Ndi kusintha kwa moyo wa modemu ndi teknoloji, anthu akafunsidwa za kufunikira kwawo kwa nthawi yaitali kwa magetsi, samazengereza kuyankha mawu otsatirawa: ang'onoang'ono, opepuka, othamanga, othamanga kwambiri.Pofuna kusintha zinthu zamakono zamakono kuti zigwirizane ndi izi, luso lamakono losindikizidwa la board board lakhala likudziwika kwambiri ndikugwiritsidwa ntchito, pakati pawo teknoloji ya PoP (Package on Package) yapeza mamiliyoni ambiri othandizira.

Phukusi pa Phukusi

Phukusi pa Phukusi kwenikweni ndi njira yopangira zida kapena ma IC (Integrated Circuits) pa boardboard.Monga njira yopangira ma phukusi, PoP imalola kuphatikizika kwa ma IC angapo mu phukusi limodzi, ndi malingaliro ndi kukumbukira pamaphukusi apamwamba ndi pansi, kuchulukitsa kachulukidwe kosungirako ndi magwiridwe antchito ndikuchepetsa malo okwera.PoP ikhoza kugawidwa m'magulu awiri: mawonekedwe okhazikika ndi mawonekedwe a TMV.Zomangamanga zokhazikika zimakhala ndi zida zomveka pansi paketi ndi zida zamakumbukiro kapena zokumbukiridwa papaketi yapamwamba.Monga mtundu wosinthidwa wa mawonekedwe a PoP, mawonekedwe a TMV (Kupyolera mu Mold Via) amazindikira kulumikizana kwamkati pakati pa chipangizo chanzeru ndi chokumbukira kudzera pabowo la phukusi lapansi.

Phukusi-pa-phukusi limaphatikizapo matekinoloje awiri ofunika: PoP yosungidwa kale ndi PoP yoyikidwa pa bolodi.Kusiyana kwakukulu pakati pawo ndi chiwerengero cha reflows: woyamba amadutsa reflows awiri, pamene otsiriza amadutsa kamodzi.

Ubwino wa POP

Ukadaulo wa PoP ukugwiritsidwa ntchito kwambiri ndi ma OEM chifukwa cha zabwino zake:

• Kusinthasintha - Kapangidwe ka Stacking ka PoP kumapereka ma OEMs masanjidwe angapo kotero kuti amatha kusintha magwiridwe antchito azinthu zawo mosavuta.

• Kuchepetsa kukula konse

• Kutsitsa mtengo wonse

• Kuchepetsa zovuta za boardboard

• Kupititsa patsogolo kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake

• Kupititsa patsogolo mulingo wogwiritsanso ntchito ukadaulo
