Isikali semakethi yokusetyenzwa kwelaser sibonakala sikhula ngokucothayo kule minyaka mibini idlulileyo. Nangona kunjalo, kukho imakethi enye yelaser esakhula ngesantya esikhawulezayo-i-PCB ehambelana nemarike yelaser. Ke injani imakethi yePCB yangoku? Kutheni le nto inokuzisa uphuhliso olukhulu kushishino lwelaser?
Ishishini lePCB kunye neFPC elinophuhliso olukhawulezayo kunye nemfuno enkulu yemarike
I-PCB imfutshane kwibhodi yesekethe eprintiweyo kwaye yenye yezona ndawo zibalulekileyo kushishino lwe-elektroniki. Ikhona phantse kuyo yonke imveliso yombane kwaye isetyenziselwa uqhagamshelo lombane kwinxalenye nganye. I-PCB iqulethe i-baseboard ekhuselayo, ucingo oludibanisayo kunye nephedi apho izinto ze-elektroniki zidityanisiwe kwaye zixutywe. Umgangatho wayo ugqiba ukuthembeka kwe-electronics, ngoko ke imboniselo yesiseko kunye necandelo elikhulu lecandelo loshishino lombane.
I-PCB inemakethi yesicelo esibanzi, kubandakanywa i-electronics yabathengi, i-elektroniki yemoto, unxibelelwano, unyango, umkhosi njalo njalo. Okwangoku, i-elektroniki yabathengi kunye ne-automobile electronics zikhula ngokukhawuleza kwaye zibe zezona zicelo ziphambili zePCB.
Phakathi kwesicelo se-PCB kwizinto zombane zabathengi, i-FPC inesona santya sikhula ngokukhawuleza kwaye yathatha isabelo esikhulu kunye nesikhulu kwimakethi yePCB. I-FPC ikwabizwa ngokuba yi-flexible printed circuit. Yibhodi yesekethe ethembekileyo kakhulu kwaye eguquguqukayo esebenzisa iPI okanye ifilimu yepolyester njengesiseko sezinto. Ibonisa ubunzima obulula, ukuxinana okuphezulu kokusasazwa kweengcingo kunye nokuguquguquka okuhle, okunokuthi kuhlangane ngokugqibeleleyo nobukrelekrele, umncinci kwaye ulula umkhwa kwi-elektroniki ephathwayo.
Imakethi yePCB ekhula ngokukhawuleza ikhokelela kwimarike enkulu ephuma kuyo. Ngokuphuhliswa kobuchule belaser, ukusetyenzwa kwelaser ngokuthe ngcembe kuthathe indawo yobuchule bokusika bemveli kwaye bube yinxalenye ebalulekileyo kushishino lwePCB. Ke ngoko, kule ndawo inkulu apho yonke imarike yelaser inophuhliso olucothayo, imarike yelaser enxulumene nePCB isakhula ngokukhawuleza.
I-advanteji ye-laser processing kwi-PCB kunye ne-FPC
Ukusetyenzwa kweLaser kwiPCB kubhekisa ekusikeni kwelaser, ukugrumba ngelaser kunye nokumakishwa kwelaser. Xa kuthelekiswa neendlela zokusika zemveli, ukusika kwe-laser akunxibelelwano kwaye akwenzi’t ifuna ukungunda okuxabisa kakhulu kwaye inokufezekisa ukuchaneka okuphezulu ngaphandle kwe-burr kumphetho osikiweyo. Oku kwenza ubuchule belaser isisombululo esifanelekileyo sokusika iPCB kunye neFPC.
Ekuqaleni, ukusika i-laser kwi-PCB kwamkela umatshini wokusika we-CO2 we-laser. Kodwa umatshini wokusika we-CO2 we-laser unommandla omkhulu ochaphazelekayo wokushisa kunye nokusebenza kakuhle kokusika, awuzange ube nesicelo esibanzi. Kodwa njengoko ubuchule belaser buqhubeka bukhula, ngakumbi nangakumbi imithombo yelaser iyaqanjwa kwaye inokusetyenziswa kushishino lwePCB.
Okwangoku, umthombo we-laser osetyenziswa ngokuqhelekileyo kwi-PCB kunye ne-FPC yokusika yi-nanosecond eqinile ye-laser ye-UV egama layo liyi-355nm. Inezinga elingcono lokufunxa imathiriyeli kunye nendawo encinci echaphazelekayo yobushushu, eyenza ukuba kuphunyezwe ukuchaneka okuphezulu kokusebenza.
Ukunciphisa ukutshaja kunye nokufezekisa ukusebenza kakuhle okuphezulu, amashishini e-laser ayaqhubeka nokuphuhlisa i-laser ye-UV yamandla aphezulu, i-frequency ephezulu kunye nobubanzi obuncinci be-pulse. Ke kamva i-20W, 25W kunye ne-30W nanosecond UV lasers zayilwa ukuhlangabezana ngcono nemfuno ekhulayo kwishishini le-PCB kunye ne-FPC.
Njengoko amandla e-nanosecond UV laser eba phezulu, kokukhona ubushushu buya kuvelisa. Ukugcina ukusebenza kakuhle kokusetyenzwa, kufuna i-laser chiller echanekileyo. S&A I-Teyu yokupholisa amanzi kwi-chiller CWUP-30 iyakwazi ukupholisa i-nanosecond UV laser ukuya kuthi ga kwi-30W kunye neempawu±0.1℃ uzinzo. Oku kuchanekileyo kwenza le chiller yamanzi ephathekayo ilawule ubushushu bamanzi kakuhle ukuze i-laser ye-UV ihlale ikuluhlu olufanelekileyo lobushushu. Ukuze ufumane inkcazelo engakumbi. malunga nale chiller, cofa https://www.chillermanual.net/portable-laser-chiller-cwup-30-for-30w-solid-state-ultrafast-laser_p246.html
