Outsourcing hardware design & PCB (printed circuit board) electronics refers to hiring a freelance firm or team of engineers, 3D designers<\/a>, and developers to manufacture a product\u2019s physical electronic system rather than creating it in-house. For different startups, outsourcing hardware design and PCB electronics is quite common and considered a best practice, especially for those that do not have any electrical engineers on the team. Outsourcing these processes to specialized experts can accelerate development while reducing overhead costs associated with hiring a full team. Also, experienced design firms and specialists can prevent costly trial and error. <\/p>

If you are in the business of consumer and industrial gadgets, smart home devices, wearables, medical electronics, digital automation systems, and more, outsourcing may just be what you need. There are numerous engineers and other specialized teams that offer outsourcing services to different startups. As an external service provider, Cad Crowd can connect you to a team of world-class quality engineering designers<\/a> and contractors that will fit your specific design and manufacturing needs. But before you make the move to outsource for the first time, here are some mistakes that new startups typically make and how you can avoid them. <\/p>

1. Choosing the suppler with the lowest quote <\/h3>

Big savings now may lead to bigger expenses later. There are many factors to consider when looking at the price. First is the experience, if the team can execute well according to your specifications. Second, cheap design does not necessarily mean good quality. You don\u2019t want to end up with a product where everything was done haphazardly and rushed. Third, a quote can be very cheap because not all costs are upfront. <\/p>

You may end up paying for a lot of hidden costs for any type of rework or troubleshooting.  Always keep in mind that redoing a product from scratch, as well as any delay, is more expensive than executing it correctly on the first run. Choosing the cheapest product design firm<\/a> can affect your product, launch schedule, and most especially your budget, so always weigh your options carefully and choose wisely. <\/p>

2. Having no detailed product specifications <\/strong><\/h3>

Suppliers are not magicians. You cannot just order a product without clear, specific requirements and expect it to deliver exactly what you want. For a startup, it\u2019s a rookie mistake to expect your supplier to know the ins and outs of your product, especially when it comes to technical electronic specifications like power consumption and requirements, outdoor or indoor usage, and even local regulations. <\/p>

The moment there are gaps in the details, suppliers often tend to make their own adjustments. This can lead to possible multiple revisions and redesigns along the line. Remember,  every redo and rework and every week of delay will potentially cost you thousands of dollars, so always note down and document every single specification detail of the product. <\/p>

3. Not designing for mass production <\/h3>

Design for Manufacturability (DFM) services<\/a> are more important than you think. Your PCB prototype can work perfectly, but it may not work for mass production. The layout should always be fit for manufacturability. All the tiny specifications such as tight spacing, dense layouts, and poor planning of panels may result to issues that go beyond the capacity and capability of factories. <\/p>

Also, if the proposed components are difficult to source, it becomes a major issue in the manufacturing process. Always keep in mind all manufacturing requirements when designing the layout and the system itself. If the PCB or hardware design is not scalable for mass production, this will cause delays in the product launch, increase per-unit costs, and reduce yield. <\/p>

4. Non-availability of all parts and components<\/h3>

Before going to production, startups need to ensure that the design prototype includes all parts and components that are readily available at any time. The supply chain is one of the key parts of the manufacturing process, and missing parts will stall the entire production for months on end. Make sure to verify that all parts are not obsolete, have a short lead time from order to delivery, and are sourced from a single, credible source. <\/p>

If parts are unavailable, the PCB design team<\/a> must create a completely new PCB layout. Then, there\u2019s the problem with reapplying for another round of certification, which will cause additional delays. Lastly, any additional parts would require a firmware rewrite to ensure compatibility with the entire system. Choose the right parts and make sure they are readily available anytime, at all times. <\/p>

5. Assuming that the first PCB prototype already works <\/h3>

Any type of hardware always requires and needs several iterations. The first revision of any prototype is never perfect. Failing to plan for multiple revisions will prove very costly down the line. Never assume that the first one works immediately without any problems. The real scenario is that Revision No. 1 is when the electronics design team<\/a> discovers major issues. Maybe there are faulty components, relay disconnections, gaps in the system, etc. Revision No. 2 is where any functional issues are fixed, such as parts not working together properly. Even that\u2019s not enough, because Revision No. 3 is when the system’s performance can be optimized with additional tweaks. <\/p>

