Delivery & Shipping
FastlinePCB provides shipment solutions designed to support both development projects and long-term production programs. We understand that some customers require fast delivery for prototypes, while others need stable transportation arrangements for continuous supply.

FedEx express is the main shipping method used by FastlinePCB for international PCB and PCBA deliveries because it provides reliable service and convenient tracking. Customers who have their own transportation arrangements can also provide their preferred courier information or freight contacts.
For high-quantity shipments, sea freight can be arranged as a practical option to reduce transportation costs. Our team will communicate delivery details before shipment and prepare products according to transportation requirements.
We pay attention to packaging protection during the shipment preparation process. Different PCB products, including flexible circuits, rigid boards, and assembled boards, are packaged appropriately to reduce risks during transportation.

After-Sales Service
FastlinePCB provides a 12-month quality warranty for all products manufactured by our company. This warranty is intended to protect customers against quality problems caused by manufacturing defects.
If a customer identifies a potential product issue, FastlinePCB will review the information provided and perform an internal analysis. Our engineering team will check relevant production details to determine whether the problem is associated with manufacturing.
For confirmed manufacturing-related defects, FastlinePCB will provide appropriate support based on the actual situation. The final solution may include product replacement, repair, or other technical assistance.
Our goal is to handle quality concerns efficiently while helping customers maintain stable production and product reliability.
