What We Do
Our team can help you with market research and analysis, gathering and evaluating critical data on market trends, consumer behaviour, and the competitive landscape. With these insights, you can make informed, strategic decisions to optimise your PCB and electronic product development, ensuring a competitive edge in the industry.
We are among the few PCB manufacturing companies in Singapore that can assist you in planning and developing your products, services, technology and processes. In addition to producing new products, Promax Technology Integration R&D can also be used to improve an existing product or service with added functionality leading to the discovery of a brand new product, product line or service.
Rapid PCB prototyping allows for quick and iterative design, fabrication, and testing of printed circuit boards, accelerating product development cycles.
Our rapid PCB prototyping services enable quick and iterative design, fabrication, and testing of printed circuit boards, helping accelerate product development cycles.
Our custom PCB assembly is followed by our high-quality production and delivery of parts. We populate your PCB with components that are either sourced through you or our partners. Once the PCB assembly phase is done, we carry out thorough tests to ensure that your PCB is consistent with the designs. This involves quick and inexpensive tests. Being an expert PCB board maker, we deliver a complete turnkey PCB prototype that saves you time, money and difficulty with a one-stop solution.

What Our Clients Say

I have been working with Promax for a few months on several projects. They are very professional and I am always impressed with their work. Mr Yeo and his team are helpful and show professionalism. They are able to respond and fabricate the PCB quickly even in the event of COVID-19. If you happen to be looking to develop your product, you should talk with Promax!

We have been working with Promax for more than a year. They are very professional, work fast and efficient. I will definitely recommend them to anyone who wish to have their PCB made. We have also worked with other PCB manufacturers in the past (local ones), but none of them could match the quality and service like Promax.

I have been working with Mr Yeo and his team for a while now, they are very professional and fast in response. There was an urgent request that I had to be done on time, and Mr Yeo and his team have been helping me to finish the PCB as soon as possible. I would recommend Promax for you if you need any help for your idea or product.
