Shipping&Packing
We guarantee that we will ship at least 100% of your finished pcba within the promised lead time,unless there is holiday or power failure.The assembly
order does not start until the last component is received, so occasionally there are delays in receiving material that are beyond our control
and therefore not considered as a late shipment.
The finished pcba is made of anti-static packaging material to ensure that the components are not damaged.
