Kodi matabwa osinthasintha amakhala ndi moyo wotani?

Chiyambi:

Mu positi iyi yabulogu, tiyang'ana mozama za moyo wa PCB wosinthika, zinthu zake, ndi njira zowonetsetsa kuti zikuyenda bwino m'moyo wake wonse.

Ma Flex PCB, omwe amadziwikanso kuti ma board osinthika osindikizira, atchuka m'mafakitale osiyanasiyana chifukwa cha kusinthasintha kwawo komanso kuthekera kopirira kupindika ndi kupindika.Mabwalowa amagwiritsidwa ntchito kwambiri pazida zamagetsi monga mafoni a m'manja, ukadaulo wovala, zida zamankhwala, ndi zida zamagalimoto.Komabe, ngakhale kuchulukirachulukira kwa ma PCB osinthika, anthu ambiri sakudziwabe za alumali moyo wa PCBs osinthika komanso momwe amakhudzira kudalirika kwazinthu.

Nthawi ya alumali ya PCB yosinthika ndi nthawi yomwe dera limasunga magetsi ndi makina ake

katundu akasungidwa bwino.Zimakhudzidwa ndi zinthu zosiyanasiyana, kuphatikizapo kupanga zinthu, kupanga

njira, zosungirako, zinthu zachilengedwe, kusonkhana ndi nthawi yosonkhanitsa.

Chimodzi mwazinthu zazikulu zomwe zimakhudza moyo wa alumali wa ma PCB osinthika ndikusankha zinthu.Ma PCB osinthika amapangidwa kuchokera ku filimu ya polyimide kapena poliyesitala ndipo amapereka kusinthasintha komanso kulimba.Zidazi zimapereka kukana kwabwino kwa kutentha, chinyezi, ndi mankhwala, zomwe zimapangitsa kuti mabwalo azigwira ntchito m'malo ovuta.Komabe, pakapita nthawi, zinthuzi zimatha kuwononga kapena kuyamwa chinyezi, zomwe zimapangitsa kuwonongeka kwa magwiridwe antchito kapena kulephera kuzungulira.Chifukwa chake, ndikofunikira kusankha zida zapamwamba kwambiri zamatchulidwe oyenera kuti zitsimikizire moyo wautali.

Kapangidwe kake kamagwiranso ntchito yofunika kwambiri pozindikira moyo wa alumali wa ma PCB osinthika.Kusamalira moyenera, kusungirako ndi kusonkhanitsa njira ziyenera kutsatiridwa pofuna kupewa kuipitsidwa, kuyamwa kwa chinyezi kapena kuwonongeka panthawi yopanga.Kupatuka kulikonse kuchokera ku malangizo opangira opangira kusokoneza kudalirika kwa dera ndikufupikitsa moyo wake wa alumali.Opanga ayenera kutsatira mfundo makampani ndi kukhalabe okhwima kulamulira khalidwe kuonetsetsa moyo wautali wa PCBs kusintha.

Zinthu zosungira zimakhudza kwambiri alumali moyo wa ma PCB osinthika.Zozungulira izi ziyenera kusungidwa pamalo otetezedwa opanda chinyezi chambiri, kusinthasintha kwa kutentha, ndi kuwala kwa dzuwa.Chinyezi chimatha kudutsa m'mphepete ndi m'mphepete mwa njira, kuchititsa delamination kapena dzimbiri zamayendedwe oyendetsa.Kutentha kwambiri kumathandizira kukalamba ndikuchepetsa zinthu zakuthupi.Choncho, tikulimbikitsidwa kusunga ma PCB osinthika m'matumba osindikizidwa a polyethylene okhala ndi mapaketi a desiccant kapena muzitsulo zotsekedwa ndi vacuum kuti muchepetse kuyamwa kwa chinyezi.

Zinthu zachilengedwe monga kugwedezeka, kupindika ndi kukhudzana ndi mankhwala zingakhudzenso moyo wa alumali wa ma PCB osinthika.Mabwalo osinthika amapangidwa kuti athe kupirira kupindika kapena kupindika mobwerezabwereza, koma kupsinjika kwamakina kopitilira muyeso kungayambitse ming'alu kapena kusweka kwa njira kapena kutsekereza.Kuphatikiza apo, kukhudzana ndi mankhwala owononga kapena mpweya kumatha kuwononga zida zozungulira ndikuwononga magwiridwe antchito.Chifukwa chake, zomwe zikuyembekezeredwa zogwirira ntchito ziyenera kuganiziridwa ndipo njira zodzitetezera, monga zokutira zofananira kapena zotsekera, ziyenera kutengedwa kuti zithandizire kulimba kwa dera ndikuwonjezera nthawi ya alumali.

Kuti muwonetsetse kuti ma PCB osinthika akugwira ntchito bwino pashelufu yawo yonse, kuwunika pafupipafupi ndi kuyezetsa ndikofunikira.Kuyang'ana pafupipafupi kumatha kuzindikira zizindikiro zilizonse zakuwonongeka, monga kusinthika kwamtundu, delamination, kapena kusintha kwamagetsi.Kuphatikiza apo, kuyezetsa magwiridwe antchito kumatha kuwunika momwe dera likugwirira ntchito motengera momwe amagwirira ntchito, kulola kuti mavuto omwe angakhalepo kuti adziwike ndikuwongoleredwa asanalephereke.Kuchita mayesowa pakapita nthawi kumathandizira kukulitsa moyo wa alumali wa PCB yosinthika ndikupewa zolephera zosayembekezereka.

