Musika wemagetsi emotokari ndiyo yechitatu yakakura kwazvo nzvimbo yekushandisa yePCBs mushure memakomputa uye kutaurirana. Sezvo mota dzakashanduka zvishoma nezvishoma kubva muzvigadzirwa zvemichini nenzira yechinyakare kuita zvigadzirwa zvemhando yepamusoro zvine hungwaru, ruzivo, uye mechatronics, tekinoroji yemagetsi yakashandiswa zvakanyanya mumotokari, ingave iri injini system kana chassis system, zvigadzirwa zvemagetsi ndizvo. inoshandiswa mukuchengetedza masisitimu, masisitimu eruzivo, uye mukati-mumotokari nharaunda masisitimu. Musika wemotokari wakanyatso kuve imwe nzvimbo inopenya mumusika wemagetsi evatengi. Kuvandudzwa kwemagetsi emotokari kwagara kwaita kuti kuvandudzwa kwePCB dzemotokari.
Mumazuva ano makiyi ekunyorera maPCB, mota dzePCB dzinotora chinzvimbo chakakosha. Nekudaro, nekuda kwenzvimbo yakakosha yekushanda, kuchengetedzeka uye zvakakwirira zvinodikanwa zvemotokari, zvinodiwa paPCB kuvimbika uye kuchinjika kwezvakatipoteredza zvakakwirira, uye mhando dzePCB tekinoroji inobatanidzwa zvakare yakakura. Iyi inyaya hombe kumakambani ePCB. Matambudziko; uye kune vagadziri vanoda kuvandudza musika wePCB wemotokari, kunzwisisa kwakawanda uye kuongororwa kwemusika mutsva uyu kunodiwa.
Mota PCBs inosimbisa kuvimbika kwepamusoro uye yakaderera DPPM. Saka, kambani yedu ine kuunganidza tekinoroji uye ruzivo mukugadzira-kuvimbika kwekugadzira? Zvinoenderana here neramangwana rekuvandudza chigadzirwa gwara? Panyaya yekutonga kwemaitiro, zvinogona kuitwa zvinoenderana nezvinodiwa zveTS16949? Yawana DPPM yakaderera here? Zvose izvi zvinoda kunyatsoongororwa. Kungoona iri keke rinoyedza uye nekuripinda neupofu zvinokonzeresa kukuvadza kune iyo bhizinesi pachayo.
Izvi zvinotevera zvinopa chikamu chinomiririra chemamwe maitiro akakosha mukugadzirwa kwemakambani emotokari ePCB panguva yekuyedzwa kwevazhinji vePCB vatinoshanda navo kuti vatarise:
1. Secondary test method
Vamwe vagadziri vePCB vanotora "secondary test method" yekuvandudza mwero wekutsvaga mabhodhi akaremara mushure mekutanga kuparara kwemagetsi.
2. Bad board foolproof test system
Vagadziri vePCB vanowanda vakaisa "yakanaka bhodhi yekumaka system" uye "yakaipa bhodhi kukanganisa-bhokisi bhokisi" mumuchina wekuona bhodhi rekuyedza kudzivirira zvinobudirira kudonha kwevanhu. Iyo yakanaka bhodhi yekumaka sisitimu inomaka yakaedzwa PASS bhodhi yemuchina wekuyedza, iyo inogona kunyatso kudzivirira bhodhi rakaedzwa kana bhodhi rakashata kuti riyerere mumaoko evatengi. Bhokisi rakashata rekukanganisa bhokisi bhokisi nderokuti panguva yekuedzwa, apo PASS board inoedzwa, test system inobudisa chiratidzo chokuti bhokisi rinovhurwa; kana zvisina kudaro, kana bhodhi rakashata richiedzwa, bhokisi rakavharwa, richibvumira mutyairi kuti aise bhodhi rakaedzwa zvakanaka.
3. Gadzira PPm yehutano system
Parizvino, iyo PPm (Partspermillion, zvikamu pamiriyoni yekuremara mwero) yemhando yepamusoro yakashandiswa zvakanyanya muPCB vagadziri. Pakati pevatengi vazhinji vekambani yedu, mashandisirwo uye zvakaitwa neHitachi ChemICal muSingapore ndizvo zvakanyanya kukodzera kutaurwa. Mufekitori, mune vanhu vanodarika makumi maviri vane basa rekuongororwa kwenhamba dzepamhepo PCB hunhu husina kujairika uye PCB yemhando yekudzoka. Uchishandisa nzira yekuongorora yenhamba yeSPC yekugadzira maitiro, bhodhi rega rega rakaputswa uye imwe neimwe yakadzoserwa yakaremara bhodhi inorongedzerwa kuongororwa kwenhamba, uye yakasanganiswa nemicro-slicing uye mamwe maturusi ekubatsira kuongorora magadzirirwo ekugadzira bhodhi rakashata uye rakaremara rinogadzirwa. Zvinoenderana nemhedzisiro yedata data, nemaune kugadzirisa matambudziko mukuita.
4. Kuenzanisa bvunzo nzira
Vamwe vatengi vanoshandisa mamodheru maviri emhando dzakasiyana kuyedza kuenzanisa mabheji ePCB, uye vanoteedzera iyo PPm yemabhechi anoenderana, kuitira kuti vanzwisise mashandiro emichina miviri yekuyedza, vobva vasarudza muchina wekuyedza kuita zvirinani kuyedza maPCB emotokari. .
5. Kuvandudza bvunzo parameters
Sarudza yakakwirira bvunzo paramita kuti unyatso kuona maPCB akadaro. Nekuti, kana ukasarudza yakakwira voltage uye chikumbaridzo, wedzera huwandu hweyakakwira-voltage kuverenga inodonha, inogona kuvandudza mwero wekuona wePCB isina kukwana board. Semuenzaniso, kambani hombe yeTaiwanese PCB muSuzhou yakashandisa 300V, 30M, uye 20 Euros kuedza maPCB emotokari.
6. Nguva nenguva ongorora ma parameter emuchina wekuyedza
Mushure mekushanda kwenguva refu kwemuchina wekuyedza, iyo yemukati kuramba uye mamwe ane hukama bvunzo ma paramita anozotsauka. Naizvozvo, zvinodikanwa kuti nguva nenguva ugadzirise ma paramita emuchina kuti ive nechokwadi cheiyo bvunzo paramita. Midziyo yekuyedza inochengetwa muchikamu chikuru chemabhizimusi makuru ePCB kwehafu yegore kana gore, uye maparamita emukati ekuita anogadziriswa. Kutsvaga "zero defect" maPCB emotokari kwagara kuri kutungamira kwekuedza kweruzhinji rwevanhu vePCB, asi nekuda kwekushomeka kwemidziyo yekushandisa uye zvigadzirwa, makambani epamusoro zana ePCB munyika achiri kungogara achitsvaga nzira. kuderedza PPm.
