PCB Assembly FAQ

Find answers to common questions about our PCB manufacturing and assembly services

What does TopFast do?

TopFast provides high quality, on-time delivery of PCBs, PCBAs and one-stop solutions, integrating design, manufacturing, assembly, and sourcing in one global specialized supplier.

Your prices are so low, how do you ensure excellent quality?

  1. We constantly introduce new equipment and technology.
  2. We use high quality materials to ensure the quality of boards.
  3. We have more than 25 experienced executives and technicians who have been engaged in PCB production for more than twenty years, with rich experience in production management and professional PCB skills. Because we have an efficient direct sales channel, our overhead is extremely low. Every penny you pay is for the highest quality!

What is your lead time?

The fastest lead time we can support is 12 hours. 1 hour prompt quote. 4 hours prompt engineering. This depends on your product requirements and quantity. In addition, lead time will be included in your quote.

What about shipping cost?

For small packages, we recommend using an express courier (e.g. DHL, UPS, FedEx and EMS door-to-door service!). This is the fastest but also the most expensive way. For large parcels, ocean freight is the best solution. We can only give you accurate shipping rates if we know the quantity, weight and shipping method details.

I only have a schematic, can you make a PCB for me?

Yes. We can lay out the PCB according to your schematic and then arrange the production. Please contact us at Please send your schematic and requirements to op@topfastpcb.com and we will provide a quotation accordingly.

How do I order?

Send an e-mail to: op@topfastpcb.com with an email containing the following information: name, company, address, phone number, email address, product number, quantity, product time and any other information you would like to share with us. Attach your gerber file.

Where do you manufacture your PCBs?

As a global PCB manufacturer, our factories are located in Guangzhou, China and Shenzhen, China, utilizing the advantages of each region to provide you with the best service.

Do you offer free samples?

We do not offer free PCBs, if you want to verify our quality before mass production, it is better to submit a prototype order. After verifying our quality, you can easily place an order for any quantity you need.

I am ready to place a large order, but I need to test your quality first. Is that OK?

Sure. You can place a prototype order first. Use any of the options to check the quality and then let us know if you want to proceed with mass production.
