Testing Procedures

We perform multiple quality assurance procedures before shipping out any board. These include:

Visual inspection,

X-ray Inspection,

AOI (Automated Optical Inspector),

ICT (in-circuit test), and

Functional test (test modules need to be supplied) .


Quick turn lead times

If all the parts are available, normally the PCBA prototype job can be finished within 3 to 5 days in our factory. This means that the order can be delivered within one weeks once assembly job start.
