Ichi chinyorwa chinokupa iwe sumo yakazara yePCB redunhu bhodhi rekubika maitiro zvinodiwa uye simba-rekuponesa kurudziro.Nekuwedzera kuri kuita dambudziko resimba repasi rose uye kusimbaradzwa kwemitemo yezvakatipoteredza, vagadziri vePCB vakaisa pamberi pepamusoro zvinodiwa padanho rekuchengetedza simba remidziyo.Kubika idanho rakakosha muPCB kugadzira maitiro.Kazhinji kushandiswa kunopedza huwandu hwakawanda hwemagetsi.Naizvozvo, kusimudzira midziyo yekubikira kuvandudza kuchengetedza kwesimba yave imwe yenzira dzePCB board vagadziri kuchengetedza simba uye kuderedza mutengo.
Iyo yekubikira maitiro inenge ichimhanya kuburikidza neyese maitiro ePCB redunhu bhodhi kugadzirwa.Izvi zvinotevera zvinokuzivisa iwe kubike process zvinodiwa zvePCB redunhu bhodhi kugadzirwa.
1. Matanho ekugadzirisa anodiwa pakubheka mabhodhi ePBC
1. Lamination, exposure, and browning mukugadzirwa kweinner layer panels zvinoda kupinda muimba yekuomesera yekubheka.
2. Kutarisa, kupeta uye kugaya mushure mekucheka kunodiwa kuti ubvise unyoro, kunyunguduka uye kushushikana kwemukati, kudzikamisa chimiro uye kuwedzera kunamatira, uye kunoda kurapwa kwekubheka.
3. Mhangura yekutanga mushure mekuchera inoda kubikwa kuti ikurudzire kugadzikana kwemaitiro e electroplating.
4. Pre-therapy, lamination, exposure and development in outer layer production zvose zvinoda kubika kupisa kutyaira kemikari kugadzirisa kugadzirisa zvinhu uye kugadzirisa migumisiro.
5. Kudhinda, pre-kubika, kufumurwa, uye kuvandudza pamberi solder mask inoda kubheka kuve nechokwadi kugadzikana uye kunamatira kweiyo solder mask zvinhu.
6. Pickling uye kudhinda pamberi pekunyora zvinyorwa zvinoda kubheka kusimudzira maitiro emakemikari uye kugadzikana kwezvinhu.
7. Kubika mushure mekurapa kwepamusoro kweOSP kwakakosha pakugadzikana uye kunamatira kwezvinhu zveOSP.
8. Inofanira kubikwa isati yaumbwa kuti ive nechokwadi chekuoma kwezvinhu, kuvandudza kunamatira nezvimwe zvinhu, uye kuve nechokwadi chekuumba.
9. Pamberi pekuongorora kubhururuka kweprobe, kuitira kuti udzivise maitiro enhema uye kusarura kunokonzerwa nekukanganiswa kwehunyoro, kubika kubika kunodiwawo.
10. Kubika kurapwa pamberi peFQC kuongororwa ndeyekudzivirira unyoro pamusoro pepamusoro kana mukati mePCB board kubva pakuita kuti bvunzo dzive dzisina kururama.
2. Kubika kunowanzo kukamurwa kuita nhanho mbiri: kubikira kwepamusoro-tembiricha uye kudzika-kupisa kubheka:
1. Kupisa kwekubikira kwepamusoro-soro kunowanzodzorwa kunosvika 110°C, uye nguva yacho inenge maawa 1.5-4;
2. Kudzikira-tembiricha yekubheka kunowanzo kudzorwa kuma70°C, uye nguva yacho yakareba semaawa 3-16.
3. Munguva yePCB redunhu bhodhi rekubikira, inotevera yekubikira uye yekuomesa michina inoda kushandiswa:
Yakatwasuka, ine simba-inochengetedza mugero ovheni, yakazara otomatiki kutenderera inosimudza yekubikira mutsara wekugadzira, infrared tunnel oveni uye zvimwe zvakadhindwa PCB wedunhu bhodhi ovheni michina.
