                                Probe Testing A flying probe test is available to test both 
                                SMT and through-hole assembled printed circuit 
                                boards for manufacturing defects. Being a fixtureless 
                                test machine, and it is ideal for contacting leads 
                                of fine pitch SMT components.

                                conductibility. The testing reports can be sent 
                                with pcbs to the customers when we ship the pcb 
                                to the customers
