Gahunda yumusaruro wa PCba irashobora kugabanywamo inzira nyinshi:

PCB igishushanyo n'iterambere → Gutunganya Pht Gutunganya → Dip Gucomeka → Ikizamini cya PCBA → Iteraniro rya gatatu zo kurwanya.

Ubwa mbere, Igishushanyo cya PCB niterambere

1.Ibicuruzwa

Gahunda runaka irashobora kubona agaciro runaka kumasoko iriho, cyangwa abakunzi bashaka kurangiza igishushanyo mbonera cyabo bwite, noneho ibyifuzo bihuye bizabyara;

2. Gushushanya no Gutezimbere

Ihujwe nibicuruzwa byabakiriya, inzara za R & D zizahitamo chip ya chip hamwe numuzunguruko uhuza igisubizo cyo kugera kubikorwa, iyi nzira irarebwa, ibirimo birimo hano bizamenyekana ukundi;

3, umusaruro wageragejwe

Nyuma yiterambere nigishushanyo mbonera cyabanjirije PCB, umuguzi azagura ibikoresho bihuye ukurikije bom itangwa niterambere ryabigenewe (10pcs.

Icya kabiri, gutunganya ibishishwa

Urukurikirane rwibikoresho bya SMT bigabanijwemo: Guteka Ibikoresho → Umugurisha Paste Kwinjira → SPI → Kungura → Kugarura Kugurisha Kugurisha → AOI → Gusana

1. Ibikoresho byiza

Kuri Chips, PCB, module nibikoresho byihariye byagiye bisinda amezi arenga 3, bigomba gutekwa saa 120 ℃ 24h. Kuri Microphone, amatara yayoboye nibindi bintu bitarwanya ubushyuhe bwo hejuru, bigomba gutekwa kuri 60 ℃ 24h.

2, Abacuruzi Paste (kugaruka ubushyuhe → Gukoresha → Gukoresha)

Kuberako umucuruzi wacu wabitswe mubidukikije bya 2 ~ 10 ℃ igihe kirekire, bigomba gusubizwa ubushyuhe bwikigero, kandi nyuma yubushyuhe bwo kugaruka, kandi nyuma yubushyuhe bwo kugaruka, bigomba gukurura ubushyuhe, hanyuma birashobora gucapa, hanyuma birashobora gucapwa, hanyuma birashobora gucapwa.

3. Kumenya SPI3D

Nyuma yumucuruzi Paste yacapwe ku kibaho cyumuzunguruko, PCB izagera ku mukandara wa spi binyuze mu mukandara wa convoyeur, kandi spi izabura umuvuduko, ubugari, uburebure bw'umucuruzi paste acapa no gusohora amabati.

4. Umusozi

Nyuma ya PCB itemba kuri mashini ya smt, imashini izahitamo ibikoresho bikwiye hanyuma uyashyire kuri numero zihuye binyuze muri gahunda yashyizweho;

5. Kubora

PCB yuzuyemo ibintu bitemba imbere yisumbuye, kandi inyura mu bushyuhe icumi bwintambwe kuva 148 ℃ kugeza 252 ℃ nacyo, bihuze neza, bihuze neza ibice byacu hamwe ninama ya PCB hamwe;

6, kumurongo wa Aoi

Aoi ni optique optique yikora, ishobora kugenzura ikibaho cya PCB hanze yitanura hejuru yubusobanuro bwikibaya, kandi niba hari ibikoresho bike bihujwe hagati yibice kandi niba tablet ihari.

7. Gusana

Ku bibazo biboneka ku kibaho cya PCB muri AOI cyangwa intoki, bigomba gusanwa na injeniyeri yo gufata neza, kandi ikibaho cya PCB cyoherezwa mu gico cya dip hamwe n'ikigo gisanzwe cya Offline.

