prototyping your new electronic product idea
Have a gadget, music or video system, save time or the biggest problem-
A solution that was invented?
Even if you have expertise in electronic product design, you must complete some tasks and solve some problems, sales and sales before you have actual product design that you can produce.
Once you have completed the product specification documentation and marketing research, you should be ready to start the product electronics and packaging design process in order to assemble and test the prototype unit.
The first choice that must be made in electronic design is which microprocessor or microprocessor architecture will be used if your product concept needs processing power.
Most microprocessor or microprocessor devices have a variety of internal memory sizes, including non-
Volatile flash memory for program storage, number and type of input and output pins, package type for surface mounting or pass through
Hole applications, clock speeds and interfaces supported by the processor without having to add additional devices.
Once the microprocessor or microprocessor family has been selected, additional decisions must be made about which system clock frequency to use, how many processors and system memory the application needs, and how to support the software development process.
The choice of processor architecture must take into account the available software development and testing tools and software design resources required for product software/firmware design.
During the manufacturing process, additional decisions must be made on how to load the software/firmware into the memory of the processor.
Whether the design allows the finished product to accept a software/firmware upgrade initiated by the site or user, or if the product is a-
Time programmable unit?
Before the processor part of the design is completed, you must also define which types of external system interfaces are required (
Wireless connection such as serial port, parallel port, USB, Ethernet, 802, etc.
11x or Bluetooth, infrared, etc. )
And the minimum interface bandwidth rate required.
All of these factors will play a role in choosing the best processor product to use in the design application.
Some of the microprocessor/microprocessor product examples you can look at are the microchip PAL series and the Atmel product range, as both vendors offer some very powerful but low-cost processor solutions
Electronic components, including microprocessor and microprocessor, are usually installed and passed on the surface-hole versions.
There may be only one format for some electronic components (
For example, some transformers, relays, capacitors, power resistors, or connectors are only available in pass-throughhole packages).
Surface mounting components are preferred for any mass production, as they are generally cheaper to buy, easier to obtain, and allow for a more compact printed circuit board design, because the space occupied by the components is much smaller, it can be applied to both sides of the board if needed.
The use of surface mounting technology can enable the printed circuit board design to use smaller sizes and/or fewer layers, reducing the cost of the original circuit board.
However, surface mounting components can be-
If you do not have the right equipment and expertise, it is difficult for the House to assemble and Weld, if not impossible.
The completed design will include a power supply section that will provide the voltage and current levels required to design the assembly.
As part of the power supply design, the input power supply option can include plugging the device into a 120 VAC socket and converting the AC voltage internally to the appropriate regulated DC voltage level.
You can also choose to use an external power adapter that converts 120 VAC to a DC voltage level and then adjusts the input DC voltage level to the level required for the design.
The third option is to have the product powered by a battery.
If your product is battery powered, in addition to defining the battery technology and the number of amps stored in the battery, you should also consider whether a rechargeable battery design or an end-user replaceable battery design is best suited for product application and pricing.
Once the electronic design and printed circuit board design are completed, the mechanical packaging and external housing design can be finalized and the initial software development can be completed.
Now is the time to assemble and test the prototype unit, a decision must be made on the manufacture of the initial prototype unit.
Options include ordering all components and assembling prototype products in-
If you have assembly expertise, subcontract the prototyping process to a domestic contract electronics manufacturing company or subcontract the prototyping process to an offshore contract electronics manufacturing company.
If you do not have the expertise or equipment to properly assemble the prototype unit, you should prepare a list of companies that can support your prototype and production needs and start identifying your best options.
In addition to determining who will assemble the prototype unit, you should also determine which option you will use to manufacture the production unit.
Options include self-manufacturing units, assembly with domestic and foreign package units, or outsourcing unit assembly with offshore electronic manufacturing service providers.
If an external manufacturing source is planned to be used, consider some companies that specialize in the production of small batches of professional components, such as prototype units or initial production, but cannot support mass production cost-effectively due to capacity constraints.
Other companies, on the contrary, focus only on high volume.
From your point of view, the number of units produced in large quantities may not be large enough to attract any interest from a strictly high-volume manufacturer.
You should also consider the delivery time after receiving your purchase order as a factor in selecting an external assembly source.
In the process of evaluating e-Manufacturing service providers, another important factor to consider is the design assistance they may provide throughout the product development process.
Services such as electronic design and printed circuit board layout design, component selection and procurement process
Purchasing components, shell design, mechanical packaging design, and the ability to provide production from prototyping to small batches to large batches are all of great help to you.
In addition, contract electronics manufacturers can also provide advice on improving manufacturing capabilities, reducing component costs, and improving product reliability.
Be sure to have the right
Enter into a disclosure agreement with any and all parties involved in this process to protect your intellectual property rights.
You must also define how to test and package the products manufactured.
Once the product is prototyped and tested successfully, it is important to determine the number of manufacturing units at the initial production run and mass manufacturing levels.
You must also understand the distribution level of the product (
Cut profits at every level)
Before it reaches the consumer to buy.
I don\'t want to stop you if you\'re an inventor, or have good electronics ideas, but before you commit to the thousands of dollars you need to design and prototype your product ideas, you must consider all of these activities and their associated costs.
For example, you should at least be prepared to either perform your duties or subcontract to complete the following tasks :-
Research on product creativity (
Does this idea already exist with any existing product or patent)-
Preparation of product specification documents (
What it will do, what it will look like, how it will power, and how the user will interact with it)-
Market research (
What is its name, who will buy this, how much will they pay, how can we get customers to buy the product)-
Circuit design process-
Create bill of materials or BOM and approved supplier list or AVL for each component in the design, it is best to identify multiple sources and provide BOM and AVL-for each assembly level in the product-
Design process of printed circuit board layout (
Single panel, double panel or multiple panel;
Size of Pcb; board material)-
Mechanical packaging design with user interface (
Display, buttons, switches, keys, interconnect, power supply, etc. );
Determine if the product assembly needs to be sealed, with an internal shape-preserving coating or filled to prevent moisture-
Required software/firmware development process and software tools-
Prototype component procurement, prototype assembly and related installation costs, as well as testing with software/firmware
Depending on your product application, some UL and/or FCC compliance tests may also be required (
Such as FCC parts 15 and UL standards that may apply to product categories)-
According to the initial test results, necessary modifications to the design as needed, additional prototyping may be required --
Before the first production run, any necessary changes in the prototype assembly and testing process must be integrated.
This may require changes to the schematic and printed circuit board design, changes to the mechanical packaging, changes to the software/firmware, or appearance changes to the enclosure packaging.
