Ukubuka Okubanzi Kwamaphakheji e-PLCC Ekukhiqizeni Amadivayisi Kagesi

Iphakheji ye-PLCC

Amaphakheji e-Plastic Leaded Chip Carrier (PLCC) adlala indima ebalulekile ekwenziweni kwemishini kagesi. Ngaphandle kokukhuphuka kwamaphakheji amasha e-IC njenge-QFP ne-BGA, ama-PLCC ahlala esebenza ezinhlelweni ezithile, ikakhulukazi ezinhlelweni zefa. Lesi sihloko sinikeza ukubuka konke okuphelele kwamaphakheji e-PLCC, ahlanganisa ukwakheka kwawo, izinhlobo, izinzuzo, izinhlelo zokusebenza, ukuxazulula izinkinga, nokulungisa.

Liyini Iphakheji le-PLCC?

Amaphakheji e-PLCC angamaphakheji e-surface-mount integrated circuit (IC) anomkhondo osuka kuzo zonke izinhlangothi ezine, aklanyelwe ukuthengiswa ku-PCB. Zinikeza umumo oyisikwele noma ongunxande futhi zingaqukatha noma yikuphi ukusuka kumaphini angama-20 kuye kwangaphezu kwama-84. Indawo engaphezulu ivamise ukufaka iwindi lokuhlola okubonakalayo kwe-IC.

Iphakheji ye-PLCC yethulwa njengendlela eqinile nethembekile kumaphakheji e-IC angaphambili. Ngokuhamba kweminyaka, ibone ukusetshenziswa okusabalele ezinhlelweni ezahlukahlukene, yize amaphakheji amasha afana ne-QFP ne-BGA adume kakhulu. Kodwa-ke, ama-PLCC asasetshenziswa emishinini endala ye-elekthronikhi nasezinhlelweni ezithile zesimanje lapho izici zawo ezihlukile zizuzisa.

Ukuklama Nokwakhiwa Kwamaphakheji we-PLCC
