Ibyiza byo kugurisha BGA :

Ikibaho cyumuzingo cyacapishijwe gikoreshwa muri elegitoroniki yumunsi nibikoresho bifite ibikoresho byinshi bya elegitoronike byashizwe hamwe. Ibi ni ukuri kwingenzi, nkuko umubare wibikoresho bya elegitoronike ku kibaho cyacapwe cyiyongera, niko ubunini bwikibaho. Ariko, gusohora byacapishijwe ubunini bwumuzunguruko, paketi ya BGA irakoreshwa.

Dore ibyiza byingenzi bya pack ya BGA ugomba kumenya kuriyi ngingo. Noneho, reba amakuru yatanzwe hepfo:

1. BGA yagurishije paki ifite ubucucike bwinshi

BGAs nimwe mubisubizo bifatika kubibazo byo gukora udupaki duto twumuzunguruko wuzuye urimo umubare munini wa pin. Ibice bibiri kumurongo wubuso hamwe na pin grid array bipakurura birimo gukorwa mukugabanya icyuho Amajana ya pin hamwe n'umwanya uri hagati yibi pin.

Mugihe ibi bikoreshwa mukuzana urwego rwinshi, ibi bituma inzira yo kugurisha pin igoye gucunga. Ibi ni ukubera ko ibyago byo guhuza impanuka impanuka imitwe-imitwe yiyongera uko umwanya uri hagati yinini ugabanuka. Ariko, BGA Kugurisha paki birashobora gukemura neza iki kibazo.

2. Gutwara ubushyuhe

Imwe mu nyungu zitangaje za pake ya BGA nigabanuka ryumuriro hagati ya PCB na paki. Ibi bituma ubushyuhe butangwa imbere muri paki butemba neza hamwe nu muzunguruko. Byongeye kandi, bizarinda kandi chip gushyuha muburyo bwiza bushoboka.

3. Inductance yo hasi

Byiza cyane, amashanyarazi magufi asobanura inductance yo hasi. Inductance nikintu gishobora gutera kugoreka ibimenyetso bidakenewe mumashanyarazi yihuta. Kubera ko BGA irimo intera ngufi hagati ya PCB na paki, ikubiyemo induction yo hasi, izatanga imikorere myiza kubikoresho bya pin.
