Our primary business is contract manufacturing for PCBAs in southern China, and although we do have customers throughout the world, but do not currently stock materials or finished product anywhere but China. Lead times vary, and really have to do with the complexity of the product and the components used. As I'm sure you know, components are the driver for lead-times on finished product in the current post pandemic world.
If you do have customers that would need PCBA production services while taking advantage of the lower cost capability of China manufacturing, we would certainly be interested in the opportunity to quote the project. In addition, we can help with design services for new concepts, reverse engineering, product redesigns, etc. These engineering services are provided both locally in the USA and in China. We can also offer mechanical design as well, if there is a need for your customer.
