Gahunda yo gukora inteko ya PCB

PCBA bivuga inzira yo gushiraho, kwinjiza no kugurisha ibice bya PCB byambaye ubusa.Umusaruro wa PCBA ukeneye kunyura murukurikirane rwibikorwa kugirango urangize umusaruro.Noneho, PCBFuture izamenyekanisha inzira zitandukanye zumusaruro wa PCBA.

Gahunda yo kubyaza umusaruro PCBA irashobora kugabanywamo inzira nyinshi zingenzi, gutunganya ibicuruzwa bya SMT → DIP plug-in gutunganya → Ikizamini cya PCBA → guteranya ibicuruzwa byarangiye.

Ubwa mbere, SMT ihuza gutunganya

Inzira yo gutunganya chip ya SMT ni: kugurisha paste ivanze → kugurisha paste icapiro → SPI → gushiraho → kwerekana ibicuruzwa → AOI → rework

1, kugurisha paste kuvanga

Nyuma yo kugurisha paste yo kugurisha muri firigo hanyuma igashonga, ikangurwa nintoki cyangwa imashini kugirango icapwe kandi igurishwe.

2, kugurisha ibicuruzwa

Shira paste yuwagurishije kuri stencil, hanyuma ukoreshe igikanda kugirango wandike paste yuwagurishije kuri padi ya PCB.

3, SPI

SPI niyagurisha paste yubugari, ishobora gutahura icapiro ryabacuruzi no kugenzura ingaruka zo gucapa paste.

4. Kuzamuka

Ibice bya SMD bishyirwa kuri federasiyo, kandi umutwe wimashini ushyira ushyira neza ibice kuri federasiyo kuri PCB ukoresheje indangamuntu.

5. Kugaragaza kugurisha

Genda unyuze ku kibaho cya PCB unyuze mu kugurisha ibicuruzwa, hanyuma paste imeze nk'umugurisha ushushe ushushe mumazi ukoresheje ubushyuhe bwinshi imbere, hanyuma ukonje kandi ushikamye kugirango urangize kugurisha.

6.AOI

AOI ni igenzura ryikora ryikora, rishobora kumenya ingaruka zo gusudira ku kibaho cya PCB ukoresheje scanne, kandi ukamenya inenge zubuyobozi.

7. gusana

Sana inenge zagaragajwe na AOI cyangwa ubugenzuzi bwintoki.

Icyakabiri, DIP icomeka mugutunganya

Inzira yo gutunganya ibyuma bya DIP ni: gucomeka → kugurisha imiraba → gukata ikirenge → inzira yo gusudira → ikibaho cyo gukaraba inspection kugenzura ubuziranenge

1, icomeka

Tunganya amapine y'ibikoresho byacometse hanyuma ubishyire ku kibaho cya PCB

2, kugurisha umuraba

Ikibaho cyinjijwemo kigurishwa.Muri ubu buryo, amabati y'amazi azaterwa ku kibaho cya PCB, hanyuma akonje kugirango arangize kugurisha.

3, gukata ibirenge

Amapine yikibaho yagurishijwe ni maremare kandi akeneye gukosorwa.

4, gutunganya gusudira

Koresha amashanyarazi yo kugurisha amashanyarazi kugurisha intoki ibice.

5. Karaba isahani

Nyuma yo kugurisha imiraba, ikibaho kizaba cyanduye, ugomba rero gukoresha amazi yo gukaraba hamwe nigikoresho cyo kumesa kugirango ubisukure, cyangwa ukoreshe imashini kugirango usukure.

6, kugenzura ubuziranenge

Kugenzura ikibaho cya PCB, ibicuruzwa bitujuje ibyangombwa bigomba gusanwa, kandi ibicuruzwa byujuje ibisabwa ni byo byonyine bishobora kwinjira mu nzira ikurikira.

Icya gatatu, ikizamini cya PCBA

Ikizamini cya PCBA kirashobora kugabanwa mubizamini bya ICT, ikizamini cya FCT, ikizamini cyo gusaza, ikizamini cya vibrasiya, nibindi.

Ikizamini cya PCBA nikizamini kinini.Ukurikije ibicuruzwa bitandukanye nibisabwa abakiriya batandukanye, uburyo bwikizamini bwakoreshejwe buratandukanye.

Icya kane, guteranya ibicuruzwa

Ikibaho cya PCBA cyageragejwe giteranyirizwa hamwe, hanyuma kirageragezwa, amaherezo kirashobora koherezwa.

Umusaruro wa PCBA ni umuhuza umwe umwe.Ikibazo icyo aricyo cyose mumurongo uwo ariwo wose kizagira ingaruka nini kumiterere rusange, kandi birakenewe kugenzura neza buri gikorwa.
