6 Inzira ENIG Binyuze muri-Pad PCB

1. Umwobo wacomeka urashobora kubuza PCB binyuze mumabati yo kugurisha umwobo uva mu mwobo unyuze hejuru yibice biterwa numuzunguruko mugufi;Nukuvuga ko, murwego rwo kugurisha umuraba wigishushanyo mbonera (muri rusange ubuso bwo gusudira ni 5mm cyangwa hejuru) nta mwobo cyangwa umwobo wo kuvura imiyoboro.

2. Umwobo ucomeka urinda imiyoboro migufi ishoboka iterwa nibikoresho byegeranye cyane nka BGA.Ninimpamvu yumwobo munsi ya BGA kugirango umwobo ugume mubikorwa.Kuberako nta mwobo ucomeka, uru ni ikibazo cyumuzunguruko muto.

3. Irinde ibisigisigi bya flux mu mwobo uyobora;

4. Nyuma yo guteranya no guteranya ibice byuruganda rwa elegitoroniki birangiye, PCB igomba kuba vacuum hamwe numuvuduko mubi wakozwe kumashini yipimisha mbere yo kurangiza:

5. Irinde kugurisha hejuru yububiko mu mwobo uterwa no gusudira, bigira ingaruka kubikorwa;Iyi ngingo iragaragara cyane muri padi yo gukwirakwiza ubushyuhe hamwe nu mwobo.

6. Kugira ngo wirinde kugurisha amabati y'amasaro, bikavamo uruziga rugufi.

7. Gucomeka umwobo bizafasha mubikorwa bya SMT.
