Zolakwika za PCB ndi kuwongolera kwapadera, pamene tikuyesetsa kukhala ndi miyezo yapamwamba komanso yovuta kwambiri, ndizofunikira kwambiri kuti tithane ndikuchepetsa zilema zopangidwa ndi PCB yomwe ilipo.

Pa gawo lililonse wopanga, mavuto amatha kuchitika zomwe zimayambitsa vuto m'malire omaliza. Zofooka zambiri zimaphatikizapo kuwotcherera, kuwonongeka kwamakina, kuwonongeka kwa makina, kulondola kolakwika, kuyika zolakwika, zovuta zamkati, zovuta zakutha, komanso mavuto azachuma.

Zofooka izi zimatha kubweretsa mabwalo apakatikati, mabwalo otseguka, okonda zikhalidwe, anachepetsa kudalirika, ndikuchepetsa kulephera kwa PCB.

Kapangidwe ka chilema ndikupanga varialicality ndi zifukwa zazikulu ziwiri za zilema za PCB.

Nazi zina mwazomwe zimayambitsa zilema zopangidwa ndi PCB:

Kupanga kwa 1.Impropror

Zolakwika zambiri za PCB zimachokera ku mavuto. Zifukwa zofananira-zofananira zimaphatikizapo kutalika kosakwanira pakati pa mizere, ma buluu ang'onoang'ono kuzungulira zochulukitsa zomwe zimaposa luso lopanga, ndikulekerera mizere yopyapyala kapena mipata yomwe singathe kupezeka ndi ntchito yopanga.

Zitsanzo zina zimaphatikizapo machesi omwe amayambitsa misampha ya asidi, zinthu zabwino zomwe zitha kuwonongeka ndi zotupa zamagetsi, ndi zovuta zotentha.

Kuchita bwino popenda (DFM) ndi malangizo otsatira a PCB kungalepheretse zofooka zambiri.

Kukhudzana ndi Akatswiri opanga kupanga mu njira yopanga kumathandizira kupanga zopanga zopanga zosewerera. Zida zofanizira komanso zida zachilengedwe zitha kutsimikiziranso kulolerana ku zovuta zenizeni padziko lapansi ndikuzindikira kuti pali mavuto. Kupanga kapangidwe kopanga kopanga ndi gawo loyamba pakuchepetsa zilema zomwe zingapangitse kupanga zilema zopangidwa ndi PCB.

2.PCC kuipitsidwa

Kupanga PCB kumafuna kugwiritsa ntchito mankhwala ambiri komanso njira zomwe zingayambitse kuipitsidwa. Panthawi yopanga, ma PCB amadetsedwa mosavuta ndi zida monga zotsalira za flux, mafuta a chala, ma acid yankho, tinthu zinyalala ndi zoyeretsa zodzola.

Zovuta zimayambitsa ziwopsezo zazitali zamagetsi, mabwalo otseguka, mavuto osokoneza, komanso mavuto ochulukirapo. Chepetsani chiopsezo cha kuipitsidwa mwa kusunga malo opangira masitedwe choyera kwambiri, ndikulungamitsa mphamvu zowongolera, komanso kupewa kukhudzana ndi anthu. Kuphunzitsa antchito pamayendedwe oyenera ndikofunikira.

3.Marmarial

Zipangizo zomwe zimagwiritsidwa ntchito popanga PCB ziyenera kukhala zopanda chilema chopanda tsankho. Zida zopanda pcb (monga mawonekedwe apamwamba otsika, predgs, zojambula, ndi zigawo zina) zimatha kukhala ndi zofooka monga mawonekedwe osakwanira, zotupa za galasi, mafinya.

Zolakwika zakuthupi izi zimatha kuphatikizidwa mu pepala lomaliza ndikukhudza magwiridwe antchito. Kuonetsetsa kuti zinthu zonse zatsimikizidwa chifukwa chogulitsa zodziwika bwino zomwe zimawongolera kwambiri zimatha kupewetsa nkhani zokhudzana ndi zinthu. Kuyendera zinthu zomwe zikubwera zimalimbikitsidwanso.

Kuphatikiza apo, kuwonongeka kwamakina, zolakwa za anthu ndi kusintha kwa anthu zitha kukhudzanso kupanga kwa PCB.

Zofooka zimachitika mu PCB pakupanga ndi kupanga ndi kupanga. Kuzindikira zofooka zomwe zimadziwika bwino kwambiri za PCB kumathandizira kuyang'ana kwambiri popewa kupewa komanso kuyeserera. Mfundo zofunika kwambiri zosumira zimawunikira, kuwongolera moyenera njira, ogwiritsira ntchito amaphunzirira, kuyang'ana bwino, matebulo ndi mfundo zolakwitsa ndi zolakwitsa.
