Manufacture of Bare Board PCB

 

Our manufacturing factory is well equipped to manufacture high quality printed circuit boards. We are very flexible to meet the different requirements in manufacturing.

We do quick turn production, as fast as two business days for prototypes and small volume orders. We also do mass production with blanket orders with monthly releases. The lead times can vary between two days to one month, depending on your needs. The best prices are usually with a standard lead time of 10 business days.

Our on-time shipping rate is above 99% with 70% of the orders shipping earlier. No cutoff time for quick turn orders, we can start quick turn order 24 hours a day. The cut off time for standard lead time is 8 pm for standard lead time orders, otherwise, the order will not be considered placed until the following day.
