Kedu ihe bụ Mgbakọ BGA?
Mgbakọ BGA na-ezo aka na usoro ịgbanye bọọlụ Grid Array (BGA) na PCB site na iji usoro ịgbanye agbagharị. BGA bụ akụrụngwa etinyere n'elu nke na-eji ọtụtụ bọọlụ na-ere ere maka njikọ eletrik. Ka bọọdụ sekit na-agafe na oven reflow reflow, bọọlụ ndị a na-agbaze, na-eme njikọ eletrik.

Usoro mgbakọ BGA na-agụnyekarị usoro ndị a:
Nkwadebe PCB: A na-akwado PCB site n'itinye tapawa solder na paịlị ebe a ga-etinye BGA. Ihe nkedo na-ere ahịa bụ ngwakọta nke ihe na-eme ka ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ dị mma, nke na-enyere aka na usoro ịgbanye.
Ndokwa nke BGA: A na-etinye BGA, nke nwere mgbawa sekit agbakwunyere na bọọlụ na-ere ahịa na ala, na PCB a kwadebere. A na-emekarị nke a site na iji igwe na-anakọta ma ọ bụ ngwa mgbakọ ndị ọzọ.
Ịzụ ahịa nkwụghachi: PCB gbakọtara na BGA etinyebere na-agafe na oven reflow. Igwe ọkụ na-emegharị ahụ na-ekpo ọkụ PCB gaa n'otu okpomọkụ nke na-agbaze tapawa solder, na-eme ka bọọlụ ndị BGA na-agbapụta ma guzobe njikọ eletrik na paịlị PCB.
Ntụcha na nyocha: Mgbe usoro nrụgharị solder gasịrị, a na-eme ka PCB dị jụụ iji mee ka nkwonkwo solder sie ike. A na-enyocha ya maka ntụpọ ọ bụla, dị ka nhazighị nke ọma, mkpirisi, ma ọ bụ njikọ mepere emepe. Enwere ike iji nyocha nyocha anya akpaaka (AOI) ma ọ bụ nyocha X-ray maka ebumnuche a.
Usoro nke abụọ: Dabere na ihe ndị a kapịrị ọnụ, enwere ike ịme usoro ndị ọzọ dị ka ihicha, nnwale na mkpuchi conformal mgbe mgbakọ BGA gachara iji hụ na ntụkwasị obi na ịdị mma nke ngwaahịa emechara.

1. Obere akara ukwu
Nkwakọ ngwaahịa BGA nwere mgbawa, njikọta ọnụ, mkpụrụ dị mkpa na mkpuchi mkpuchi. Enwere ihe ole na ole ekpughere na ngwugwu ahụ nwere obere ntụtụ. N'ozuzu elu nke mgbawa na PCB nwere ike dị ka obere ka 1.2 millimeters.
2. Ike
Nkwakọ ngwaahịa BGA siri ike nke ukwuu. N'adịghị ka QFP nwere pitch 20mil, BGA enweghị atụdo nwere ike gbajie ma ọ bụ gbajie. N'ozuzu, iwepụ BGA chọrọ iji ọdụ ọrụ BGA na oke okpomọkụ.
3. Lower parasitic inductance na capacitance
Na obere ntụtụ na obere mgbakọ dị elu, nkwakọ ngwaahịa BGA na-egosipụta inductance parasitic dị ala na ikike, na-ebute arụmọrụ eletrik dị mma.
4. Enwekwu ohere nchekwa
Tụnyere ụdị nkwakọ ngwaahịa ndị ọzọ, nkwakọ ngwaahịa BGA nwere naanị otu ụzọ n'ụzọ atọ nke olu yana ihe dịka 1.2 ugboro mpaghara mgbawa. Ngwaahịa ebe nchekwa na arụ ọrụ site na iji nkwakọ ngwaahịa BGA nwere ike nweta ihe karịrị okpukpu 2.1 na ikike nchekwa yana ọsọ arụ ọrụ.
5. Nkwụsi ike dị elu
N'ihi nkwụsi ike nke pin si n'etiti mgbawa na nkwakọ ngwaahịa BGA, a na-ebelata ụzọ mgbasa ozi maka akara dị iche iche nke ọma, na-ebelata mbelata mgbaàmà yana melite ọsọ nzaghachi na ikike mgbochi. Nke a na-eme ka nkwụsi ike nke ngwaahịa ahụ dịkwuo elu.
6. Ezi ikpo ọkụ ọkụ
BGA na-enye arụmọrụ ikposa ọkụ dị mma, yana mgbawa okpomọkụ na-abịaru nso na ọnọdụ okpomọkụ n'oge ọrụ.
7. Dị mma maka ịrụgharị ọrụ
