I have been working with Sky-win for a few months on several projects. They are very professional and I am always impressed with their work.. 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 Sky-win!

—— Vinay Bassi

We have been working with Sky-win 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 Sky-win.

—— Michael Saleem

I have been working with Ms. Tiffany and her 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 Ms. Tiffany and her team have been helping me to finish the PCB as soon as possible. I would recommend Sky-win for you if you need any help for your idea or product.

—— Shams Rehman

We purchase PCB’s from Sky-win for the last 5 years. Our boards are high complexity 6 to 20 layers with controlled impedance and Gigabit differential signals. Excellent quality, price, and customer service. Thank you Sky-win! Highly recommended.

—— Bharat

Sky-win has been a preferred vendor of mine for almost 10 years. From their quotes, to confirming purchase orders, to manufacturing our boards, Sky-win has excelled in every area. I am happy to have been partnered with them for such a long period of time. I give them a 5 star recommendation!

ODM PCB Assembly Service

High Quality PCB Assembly Services: A One-Stop Solution For Your Circuit Board


A full set of PCBA is our core business, even in the proofing stage. We use our professional and resources to do PCB proofing, material procurement, PCBA manufacturing one-stop PCB assembly services for you. If you want to solder specific devices, we will also provide such services.


Avoid the trouble of purchasing PCB components, make you focus on your PCBA design. Our purchasing team will purchase more components from the same supplier and use the best method to complete the purchasing task. We will optimize packaging (belt, tube, bulk, etc.) with quantity selection in smaller BOM to reduce cost. We have the ability to handle difficult-to-order materials and obsolete components. We purchase materials according to the material model and manufacturer in your BOM. Don't worry about the danger of any alternative materials. We will not change your design. Alternative materials will also be approved by you before use.


The price of the whole service includes welding cost, smooth plate cost, and material purchase cost. Quotations for electronic components are from Digi key, Mouser, Avnet, arrow, future, Newark, or designated suppliers. We don't charge any purchase fee.

We understand the importance of punctual delivery. In PCB fabrication, material procurement has been carried out at the same time. We will review engineering problems and component problems before welding. If there are no hard-to-order components and documentation errors, a full set of PCBA manufacturing usually takes two weeks.
