Kutheni le nto iPCB (ibhodi yesekethe eprintiweyo) kufuneka iqatywe ngepeyinti esemthethweni?Indlela yokupeyinta ngokukhawuleza nangokuchanekileyo ibhodi yesiphaluka?

I-PCB ibhekisa kwibhodi yesekethe eprintiweyo (ibhodi yesekethe eprintiweyo), engumboneleli woqhagamshelo lombane lwamacandelo e-elektroniki.Kuxhaphake kakhulu kwishishini le-elektroniki, kwaye ezintathu ezichasene ne-adhesive (ipeyinti) zisetyenziswa kakhulu kuyo, kwaye akukho hlobo lokuncamathelisa olunje nge-PCB yobungqina obuthathu (ipeyinti).Ngapha koko, umaleko wokuncamathelisa ubungqina obuthathu (peyinti) uqatywe kwiPCB.ipeyinti).

Ukusebenzisa iipeyinti ezintathu ezichasayo kukuthintela i-PCB ukuba yonakaliswe yimiba yangaphandle kunye nokuphucula ubomi benkonzo ye-PCB.Njengoko iimveliso zombane ezikumgangatho ophezulu zineemfuno eziphezulu neziphezulu kumgangatho we-PCB, iingubo ezihambelanayo zisetyenziswa ngokubanzi kwiibhodi zesekethe.

I-anti-peyinti emithathu, umatshini wokugquma

Izinto ezenza lula umonakalo wePCB:

Ukufuma yeyona nto ixhaphakileyo kwaye eyona nto iyonakalisayo kwiiPCBs.Ukufuma okugqithisileyo kuya kunciphisa kakhulu ukunyanzeliswa kwe-insulation phakathi kwabaqhubi, ukukhawulezisa ukubola, ukunciphisa ixabiso le-Q, kunye ne-corrode conductors.Ngokuqhelekileyo kwenzeka ukuba inxalenye yensimbi ye-PCB ine-patina, ebangelwa ukuphendulwa kweekhemikhali zobhedu lwensimbi kunye nomphunga wamanzi kunye ne-oksijini.

Kanye njengokuba yingozi enkulu ngamakhulu ezinto ezingcolisayo onokuzifumana naphi na kwibhodi yesekethe eprintiweyo, kwaye zinokubangela iziphumo ezifanayo njengohlaselo lokufuma, njengokungasebenzi kwe-elektroniki, ukubola kwee-conductor, kunye neesekethe ezimfutshane.Ungcoliseko oluhlala lufumaneka kwiinkqubo zombane lunokuba yimichiza eshiyekileyo kwinkqubo yokwenziwa.Ezi zinto zingcolisa ziquka i-fluxes, i-solvent release agents, amaqhekeza esinyithi, kunye neenki zokumakisha.

Kukwakho amaqela amakhulu ongcoliseko olubangelwa zizandla zabantu, njenge-oyile yomzimba, iminwe, izithambiso kunye neentsalela zokutya.Zininzi izinto ezingcolisa umoya kwindawo yokusebenza, ezifana nesitshizi setyuwa, isanti, amafutha, iasidi, omnye umphunga omdaka kunye nokungunda.

Kutheni usebenzisa izinto ezintathu zokungancamathelisi (ipeyinti)?

I-PCB eqatywe nge-anti-ancamathelisi ezintathu (ipeyinti) ayipheleli nje ekuqinisekiseni ukufuma, uthuli-ubungqina, kwaye ingangeni manzi, kodwa ikwanokuxhathisa ukothuka kwengqele nobushushu, ukuxhathisa ukwaluphala, ukuxhathisa kwimitha, ukumelana nokutshiza kwetyuwa, ukuxhathisa umhlwa kwe-ozone, ukungcangcazela. ukuchasana, ukuguquguquka okulungileyo kunye nokubambelela okuqinileyo.Xa ichaphazeleka yimiba emibi yendawo yokusebenza, inokunciphisa okanye isuse ukuthotywa kokusebenza kwe-elektroniki.

Ngenxa yeemeko ezahlukeneyo zokusetyenziswa kweemveliso ezahlukeneyo zokuphela, iimfuno zokusebenza ze-adhesive conformal ziya kugxininiswa.Izixhobo zasekhaya ezinjengeefriji, oomatshini bokuhlamba, kunye nezifudumezi zamanzi zineemfuno eziphezulu zokumelana nokufuma, ngelixa iifeni zangaphandle kunye nezibane zesitrato zifuna iimveliso ezinomsebenzi obalaseleyo wokulwa nenkungu.

Indlela yokufaka ngokukhawuleza nangokufanelekileyo i-adhesive ehambelanayo (ipeyinti) kwi-PCB?

Kwishishini lokulungisa iPCB, kukho izixhobo ezizenzekelayo zokugquma ipeyinti ekhuselayo kwiibhodi zesekethe- oomatshini abathathu bokuchasa ipeyinti, abakwabizwa ngokuba ngoomatshini abathathu bokuncamathelisa bepeyinti, izitshizi ezintathu zokuthambisa iglu, izitshizi ezintathu ze-anti-peyinti. , oomatshini bokutshiza bepeyinti abathathu bepeyinti, njl.njl., benzelwe ukulawula ulwelo, kwaye bagqume umaleko wepeyinti ehambelanayo kumphezulu wePCB, njengokugquma umaleko wefotoresist kumphezulu wePCB ngokudipha, ukutshiza. okanye spin coating.

Umatshini wesithathu wokunqanda ipeyinti usetyenziselwa ukutshiza ngokuchanekileyo, ukugquma kunye nokuvuza iglue, ipeyinti kunye nolunye ulwelo kwinkqubo yemveliso ukuya kwindawo echanekileyo yemveliso nganye, kwaye ingasetyenziselwa ukufezekisa umzobo womgca, isangqa okanye i-arc.

Oomatshini abathathu bokuthintela ipeyinti sisixhobo sokutshiza esenzelwe ngokukhethekileyo ukutshiza iipeyinti ezichasene nepeyinti ezintathu.Ekubeni izinto eziza kutshizwa kunye nolwelo lokutshiza oluza kusetyenziswa luhluke, ukukhethwa kweengxenye zomatshini wokugquma ngokubhekiselele kwisakhiwo sezixhobo zikwahluke.Umatshini wokugquma i-anti-peyinti emithathu wamkela inkqubo yokulawula ikhompyutha yamva nje, enokuqonda unxibelelwano lwe-axis emithathu, kwaye ixhotyiswe kunye Inkqubo yokulandelela indawo yekhamera inokulawula ngokuchanekileyo indawo yokutshiza.
