Dear client, Good day! It's Shally from MakerPCB again.
We are good in complex PCBs, such as multi-layer HDI boards, blind and buried via PCBs, multi-layer FPC boards, FR4 and FPC combined PCB, Min via hole is 0.1mm, and extra-long boards(120CM).
When the first PCBA is completed, we will also take photos for customers to check and confirm, and continue assembly after customer approval. Therefore, we can avoid many hand-made problems before shipping.
