I-PCB isifinyezo sebhodi lesifunda eliphrintiwe futhi ingenye yezingxenye ezibaluleke kakhulu embonini yama-elekthronikhi. Ikhona cishe kuyo yonke imikhiqizo yama-elekthronikhi futhi isetshenziselwa ukuxhumanisa ngogesi kuzo zonke izingxenye. I-PCB yakhiwe ibhodi lesisekelo elivikela ukushisa, ucingo oluxhumanisayo kanye nephedi lapho izingxenye zama-elekthronikhi zihlanganiswa khona futhi zihlanganiswa. Ikhwalithi yayo inquma ukuthembeka kwama-elekthronikhi, ngakho-ke iyimboni eyisisekelo kanye nemboni enkulu yezingxenye embonini yama-elekthronikhi.
I-PCB inemakethe ebanzi yezicelo, okuhlanganisa ama-electronic abathengi, ama-electronic ezimoto, ukuxhumana, ezokwelapha, ezempi njalo njalo. Okwamanje, ama-electronic abathengi kanye nama-electronic ezimoto athuthuka ngokushesha futhi aba yizicelo ezinkulu ze-PCB.
Phakathi kokusetshenziswa kwe-PCB kuma-electronics abathengi, i-FPC inesivinini esikhula ngokushesha futhi ithathe isabelo semakethe esikhulu nesikhudlwana semakethe ye-PCB. I-FPC yaziwa nangokuthi isekethe ephrintiwe eguquguqukayo. Iyibhodi yesekethe ephrintiwe ethembekile kakhulu futhi eguquguqukayo esebenzisa ifilimu ye-PI noma ye-polyester njengezinto eziyisisekelo. Inesisindo esincane, ukuminyana okuphezulu kokusatshalaliswa kwentambo kanye nokuguquguquka okuhle, okungahlangabezana ngokuphelele nomkhuba ohlakaniphile, omncane nolula kuma-electronics eselula.
Imakethe ye-PCB ekhula ngokushesha iholela emakethe enkulu esuselwe kokunye. Ngokuthuthuka kwendlela ye-laser, ukucutshungulwa kwe-laser kancane kancane kuthatha indawo yendlela yendabuko yokusika ngodayi futhi kuba yingxenye ebalulekile ochungechungeni lwemboni ye-PCB. Ngakho-ke, kule ndawo enkulu lapho yonke imakethe ye-laser inentuthuko ehamba kancane, imakethe ye-laser ehlobene ne-PCB isathuthuka ngokushesha.
Ukucutshungulwa kwe-laser ku-PCB kubhekisela ekusikeni nge-laser, ukubhoboza nge-laser kanye nokumaka nge-laser. Uma kuqhathaniswa nendlela yendabuko yokusika ngodayi, ukusika nge-laser akuthinteki futhi akudingi isikhunta esibizayo futhi kungafinyelela ukunemba okuphezulu ngaphandle kwe-burr emphethweni wokusika. Lokhu kwenza indlela ye-laser ibe yisisombululo esifanele sokusika i-PCB kanye ne-FPC.
Ekuqaleni, ukusika nge-laser ku-PCB kwakusebenzisa umshini wokusika nge-laser we-CO2. Kodwa umshini wokusika nge-laser we-CO2 unendawo enkulu ethintekile ekushiseni kanye nokusebenza kahle okuphansi kokusika, wawungenalo ukusetshenziswa okubanzi. Kodwa njengoba inqubo ye-laser iqhubeka nokukhula, imithombo eminingi ye-laser iyasungulwa futhi ingasetshenziswa embonini ye-PCB.
Okwamanje, umthombo we-laser osetshenziswa kakhulu ekusikeni kwe-PCB kanye ne-FPC yi-nanosecond solid state UV laser enobude obungu-355nm. Inesilinganiso esingcono sokumuncwa kwezinto kanye nendawo encane ethintekile ekushiseni, okwenza kube nokunemba okuphezulu kokucubungula.
Ukuze kuncishiswe ukusha nokufeza ukusebenza kahle okuphezulu, amabhizinisi e-laser ayaqhubeka nokuthuthukisa i-UV laser enamandla aphezulu, imvamisa ephezulu kanye nobubanzi obuncane bokushaya kwenhliziyo. Ngakho-ke kamuva kwasungulwa ama-nanosecond UV lasers angu-20W, 25W ngisho nama-30W ukuze kuhlangatshezwane kangcono nesidingo esikhulayo embonini ye-PCB kanye ne-FPC.Njengoba amandla e-nanosecond UV laser eba phezulu, kulapho izokhiqiza khona ukushisa okwengeziwe. Ukuze igcine ukusebenza kahle kokucubungula, idinga i-laser chiller enembile. I-S&A Teyu water cooling chiller CWUP-30 iyakwazi ukupholisa i-nanosecond UV laser efika ku-30W futhi inezici zokuqina ze-±0.1℃. Lokhu kunemba kwenza le-water chiller ephathekayo ilawule izinga lokushisa kwamanzi kahle ukuze i-UV laser ihlale isebangeni lokushisa elifanele. Ukuze uthole ulwazi olwengeziwe. mayelana nale-chiller, chofoza ku-https://www.chillermanual.net/portable-laser-chiller-cwup-30-for-30w-solid-state-ultrafast-laser_p246.html
