Umwobo utwara neza ukoresheje umwobo uzwi kandi nkuko umwobo. Kugirango uhuze ibisabwa byabakiriya, ikibaho cyumuzunguruko ukoresheje umwobo kigomba gucomeka. Nyuma yimyitozo myinshi, inzira gakondo yo guhinduranya irahindurwa, kandi ikibaho cyumuzunguruko mask no gucomeka birangiye hamwe na mesh yera. umwobo. Umusaruro uhamye kandi ufite ubuziranenge.

Ukoresheje umwobo uhindura uruhare rwo guhuza no gukora imirongo. Iterambere ry'inganda za elegitoronike naryo riteza imbere iterambere rya PCB, kandi rinashyira imbere ibisabwa byinshi ku mikorere y'Inama y'Ubutegetsi no mu ikoranabuhanga ryo hejuru. Binyuze mu mwobo wo guhinduranya intoki zaje kubaho, kandi ugomba kuzuza ibisabwa bikurikira:

(1) Hariho umuringa mu mwobo, kandi maske y'umusirikare irashobora gucomeka cyangwa idacomeka;
.
.

Hamwe no guteza imbere ibicuruzwa bya elegitoroniki mu cyerekezo cy '"umucyo, binini, bigufi kandi bito", PCbs nayo yateye imbere mu bucucike bugufi kandi bigoye. Kubwibyo, umubare munini wa SMT na Bga bagaragaye, kandi abakiriya bakeneye gucomeka mugihe bigize ibice, harimo nibigize, birimo imirimo itanu:

. Cyane cyane iyo dushyize ikoresheje umwobo kuri Bga Pad, tugomba kubanza gukora umwobo womekaho hanyuma tugashyira ahagaragara zahabu kugirango tworohereze kugurisha.
(2) Irinde ibisiga bya flux mu mwobo;

Kumenyera imiyoboro iyobora

Ku kibaho hejuru yimbaho, cyane cyane kuzenguruka Bga na IC, imiyoboro ya Hole igomba kuba iringaniye, convex na convove wongeyeho cyangwa ukuyemo 1mil the via hole hides the tin ball, in order to reach customers According to the requirements, the via hole plugging process can be described as diverse, the process is particularly long, the process is difficult to control, and the oil is often dropped during the hot air leveling and the green oil solder resistance test; Ibibazo nkibiturika byamavuta nyuma yo gukiza. Ukurikije ibintu nyabyo byumusaruro, inzira zitandukanye zo gucomeka muri make, kandi kugereranya nibisobanuro nibisobanuro nibisobanuro nibibi:

Icyitonderwa: Ihame ryakazi ryinganda zishyushye ni ugukoresha umwuka ushushe kugirango ukureho umusirikare urenze hejuru no mu mwobo winama yumuriro wacapwe. Umugurisha usigaye yashizwemo neza kuri padi, imirongo yumurongo udashira hamwe nuburyo bupakira hejuru, nuburyo bwo kuvura hejuru yububiko bwumuzunguruko wacapweho.

1. Gucomeka neza nyuma yo kunganirwa

Inzira itemba ni: Ububiko bwamazimbere ya mask → Hal → Gucomeka umwobo → Gukiza. Inzira itari yo gucomeka yemejwe kumusaruro. Nyuma yumwuka ushyushye washyizwe ahagaragara, urupapuro rwa aluminium cyangwa ink guhagarika ecran ikoreshwa kugirango urangize ukoresheje imiyoboro iteganijwe numukiriya kubihome byose. Gucomeka Inyoni irashobora kuba wino ifotore cyangwa thermoseting wino. Muburyo bworoshye ibara rya firime itose rihoraho, ink yo gucomeka nibyiza gukoresha wino imwe nkiyibaho. Iyi nzira irashobora kwemeza ko ibyobo bitazatakaza amavuta nyuma yumwuka ushyushye, ariko biroroshye gutera umwobo wo gucomeka kugirango wanduze ubutaka kandi butaringaniye. Abakiriya bakunda kubagurisha ibinyoma (cyane cyane muri Bga) mugihe cyo kwiyongera. Abakiriya benshi rero ntabwo bemera ubu buryo.

2. Ihanga mu kirere gishyushye no gucomeka

2.1 Koresha urupapuro rwa Aluminum kugirango ucome, ushimangire, hanyuma wogoshe Inama y'Ubutegetsi kugirango wimure

Iyi nzira ikoresha imashini yo gucukura imibare kugirango ikore urutoki rwa aluminium akeneye gucomeka kugirango acomerwe kugirango akemure neza kugirango umenye neza ko ukoresheje umwobo wuzuye. Inkongi ya Plug wino irashobora kandi gukoreshwa hamwe no gutwika wino, kandi ibiranga bigomba gukomera. , Kugabanuka kwa resin ni nto, hamwe n'imbaraga zimurika nurukuta rwumwobo ni rwiza. Inzira Yumurongo ni: Mbere yo kuvura → Gucomeka umwobo → Gusya Plate → Ihererekanyabubasha → ETCHING → Mask yo hejuru

