Igama elithi PCB lisisishunqulelo sebhodi yesekethe eprintiweyo kwaye lelinye lawona macandelo abalulekileyo kushishino lwe-elektroniki. Likho phantse kuyo yonke imveliso ye-elektroniki kwaye lisetyenziselwa uqhagamshelo lombane kwinxalenye nganye. I-PCB inebhodi yesiseko ekhuselayo, ucingo oludibanisayo kunye nephedi apho izinto ze-elektroniki zihlanganiswa khona kwaye zinyibilika. Umgangatho wayo ugqiba ukuthembeka kwezixhobo ze-elektroniki, ngoko ke lishishini elisisiseko kwaye lelona candelo likhulu kushishino lwezixhobo ze-elektroniki.
I-PCB inemakethi ebanzi yezicelo, kuquka izixhobo ze-elektroniki zabathengi, izixhobo ze-elektroniki zeemoto, unxibelelwano, ezonyango, ezomkhosi njalo njalo. Okwangoku, izixhobo ze-elektroniki zabathengi kunye nezixhobo ze-elektroniki zeemoto ziphuhliswa ngokukhawuleza kwaye ziba zezona zicelo ziphambili ze-PCB.
Phakathi kwesicelo se-PCB kwi-elektroniki yabathengi, i-FPC inesantya esikhula ngokukhawuleza kwaye ithatha isabelo esikhulu semarike kwimarike ye-PCB. I-FPC ikwaziwa njengesekethe eprintiweyo eguquguqukayo. Yibhodi yesekethe eprintiweyo ethembekileyo kakhulu neguquguqukayo esebenzisa ifilimu ye-PI okanye ye-polyester njengesixhobo sesiseko. Inobunzima obulula, ubuninzi bokusasazwa kweentambo kunye nokuguquguquka okuhle, okunokuhlangabezana ngokugqibeleleyo nomkhwa okrelekrele, obhityileyo nolula kwi-elektroniki yeselula.
Imarike ye-PCB ekhula ngokukhawuleza ikhokelela kwimarike enkulu evela kwezinye izinto. Ngophuhliso lwendlela ye-laser, ukucutshungulwa kwe-laser kuthatha indawo yendlela yendabuko yokusika iidayi kwaye kuba yinxalenye ebalulekileyo kuthotho lweshishini le-PCB. Ke ngoko, kule ndawo inkulu apho yonke imakethi ye-laser inophuhliso olucothayo, imakethi ye-laser enxulumene ne-PCB isakhula ngokukhawuleza.
Ukucubungula nge-laser kwi-PCB kubhekisa ekusikeni nge-laser, ukubhola nge-laser kunye nokumakishwa nge-laser. Xa kuthelekiswa nendlela yendabuko yokusika ngodayi, ukusika nge-laser akuthinteli kwaye akufuni ukungunda okubiza kakhulu kwaye kunokufikelela ngokuchanekileyo okuphezulu ngaphandle kwe-burr kumphetho wokusika. Oku kwenza indlela ye-laser ibe sisisombululo esifanelekileyo sokusika i-PCB kunye ne-FPC.
Ekuqaleni, ukusika nge-laser kwi-PCB kwakusebenzisa umatshini wokusika nge-laser we-CO2. Kodwa umatshini wokusika nge-laser we-CO2 unendawo echaphazeleka kakhulu kubushushu kunye nokusebenza kakuhle kokusika, wawungenalo ukusetyenziswa ngokubanzi. Kodwa njengoko ubuchule be-laser buqhubeka nophuhliso, imithombo emininzi ye-laser iyaveliswa kwaye ingasetyenziswa kushishino lwe-PCB.
Okwangoku, umthombo welaser osetyenziswa kakhulu kwi-PCB nakwi-FPC cutting yi-nanosecond solid state UV laser ene-wavelength eyi-355nm. Inesantya esingcono sokufunxa izinto kunye nendawo encinci echaphazeleka bubushushu, nto leyo evumela ukuba kufezekiswe ukuchaneka okuphezulu kokucubungula.
Ukunciphisa ukutsha kunye nokufezekisa ukusebenza kakuhle okuphezulu, amashishini e-laser ayaqhubeka nokuphuhlisa i-UV laser enamandla aphezulu, i-frequency ephezulu kunye nobubanzi obuncinci be-pulse. Ngoko ke kamva kwaveliswa ii-nanosecond UV lasers ezingama-20W, 25W kunye ne-30W ukuze kuhlangatyezwane ngcono nemfuno ekhulayo kwishishini le-PCB kunye ne-FPC.Njengoko amandla e-nanosecond UV laser esiya esanda, kokukhona iya kuvelisa ubushushu obungakumbi. Ukuze igcine ukusebenza kakuhle kokucubungula, ifuna i-laser chiller echanekileyo. I-S&A Teyu water cooling chiller CWUP-30 iyakwazi ukupholisa i-nanosecond UV laser ukuya kuthi ga kwi-30W kwaye inendawo yozinzo lwe-±0.1℃. Oku kuchaneka kwenza le sixhobo samanzi esiphathwayo silawule ubushushu bamanzi kakuhle ukuze i-UV laser ihlale ikwinqanaba lobushushu elifanelekileyo. Ukuze ufumane ulwazi oluthe kratya. malunga nale sixhobo, cofa https://www.chillermanual.net/portable-laser-chiller-cwup-30-for-30w-solid-state-ultrafast-laser_p246.html
