Moisture Sensitivity Level (MSL) misconceptions can increase cost or delivery time due to unnecessary packaging restrictions
Some plastic packages used in the manufacture of quartz crystals and oscillators can absorb moisture from the atmosphere while in storage. When these parts are subjected to the high temperatures seen during reflow soldering, the moisture in the package expands into steam and can cause micro-fractures within the package or worse. These can result in destruction of the wire bonds within the package and thus product failure. The wire bonds form the electrical connection between the IC die and the metal lead-frame and as such are often encased in plastic during the moulding process. How likely this phenomenon is to occur is down to a number of factors such as the type of plastic used and the finish on this plastic, as well as the humidity, temperature and time of storage. This issue became of increasing importance after the introduction of lead-free solder and the consequential rise in the maximum peak temperature seen during reflow soldering. To manage this issue, it is necessary to quantify how susceptible specific crystal and oscillator designs are to moisture ingress and following… Read Full Blog Post