Ubu buryo burashobora kwemeza ko umwobo wo gucomeka unyuze kuri umwobo uringaniye, kandi ntihazabaho ibibazo byiza nko guturika kwa peteroli hamwe nigitonyanga cyamavuta kumwobo mugihe uringaniye umwuka ushushe. Ariko, iyi nzira isaba umwanya umwe wijimye wumuringa kugirango ugire umuringa wumuringa wurukuta rwurukuta rwumukiriya uhuye nibipimo byabakiriya. Kubwibyo, ibisabwa kugirango ibyorezo byumuringa byose ni byinshi cyane, kandi imikorere ya mashini yo gusya nayo iri hejuru, kugirango igaragaze ko resin iri hejuru yakuweho burundu, kandi hejuru yumuringa irasukuye kandi ntabwo yanduye. Inganda nyinshi za PCB ntabwo zifite umwanya umwe wijimye, kandi imikorere yibikoresho ntabwo yujuje ibisabwa, bikavamo imikoreshereze yiyi nzira munganda za PCB.

1. Gucomeka neza nyuma yo kunganirwa

Inzira itemba ni: Ububiko bwamazimbere ya mask → Hal → Gucomeka umwobo → Gukiza. Inzira itari yo gucomeka yemejwe kumusaruro. Nyuma yumwuka ushyushye washyizwe ahagaragara, urupapuro rwa aluminium cyangwa ink guhagarika ecran ikoreshwa kugirango urangize ukoresheje imiyoboro iteganijwe numukiriya kubihome byose. Gucomeka Inyoni irashobora kuba wino ifotore cyangwa thermoseting wino. Muburyo bworoshye ibara rya firime itose rihoraho, ink yo gucomeka nibyiza gukoresha wino imwe nkiyibaho. Iyi nzira irashobora kwemeza ko ibyobo bitazatakaza amavuta nyuma yumwuka ushyushye, ariko biroroshye gutera umwobo wo gucomeka kugirango wanduze ubutaka kandi butaringaniye.

Inoco yo gucomeka irashobora kandi gukoreshwa no muri thermoseting wino, kandi ibiranga hagomba gukomera. Inzira Yumurongo ni: Mbere yo kuvura → Gucomeka umwobo → Gusya Plate → Ihererekanyabubasha → ETCHING → Mask yo hejuru

Ubu buryo burashobora kwemeza ko umwobo wo gucomeka unyuze kuri umwobo uringaniye, kandi ntihazabaho ibibazo byiza nko guturika kwa peteroli hamwe nigitonyanga cyamavuta kumwobo mugihe uringaniye umwuka ushushe. Ariko, iyi nzira isaba umwanya umwe wijimye wumuringa kugirango ugire umuringa wumuringa wurukuta rwurukuta rwumukiriya uhuye nibipimo byabakiriya. Kubwibyo, ibisabwa kugirango ibyorezo byumuringa byose ni byinshi cyane, kandi imikorere ya mashini yo gusya nayo iri hejuru, kugirango igaragaze ko resin iri hejuru yakuweho burundu, kandi hejuru yumuringa irasukuye kandi ntabwo yanduye. Inganda nyinshi za PCB ntabwo zifite umwanya umwe wijimye, kandi imikorere yibikoresho ntabwo yujuje ibisabwa, bikavamo imikoreshereze yiyi nzira munganda za PCB.

2.2 Nyuma yo gucomeka umwobo hamwe nurupapuro rwa aluminium, mu buryo butaziguye-icapiro

Iyi nzira ikoresha imashini yo gucukura CNC kugirango ikore urutoki rwa Aluminum akeneye gucomeka kugirango acomere ya ecran kugirango ashyireho umwobo, hanyuma akayihagarika kurenga gucomeka, no gukoresha 30t ecran kugirango ugaragaze neza hejuru yikibaho. Inzira Yumurongo ni: Pretreatment-Plug Hole-Silk Mugaragaza-Guteka-Gutanga-Gukura-Gukiza

Iyi nzira irashobora kwemeza ko ukoresheje umwobo utwikiriwe namavuta, umwobo womekaho uraringaniye, kandi ibara rya firime ritose rihamye. Nyuma yumwuka ushushe urambuye, birashobora kwemeza ko ukoresheje umwobo utarangwa kandi amasaro ya tin ntabwo yihishe mu mwobo, ariko biroroshye gutera wino mu mwobo nyuma yo gukiza indangagaciro zidahwitse; Nyuma yumwuka ushyushye washizweho, impande za vias bubbling namavuta akurwaho. Biragoye kugenzura umusaruro hamwe nuburyo bwo gutunganya, hamwe na injeniyeri zitunganya zigomba gukoresha inzira zidasanzwe nibipimo kugirango ireme ryimiterere yimyobo.
