Gulu lathunthu la PCB liyenera kudutsa njira zambiri kuchokera pamapangidwe mpaka kumaliza. Njira zonse zikakhazikitsidwa, pamapeto pake zidzalowa mu ulalo woyendera. matabwa okha anayesedwa PCB adzagwiritsidwa ntchito mankhwala, kotero mmene kuchita PCB dera ntchito yoyendera gulu , Iyi ndi mutu kuti aliyense nkhawa kwambiri. Mkonzi wotsatira wa Jinhong Circuit akuwuzani za chidziwitso choyenera cha kuyesa kwa board board!
1. Poyezera voteji kapena kuyesa mawonekedwe a waveform ndi kafukufuku wa oscilloscope, musapangitse kagawo kakang'ono pakati pa zikhomo za dera lophatikizika chifukwa cha kutsetsereka kwa chiwongolero choyeserera kapena kafukufuku, ndikuyesa pagawo losindikizidwa lolumikizidwa mwachindunji ndi pini. Kuzungulira kwakanthawi kochepa kumatha kuwononga mosavuta gawo lophatikizika. Muyenera kusamala kwambiri poyesa mabwalo ophatikizika a CMOS okhala ndi phukusi.
2. Sichiloledwa kugwiritsa ntchito chitsulo chosungunula kuti chiwotchedwe ndi mphamvu. Onetsetsani kuti chitsulo cha soldering sichinaperekedwe. Gwirani chipolopolo cha chitsulo chosungunuka. Samalani ndi dera la MOS. Ndizotetezeka kugwiritsa ntchito chitsulo chocheperako cha 6-8V.
3. Ngati mukufuna kuwonjezera zigawo zakunja kuti zilowe m'malo mwa gawo lowonongeka la dera lophatikizika, zigawo zing'onozing'ono ziyenera kugwiritsidwa ntchito, ndipo waya ayenera kukhala wololera kuti apewe kugwirizanitsa kosafunika kwa parasitic, makamaka mphamvu ya audio amplifier Integrated circuit ndi preamplifier circuit iyenera kukhala. kugwiridwa bwino. The ground terminal.
4. Ndizoletsedwa kuyesa mwachindunji TV, zomvera, kanema ndi zida zina popanda chosinthira mphamvu chodzipatula chokhala ndi zida ndi zida zokhala ndi zipolopolo zokhazikika. Ngakhale chojambulira chojambulira chawayilesi chimakhala ndi chosinthira mphamvu, mukakumana ndi zida zapadera za TV kapena zomvera, makamaka mphamvu yotulutsa kapena mtundu wamagetsi omwe amagwiritsidwa ntchito, muyenera kudziwa kaye ngati galimotoyo imayimbidwa. , mwinamwake ndizosavuta kwambiri TV, zomvetsera ndi zipangizo zina zomwe zimayimbidwa ndi mbale yapansi zimapangitsa kuti pakhale kagawo kakang'ono ka magetsi, komwe kumakhudza dera lophatikizika, zomwe zimapangitsa kuti cholakwikacho chiwonjezeke.
5. Musanayambe kuyang'ana ndi kukonzanso dera lophatikizidwa, choyamba muyenera kudziwa bwino ntchito ya dera lophatikizika lomwe limagwiritsidwa ntchito, dera lamkati, magawo akuluakulu amagetsi, ntchito ya pini iliyonse, ndi mphamvu yachibadwa ya pini, waveform ndi mfundo yogwira ntchito ya dera lopangidwa ndi zigawo zozungulira. Ngati zomwe zili pamwambazi zakwaniritsidwa, kusanthula ndi kuyang'ana kudzakhala kosavuta.
6. Musaweruze kuti dera lophatikizika limawonongeka mosavuta. Chifukwa mabwalo ambiri ophatikizika amalumikizidwa mwachindunji, dera likakhala lachilendo, lingayambitse kusintha kwamagetsi kangapo, ndipo zosinthazi sizimayamba chifukwa cha kuwonongeka kwa dera lophatikizika. Kuphatikiza apo, nthawi zina, voteji yoyezera ya pini iliyonse imakhala yosiyana ndi yanthawi zonse Zikafanana kapena zikuyandikirana, sizitanthauza kuti dera lophatikizika ndilabwino. Chifukwa zolakwika zina zofewa sizingayambitse kusintha kwa magetsi a DC.
