Electronic Design services that we offer

circuit board

Custom electronics design & product development/prototyping service

This covers the design, prototyping and development of all kinds of electronic hardware. We design according to the requirements of the customer. Normally we require the specifications for a design job from the customer. In case the customer is not from the electronics field, then we can convert the requirements of the customer supplied in “plain English” to functional and electrical specifications and then proceed towards completing the design.

Embedded systems design (hardware and firmware/software)

An embedded system is the one that “embeds” a microprocessor (commonly called as “processor”) or a microcontroller (MCU) into the electronics design. Usually most everyday products that we use like refrigerators, automobiles, washing machines, microwave ovens and even your TV uses embedded microcontrollers in them. The best thing about embedded systems is that most of its functions are software controlled and can be changed easily without much work lost in re-designing the hardware. Although embedded systems design are a common part of any electronic systems & used in most of our designs, its worth mentioning it as a separate service since some customers might be specifically looking for this service.

PCB Design (Printed Circuit Board Design)

The printed circuit board, commonly referred to as the “PCB”, also called Printed Wiring Boards (PWB), is an inherent part of every electronic hardware. This is a board (usually green colored) which supports and interconnects all the parts together. Every custom electronics hardware that we design includes PCB layout designing, prototyping & assembly by default. We can also offer PCB layout designing (PCB designing for short) & prototyping as a standalone service in order to convert any existing schematic diagrams that you might have already designed into fully assembled prototypes. We work on 2 layer & multilayer PCB designs.

Electronic Product Design - from concept to completion

This involves the development of a full fledged, complete “ready to market” product and consists of enclosure design (either based on readily available enclosures, or custom designed mold preparation), hardware design (schematic & PCB design), user interface design (front panel/control panels), firmware/software design, product approvals (CE mark, FCC, UL etc). We are good at converting mere English descriptions into complete products by interacting with clients till their we understand what they have in mind.

Electronic Manufacturing Service (EMS)

TronicsZone is not only a reliable partner for design and prototyping, but also for small and large scale manufacturing of the designed products. We provide a single point contact from design to manufacturing.

Having designed the product we know the stuff inside out and are in the best position to take up manufacturing. We manage component sourcing, part inspection, board assembly, quality checks, functional testing, electrical testing through manual or automated test jigs which can be specially developed to suit the particular job under production.

We can handle small scale assembly in-house, but we have tie-ups with several local board assembly facilities to get the boards populated rapidly for large volumes.

Re-engineering services

This is most often used to

  • Reduce manufacturing costs.
  • Modernize old designs & reduce risk of it getting obsolete.
  • Correct flaws of existing designs.

Custom software development

We have a great deal of expertise and understanding of software development for the PC platform. Many times, it is required that the custom designed electronics should be able to connect to a PC for controlling or data uploading/downloading purposes (eg. a data acquisition system). We fully support and supplement our hardware designs with PC side software development. We have experience in developing applications in Windows and Linux platforms using common programming languages (Visual Basic, C#, SQL, ASP. NET, PHP etc)

Our Design Process

1. Specifying your design requirements:

The client must provide us with details regarding the design requirements (technically known as “design specifications” or “specs”). The specifications must include as much details regarding the design requirements as possible. Some clients may require a confidential non-disclosure agreement to be signed to enable them to disclose the details of the design. We welcome such agreements, given that, they are fair and acceptable. It would be ideal if the client can provide as much details about the design needed as possible. We understand not all clients have a sound knowledge about the technical details involving the design. In such cases, we can convert their requirements in plain English into technical specifications. We sometimes, also suggest improvements/amendments to the design by which it can be made even better or by which the manufacturing/design costs can be further optimized.

2. Providing a price quote for the design:

After studying the design specifications we will analyze the amount of work involved, number of engineers to engage on the design, resources needed, estimated completion time etc. Then we will get back to you with a price quote for the design. After the client accepts the price quote and places the order for the design, we will begin the actual design process.

3. Design process flow:

4. Standard deliverables:

By default, we include the following as standard deliverables with every design job.

  1. Schematic diagram with part values.
  2. PCB layout files in Gerber format. Drill information files in Excellon format.
  3. Source code in C or assembly language (well commented) and binary (hex) files for the microcontroller (if used).
  4. Source code and executables of PC software developed as part of design (if any).
  5. Complete documentation of the project.
  6. Fully working prototype (assembled on the PCB), ready for demonstration

These deliverables will be more than sufficient for you to begin mass production of the design by a third party manufacturer or through us.

5. Final changes/modifications to the design (optional):

After the prototype is examined by the client, on rare occasions, they may find it necessary to make a few changes or additions to the device before entering production. If the changes are small and does not involve any hardware changes & if they can be achieved through a simple firmware upgrade, then it will be done without any extra costs. For more elaborate changes that requires the hardware/PCB etc to be re-designed or if it takes a long time to implement the changes to the firmware, it will be charged appropriately. Normally, most of the deigns that we do satisfy the specifications or exceed it, so most of the times, this step will not be necessary.

6. Certifications – Compliance with CE/FCC/UL and other standards (optional):

The client must understand that in order to market an electronic device within a country, it will need to satisfy some regulatory requirements within that country. For example, the FCC part 15/part 68 requirements in USA or CE mark in European countries etc. It may be problematic or even illegal to market these products in some countries if they are not certified by the regulatory body. Understandably, meeting these regulatory requirements involves extra efforts & sometimes requires a few design iterations, and hence, can cost significantly more. Some regulatory requirements are easy to achieve and some requires more efforts. The customer is expected to specify the regulatory requirements that the designed product has to meet (if any) in their design requirements/specifications. It would generally cost more to design a product meeting regulatory requirements rather than just to design it for proof of concept (or demonstration purposes), since it involves elaborate testing and verifications from third party test labs to ensure that the design indeed meets the regulatory requirements. Most regulatory requirements are not required if the product is not intended to be sold or marketed (like for use within an organization/industry etc). These are just a few guidelines and for obtaining exact information or more details, the clients must contact the regulating bodies within their countries.

7. Small quantity test production (optional):

We can also support our customers with small quantity test productions (50 to 100 nos. at a time) which will enable them to test out their products in the market. We can help in the mass production by managing the entire production process with manufacturing companies with whom we have good understanding/tie-ups.

8. Large volume electronic manufacturing service:

We also supplement our design services by offering the complete end-to-end management of large volume manufacturing of the designed product where we manage the component procurement, inspections, assembly, testing & packaging with strict quality control procedures. This enables our customers to have a one-stop solution starting from product concept to mass production.
