Kodi mwakonzeka kupanga mapulojekiti a 5G/IoT? Werengani nkhaniyi kuti mudziwe zambiri zokhudza kupanga ma PCB a HDI a 5G ndipo mapangidwe ndi kupanga ma PCB a IoT kwasintha kwa zaka zambiri. Kuyambira pa matabwa osavuta okhala ndi mbali imodzi kapena angapo, mpaka ma PCB apamwamba kwambiri a High-Density (HDI). Kupita patsogolo kulikonse kwaukadaulo m'mabwalo osindikizira angagwiritsidwe ntchito m'maukadaulo osiyanasiyana. Chimodzi mwa izi…

Mukapanga pulojekiti ya PCB, chimodzi mwa zinthu zoyamba ndi kufotokozera PCB stackup. Ndi izi, muyenera kudziwa zinthu za PCB zomwe mungagwiritse ntchito. Simudzatha kufotokoza chokhazikika cha dielectric, chomwe ndi chofunikira kwambiri pa mizere yanu yolamulidwa ndi impedance, ngati simunasankhe zinthu za PCB yanu. Kuphatikiza apo, mudzakhala ndi…

Nthawi Yogwiritsira Ntchito Ma PCB Osinthasintha Ndi Olimba: Kugwiritsa Ntchito Kwenikweni Mu Zovala Zovala ndi Zipangizo Zachipatala Kodi mukukonzekera kugwiritsa ntchito Ma PCB Osinthasintha pa mapulojekiti anu? Simungathe kusankha ngati mungagwiritse ntchito osinthasintha kapena olimba pa iwo. Nkhaniyi iyenera kukuthandizani ndi chisankho chanu. Chiyambi Ma PCB amakono osinthasintha adabuka pamene mafilimu a polyimide adapangidwa m'ma 1960….

Mukatha kupanga ndi kubweretsa chitsanzo chabwino, gawo lanu lotsatira lingakhale kukulitsa kupanga zinthu zambiri. Pali kusiyana kwakukulu pakati pa kukonzekera kupanga chitsanzo ndi kukonzekera kupanga zinthu zambiri. Ndikofunika kuti musalemedwe ndi ndondomeko ndi dongosolo. Chabwino n'chakuti UET PCB (https://uetpcb.com/turnkey-pcb-assembly/) ili ndi kiyi yosinthira…

M'dziko lililonse, misonkho ndi mitengo iyenera kudziwika potumiza kapena kutumiza zinthu kunja. Misonkho kapena mitengo imatha kusiyanasiyana kutengera mtundu wa chinthucho. Pankhaniyi, njira ya HS code imagwiritsidwa ntchito kuzindikira bwino chinthu chilichonse. HS Code ya PCBA imagwiritsidwa ntchito makamaka kuzindikira zinthu zokhudzana ndi PCBA. Zogulitsa za PCBA…

Masiku ano, zinthu zamagetsi zakhala gawo lofunika kwambiri pa moyo wathu watsiku ndi tsiku. Mwachitsanzo, kuyambira pa watchi yanu yowonera mpaka laputopu yanu komanso zida zamakina, chilichonse tsopano ndi chamagetsi. Komabe, pakati pa zinthu zamagetsi izi ndi PCBA (Printed Circuit Board Assembly). Koma pankhani yotumiza ndi kutumiza kunja, khodi ya HTS ya…

Nthawi zambiri timafunikira ma multimeter kuti tiyese mphamvu zamagetsi zosiyanasiyana. Timazigwiritsa ntchito tsiku lililonse pa ntchito zambiri zaukadaulo. Multimeter imatithandiza kuwona mphamvu zamagetsi, mphamvu zamagetsi, kukana, komanso kupitiriza kwa magetsi. Kuyambira kukonza nyumba mpaka ntchito zamagetsi zaukadaulo, ma multimeter ndi ofunikira kwambiri. Komabe, mungasokonezeke mukayang'ana koyamba pa dial ndi mabatani. Pamenepo ndi pomwe kumvetsetsa multimeter…

Tonsefe tikudziwa kuti ma air conditioner amathandiza kwambiri kuti nyumba ndi maofesi athu azizizira. Koma kuti ntchito iyende bwino, chinthu chofunikira kwambiri chamagetsi ndi AC capacitor. Mukatsegula chipangizo cha AC ndikuyang'ana pa capacitor, mupeza mawaya amitundu ingapo. Mitundu ya mawaya amenewa imatha kusokoneza oyamba kumene….

GND ndi mawu ofunikira omwe amagwiritsidwa ntchito mu zamagetsi. Ndipotu, mudzawona kuti yalembedwa pafupifupi pazida zonse zamakono zomwe zimagwiritsa ntchito magetsi. Anthu ambiri sadziwa tanthauzo la GND, kotero amafunsa kuti, “Kodi GND ndi chiyani mu zamagetsi?” Kumvetsetsa zoyambira za GND ndikofunikira chifukwa kumamaliza dera lonselo ndikupangitsa zida kugwira ntchito. Popanda…

Dziko la zamagetsi limadalira mphamvu yamagetsi yolunjika (DC). Mphamvu yamagetsi yosinthasintha ndi yoopsa pazida zamagetsi zambiri zomwe zimakhala zovuta kugwiritsa ntchito. Komabe, ngati simugwiritsa ntchito mabatire, mphamvu yamagetsi yosinthasintha imasinthidwa kukhala mphamvu yamagetsi yolunjika. Kenako imakhala yoyenera kugwiritsidwa ntchito mu chipangizocho. Koma si zida zonse zomwe zimagwiritsa ntchito mphamvu yamagetsi yamagetsi yofanana. Chipangizo chilichonse,…
