Tlhahlobo ea boto ea PCBAke mohato oa bohlokoa ho etsa bonnete ba hore boleng bo phahameng, botsitso bo phahameng, 'me lihlahisoa tsa PCBA tse ka tšeptjoang li fanoa ho bareki, ho fokotsa likoli matsohong a bareki, le ho qoba ka mor'a thekiso.Tse latelang ke mekhoa e mengata ea tlhahlobo ea boto ea PCBA:
- Tlhahlobo ea pono ，Tlhahlobo ea pono ke ho e sheba ka letsoho.Tlhahlobo ea pono ea kopano ea PCBA ke mokhoa oa khale ka ho fetisisa oa tlhahlobo ea boleng ba PCBA.Sebelisa mahlo feela le khalase e hōlisang ho hlahloba potoloho ea boto PCBA le soldering ea likarolo tsa elektronike ho bona hore na ho na le tombstone., Esita le marokho, thini e eketsehileng, hore na li-solder li kopantsoe ka borokho, ho sa tsotellehe hore na ho na le solder e nyenyane le e sa phethoang.'Me sebelisana le khalase e holisang ho bona PCBA
- In-Circuit Tester (ICT) ICT e ka tsebahatsa mathata a soldering le likarolo ho PCBA.E na le lebelo le phahameng, botsitso bo phahameng, hlahloba potoloho e khutšoanyane, potoloho e bulehileng, ho hanyetsa, bokhoni.
- Automatic optical inspection (AOI) ho lemoha kamano ea othomathike e fumaneha kantle ho marang-rang le marang-rang, hape e na le phapang lipakeng tsa 2D le 3D.Hajoale, AOI e tsebahala haholo femeng ea li-patch.AOI e sebelisa mokhoa oa ho lemoha litšoantšo ho hlahloba boto eohle ea PCBA le ho e sebelisa hape.Tshekatsheko ya data ya mochine e sebediswa ho fumana hore na boleng ba PCBA boto tjheseletsa.Khamera e hlahloba ka tsela e iketsang liphoso tsa boleng ba boto ea PCBA tlas'a teko.Pele ho tlhahlobo, hoa hlokahala ho fumana boto ea OK, le ho boloka lintlha tsa boto ea OK ho AOI.Tlhahiso ea bongata e ileng ea latela e thehiloe holim'a boto ena ea OK.Etsa mohlala oa motheo ho fumana hore na liboto tse ling li lokile.
- Mochini oa X-ray (X-RAY) Bakeng sa likarolo tsa elektroniki tse kang BGA/QFP, ICT le AOI ha li khone ho bona boleng ba ho soasoa ba liphini tsa bona tsa ka hare.X-RAY e tšoana le mochine oa X-ray oa sefuba, o ka fetang Hlahloba sebaka sa PCB ho bona hore na ho rekisoa ha lithapo tsa ka hare ho rekisoa, hore na ho behoa ho teng, joalo-joalo X-RAY e sebelisa X-rays ho phunyeletsa. boto ea PCB ho bona bokahare.X-RAY e sebelisoa haholo lihlahisoa tse nang le litlhoko tse phahameng tse ts'epahalang, tse ts'oanang le tsa Electronics tsa sefofane, lisebelisoa tsa elektroniki tsa likoloi.
- Tlhahlobo ea mohlala Pele tlhahiso ea boima le kopano, tlhahlobo ea pele ea mohlala e atisa ho etsoa, e le hore bothata ba bokooa bo tebileng bo ka qojoa ka tlhahiso ea bongata, e leng se lebisang mathateng a tlhahiso ea mapolanka a PCBA, a bitsoang tlhahlobo ea pele.
- Sesebelisoa se fofang sa sehlahlobi se fofang se loketse tlhahlobo ea li-PCB tse rarahaneng haholo tse hlokang litšenyehelo tse theko e phahameng tsa tlhahlobo.Moralo le tlhahlobo ea probe e fofang e ka phethoa ka letsatsi le le leng, 'me litšenyehelo tsa kopano li batla li le tlase.E khona ho hlahloba li-opens, li-shorts le mokhoa oa likarolo tse behiloeng ho PCB.Hape, e sebetsa hantle bakeng sa ho khetholla sebopeho sa likarolo le ho tsamaisana.
- Manufacturing Defect Analyzer (MDA) Sepheo sa MDA ke ho hlahloba boto feela ho senola liphoso tsa tlhahiso.Kaha boholo ba liphoso tsa tlhahiso ke litaba tse bonolo tsa khokahano, MDA e lekanyelitsoe ho lekanya tsoelo-pele.Ka tloaelo, tester e tla khona ho bona boteng ba li-resistors, capacitor, le transistors.Ho lemoha li-circuits tse kopantsoeng ho ka boela ha finyelloa ka ho sebelisa li-diode tsa tšireletso ho bontša ho behoa ha likarolo tse nepahetseng.
- Teko ea botsofali.Ka mor'a hore PCBA e be e ntse e eketseha le DIP post-soldering, sub-board trimming, tlhahlobo ea holim'a metsi le tlhahlobo ea pele, ka mor'a hore tlhahiso ea bongata e phethoe, boto ea PCBA e tla be e le tlas'a teko ea botsofali ho hlahloba hore na mosebetsi o mong le o mong o tloaelehile, likarolo tsa elektronike li tloaelehile, joalo-joalo.
