Mvura isina mvura PCB yeMagetsi munzvimbo dzakanyorova

MaPCB asingapindi mvura anoita basa guru mukudzivirira michina yemagetsi kubva kuunyoro nezvimwe zvinhu zvakatipoteredza. Kuvhara kunodzivirira kunoshandiswa pamaPCB aya kunoshanda sechidziviriro, kudzivirira mvura, guruva, uye zvinhu zvinosvibisa kubva mukukuvadza michina yemagetsi inokuvadza. Iyi tekinoroji inoshandiswa mumabasa akasiyana-siyana, anosanganisira ekurapa, ehondo, endege, emagetsi evatengi, uye maindasitiri, uko kushanda kwakavimbika munzvimbo dzine hunyoro kwakakosha. Mugwaro iri rakazara, tichaongorora kukosha kwemaPCB asingapindi mvura, kuti akasiyana sei nemaPCB echinyakare, uye nzira dzakasiyana dzekuadzivirira.

Kukosha kweMvura PCBs

Mvura isina mvura PCB inoita basa rakakosha mukusimudzira kuvimbika uye kusimba kwemidziyo yemagetsi mukati mekushandisa kwakasiyana. Nekudzivirira zvinobudirira unyoro uye zvinwiwa kubva pakupinda mukati medunhu, maPCB asingapinde mvura anodzivirira zvinhu zvemagetsi kubva mukuora uye mapfupi maseketi, izvo zvinonyanya kukosha munzvimbo dzine mwando senge midziyo yekunze, marine application, uye midziyo yemukicheni. Iyi yakawedzera dziviriro haingonatsiridza kugadzikana kwekushanda kwemidziyo asiwo zvakanyanya kuwedzera hupenyu hwavo nekudzikisa kuwanda kwekugadzirisa uye kutsiva nekuda kwekutadza kunoenderana nehunyoro.

Uyezve, maPCB asingapindi mvura akakosha mumhando dzakasiyana dzemaindasitiri. Muchikamu chemotokari, vanochengetedza zvinhu zvemagetsi kubva pakufumurwa kwemvura panguva yekunaya, madhaka, uye kugezwa kwemotokari. Mumagetsi evatengi, akadai semafoni, smartwatches, uye mahedhifoni eBluetooth, maPCB asina mvura anodzivirira kukuvadzwa kubva mukuteuka netsaona uye kunyura. Munzvimbo yezvokurapa, maPCB asina mvura anovimbisa kuti michina inogona kucheneswa zvakachengeteka uye kucheneswa pasina kuisa njodzi mukati. Pakazere, kushandiswa kwemaPCB asina mvura kwakakosha pakuona kuvimbika, hupenyu hurefu, uye kuchengetedzeka kwemidziyo yemagetsi munzvimbo dzakasiyana uye dzinoda.

Misiyano kubva kuConventional PCBs

Musiyano mukuru pakati pePCB dzisingapindi mvura uye maPCB akajairwa ari mujasi rekudzivirira rinoiswa pabhodhi. MaPCB asingapindi mvura akaputirwa neresin-based material inoumba chipingamupinyi chisingapinde mvura, nepo maPCB akajairwa achishaya ichi chekudzivirira. Uku kupfekedza hakungodziviriri zvikamu kubva kunyoro asiwo kunopa kuramba kuguruva, makemikari, uye zvimwe zvinosvibisa, zvichiwedzera kuwedzera kuvimbika kwePCB.

Nzira dzekudzivirira Mvura PCBs

Pane nzira dzinoverengeka dzekudzivirira mvura PCBs, imwe neimwe inokodzera mhando dzakasiyana dzemashandisirwo uye mazinga ekudzivirira mvura anodiwa. Dzimwe dzenzira dzakajairika dzinosanganisira:

1. Kushandiswa kweMvura-Inodzivirira PCB Substrates: Kusarudza inodzivirira hunyoro substrate, senge FR-4, FR-1, PTEF, kana Ceramic, inogona kubatsira kusapinda mvura kwePCB kubva mukati, kudzivirira kunwa kwemwando uye kuzvimba.
2. Kushandiswa Kwemvura Isingapindi PaNzvimbo Yepamusoro-Yakawanda: Kuisa chidimbu chakatetepa chepamusoro-density zvinhu zvisingapindi mvura, zvakadai separylene N kana parylene C, pachikamu chekunze chePCB chinogona kupa imwe nhanho yekudzivirira mvura.
3. Kuisa chisimbiso maConnectors: Kuisa chisimbiso chekubatanidza nechinhu chisingapindi mvura kunogona kudzivirira mvura kuti isapararire muPCB kuburikidza nemakonisheni.
4. Kuisa Pendi Isingapindi Mvura paPCB: Kuisa pendi isingapindi mvura paPCB inogona kupa imwe nhanho yekudzivirira mvura, kuve nechokwadi chekuchengetedzwa kwebhodhi kubva pakunyorova.

