Isilinganiso semakethe yokucubungula i-laser sibonakala sikhula kancane eminyakeni emibili edlule. Nokho, kunemakethe ye-laser eyodwa esathuthuka ngesivinini esisheshayo -- PCB processing laser market ehlobene. Ngakho injani imakethe ye-PCB yamanje? Kungani ingaletha intuthuko enkulu embonini ye-laser?
Imboni ye-PCB ne-FPC ethuthuka ngokushesha kanye nesidingo esikhulu semakethe
I-PCB imfushane ngebhodi lesifunda eliphrintiwe futhi ingenye yezingxenye ezibaluleke kakhulu embonini ye-electronics. Itholakala cishe kuyo yonke imikhiqizo ye-elekthronikhi futhi isetshenziselwa ukuxhuma ugesi ezingxenyeni ngayinye. I-PCB iqukethe ibhodi le-insulating, intambo yokuxhuma kanye nephedi lapho izingxenye ze-elekthronikhi zihlanganiswa futhi zishiselwa khona. Ikhwalithi yayo inquma ukwethembeka kwezinto zikagesi, ngakho-ke iyimboni eyisisekelo kanye nengxenye enkulu yomkhakha wemboni yezogesi.
I-PCB inemakethe yezicelo ebanzi, okuhlanganisa izinto zikagesi zabathengi, izinto zikagesi zezimoto, ezokuxhumana, ezokwelashwa, ezempi nokunye. Okwamanje, ama-electronics abathengi kanye ne-automobile electronics kukhula ngokushesha okukhulu futhi kuba izinhlelo zokusebenza ezinkulu ze-PCB.
Phakathi kwesicelo se-PCB kuma-electronics abathengi, i-FPC inesivinini esikhula ngokushesha futhi yathatha isabelo semakethe esikhulu nesikhudlwana semakethe ye-PCB. I-FPC yaziwa nangokuthi isekethe ephrintiwe eguquguqukayo. Kuyibhodi lesifunda eliphrintiwe elithembeke kakhulu neliguquguqukayo elisebenzisa ifilimu ye-PI noma i-polyester njengento eyisisekelo. Ifaka isisindo esilula, ukuminyana okuphezulu kokusatshalaliswa kwezintambo nokuguquguquka okuhle, okungahlangabezana ngokuphelele nokuthambekela okukhaliphile, okuncanyana nokukhanya ku-elekthronikhi ephathwayo.
Imakethe ye-PCB ekhula ngokushesha iholela emakethe enkulu ephuma kokunye. Ngokuthuthuka kwendlela ye-laser, ukucutshungulwa kwe-laser kancane kancane kungena esikhundleni senqubo yendabuko yokusika futhi kuba yingxenye ebalulekile kuchungechunge lwemboni ye-PCB. Ngakho-ke, kule ndawo enkulu lapho yonke imakethe ye-laser inokuthuthuka kancane, imakethe ye-laser ehlobene ne-PCB isathuthuka ngokushesha
Inzuzo yokucubungula i-laser ku-PCB naku-FPC
Ukucutshungulwa kwe-laser ku-PCB kubhekise ekusikeni nge-laser, ukubhola nge-laser nokumaka nge-laser. Uma kuqhathaniswa nendlela yokusika yendabuko, ukusika nge-laser akuthinteki futhi ’ akudingi isikhunta esibizayo futhi kungafinyelela ukunemba okuphezulu ngaphandle kwe-burr onqenqemeni olusikiwe. Lokhu kwenza inqubo ye-laser ibe yisixazululo esifanelekile sokusika i-PCB ne-FPC
Ekuqaleni, ukusika i-laser ku-PCB kusebenzisa umshini wokusika we-CO2 laser. Kodwa umshini wokusika we-CO2 we-laser unendawo enkulu ethintekile ekushiseni kanye nokusebenza kahle okuphansi kokusika, awuzange ube nokusetshenziswa okubanzi. Kodwa njengoba indlela ye-laser iqhubeka nokuthuthuka, imithombo eminingi ye-laser iyasungulwa futhi ingasetshenziswa embonini ye-PCB
Okwamanje, umthombo we-laser ovame ukusetshenziswa osetshenziswa ekusikeni kwe-PCB ne-FPC i-nanosecond solid state UV laser obude bayo obungama-355nm. Inezinga lokumunca elingcono kanye nendawo encane ethintekile ukushisa, okuvumela ukuzuza ukunemba okuphezulu kokucubungula
Ukuze kuncishiswe ukushaja futhi kuzuzwe ukusebenza kahle okuphezulu, amabhizinisi e-laser ayaqhubeka nokuthuthukisa i-UV laser yamandla aphezulu, imvamisa ephezulu kanye nobubanzi be-pulse obuncane. Ngakho kamuva i-20W, 25W kanye nama-lasecond UV lasers angu-30W asungulwa ukuze ahlangabezane kangcono nesidingo esikhulayo embonini ye-PCB ne-FPC.
Njengoba amandla e-nanosecond UV laser eba phezulu, lapho izokhiqiza ukushisa okwengeziwe. Ukugcina ukusebenza kahle kokucubungula, kudinga i-laser chiller enembile. S&I-Teyu water cooling chiller CWUP-30 iyakwazi ukupholisa i-nanosecond UV laser kufika ku-30W kanye nezici ±0.1℃ ukuzinza. Lokhu kunemba kwenza lesi sishicileli samanzi esiphathwayo silawule izinga lokushisa lamanzi kahle kakhulu ukuze i-laser ye-UV ihlale ikubanga lokushisa elifanele. Ukuze uthole olunye ulwazi. mayelana nale chiller, chofoza https://www.chillermanual.net/portable-laser-chiller-cwup-30-for-30w-solid-state-ultrafast-laser_p246.html
