7 No-Brainer Reasons to Prototype Your PCB Assembly

Prototyping is just as important to the electronics manufacturing process as designing, engineering, and testing. Ignore it at your own risk.

Original equipment manufacturers (OEMs) prototype by necessity because it tells you whether your design is truly ready to move forward into production. 

While you may find yourself wondering if prototyping is something you really have to do, in most cases you definitely want to prototype, and here’s why:

Prototyping PCB Assembly Work: 7 Ways It Bridges Design & Testing

There are a few situations where electronics contract manufacturers (ECMs) don’t prototype PCB assembly jobs -- such as really low-volume orders or simple designs. In all other cases, we encourage prototyping.

1. Avoiding Risk

When you don’t prototype, you run various risks, including:

  • Buying all your parts and finding that they don’t fit together properly
  • Producing a dangerous design that could harm the end user
  • Creating a product that won’t make it to market because it doesn’t meet your specs
  • Ordering a bunch of parts for your product that you can’t use

All of these situations will stretch out your lead time and production costs.

2. You Need Proof of Concept

No matter how confident you are in your concept, you can never be certain it’ll do what you expect until you prove it in real life. With many new and innovative designs, it’s impossible to know what the outcome is going to be until you put all the pieces together.

3. Is This What You Really Wanted?

You may have a design that needs to stick very closely to your specifications. Using a PCB prototype assembly service should show you that the contract engineering team did exactly what you asked.

If it fails from there, it’s your design to blame.

4. Prototyping is Critical to Cutting Red Tape

With many products, you are facing a variety of regulatory hurdles. Prototyping is the first step to getting past all those obstacles and moving on to testing.

Keep in mind that prototyping is only a single step to get to actual testing. It doesn’t guarantee that the product will work on the market. There are other tests to determine that. But prototyping is still an important step toward clearing your product with the FCC, UL, or whatever agency you’re dealing with.

5. 5 Duds are Better Than 200

There are so many things that can go wrong with a design, even one that looked lovely in CAD software.

For example, the battery life for the product might not be what you’d hoped for. At the prototyping stage, you have time to go back and fix the issue. Prototyping ensures you only make a few duds, instead of 100s or 1,000s.

6. Avoid Design-for-Manufacturing Issues

No matter how amazing the concept, it still needs to be manufacturable. Prototyping gives the production department assurance that there are no issues that will make manufacturing impossible, or so expensive that it is unfeasible. Common issues include:

  • Parts sizing -- parts are the wrong size for the layout and do not fit on the pad
  • Parts that can’t be washed
  • Parts that can’t handle soldering temperature

7. Software Needs a Prototype

Typically, software for your electronics can be started using evaluation boards. PCB prototypes are necessary to complete the software and test all the unique electronic hardware designed on your board.

How Much Does Prototyping Cost?

It’s impossible to give a specific price for prototyping because the amount of work involved varies greatly by the complexity of your project. The more complex it is, the more costly prototyping becomes. 

Regardless of the cost of prototyping, it’s a drop in the bucket compared to locking up the market share with your awesome new product.

Practice Makes Perfect

To recap, the greatest benefits of prototyping a PCB assembly are:

  • You’ll get a jump on the regulatory approval process.
  • You’ll have fewer setbacks if your design runs into problems.
  • You’ll save on costs on lead time.
  • Your company’s reputation won’t be ruined by your product hitting the market and failing spectacularly.
