Mawu akuti PCB ndi chidule cha bolodi losindikizidwa ndipo ndi chimodzi mwa zigawo zofunika kwambiri mumakampani a zamagetsi. Amapezeka pafupifupi muzinthu zonse zamagetsi ndipo amagwiritsidwa ntchito polumikiza magetsi pazigawo zilizonse. PCB imakhala ndi bolodi loteteza kutentha, waya wolumikizira ndi pad pomwe zida zamagetsi zimasonkhanitsidwa ndikusungunuka. Ubwino wake umatsimikiza kudalirika kwa zamagetsi, kotero ndiye makampani oyambira komanso makampani akuluakulu amakampani amagetsi.
PCB ili ndi msika waukulu wogwiritsira ntchito, kuphatikizapo zamagetsi, zamagetsi zamagalimoto, kulumikizana, zamankhwala, zankhondo ndi zina zotero. Pakadali pano, zamagetsi zamagetsi zamagalimoto zikukula mwachangu kwambiri ndipo zimakhala ntchito zazikulu za PCB.
Pakati pa ntchito za PCB mu zamagetsi, FPC ili ndi liwiro lomwe likukula mofulumira kwambiri ndipo yatenga gawo lalikulu pamsika wa PCB. FPC imadziwikanso kuti flexible printed circuit. Ndi bolodi lodalirika komanso losinthasintha losindikizidwa lomwe limagwiritsa ntchito PI kapena polyester film ngati maziko. Lili ndi kulemera kopepuka, kufalikira kwa waya wambiri komanso kusinthasintha kwabwino, komwe kumatha kukwaniritsa bwino njira yanzeru, yopyapyala komanso yopepuka yamagetsi am'manja.
Msika wa PCB womwe ukukula mofulumira umabweretsa msika waukulu wopangidwa kuchokera ku zinthu zina. Chifukwa cha chitukuko cha njira ya laser, kukonza laser pang'onopang'ono kumalowa m'malo mwa njira yachikhalidwe yodulira die ndipo kumakhala gawo lofunika kwambiri mu unyolo wa makampani a PCB. Chifukwa chake, m'malo akuluakulu awa pomwe msika wonse wa laser ukukula pang'onopang'ono, msika wa laser wokhudzana ndi PCB ukupitilira kukula mwachangu.
Kukonza laser mu PCB kumatanthauza kudula laser, kuboola laser ndi kulemba chizindikiro cha laser. Poyerekeza ndi njira yachikhalidwe yodulira die, kudula laser sikukhudzana ndipo sikufuna nkhungu yokwera mtengo ndipo kumatha kukhala kolondola kwambiri popanda burr pamphepete. Izi zimapangitsa njira ya laser kukhala yankho labwino kwambiri lodulira PCB ndi FPC.
Poyamba, kudula kwa laser mu PCB kumagwiritsa ntchito makina odulira laser a CO2. Koma makina odulira laser a CO2 ali ndi malo okhudzidwa kwambiri ndi kutentha komanso ntchito yochepa yodulira, sanagwiritsidwe ntchito kwambiri. Koma pamene njira ya laser ikupitilira kukula, magwero ambiri a laser apangidwa ndipo angagwiritsidwe ntchito m'makampani a PCB.
Pakadali pano, gwero la laser lomwe limagwiritsidwa ntchito kwambiri podula PCB ndi FPC ndi nanosecond solid state UV laser yomwe kutalika kwake ndi 355nm. Ili ndi mphamvu yabwino yoyamwa zinthu komanso malo ochepa omwe amakhudzidwa ndi kutentha, zomwe zimathandiza kuti zinthu ziyende bwino kwambiri.
Pofuna kuchepetsa kuyatsa moto ndikupeza mphamvu zambiri, makampani opanga ma laser akupitiliza kupanga UV laser yamphamvu kwambiri, ma frequency apamwamba komanso pulse width yopapatiza. Kenako ma UV laser a 20W, 25W komanso 30W nanosecond adapangidwa kuti akwaniritse bwino kufunikira komwe kukukulirakulira mumakampani a PCB ndi FPC.Pamene mphamvu ya nanosecond UV laser ikukwera, kutentha kwake kumawonjezeka. Kuti ipitirize kugwira ntchito bwino, imafunika laser chiller yeniyeni. S&A Teyu water cooling chiller CWUP-30 imatha kuziziritsa nanosecond UV laser mpaka 30W ndipo ili ndi kukhazikika kwa ±0.1℃. Kulondola kumeneku kumathandiza kuti water chiller iyi yonyamulika izi izitha kuwongolera kutentha kwa madzi bwino kwambiri kuti UV laser ikhale pamalo oyenera kutentha. Kuti mudziwe zambiri. za chiller iyi, dinani https://www.chillermanual.net/portable-laser-chiller-cwup-30-for-30w-solid-state-ultrafast-laser_p246.html
