Kuyang'anira Ubwino / Kuyesa
Kuyesa kwa PCB kumachita mayeso osiyanasiyana pama board osindikizidwa kuti atsimikizire mtundu wawo ndi momwe amagwirira ntchito, kuwonetsetsa kuti zolakwika zilizonse kapena zovuta zomwe zingachitike panthawi yopanga, ndikuwonetsetsa kuti zitha kukwaniritsa zofunikira ndi magwiridwe antchito, ndikuwongolera magwiridwe antchito ndikuchepetsa ndalama.Mtengo womaliza.
Titha kupereka ntchito zosiyanasiyana zoyesa za PCB, kuphatikiza:
Kuyang'ana pamanja/Zowoneka:Takhala ndi owunikira a PCB omwe amaphatikiza zowunikira pamanja pamayesero angapo kuti tiwonetsetse kuti ma PCB amayendera bwino ndi zigawo zake, ndikuwonetsetsa kuti zinthu zili bwino.
Kuyeza kwa Microscopic:Kuwunika kagawo ka PCB kumaphatikizapo kudula bolodi lozungulira m'zigawo zopyapyala kuti ziwonedwe ndi kusanthula, kuti muwone zovuta zomwe zingachitike ndi zolakwika.
Kuyang'anira kagawo nthawi zambiri kumachitika koyambirira kopanga ma board board kuti awonetsetse kuti apezeka komanso kukonza zinthu munthawi yake pakupanga ndi kupanga.Njirayi imatha kuyang'ana kuwotcherera, kulumikizana kwa ma interlayer, kulondola kwamagetsi, ndi zina.Poyesa mayeso a biopsy, maikulosikopu kapena maikulosikopu yosanthula ma elekitironi nthawi zambiri amagwiritsidwa ntchito kuyang'ana ndikusanthula magawowo.
Kuyesa kwamagetsi kwa PCB:Kuyesa kwamagetsi kwa PCB kungathandize kutsimikizira ngati magawo amagetsi ndi magwiridwe antchito a gulu lozungulira akukwaniritsa zomwe akuyembekezera, komanso kuzindikira zolakwika ndi zovuta zomwe zingatheke.
Kuyesa kwamagetsi kwa PCB nthawi zambiri kumaphatikizapo kuyesa kulumikizidwa, kuyesa kukana, kuyesa mphamvu, kuyesa kwa impedance, kuyesa kukhulupirika kwa ma sign, komanso kuyesa kugwiritsa ntchito mphamvu.
Kuyesa kwamagetsi kwa PCB kumatha kugwiritsa ntchito zida ndi njira zosiyanasiyana zoyesera, monga zoyeserera, ma multimeter a digito, ma oscilloscopes, ma spectrum analyzers, ndi zina zambiri. Zotsatira za mayeso zidzalembedwa mu lipoti la mayeso kuti awunike ndikusintha gulu ladera.
Kuyesa kwa AOI:Mayeso a AOI (Automated Optical Inspection) ndi njira yodziwira zokha matabwa osindikizidwa pogwiritsa ntchito njira zowonera.Itha kugwiritsidwa ntchito kuti muzindikire zolakwika ndi zovuta pakupanga ma board osindikizidwa, kupewa zolakwika pakupanga zinthu, ndikuwongolera matabwa osindikizidwa.Ubwino wodalirika, kuchepetsa ziwopsezo zolephera, komanso kuwongolera magwiridwe antchito komanso zokolola.
Poyesa AOI, zida zodziwikiratu monga makamera okwera kwambiri, magetsi, ndi mapulogalamu okonza zithunzi amagwiritsidwa ntchito kusanthula ndi kujambula zithunzi za PCB yopangidwa, kenako zithunzi zojambulidwa zimafaniziridwa ndi template yokhazikitsidwa kale.Inde, kuti muzindikire zolakwika ndi zovuta zomwe zingatheke, kuphatikiza zolumikizira za solder, zigawo, mabwalo amfupi ndi mabwalo otseguka, kulondola, zolakwika zapamtunda, ndi zina zambiri.
