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.
- We constantly introduce new equipment and technology.
- We use high quality materials to ensure the quality of boards.
- 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!
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.
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.
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.
