Kukula kwa msika wa laser processing kukuwoneka kuti kukukula pang'onopang'ono m'zaka ziwiri zapitazi. Komabe, pali msika umodzi wa laser womwe ukukulabe mwachangu - msika wa PCB wokhudzana ndi laser. Ndiye msika waposachedwa wa PCB uli bwanji? Chifukwa chiyani zingabweretse chitukuko chachikulu chamakampani a laser?
Makampani a PCB ndi FPC omwe ali ndi chitukuko chofulumira komanso kufunikira kwakukulu kwa msika
PCB ndi yochepa kwa bolodi yosindikizidwa ndipo ndi imodzi mwazinthu zofunika kwambiri pamakampani opanga zamagetsi. Imapezeka pafupifupi pamtundu uliwonse wamagetsi ndipo imagwiritsidwa ntchito polumikizira magetsi pagawo lililonse. PCB imakhala ndi insulating baseboard, waya wolumikizira ndi pedi pomwe zida zamagetsi zimasonkhanitsidwa ndikuwotcherera. Ubwino wake umasankha kudalirika kwa zamagetsi, ndiye maziko ake ndi gawo lalikulu kwambiri lamakampani opanga zamagetsi.
PCB ali lonse ntchito msika, kuphatikizapo ogula zamagetsi, galimoto zamagetsi, kulankhulana, zachipatala, asilikali ndi zina zotero. Pakadali pano, zida zamagetsi zamagetsi ndi zamagetsi zamagalimoto zikukula mwachangu kwambiri ndipo zimakhala zofunikira kwambiri pa PCB.
Pakati pa mapulogalamu a PCB pamagetsi ogula, FPC ili ndi liwiro lomwe likukula kwambiri ndipo imatenga gawo lalikulu pamsika wa PCB. FPC imadziwikanso kuti flexible print circuit. Ndi bolodi yodalirika komanso yosinthika yosindikiza yomwe imagwiritsa ntchito PI kapena filimu ya poliyesitala ngati maziko. Imakhala ndi kulemera kopepuka, kachulukidwe kakang'ono ka kugawa kwa waya komanso kusinthasintha kwabwino, komwe kumatha kukumana mwanzeru, zoonda komanso zopepuka pamagetsi am'manja.
Msika wa PCB womwe ukukula mwachangu umabweretsa msika waukulu wotuluka. Ndi chitukuko cha njira laser, laser processing pang'onopang'ono m'malo miyambo kufa kudula njira ndi kukhala mbali yofunika kwambiri mu unyolo PCB makampani. Chifukwa chake, m'malo akulu awa pomwe msika wonse wa laser umakhala wocheperako, msika wokhudzana ndi PCB wa laser ukukulabe mwachangu.
Ubwino wa laser processing mu PCB ndi FPC
Laser processing mu PCB amatanthauza kudula laser, kubowola laser ndi chizindikiro laser. Poyerekeza ndi njira yachikhalidwe yodulira kufa, kudula kwa laser sikukhudzana ndipo sikumatero’t imafuna nkhungu yokwera mtengo ndipo imatha kuchita bwino kwambiri popanda burr pamphepete. Izi zimapangitsa laser njira njira yabwino kudula PCB ndi FPC.
Poyambirira, laser kudula mu PCB utenga CO2 laser kudula makina. Koma makina odulira a laser a CO2 ali ndi kutentha kwakukulu komwe kumakhudzidwa komanso kutsika kwachangu, kunalibe ntchito yayikulu. Koma pamene njira ya laser ikupitilira kukula, magwero ochulukirapo a laser amapangidwa ndipo angagwiritsidwe ntchito pamakampani a PCB.
Pakadali pano, gwero la laser lomwe limagwiritsidwa ntchito kwambiri mu PCB ndi FPC kudula ndi nanosecond solid state UV laser yomwe kutalika kwake ndi 355nm. Ili ndi mayamwidwe abwinoko azinthu komanso madera ang'onoang'ono omwe amakhudzidwa ndi kutentha, zomwe zimathandiza kuti zitheke kuwongolera bwino kwambiri.
Kuti muchepetse kuwotcha ndikuchita bwino kwambiri, mabizinesi a laser akupitiliza kupanga laser ya UV yamphamvu kwambiri, ma frequency apamwamba komanso kugunda kwapang'onopang'ono. Chifukwa chake pambuyo pake 20W, 25W komanso ngakhale 30W nanosecond UV lasers adapangidwa kuti akwaniritse zomwe zikuchulukirachulukira mumakampani a PCB ndi FPC.
Pamene mphamvu ya nanosecond UV laser ikukwera, kutentha kwambiri kumapangika. Kukhalabe mulingo woyenera kwambiri processing ntchito, pamafunika yeniyeni laser chiller. S&A Teyu madzi ozizira chiller CWUP-30 amatha kuziziritsa nanosecond UV laser mpaka 30W ndi mbali±0.1℃ bata. Kulondola kumeneku kumathandizira kuti chiller yam'madzi ichi chizitha kuwongolera kutentha kwamadzi bwino kwambiri kuti laser ya UV nthawi zonse ikhale pamalo abwino kutentha. Kuti mudziwe zambiri. za kuzizira kumeneku, dinani https://www.chillermanual.net/portable-laser-chiller-cwup-30-for-30w-solid-state-ultrafast-laser_p246.html
