Nhanganyaya kune yechinyakare PCB Assembly urongwa

Iyo yakakosha pcb chikamu (chinowanzozivikanwa sePCBA) inoitwa nenzira inotevera.

Kushanda kwesoda pasita: isa solder yekunamatira zvidimbu zvakasanganiswa nekubuda kune yepasi ndiro yePCB. Shandisa matemplate ehukuru hwakasiyana uye maumbirwo kuti uve nechokwadi chekuti kunama kunongoshandiswa panzvimbo dzakananga.

L Chinhu chinomisikidzwa: nemaoko kana otomatiki isa zvidiki zvemagetsi zvemudunhu pane iyo solder yekunamatira ndiro yekushandisa nekutora nekuburitsa otomatiki mashandiro.

L Reflow: kurapa kwesoder paste kunoitwa panguva yekuratidzira. Pfuura pcb bhodhi ine chinhu chakaisirwa kuburikidza neflow choto ine tembiricha inopfuura 500 ° F. Kana pasoda yanyungudika yanyungudika, inodzoserwa kune inotakura uye inosimbiswa nekuiisa kune inotonhorera.

L Kuongorora: Izvi zvinoitwa mushure mekuwedzeredza kuwedzeredza. Ita macheki kuti uone kushanda kwechikamu. Iyi nhanho yakakosha nekuti inobatsira kuona zvisizvo zvisirizvo, kubatana kwakashata, uye maseketi mapfupi. Kazhinji, kuiswa zvisizvo kunoitika panguva ye Reflux. Vagadziri vePCB vanoshandisa kuongorora kwemanyorerwo, X-ray kuongorora uye otomatiki oparesheni yekuongorora panguva ino.

Kupfuura-gomba chikamu chekuisa: Mazhinji wedunhu mabhodhi anoda zvese zviri zviviri kuburikidza-gomba uye pamusoro-pegomo zvinhu zvekuiswa. Naizvozvo, iwe waitwa mune ino nhanho. Kazhinji, kuburikidza-gomba kuisa kunoitwa uchishandisa wave soldering kana manyore kutema.

L Kuongorora kwekupedzisira uye kuchenesa: Pakupedzisira, tarisa kugona kwePCB nekuyedza pane akasiyana mafungu uye ma voltages. Kana iyo pcb ikapfuura nhanho iyi yekutarisa, ichenese nemvura yakashongedzwa, sekuwisira kuchasiya zvimwe zvisaririra. Mushure mekushambidza, inoomeswa pasi pemhepo yakamanikidzwa uye yakarongedzwa zvakanaka.

Izvi zvinotevera zvetsika pcb gungano maitiro. Sezvinoratidzwa, mazhinji ePCBS akaunganidzwa achishandisa–govhu teknolojia (THT), pamusoro-pegomo tekinoroji (SMT), uye masystem musangano maitiro. These PCBA processes will be discussed further.

Kuburikidza neHole Technology Musangano (THT): Sumo kumatanho anobatanidzwa

Kuburikidza neburi tekinoroji (THT) inosiyana chete mumatanho mashoma ePCBA. Ngatikurukurei THA yePCBA nhanho.

L Chikamu chekuisa: Munguva iyi maitiro, zvikamu zvinoiswa nemaoko nemainjiniya ane ruzivo. The installation process of manually picking up and placing components requires maximum precision and speed to ensure the placement of components. Mainjiniya anofanirwa kutevera zviyero zveTT nemirau kuti vabudirire mushe.

L Kuongorora uye calibration yezvinhu: Pcb mabhodhi anoenderana kugadzira dhizaini mafuremu kuve nechokwadi chakaringana kuiswa kwezvikamu. Kana paine kusarongeka kwenzvimbo kwakawanikwa, kunogadziriswa ipapo chete. Kuenzanisa kuri nyore pamberi pesimbi, saka zvinoriumba zvinogadziriswa panguva ino.

Wave soldering: MuTTT, wave soldering inoitwa kuti isimbise paste nekuchengetedza gungano rakamira munzvimbo yaro chaiyo. Mune wave soldering, iyo PCB ine chinhu chakasungirirwa chinofamba pamusoro peinononoka-inofamba mvura solder iyo inopisa pamatembiricha ari pamusoro pe500 ° F. Iyo inozoratidzwa kune inotonhorera kuti isimbise kubatana.

Surface Mount Technology musangano (SMT): Ndeapi matanho akasiyana akabatanidzwa

Matanho ePCBA ekutevera musangano reSMT anotevera:

Kushanda / kudhinda kwesoda pasita: isa pasoda pasita kune iyo ndiro kuburikidza neiyo solder yekunamatira purinda, uchireva dhizaini dhizaini. Izvi zvinova nechokwadi chekuti solder paste inodhindwa muhuwandu hunogutsa pane yakapihwa nzvimbo.

L Chikamu chinoiswa: Chikamu chinoiswa muzvinhu zveSMT zvinongoerekana zvaitika. Dunhu redunhu rinotumirwa kubva kuprinta kuenda kugungano regungano uko gungano rinotorwa nekuiswa ne otomatiki mechikari kutora uye kudonhedza michina. Unyanzvi uhu hunochengetedza nguva uchienzaniswa neyakaitwa manyorerwo, uye zvakare unoona kurongeka munzvimbo dzenzvimbo.

L Reflow soldering: Mushure mekunge gungano raiswa, PCB inoiswa muchoto uko pasita pasita inonyungudika uye ndokuiswa kwakatenderedza gungano. Iyo PCB inopfuura nepakati peinotonhorera kuti ibate chinhu chacho panzvimbo.

Pamusoro pegomo tekinoroji (SMT) inoshanda zvakanyanya mumatambudziko ePCB gungano maitiro.

Nekuda kwekuwedzera kuomarara kwemidziyo yemagetsi uye dhizaini yePBB, mhando dzemusangano dzakauchikwa dzinoshandiswawo muindasitiri. Kunyangwe, sekureva kunoita zita, iyo yakasanganiswa pcb gungano maitiro mubatanidzwa weTTT uye SMT.
