HMLV Prototype PCB Boards

Like mold manufacturing , PCB also requires multiple prototypes verification before being put into production. But the PCB prototyping market is complex, some companies sacrifice quality to provide very low prices, and some cannot go multiple similar models.

We can solve the problem for you. With nearly 15 years of manufacturing experience, we have established complete processing lines to provide enterprise customers with high-mix prototype PCB boards and small batches to meet their needs.

In our factory, we adopt 2 shift production, to provide 24-hour fast delivery, and shorten the product launch time. Meanwhile, we follow the same high standards in all volumes, each PCB is UL certified and traceable to ensure that you receive satisfactory products, which is why 2000+ companies have cooperated with us for a long time.