Kukulitsa moyo wa alumali wa ma PCB osinthika, msonkhano wa PCB umagwira ntchito yofunika kwambiri.Kusonkhana kwa PCB kumatanthauza njira yoyika zida zamagetsi pa PCB.Njira zogwirira ntchito zoyenerera zimatsimikizira kuti zigawozo zimagwirizanitsidwa bwino ndi PCB komanso kuti ma solder ndi odalirika.

Zikafika pakukulitsa moyo wa alumali wa ma PCB, nthawi ya msonkhano mutatha kulongedza ndi chinthu chofunikira kwambiri.PCB iyenera kusonkhanitsidwa mkati mwa nthawi yoyenera mutatha kulongedza.Kusungidwa kwa nthawi yayitali kwa ma PCB opakidwa kungayambitse kuwonongeka kwa zinthu ndi zigawo zake, zomwe zimakhudza moyo wa alumali.

Kufunika kwa PCB alumali moyo:

PCB alumali moyo ndi zofunika pa zifukwa zingapo.Choyamba, kugwiritsa ntchito ma PCB omwe adadutsa nthawi yawo ya alumali kumatha kuyambitsa zovuta kapena kulephera.Zida zamagetsi monga conductivity ndi impedance zingakhudzidwe, zomwe zimayambitsa kulephera kwa dera.Zida zamakina, monga kusinthasintha kapena kuuma, zimawonongekanso pakapita nthawi.

Chachiwiri, kasamalidwe zipangizo ndi zigawo zikuluzikulu PCB alumali moyo n'kofunika kwambiri mtengo.Posamalira bwino alumali moyo, opanga angathe kupewa zinyalala ndi zosafunika ndalama kugwirizana ndi ntchito PCBs ntchito.Izi ndizofunikira makamaka kwa mafakitale omwe ali ndi zofunikira zapamwamba za PCB, chifukwa mafakitalewa amakhala ndi ma PCB ambiri.

Kuti muwonjezere moyo wosungira wa ma PCB osinthika, njira zina zodzitetezera ziyenera kutengedwa.

Choyamba, ma PCB ayenera kusungidwa m'malo olamulidwa ndi kutentha koyenera ndi chinyezi.Kutentha kwambiri ndi chinyezi kumatha kufulumizitsa kuwonongeka kwa zinthu ndi zigawo zake.

Chachiwiri, kuyika bwino ndikofunikira kuti muteteze PCB panthawi yosungira.Ayenera kudzazidwa m'mapaketi oteteza chinyezi komanso anti-static kuti ateteze kuwonongeka kapena kuipitsidwa.Kuphatikiza apo, kuyika chizindikiro molondola kwa masiku opanga ndi masiku otha ntchito ndikofunikira kuti kasamalidwe koyenera ka zinthu.

Zinthu zingapo zimatha kukhudza alumali moyo wa PCBs.

Kuwonekera ku chinyezi, chinyezi ndi mpweya wowononga kungayambitse kuwonongeka kwakukulu.Kutentha kwapamwamba kungathe kutsindika zipangizo ndi kukhudza katundu wawo.Chifukwa chake, ndikofunikira kusamalira ndikusunga ma PCB mosamala kuti muchepetse zinthu izi.

Kugwiritsa ntchito ma PCB otha ntchito kumatha kubweretsa zoopsa komanso zoopsa.Kulumikizana kwadera kosadalirika kungayambitse zida zamagetsi, zomwe zimakhudza chitetezo ndi magwiridwe antchito.M'mapulogalamu ovuta kwambiri monga zida zamankhwala kapena makina amagalimoto, zotsatira zogwiritsa ntchito ma PCB otha ntchito zimatha kukhala zovuta.

Powombetsa mkota

Kutalika kwa moyo wa PCB wosinthika kumakhudzidwa ndi zinthu zambiri, kuphatikiza kapangidwe kazinthu, kupanga, kusungirako, zinthu zachilengedwe komanso kusonkhana.Posankha zida zabwino, kutsatira njira zopangira zopangira, kusunga mabwalo pamalo olamulidwa ndikuganizira zomwe zikuyembekezeka, mutha kuwonjezera moyo wa alumali wa ma PCB osinthika ndikuwonetsetsa kuti magwiridwe antchito odalirika a nthawi yayitali.Kuyang'anira ndi kuyezetsa pafupipafupi kumathandizanso kuti pakhale kukhulupirika kwadera ndikuzindikira zovuta zilizonse.Kumvetsetsa alumali moyo wa ma PCB osinthika ndikofunikira kwa opanga, opanga ndi ogwiritsa ntchito kumapeto kuti akwaniritse kudalirika kwazinthu komanso moyo wautali.
Alumali moyo wa PCBs kusintha n'kofunika kuganizira opanga ndi owerenga.Kumvetsetsa zinthu zomwe zimakhudza moyo wa alumali ndikugwiritsa ntchito kusungirako moyenera ndi machitidwe agulu kungathandize kuwonjezera moyo wa PCB yanu.Poyang'anira bwino zipangizo ndi zigawo, opanga amatha kuonetsetsa kuti ntchito yabwino, yotsika mtengo komanso yotetezeka.Onetsetsani kuti mufunsane ndi wopanga kapena wogulitsa kuti mudziwe zambiri za moyo wa alumali wa PCB wosinthika.
