4.Reliability

For many of our products – especially implantable devices – failure during operation is not an option. In addition, PCBs with hidden defects will cause high costs in the subsequent process chain. Uniwell attaches great importance to QA to ensure that only PCBs that meet your quality requirements are delivered. PCBs will be inspected according to IPC 600 class 2 or pursuant to customer specifications. The quality management system is certified according to ISO 9001 and fully integrated in the ERP system.

Manufacturing documents and product specification
Change control is realized by issuing a unique identification number for every revision of a given PCB and all product specifications, drawings and fabrication documents are referenced to this number.
Additionally, PCBs with difficult requirements are labeled “Golden Board” and during production of the prototype all production parameters of each manufacturing step are meticulously recorded. This ensures that subsequent production lots will be manufactured exactly the same way (Golden Board). Changes are only implemented in collaboration with the customer.


Automatic optical inspection (AOI)

All layers are subject to a 100% automatic optical inspection. This test ensures that tracks will have the required dimensions (e.g. local nicks of tracks) and will match the required pattern. The metal pattern is compared to the original Gerber data and the pattern is not learned from an initial board.


E-testing

All PCBs undergo an electrical test at the end of the manufacturing process. In addition to the usual open and short tests, high impedance, leakage current, capacitive and inducativ load as well as high voltage testing can be offered.
Usually flying probe testers are used. Our e-test equipment possesses automatic optical registration and soft touch needles that leave no marks on the contact pads which is especially important for bond pads.