Mhando dzakasiyana dzePCB oven midziyo inoshandiswa kune zvakasiyana-siyana zvekubikira zvinodiwa, senge: PCB board gomba plugging, solder mask screen kudhinda kubheka, izvo zvinoda hombe-vhoriyamu otomatiki mashandiro.Mavheni anochengetedza magetsi evhavha anowanzo shandiswa kuchengetedza simba rakawanda revashandi uye zviwanikwa zvezvinhu uku uchiwana kugona kwakanyanya.Kushanda kwekubika kunoshanda, kukwirira kwekupisa uye simba rekushandisa simba, hupfumi uye hushamwari hwezvakatipoteredza, hunoshandiswa zvakanyanya mudhipatimendi redunhu rebhodhi indasitiri kune solder mask pre-kubika uye zvinyorwa post-kubika yePCB mabhodhi;chechipiri, inonyanya kushandiswa kubheka uye kuomeswa kwePCB bhodhi mwando uye kushushikana kwemukati.Iyo yakatwasuka inopisa yemhepo inotenderera oveni ine yakaderera mutengo wemidziyo, diki tsoka uye yakakodzera kune akawanda-layer flexible baking.
4. PCB redunhu bhodhi kubika mhinduro, oveni midziyo yekurumbidza:
Kupfupisa, itsika isingadzivisike kuti PCB wedunhu bhodhi vagadziri vane yepamusoro uye yepamusoro zvinodiwa kune simba-rekuchengetedza mazinga emidziyo.Iyo igwara rakakosha kwazvo rekuvandudza mazinga ekuchengetedza simba, kuchengetedza mari uye kugadzirisa kugadzirwa kwekugadzira kuburikidza nekusimudzira kana kutsiva yekubikira michina.Mavheni anochengetedza magetsi evhavha ane zvakanakira kuchengetedza simba, kuchengetedza kwezvakatipoteredza, uye kushanda kwakanyanya, uye parizvino ari kushandiswa zvakanyanya.Chechipiri, mahovhoni anopisa emhepo anotenderera ane zvakasarudzika mumabhodhi ePCB epamusoro anoda kubikwa kwepamusoro uye kuchena senge IC inotakura mabhodhi.Mukuwedzera, ivo vanewo infrared rays.Tunnel furnaces nemimwe midziyo yeovheni parizvino yakura kuomesa nekurapa mhinduro.
Semutungamiri mukuchengetedza simba, Xinjinhui inoramba ichigadzira uye kuita shanduko inoshanda.Muna 2013, kambani yakatanga chizvarwa chekutanga chePCB chinyorwa post-baking tunnel-type yekudhinda oven tunnel oveni, iyo yakavandudza kuchengetedza kwesimba ne20% zvichienzaniswa nemidziyo yechinyakare.Muna 2018, kambani yakawedzera chizvarwa chechipiri chePCB post-baking tunnel oveni, iyo yakawana kukwidziridzwa kwe35% mukuchengetedza simba zvichienzaniswa nechizvarwa chekutanga.Muna 2023, nekubudirira kutsvagisa nekusimudzira kweakawanda ekugadzira patent uye matekinoroji ehunyanzvi, danho rekuchengetedza simba rekambani rakawedzera kusvika makumi mashanu neshanu muzana kana zvichienzaniswa nechizvarwa chekutanga, uye rakafarirwa nemakambani mazhinji epamusoro zana muPCB. indasitiri, kusanganisira Jingwang Electronics.Makambani aya akakokwa naXin Jinhui kuti ashanyire uye ataurirane nevemafekitori ekuyedza mapaneru.Mune ramangwana, Xinjinhui ichavhurawo mimwe michina yemhando yepamusoro.Ndapota rambai makatarisa, uye munogamuchirwawo kutifonera kuti titaurirane uye toita nguva yekutishanyira kuti titaurirane chiso nechiso.
