Amabhodi wesifunda aphrintiwe asetshenziswa ku-elekthronikhi yanamuhla namadivayisi anezinto eziningi ze-elekthronikhi ezibekwe phezulu. Lokhu kuyiqiniso elibalulekile, njengoba inani lezinto ze-elekthronikhi ebhodini lesekethe eliphrintiwe liyanda, kanjalo nosayizi webhodi yesekethe. Kodwa-ke, usayizi webhodi lesekethe lokuphrinta, iphakethe le-BGA okwamanje liyasetshenziswa.

Nazi izinzuzo eziphambili zephakeji le-BGA okumele wazi ngalo kulokhu. Ngakho-ke, bheka imininingwane enikezwe ngezansi:

1. Iphakethe le-BGA elihlanganisiwe elinobuningi obuphezulu

I-BGAS ingesinye sezixazululo ezisebenza kahle kakhulu zenkinga yokwakha amaphakheji amancane ukuthola amasekethe ahlanganisiwe ahlanganisiwe aqukethe inani elikhulu lezikhonkwane. Amaphakeji we-Dual In-line Surface Surface kanye ne-PIN GRID ARRAY amaphakheji akhiqizwa ngokunciphisa ama-voids amakhulu wezikhonkwane anezikhala phakathi kwalezi zikhonkwane.

Ngenkathi lokhu kusetshenziselwa ukuletha amazinga aphezulu okubucayi, lokhu kwenza inqubo yezikhonkwane ezilungiselelwe kunzima ukuphatha. Lokhu kungenxa yokuthi ubungozi bokubopha izinhloko zezinhloko-kuya ezihlokweni kuyanda njengoba isikhala phakathi kwezikhonkwane siyancipha. Kodwa-ke, ukusheshisa kwe-BGA Iphakheji ingaxazulula le nkinga kangcono.

2. Ukushisa Ukushisa

Enye yezinzuzo ezimangalisa ngokwengeziwe zephakethe le-BGA yiyona encishisiwe yokumelana okushisayo phakathi kwe-PCB nephakheji. Lokhu kuvumela ukushisa okukhiqizwe ngaphakathi kwephakeji ukugeleza kangcono nomjikelezo ohlanganisiwe. Ngaphezu kwalokho, kuzovimba ne-chip ekushiseni ngokweqile ngendlela engcono kakhulu.

3. I-Untleckance ephansi

Abaqhubi abahle kakhulu, abafutshane abafushane basho ukuwohloka okuphansi. I-Inductance isici esingadala ukuhlanekezela okungafuneki kwamasiko e-speed electronic. Njengoba i-BGA iqukethe ibanga elifushane phakathi kwe-PCB nephakheji, liqukethe ukuhola okuphansi okuphansi, lizohlinzeka ngokwenza kangcono amadivayisi we-PIN.