These iterations are also when you can assess manufacturability and determine whether the product is ready for mass production. At the beginning of the design process, always include in the timeline and the overall budget considerations for multiple revisions and iterations. This ensures that your startup will either burn through funds or experience delays in the product launch, which can definitely result in your investors being frustrated or displeased. <\/p>

6. Lack of communication with outsourced suppliers<\/h3>

Before choosing the right team of external engineers and PCB designers<\/a> to work with, make sure that you are prepared to communicate with them regularly. Have an organized communication system in place to share important files and documentation, update and review each other weekly, create logs for every approval and revision, and more. Creating a product requires very precise, no-fail coordination between the firmware and the hardware. <\/p>

Clear communication must be maintained at all times to control the various revisions and iterations being applied. Also, having an open line between the startup team and the outsourced team will make it easier to quickly manage and resolve any issue that become escalated. It is critical to avoid any miscommunication to prevent major issues such as pin assignments out of place, incorrect voltage rails, or firmware that is completely incompatible with the hardware being designed. <\/p>

7. Not securing ownership of the product source files <\/h3>

It would be a massive problem if you do not gain ownership of the original design files. Here is a list of the important files you need to secure after working with any outsourced supplier: Full schematic design, PCB layout files, the Entire library of parts and components, and the Complete source code for all installed firmware. Why should you ensure that all these design files are in your possession? Because if you change suppliers or hire an entirely new design engineering team<\/a> in the future, they do not need to create revisions or reworks from nothing. <\/p>

Without the source file, revisions and redesigns would have to start from scratch, which can waste many months on rework on an existing product design. Even worse, if you try to request the original file from the previous supplier, you will likely have to pay very high fees to access it. Always ensure that ownership your own product\u2019s design is very clearly stated in the contract to save yourself. <\/p>

8. Putting off compliance certifications <\/strong><\/h3>

All electronic products must be certified to ensure they operate safely and do not harm users or the environment. One thing about startups is that they always focus first and foremost on the design and remember to comply with necessary EMI\/EMC and Certifications later on. One of the most important things that startups need before you can proceed to market a product is to comply with all necessary certifications that declare your product as up to global standards. <\/p>

But what if the product fails to meet EMI (electromagnetic interference)<\/a>, which ensures that the device does not produce unwanted emissions, or EMC (electromagnetic compatibility), which ensures that the product works properly? Then your product will have to undergo a major revision in the PCB layout and a total overhaul and redesign. Fixing these technical problems is a long, drawn-out process that costs a lot of money. So, even when planning the entire system from the beginning, always consider the compliance requirements.  <\/p>

9. Not planning for testing <\/strong><\/h3>

Designing a PCB with no plan for testing is a formula for disaster. Engineers should always design a PCB with a plan of how to test it, making sure that these are included in the initial prototype: multiple test points to check the signal, programming connectors where firmware can be uploaded, built-in access points to test chips, and plans on how to verify boards before they are shipped out. If you cannot test a board, it will be very difficult to identify faulty or defective boards, which part or component is defective, and why the defect occurred in the first place. This results in a lot of boards getting thrown away. Another problem is that it would be very difficult to troubleshoot and debug. <\/p>

If there are no access points on how to check, the design engineering team<\/a> would have to dismantle boards piece by piece, and waste so much time trying to guess what the issue is and where it is. Another worst-case scenario is that if boards are not tested before shipping, customers will discover the problems at home. This results in product returns, and in the end, the reputation of your startup and its products will feel the backlash.Always design your PCB\u2019s schematics and layout with a plan to test it first. <\/p>

10. Not consolidating the firmware and hardware<\/h3>

The hardware is the physical board, while the firmware involves the software that runs inside the chip. Both are not independent of the other and must be taken together. It\u2019s not uncommon for startups to outsource to different suppliers for hardware design and software development. This is not a problem if there is early communication and collaboration because anything related to hardware has a direct connection with how the firmware works. <\/p>

The problem with hardware and firmware not being in sync from the start is that when issues crop up, the PCB assembly team<\/a> needs to make a new board, rewrite all the firmware, build totally new prototypes, which, of course, costs thousands of dollars. Even before actual layout design begins, both hardware and firmware teams must consolidate and integrate their work processes to ensure smooth outcomes. <\/p>

