Vagadziri vePCB vanogadzira sei PCB mhando?

Sezvo tekinoroji ichienderera mberi, akadhindwa edunhu mabhodhi (PCBs) ave zvikamu zvakakosha zvezvishandiso zvakawanda zvemagetsi. Kubva pamafoni emafoni kusvika kumidziyo yekurapa, maPCB anoita basa rakakosha mukuona kushanda kwakanaka kwemidziyo iyi. Naizvozvo, vagadziri vePCB musangano vanofanirwa kutevedzera kuyedza uye maitiro ekuongorora kuti vavimbise kunaka kwezvigadzirwa zvavo.Mune ino blog post, tichaongorora matanho akasiyana uye matanho anotorwa nevagadziri ava kuti tive nechokwadi chepamusoro-mhando maPCB.

Kutanga Kuona Kuongorora:

Nhanho yekutanga muhutano hwekutonga maitiro ndeyekutarisa kwekuona kwePCB. Vagadziri vePCB vanonyatsoongorora mabhodhi edunhu kune chero hurema hwemuviri hwakadai sekukwenya, mazino, kana kukuvara kwezvikamu. Kuongorora kwekutanga uku kunobatsira kuona chero nyaya dzinooneka dzinogona kukanganisa kuita kwePCB kana kuvimbika.

basa bvunzo:

Mushure mekunge kuongorora kwekutanga kwapera, mugadziri anoenderera mberi nekuedza kushanda. Danho iri rinosanganisira kuongorora mashandiro emagetsi ePCB nekuita bvunzo dzakasiyana siyana paPCB. Aya maedzo anosimbisa kuti PCB inoshanda sezvaitarisirwa uye inosangana nezvinodiwa. Kushanda kuyedzwa kunogona kusanganisira bvunzo dzakadai seyesimba-kumusoro kuyedzwa, bvunzo nzvimbo yekuwana, chiratidzo chekuvimbika kwekuongorora, uye muganhu wekuongorora.

Automated Optical Inspection (AOI):

Kuti tive nechokwadi chemhando uye huchokwadi hwemagungano ePCB, vagadziri vanowanzoshandisa maotomatiki optical inspection (AOI) masisitimu. AOI inoshandisa makamera ane gadziriso yepamusoro kutora mifananidzo yemaPCB akaungana. AI-inotyairwa software yobva yaenzanisa iyi mifananidzo nedhizaini yereferensi, ichizivisa chero mutsauko wakadai sekushaikwa kwezvikamu, kusarongeka kana kusarongeka. AOI inonatsiridza huroyi nekukasira kwekuongorora, uye inokwanisa kuona nyangwe kakanganiso kadiki-diki kangatadza kuitwa nekuongorora nemaoko.

X-ray kuongorora:

Kune maPCB akaomarara ane zvakavanzika kana zvisingaonekwe zvikamu, x-ray kuongorora kunogona kubatsira. Kuongororwa kweX-ray kunobvumira vagadziri kuti vaone kuburikidza nezvikamu zvePCB uye kuona chero hurema hunogona kuitika, senge mabhiriji ekutengesa kana ma voids. Iyi nzira yekuyedza isingaparadze inobatsira kuona zvinhu zvisingaonekwe nekutarisa kwekuona kana AOI, kuve nechokwadi chechimiro chekuvimbika uye kushanda kwePCB.

Muedzo wepamhepo (ICT):

In-circuit test (ICT) nderimwe danho rakakosha muhutano hwekutonga maitiro. Munguva yeICT maitiro, vagadziri vanoshandisa michina yakasarudzika kuongorora mashandiro ezvimwe zvikamu uye maseketi paPCB. Nekushandisa chaiyo voltages uye masaini, muyedzi anogona kuona chero kutadza kwechikamu, pfupi dunhu kana kuvhurika dunhu. ICT inobatsira kuona zvinhu zvisina kunaka kana zvinongedzo zvinogona kuita kuti PCB itadze kana kuita payakakwana.

Muedzo wekuchembera:

Kuti uongorore kuvimbika kwenguva refu uye kugadzikana kwePCBs, vagadziri vanowanzoita bvunzo dzekupisa pavari. Kupisa-mukuyedza kunosanganisira kufumura PCB kune tembiricha yepamusoro (kazhinji iri pamusoro penzvimbo yayo yekushandisa) kwenguva yakareba. Uku kuyedzwa kwakasimba kunobatsira kuona chero zvikanganiso zvingangoitika kana kushaya simba muchikamu uye inova nechokwadi chekuti PCB inogona kumirisana neyakajairwa mamiriro ekushanda pasina kukundikana.

Environmental testa

Sezvo maPCB achigona kukanganiswa neakasiyana mamiriro ezvakatipoteredza, zvakakosha kuti uedze kusimba uye kuita kwavo pasi pemamiriro akasiyana. Kuyedzwa kwezvakatipoteredza kunosanganisira kufumura maPCB kune yakanyanyisa tembiricha, humidity, vibration uye kuvhunduka. Iyi bvunzo inoongorora kuramba kwePCB kumamiriro akashata uye kuona kuti vanogona kumirisana nezvinodiwa zvemashandisirwo epasirese.

bvunzo yekupedzisira:

MaPCB asati atumirwa kune vatengi, vanoongororwa kwekupedzisira kuti vaone kuti vanozadzisa zvese zvinodiwa. Kuongorora uku kunosanganisira kunyatsoongorora chitarisiko chePCB, ukuru, kushanda kwemagetsi uye kushanda. Kunyatsoongorora kwekupedzisira kunoderedza mukana wekuti maPCB akaremara aunzwe kune vatengi, nekudaro achivimbisa emhando yepamusoro zviyero.

Mukupedzisa, vagadziri vePCB vanoitisa nhevedzano yekuyedza uye yekuongorora maitiro kuti vave nechokwadi chemhando yezvigadzirwa zvavo.Kuongorora kwemaziso, kuongorora kushanda, AOI, X-ray kuongorora, ICT, kupisa-mukuedza, kuongorora kwezvakatipoteredza uye kuongorora kwekupedzisira zvose zvinotora basa rinokosha mukugadzirisa kwehutano. Nekunyatsotevedzera maitiro aya, vagadziri vanogona kuona kuti maPCB avanoburitsa anosangana nezvinodiwa, nekudaro vachipa vatengi zvigadzirwa zvakavimbika uye zvemhando yepamusoro.
