Boundary Scan, Functional Test, Test automation

Increased test coverage and reduced test times are the key qualification tools for enabling the best production yield. As detection of the manufacturing faults after the shipment impacts the customer satisfaction and increases overall cost of test and repair, it is important for the FAB and Assembly houses to employ right Manufacturing Test Strategies. The product companies also need to collaborate with their FAB and Assembly houses and provide the right test processes, scripts and test programs.

Our Test Engineering group understands this manufacturing test strategies much better as we work very closely with the fabrication-house and assembly-house to produce quality PCB and packages. Our Test engineering services are created to help you to achieve better test coverage and test times at a reduced cost. We provide integrated test engineering solutions involving Boundary Scan Test, Functional Test and Test process and equipments automation.
