I have a board that was designed in 6 layers, using a blind via and very small trace paths, and as result has increased the production cost greatly. What I need is for someone to take the current design schematic, and either separate the design into two independent boards that interface with each other and mount within the same enclosure space, or fix the board so that it is not so close to produce, meaning increase the trace or component issues. 
4 days
1. Separate the existing PCB, (BRD file will be provided for job), into two boards one with 4 layers and another with 2 for example, that result in the same collective PCB functionality.
2. Modify and correct the existing issues with the board that are suspected causes of the increased production cost, i.e. the blind via, and small trace areas.
3. Alternative solution that meets the existing functionality of the board, but lowers the cost.
4. Delivery of all schematics, BOM, Gerber’s, source files, and PDF’s.

$40/hr - Arduino Expert


Programming with Ardunio for simple square wave pulse generator.
Four inputs, four outputs. The four outputs are the generated square waves, and each one is activated by one digital input

The square waves should have a ramp time, for acceleration and decceleration.

Modify an Existing Solidworks design. Design is of a compartmentalized box that needs dimensional changes.



How to Develop a Product


So you’ve come up with a great product idea, did your research, have basic sketches, and even built a functional prototype with a shoelace, toothpick, and some duct tape; but now what? It’s time to pursue professional development. The following information will give a high-level view of the various stages in product development.

The first phase is the Design Phase; the objective of this phase is to illustrate how your McGyver’d prototype can look more like a sleek, sophisticated product. The importance of a good product design is becoming increasingly important- a product is only as good as it’s user experience. Product design should take into account the use-case of the product, target market, demographics, and overall ergonomics. At the end of the Design phase you will have concept sketches that will help the Engineer develop the product.


The Engineering Phase is up next. It is here that a product will spend a significant amount of it’s development. The Engineering phase ensures that the design if suitable for manufacturing (See: Design for Manufacturability). When you find an Engineering service, they will work directly with you to design a manufacturable product that resembles your concept sketches. The output of the Engineering phase is a 3D file that can be used in prototyping.


The Prototyping Phase typically goes hand-in-hand with the Engineering phase. With the rise of 3D printing, product feedback is much cheaper and faster. You should expect the Engineer(s) to utilize 3D printing services to produce physical representations of the product. The Prototyping phase is an iterative and frequent process and will help expose any design flaws. After going through several design improvements, you’re now ready to bring in the big guns -  Low Volume Production.


Low Volume Production is used to manufacture a few thousand pieces for relatively low costs. The overall process and objective is to create a mold/cast of your completed prototype so that you can repeatedly produce your product in a scalable manner. Methods of Low Volume Production may vary depending on the materials and quantities desired; Cast Urethane Molding is great for low-cost, lower-volume production; Injection Molding is typically used for larger volumes of production; and Casting is a molding process where the object is broken out of a mold and is great for complex shapes.


With a few thousand pieces now at your disposal, it’s time to start selling and distributing your product! However, Distribution and Order Fulfillment are subjects for a future writeup :)

To recap, a product’s development typically experiences the following phases:

Idea and Validation

Industrial Design

Engineering Design


Low Volume Production

What is ProtoExchange


Finding a manufacturer is tough - you have to scour the internet for manufacturers who have the necessary capabilities, industry expertise, and locale that is relevant to your project. Additionally, you have to take a leap-of-faith and trust that the manufacturer is reputable and produces high-quality parts. All of this uncertainty results in a stressful experience - not an ideal situation when you’re building a product!

At ProtoExchange, we help eliminate such headaches and risks. We vet manufacturers before you take a leap-of-faith, we pull in public and private data to help make your search seamless, and we work directly with you to ensure that your project’s needs are met.

Our mission is to not only make manufacturing easy, but provide a layer of transparency into the manufacturing processes to alleviate stressful situations. Welcome to Manufacturing 2.0.
