We are reflowing boards that have glop top components mounted on them. Do glop tops have the same moisture sensitivity as fine pitch? Should we be baking the boards prior to reflow?

Seika Machinery is pleased to announce that IC packages and LEDs can be stored in a dry box at five percent RH or less for indefinite floor life. Five of the McDry storage cabinets offer less than one percent RH, including: DXU-1001, MCU-201, MCU-301, MCU-401 and the DXU-580SF Feeder Storage Cabinet.

Occurrence of popcorn in IC packages while assembling them onto the PCB is a well known moisture sensitive reliability issues, especially for surface mount packages. Commonly reflow soldering simulation process is conducted to assess the impact of assembling IC package onto PCB. A strain gauge-based instrumentation is developed to investigate the popcorn effect in surface mount packages during reflow soldering process. The instrument is capable of providing real-time quantitative information of the occurrence popcorn phenomenon in IC packages. It is found that the popcorn occur temperatures between 218 to 241°C depending on moisture soak condition, but not at the peak temperature of the reflow process. The presence of popcorn and delamination are further confirmed by scanning acoustic tomography as a failure analysis.
