Drying solutions
Increase storage life and reduce failure rates with drying cabinets from MP Dry
Electronic components and printed circuit boards are often hygroscopic, which means that they absorb moisture from the air. During SMT production, especially during the soldering process, these components can be damaged by rapid heating if they contain moisture.
Many components are classified according to the IPC/JEDEC standard J-STD-033, which specifies how components must be treated with regard to moisture absorption. Drying cabinets ensure that the components remain within a defined humidity range and thus meet the requirements of these standards.
Therefore re-drying
Prevention of moisture damage
ICs, LEDs and BGAs are particularly susceptible to moisture damage. Microcracks, the popcorn effect or delamination can occur if too much moisture has been absorbed. Therefore, depending on the MSL level, these components should be stored in drying cabinets.
Increase in process reliability
Components that have absorbed moisture are more likely to fail. Drying cabinets protect against moisture and thus help to ensure a stable SMD process and increase the reliability of the end products.
Longer shelf life
Drying cabinets make it possible to store sensitive components over a longer period of time without them becoming unusable due to moisture. This is particularly important for expensive components or components that are difficult to obtain.
Reduction of failure rates
Moisture damage is often not visible:
Many MSL failures pass the electrical test and are delivered to the customer. It is only later that failures occur.
Gentle process
Drying cabinets provide a gentle drying solution because the re-drying process is continuous.
Intelligent material tracing
The MP Dry Cabinets can be equipped with the Pick-by-Light technology from Inovaxe.
The chaotic storage principle allows full utilization of all available storage locations.
The smart systems recognize where which material has been stored and guide the operator during retrieval with light signals (Pick by Light).
Technology and equipment
Depending on the model, MP Dry combines drying, heating and a nitrogen unit: this way, an optimal result can be achieved for every requirement (re-drying time, material thickness, moisture level).
High-powered dehumidifiers remove moisture, with digital controls recording temperature and humidity. Nitrogen cabinets are a more expensive option, where over-pressure removes oxygen and moisture.
Automation in drying cabinets simplifies the management of MSD components using technologies such as barcoding and RFID, eliminating manual tasks and potential errors.
