We are very satisfied with both the quality of the PCB boards and the delivery speed. The ordering process is straightforward, communication is good, and the boards consistently meet our expectations. One area that we find limiting is the panelization policy. In our case, multiple PCB images placed on a single panel are treated as separate products rather than a single board. We understand the manufacturing reasons behind this approach, but greater flexibility in this area would be appreciated and would make the service even more attractive for prototype and small-batch development projects. Overall, we are very happy with Aivon and would gladly recommend your services.
