Ho utloisisa Quad Flat Package (QFP) Technology

Quad Flat Package (QFP) ke theknoloji ea holim'a metsi (SMT) e sebelisetsoang li-circuits tse kopantsoeng tsa matlo (ICs). E khetholloa ka sebopeho sa eona se bataletseng, se khutlonnetsepa se nang le loto ho tloha mahlakoreng a mane, hangata ho thoeng ke "gull-wing" lead. Tsena li tsamaisa ho tsamaisa tšebetso ea solder le ho fana ka botsitso ba mochini ha sephutheloana se behiloe ho PCB. Kamohelo e atileng ea QFP liindastering tse fapaneng - ho tloha ho lisebelisoa tsa elektroniki ho isa ho lisebelisoa tsa puisano - e tsamaisitsoe ke ho feto-fetoha ha eona, ho kopana, le tšebeliso e ntle ea sebaka ho PCB.

Liphutheloana tsa QFP li fana ka mefuta e mengata ea lits'ebetso tse hlokang lipalo tse itekanetseng ho isa ho tse phahameng. Tsena li kenyelletsa li-microcontroller, li-processor, li-memory chips, le li-IC tse ling tse ngata. Litlhophiso tse tloaelehileng tsa QFP li fapana ho ea ka palo ea lithakhisa, pitch pitch (sebaka se pakeng tsa li-lead tse haufi), le boholo ba liphutheloana, ho lumella baenjiniere ho khetha QFP e loketseng litlhoko tsa bona tse khethehileng.