Bitatu, ibibyimba byo gucomeka

Inzira yo Gucomeka igabanijwemo: Gutegura → Gucomeka → Kugabana Kugurisha

1. Kubaga plastique

Ibikoresho byo gucomeka twaguze byose nibikoresho bisanzwe, hamwe nuburebure bwibikoresho dukeneye biratandukanye, kugirango dukenera guhindura ibirenge byambere, kugirango uburebure bwibirenge bunoze gukora plug cyangwa gusudira.

2. Gucomeka

Ibice byuzuye bizashyirwamo ukurikije icyitegererezo gihuye;

3, umunwa ucuruza

Isahani yinjijwe ishyirwa kuri jig imbere yumuraba. Ubwa mbere, flux izaterwa hepfo kugirango igufashe gusudira. Iyo isahani igeze hejuru yitanura rya tin, amazi yamabati mu itanura azareremba hanyuma uhamagare PIN.

4. Kata ibirenge

Kuberako ibikoresho mbere byo gutunganya bizagira ibisabwa byihariye kugirango ushireho igice kinini, cyangwa ibikoresho ubwabyo ntabwo byoroshye gutunganya, PIN izahinduka uburebure bukwiye mugushushanya amakuru;

5. Gufata amabati

Hashobora kubaho ibintu bibi nkibintu bibi, Pinholes, yabuze gusudira, gusudira ibinyoma nibindi no mumapaki yinama yububiko bwa PCB nyuma itanura. TONTER YACU BAZizana no gusana intoki.

6. Koza Inama y'Ubutegetsi

Nyuma yo kugurisha umuraba, gusana hamwe nandi mahuza yimbere, hazabaho flux zisigaye cyangwa ibindi bicuruzwa byibwe bifatanye kumwanya wa PCB, bisaba ko abakozi bacu basukura hejuru;

7. Kugenzura ubuziranenge

PCB Ikibaho Ibigize Ikosa na cheque yatemba, Ubuyobozi butemewe bwa PC bukeneye gusanwa, kugeza igihe bujuje ibisabwa kugirango akomeze intambwe ikurikira;

4. Ikizamini cya PCBA

Ikizamini cya PCBA kirashobora kugabanywamo ikizamini cya ICT, ikizamini cya fct, ikizamini cyo gusaza, ikizamini cya vibration, nibindi

Ikizamini cya PCBA nikigeragezo kinini, ukurikije ibicuruzwa bitandukanye, ibisabwa bitandukanye byabakiriya, ikizamini gisobanura kiratandukanye. Ikizamini cya ICT nukumenya imiterere yo gusudira hamwe nimiterere yimirongo, mugihe ikizamini cya fct nukumenya ibyinjijwe hamwe nibipimo byinama yububiko bya PCBA kugirango bigenzure.

Bitanu: pcba batatu barwanya

PCBA itatu yo kurwanya inzira ni: koza uruhande A → Ubuso bwumye → Broushhing Uruhande B → Ubushyuhe bwicyumba Cyiza:

0.1mm-0.3mm6. Ibikorwa byose byo gukwirakwiza bigomba gukorwa ku bushyuhe butarenze 16 ℃ no gutesha agaciro ubushuhe munsi ya 75%. Pcba batatu barwanya baracyari byinshi, cyane cyane ubushyuhe nubushuhe byagati, bikaba, bitera intangarugero bya PCBA, BIKORWA, GUTANDUKANYE, GUTANGA MU BIKORWA BYA PCBA, BIKORWA BIKURIKIRA, GUHINDUKA HAMWE NUMUNZIJE. Uburyo bwo gutera nuburyo bukoreshwa cyane mu nganda.

Iteraniro ryarangiye

7.Ibicuruzwa bya PCBA hamwe nikizamini ok bigateranijwe kubisige, hanyuma imashini yose irashaje kandi igerageza, nibicuruzwa bitagira ibibazo byiyongera.

Umusaruro wa PCBA numuhuza kumurongo. Ikibazo icyo aricyo cyose mubikorwa bya PCBA bizagira ingaruka zikomeye kumico rusange, kandi buri nzira igomba kugenzurwa neza.