11. Setting unrealistic time schedules and deadlines  <\/h3>

Startup founders need to remember that software and hardware do not follow the same timelines. Hardware design involves many physical processes, such as planning the architecture, designing schematics and PCB layouts, procuring materials, fabricating prototypes, testing the product, and fixing and revising it. This process flow for the hardware alone takes months. Unlike software, which involves coding and testing, a physical PCB cannot be updated in a couple of minutes. Fabrication depends on the lead time provided by the manufacturer or factory. <\/p>

This lead time also depends on the shipment schedule of the parts and components, which can be easily affected by climate and weather disturbances or by any problem in the supply chain, including political issues. Therefore, the timeline must always depend on the hardware schedule. Setting unrealistic timelines can result in the investors losing trust and confidence in your electronic product design company<\/a>. If schedules are not laid out clearly, the teams will burn out from stress. Always plan accordingly based on the hardware design process. <\/p>

12. Lacking a sustainable manufacturing plan<\/h3>

Most startups focus a lot of energy on a successful, working prototype, but sometimes forget how to scale their product. The ability to transition to the manufacturing and mass-production stage is often overlooked. Thus, startups should remember that the actual product must be easily scalable, even when produced in the thousands. Some important things to keep in mind are to first choose the right manufacturing partner. Make sure that your partner\u2019s factory is experienced in handling fine electronic components, assembling high-speed PCBs, and is able to maintain quality control despite the large-scale production. <\/p>

Working with the right contract manufacturer is an important factor for success. Prototypes are sometimes assembled by hand, but mass production is created through automated machines. If your design easily falls apart on the assembly line, it means your manufacturing plan has suddenly become too costly. Lastly, don\u2019t forget that particular parts and components might no longer exist in just a few years. Always plan for alternatives and secondary sources once the original ones become obsolete. <\/p>

What makes a healthy outsourcing relationship?<\/h3>

Before outsourcing hardware design & PCB electronics to an external pcb layout design team<\/a>, take note of these important guidelines to ensure positive outcomes.  <\/p>

Scope of work and list of deliverables<\/h3>

You should always clearly indicate what the supplier will design, along with a complete list of features and performance goals. Also, the limitations and what is not to be included must also be stipulated. The number of prototype revisions should be clearly stated, taking into account the number of iterations and revisions required for the design (see section 5). The deliverables (schematics, PCB layout files, firmware files, test plans, etc.) must be clearly listed, along with a timeline with reasonable lead times and deadlines. Lastly, the ownership of the IP and design source files must already be identified at the beginning.  <\/p>

Organized communication <\/h3>

A strong and healthy relationship with the outsourced supplier is defined by regular updates. Having an open line of communication where all parties collaborate in a shared space is also critical for the engineering design<\/a> team. There should be weekly coordination and review, as well as a platform to track and log all hardware and firmware decisions and approvals. <\/p>

Discussion of potential risks<\/h3>

Always bring up potential risks with your outsourced supplier, including the availability of the parts and components, any concerns about temperature, issues on EMI, compliance with regulations and requirements, and, of course, the cost versus the actual performance. Discuss these things openly and develop strategies to manage them immediately. <\/p>

Collaboration between hardware and firmware<\/h3>

If you outsource these two things separately, make sure coordination and collaboration start from Day 1. The software engineers responsible for the firmware should review the schematic design very closely. Technical details, such as pin assignments and even power modes, are reviewed early and approved together. Before the actual PCB layout, integration planning has already been done. <\/p>

Design for manufacturing<\/h3>

Make sure your outsourced supplier already has mass production and manufacturability in mind. The 3D engineering team<\/a> needs to consider how to scale and produce in bulk even during the layout design stage. They know how to choose parts and components that are always available with a steady and stable supply. Test points are a must during prototyping, and that prototype must be ready to scale up and be mass-produced anytime. <\/p>

Clear breakdown of costs<\/h3>

To ensure a transparent relationship with your outsourced supplier, make sure that you understand the cost of engineering, the cost of prototype, and the costs of future revisions. Always ask for a breakdown of every single expense throughout the entire process. <\/p>

Turnover and ownership of files <\/strong><\/h3>

Your outsourced supplier must be willing to provide you with the following design source files: native schematics, PCB layouts, component library, source codes of firmware, and manufacturing files. You should never be held hostage by your supplier.<\/p>
