In cooperation with our RoodMicrotec, we offer a competent solution for avoiding bottlenecks and ensuring the availability of components – a combination of controlled and secure storage including high-quality inspection services for your components.
While Totech takes care of the storage of your components, our partner is responsible for all accompanying quality services. This includes physical and electrical tests as well as material analyses of your components.
We test ICs with the most common package types, such as SOIC, QFP, QFN or BGA. Please contact us to find out whether your component type is also suitable for long-term storage.

Delivered parts are first checked for previous damage or mechanical defects in order to avoid unnecessary storage of defective components. The inspection procedure follows a standardised and proven process and comprises the following steps:
A corresponding incoming goods inspection report will be prepared for you based on the available results. The results of the incoming goods inspection determine the storage procedures. The presence or absence of a diffusion barrier layer in the structure of the connections for example, defines the interval of follow-up inspections during the storage period.
In addition, it might be necessary to perform a component-specific electrical input test if, for example, the origin of the components is unknown or the previous storage of the components has not taken place under controlled conditions. It is also better to sort out counterfeit components at an early stage before storing them for several years.
Possible in-house tests would be:
During the intermediate inspection, the components are again examined for solderability and intermetallic phase growth of the connection metallization. Depending on the result, however, this may also have acute effects on the further processability or storability of the components:
During the outgoing goods inspection, the components are subjected to the following tests:
If desired, a final examination of your components would also be possible at this point.
