The encapsulation process can be largely divided into a hermetic method in which a ceramic plate or a metal lid is attached to seal, and a molding method in which a plastic epoxy material is melted and cured to seal. Of these two, the hermetic method is rarely used currently while the molding method using epoxy molding compound (EMC
Encapsulation and Molding Compounds: Plastics are used as encapsulation and molding compounds to protect semiconductor chips and ICs. These compounds provide mechanical protection, environmental isolation, and electrical insulation.

Plastic Encapsulation is a process where the semiconductor chip is assembled in a package which is directly over-moulded with an epoxy mould compound rather than being in an air cavity. This process has been well known in the semiconductor industry for many years but has over time migrated to large assembly houses, predominantly in Asia.

Molded chip polymer tantalum capacitor encases the element in plastic resins, such as epoxy materials. The molding compound has been selected to meet the requirements of UL 94 V-0 and outgassing requirements of ASTM E-595. After assembly, the capacitors are tested and inspected to assure long life and reliability.
The conductive polymer layer is then coated with graphite, followed by a layer of metallic silver, which provides a conductive surface between the capacitor element and the outer termination (lead frame or other). Molded chip polymer tantalum capacitor encases the element in plastic resins, such as epoxy materials.
Plastic Encapsulation is a process where the semiconductor chip is assembled in a package which is directly over-moulded with an epoxy mould compound rather than being in an air cavity. This process has been well known in the semiconductor industry for many years but has over time migrated to large assembly houses, predominantly in Asia.
Unused capacitors should be re-sealed in the MBB with fresh desiccant. A moisture strip (humidity indicator card) is included in the bag to assure dryness. To remove excess moisture, capacitors can be dried at 40 °C (standard “dry box” conditions). For detailed recommendations please refer to J-STD-033.
In solid electrolyte capacitors, a dry material (manganese dioxide) forms the cathode plate. A tantalum lead is embedded in or welded to the pellet, which is in turn connected to a termination or lead wire. The drawings show the construction details of the surface mount types of tantalum capacitors shown in this catalog.
MSL for each particular family is defined in the datasheet - either in “Features” section or “Standard Ratings” table. Level 3 specifies a floor life (out of bag) of 168 hours and level 4 specifies a floor life of 72 hours at 30 °C maximum and 60 % relative humidity (RH). Unused capacitors should be re-sealed in the MBB with fresh desiccant.