Ndeipi Maitiro Ekushandisa ari Nani?

Kana zvasvika kumaPCB ekudzivirira mvura, sarudzo yekushandiswa inoenderana nezvinodiwa zvekushandisa uye huwandu hwekudzivirira mvura hunodiwa. Pakati penzira dzakasiyana-siyana dziripo, kupfapfaidza nemaoko kunowanzo shandiswa nekuda kwekururama kwayo kwakanyanya uye kupenya kwayo pamusoro kwakapfava.

Kupfapfaidza nemaoko kunosanganisira kushandisa pfuti yekupfapfaidza kana midziyo yakafanana kuisa chidimbu chakatetepa, chakafanana chechinhu chinodzivirira mvura paPCB. Iyi nzira inobvumira kutonga kwakanyatso pamusoro pekuita kwekushandisa, kuve nechokwadi chekuti nzvimbo dzese dzePCB dzakanyatsoputirwa nezvinhu zvekudzivirira mvura. Pamusoro pezvo, chipfapfaidzo chemaoko chinopa kufukidzwa kuri nani zvichienzaniswa nedzimwe nzira, kuve nechokwadi chekuti PCB yese inodzivirirwa kubva mukunyoro uye zvimwe zvakatipoteredza.

Nekudaro, zvakakosha kuti uzive kuti kusarudzwa kwemaitiro ekunyorera kunofanirwa kuve kwakavakirwa pakunyatso ongororo yezvinodikanwa zvechikumbiro. Kune mamwe maapplication, dzimwe nzira dzakadai sekupa kana kudhibha dzinogona kunge dzakanyanya kukodzera zvichienderana nezvinhu zvakaita semutengo, kuoma, uye nhanho inodiwa yekudzivirira mvura.

Nepo pfapfaidzo yemanyorero ichiwanzo kufarirwa nekuda kwekurongeka kwayo uye kuvharika, iyo yakanakisa dhizaini maitiro ekuvharisa mvura PCBs pakupedzisira zvinoenderana neakasarudzika zvinodiwa zvega rega.

Dzimwe Nzira dzekudzivirira PCB kubva kuMvura

Mukuwedzera kune nzira dzataurwa pamusoro apa, dzimwe nzira mbiri dzakajairika dzekudzivirira PCB kubva mumvura dzinosanganisira:

Kuputira Mvura Kusingapindi Mvura: Izvi zvinosanganisira kupfapfaidza zvinhu zvakaita se epoxy, urethane, kana silicon paPCB kuti isapinde mvura. Zvisinei, nzira iyi ingasakodzera nzvimbo dzine hunyoro hwakawanda uye dzinoparadza nekuda kwekusanamira kwayo kwakaderera uye kukanganiswa nekukuvara.

Zvivharo Zvinodzivirira Mvura: Kushandisa zvivharo zvisingapindi mvura zvakagadzirwa nepurasitiki, silicon, simbi, kana simbi isina ngura kufukidza PCB kunogona kupa dziviriro yakawedzerwa kubva mumvura nehunyoro.

mhedziso

MaPCB asingapindi mvura akakosha pakuona kuti zvishandiso zvemagetsi zvinoshanda zvakanaka munzvimbo dzine hunyoro. Nekunzwisisa kukosha kwekudzivirira mvura, mutsauko kubva kumaPCB akajairwa, uye nzira dzakasiyana-siyana dzekudzivirira mvura, mainjiniya nevagadziri vanogona kusarudza nzira yakakodzera zvinoenderana nezvinodiwa zvavo. Ingave kushandisa substrates dzisingapindi mvura, kuisa zvinhu zvisingapindi mvura, kuvhara zvinobatanidza, kana kushandisa nzvimbo dzisingapindi mvura, kuve nechokwadi chekuti maPCB haapindi mvura kwakakosha kuti zvishandiso zvemagetsi zvirambe zvakavimbika kwenguva refu.
