Kodi Awiri Sided PCB ndi chiyani
PCB yokhala ndi mbali ziwiri ndi bolodi yofunikira ya PCB yomwe imagwiritsidwa ntchito popanga zamagetsi.
PCB yokhala ndi mbali ziwiri ndi chidule cha bolodi yosindikizidwa yokhala ndi mbali ziwiri. Njira zodutsamo ndi mabowo amizere mu ma PCB awa amatha kulumikizana ndimagetsi kuzinthu zosiyanasiyana zamagetsi.
Komanso, titha kugwiritsa ntchito matabwa oyendera mbali ziwiri pazida zamagetsi zamagetsi. Ma PCB awa ali ndi zofunika kwambiri. Amagwiritsa ntchito zida zapamwamba. Izi zimatsimikizira magwiridwe antchito abwino pamakompyuta. bolodi nthawi zambiri perforated pakati kuti agwirizane ndi iwiri mbali PCB.
Kapangidwe ka ma PCB a mbali ziwiri kumasiyana ndi ma PCB wamba. Iwo ali ndi ndondomeko yowonjezera yamkuwa yamkuwa, yomwe imatembenukira kuzungulira mbali ziwiri. Matumba ake a mesh owonongeka adzakwaniritsa zonse zomwe mukufuna.

Double Layer PCB Production Manufacturing Process
Choyamba, tiyenera kukonza zida ndi zipangizo zopangira matabwa a mbali ziwiri. Zida zoyambira zimaphatikizapo mapepala awiri amkuwa ovala kutentha kwapawiri ndi sandpaper. Timafunikanso lumo, cholembera chamafuta, hydrochloric acid, hydrogen peroxide, choboolera pamanja, ndi chitsulo chosungunulira. Komanso, tingafunike awiri opotoka, tepi pepala, soldering chitsulo, solder, rosin, ndi zina.
Zigawo zakunja ndi zamkati zimaphatikizana kupanga bolodi yapawiri ya PCB. Zotsatirazi zikufotokozera zambiri za njira yopangira gawo lakunja la bolodi loyang'ana mbali ziwiri.
Copper plating ndiye gawo loyamba popanga wosanjikiza wakunja wa board board. Mu sitepe yachiwiri, dera limakhazikika, ndiyeno malata amachotsedwa. Pamapeto pake, kupanga kwa dera lakunja kumachitika.
Nthawi zambiri, ogwira ntchito m'mafakitale amagwiritsa ntchito njira ziwiri: "Braking Optical Inspection CCD Ndi Laser." Njira yoyamba imagwiritsa ntchito zowunikira kuti zitsimikizire ngati dera lalifupi liripo. Njira yachiwiri imagwiritsa ntchito laser AOI. Pambuyo poyang'ana pamwamba pa mkuwa, imapanga mitundu yosiyanasiyana ya fluorescence intensity. Njira yachiwiri ndiyo kuyesa njira yayifupi yosinkhasinkha.
Tabwera Kukuthandizani
Ma PCB onse okhala ndi mbali ziwiri amaphatikiza magawo awiri achitetezo amkuwa mbali iliyonse kuti atetezedwenso. Okonza PCB adapanga masanjidwe a matabwa a PCB a mbali ziwiri kutengera matabwa a PCB a mbali imodzi. Njira yodutsa m'mabowo ndi njira yopangira matabwa apamwamba komanso pansi. Kupatula apo, mizere imatha kutsekana, ndipo titha kuwonjezera mizere yatsopano.
Kuti mumvetse bwino malonda ndi ntchito zathu, khalani omasuka kulumikizana ndi gulu lathu lothandizira makasitomala nthawi iliyonse. Tikuyembekezera kukhazikitsa kulumikizana nanu, kuthetsa zosowa zanu, ndikupanga mipata yabwino yogwirizana pamodzi!