ICT:Mu Circuit Test imagwiritsidwa ntchito kuyesa zida zamagetsi ndi magwiridwe antchito olumikizirana pagulu.Kuyesa kwa ICT kumatha kuchitidwa pazigawo zosiyanasiyana za kupanga kwa PCB, monga pambuyo popanga PCB, isanayambe kapena itatha kuyika gawo, kuti azindikire ndikuwongolera zovuta pagulu ladera ndikuthana nazo munthawi yake.
Kuyesa kwa ICT kumagwiritsa ntchito zida zapadera zoyesera ndi mapulogalamu kuti ayese zida zamagetsi ndi zolumikizira pa PCB.Zida zoyezera zimalumikizana ndi mayeso pa bolodi la dera kudzera pama probes ndi ma clamps kuti azindikire mawonekedwe amagetsi azinthu zamagetsi pagulu ladera, monga resistors, capacitors, inductors, transistors, ndi zina zambiri. onetsetsani kuti maulumikizidwe ake amagetsi akugwira ntchito momwe anapangidwira.
Mayeso a Singano Yowuluka:Mayeso a Flying Needle amagwiritsa ntchito makina ofufuza okha kuyesa kulumikizidwa kwa dera ndi ntchito pa PCB.Njira yoyeserayi sikutanthauza zoyeserera zokwera mtengo komanso nthawi yopangira, koma m'malo mwake amagwiritsa ntchito ma probes osunthika kuti alumikizane ndi PCB pamwamba kuyesa kulumikizidwa kwa dera ndi magawo ena.
Kuyesa kwa singano zowuluka ndi njira yoyesera yosalumikizana yomwe imatha kuyesa dera lililonse la board, kuphatikiza ma board ang'onoang'ono ndi wandiweyani.Ubwino wa njira yoyeserayi ndi mtengo wotsika woyesera, nthawi yochepa yoyesera, kumasuka kwa kusintha kosinthika kamangidwe ka dera, komanso kuyesa zitsanzo mwachangu.
Kuyesa kogwira ntchito:Kuyesa kwa dera logwira ntchito ndi njira yoyeserera pa PCB kuti muwone ngati kapangidwe kake kakukwaniritsa zofunikira ndi zofunikira.Ndi njira yoyesera yokwanira yomwe ingagwiritsidwe ntchito kuwunika momwe ma PCB amagwirira ntchito, mtundu wazizindikiro, kulumikizana kwa dera, ndi ntchito zina za PCB.
Kuyesa madera ogwirira ntchito nthawi zambiri kumachitika pambuyo poti waya wa PCB wamalizidwa, pogwiritsa ntchito zida zoyeserera ndi mapulogalamu oyeserera kuti ayesere momwe PCB imagwirira ntchito ndikuyesa kuyankha kwake m'njira zosiyanasiyana.Pulogalamu yoyesera imatha kukhazikitsidwa kudzera pamapulogalamu apakompyuta, omwe amatha kuyesa ntchito zosiyanasiyana za PCB, kuphatikiza zolowetsa / zotulutsa, nthawi, mphamvu zamagetsi, zamakono ndi zina.Panthawi imodzimodziyo, tsamba ili likhoza kuzindikira zambiri zomwe zingatheke ndi ma PCB, monga maulendo afupikitsa, mabwalo otseguka, maulumikizidwe olakwika, ndi zina zotero, ndipo amatha kuzindikira mwamsanga ndikukonza nkhanizi kuti zitsimikizire kugwira ntchito ndi kudalirika kwa PCBs.
Kuyesa dera logwira ntchito ndi njira yoyesera yokhazikika yomwe imafuna kupanga mapulogalamu ndi kuyesa kamangidwe ka PCB iliyonse.Choncho, mtengo wake ndi wokwera kwambiri, koma ukhoza kupereka zotsatira zowonjezereka, zolondola, komanso zodalirika.
