Moni, mafani aukadaulo achichepere! Lero, tiphunzira zaukadaulo wosangalatsa womwe umadziwika kuti photosensitive PCB. Kodi munayamba mwadzifunsapo momwe zida zanu zamagetsi zomwe mumakonda, monga mafoni am'manja ndi mapiritsi, zimapangidwira? Kupanga kwawo kumagwiritsa ntchito photosensitive (photoresist) PCB. Tiyeni tiyambe ndi kuphunzira zambiri za luso lodabwitsali!
Photosensitized PCBs ndi mtundu wa bolodi kusindikizidwa dera lomwe lili ndi wosanjikiza amene tcheru kuwala. Ukadaulo uwu umathandizira makampani kupanga zida zamagetsi zofewa komanso zazing'ono mwachangu. The Semixlab zithunzi pcb wosanjikiza wapadera ndi kuwala tcheru, kuchititsa katundu wake kusintha pamene poyera kuwala. Njirayi, yomwe imadziwika kuti photolithography, ndi momwe timapangira matabwa apamwamba a zipangizo zamagetsi zambiri.
M'masiku akale, ntchito yopanga matabwa ozungulira inali yayitali komanso yovuta. Zinatengera makina apadera ndi luso lakuya kuti wopanga ajambule mawonekedwe ozungulira pama PCB akale. Lero, komabe, kupezeka kwa ma PCB owonetsa zithunzi kwapangitsa kupanga ma boardboard kukhala kosavuta. Ndipo kotero opanga mapulogalamu amatha kupanga mapangidwe ovuta ndipo amagwiritsa ntchito kuwala kuti apange mapangidwe pa PCBs zithunzi. Semixlab iyi zithunzi pcb imafulumizitsa ndondomekoyi ndikupangitsa kuti ikhale yolondola.
Ma PCB a Photosensitive pazamagetsi ali ndi maubwino angapo. Chimodzi ndi chakuti amathandizira kupanga mapangidwe atsatanetsatane atsatanetsatane. Chachiwiri, zimapulumutsa nthawi ndipo siziwononga ndalama zambiri popanga. Pali zolakwika zochepa - zomwe zimapanga zinthu zabwino - chifukwa mapangidwe amasamutsidwa pogwiritsa ntchito kuwala. Pazonse, The Semixlab filimu ya pcb photoresist photosensitive imathandizira kwambiri kudalirika kwa mapangidwe amagetsi ndi kupanga.
Tsopano, kuti mwadziwitsidwa za zinthu zabwino kwambiri za Semixlab pcb photosensitive youma filimu angachite, chikulepheretsani inu kupanga dera bolodi wanu? Nayi njira yosavuta yothandizira:
Mosakayikira, luso lamakono la PCB limakupatsani mwayi wambiri wopanga ndi kupanga zamagetsi. The Semixlab zida za semiconductor amatha kupanga matabwa ozungulira omwe mumawakonda kwambiri kapenanso magawo azinthu zamalonda. Okonza akhoza kukhala opanga ndikupita nawo kumalo atsopano. Choncho, nthawi ina mukadzaponya ma elekitironi, ganizirani za ma PCB aja amene anathandiza kuti zonse zitheke!
