With our sales and customer support team, we will quote and respond to your technical questions promptly. We will perform the PCB Design Rule Check before the production with no extra cost. We will work with you to resolve the non-conforming findings for your PCB board design. This process will ensure that your boards are standards compliant. Each board will be E-tested. Inspection report is available upon request.

On time delivery is our standard. We keep you updated about the order status and inform you of the tracking number after your order is shipped.

Our job does not end with delivery. We follow up with our customers and provide exceptional after sales support. If you have any questions, please email us info@sentakpcb.com
