which they can be able provide during product development. Services, such as the project of electronics and the project of an arrangement of board of the printed circuit, making process of a choice and acquisition with the help in multi-sourcing components, the investment project, the mechanical packing project, and maintenance of ability of manufacture from prototyping to low volume by the great volume could have all the huge help to you. Besides, the manufacturer of electronics of the contract can provide also offers to improve manufacturability, to lower making expenses, and to improve reliability of a product. Be convinced, that had the corresponding Nondisclosure agreement in a place with any and all parties, which are involved in this process to protect your intellectual property.
You should define also how will be, the made product should be checked up and packed. As soon as the product was prototyped and ested it is successful, important to define quantity of units which will be made for initial manufacture which industrial levels operate and for volume. You should understand also, how many levels of distribution the product passes (with each level taking reduction of edges) before it will reach before the consumer to buy.
If you are an inventor or have the big electronic idea of a product, I do not wish to interfere with you, but you should consider all these actions and their connected expenses before you will transfer thousand dollars of the expenses demanded for designing and prototyping your idea a product.
For example, you should be prepared at least or execute yourselves or podzakljuchit end of following problems:
- Research of idea of a product (there any existing products or the patents already existing for this idea),
- Preparation for the document of the specification of a product (that it will make as it will look how it will be put in action and as the user will connect to it),
- Selling research (than it name who would buy it, how many will be, they pay as we will force clients to buy a product),
- Schematic or electronic krugooborot projects process
- Creation of the sheet of materials or the SNAKE and the list of the approved seller or AVL for each component in the project, is preferable with repeated sources identified, with the SNAKE and AVL for each level of meeting in a product
- Process of the project of an arrangement of board of the printed circuit (the unique has adjoined board, has twice adjoined board, or multilayered board; the size pcb; a board material)
- The mechanical packing project with the user interfaces (displays, buttons, switches, keys, connecting wires, power supplies, etc.); definition, whether demands product meeting that closing, internal konformnoe a covering, or potting have protected against humidity
- Development of program maintenance / the programmed equipment and software tools are required
- Acquisition of a component of a pre-production model, meeting of a pre-production model and the connected expenses of installation, and checking with program equipment / the programmed
- There can be also some UL and-or the regulating testing of consent FCC demanded depending on your statement a product (such as the Part 15 FCC and standards UL which can concern a product category),
- Revisions to the projects as required based on initial testing, come to an end prototyping to be demanded with probably additional rounds
- Any necessary changes from meeting of a pre-production model and checking processes should be included before the first manufacture which operate. It can demand, that change to schematic and printing projects of board, changes to mechanical packing, have changed on program maintenance / the programmed equipment, or cosmetic changes to investment packing. |
