Ibhodi eliphelele le-PCB lidinga ukubhekana nezinqubo eziningi kusuka ku-Design to Design Product. Lapho zonke izinqubo zisendaweni, ekugcineni kuzongena kusixhumanisi sokuhlola. Amabhodi we-PCB kuphela ahlolwe azosetshenziswa kumkhiqizo, ukuze usebenze kanjani umsebenzi wokuhlola wesekethe wePCB, lesi yisihloko esikhathazekile ngawo wonke umuntu. Umhleli olandelayo wesifunda saseJinhong uzokutshela ngolwazi olufanele lokuhlolwa kwebhodi lesekethe!
1. Lapho ulinganisa i-voltage noma uhlole i-waveform nge-oscilloscope probe, ungabangeli umjikelezo omfushane phakathi kwezikhonkwane ezihlanganisiwe ngenxa yokubuyisa ukuholelwa kokuhola noma ukushefa, kanye nokulinganisa kumjikelezo ophrintiwe oxhumekile oxhumene ngqo ne-PIN. Noma yimuphi umjikelezo omfushane wesikhashana ungalimaza kalula umjikelezo ohlanganisiwe. Kufanele uqaphele kakhulu lapho uhlola amasekethe ahlanganisiwe we-CMOs ahlanganisiwe.
2. Akuvunyelwe ukusebenzisa i-iron ye-soldering yokuthengisa ngamandla. Qiniseka ukuthi i-iron ye-soldering ayikhokhiswa. Phansi igobolondo lensimbi elungiselelwe. Qikelela umjikelezo we-MOS. Kuphephile ukusebenzisa i-iron yesijikelezo esingu-6-8v
3. Uma udinga ukwengeza izingxenye zangaphandle ukuze ungene esikhundleni sengxenye eyonakele yomjikelezo ohlanganisiwe, izingxenye ezincane kufanele zisetshenziswe, futhi i-wiring kufanele ibe nengqondo ukugwema ukuhlanganiswa okuhlangene kwe-amplifitor kanye ne-preamplifier complifier kufanele kusingathwe kahle. Ukuphela komhlaba.
I-4. Kuyenqatshelwe ngokuphelele ekuhlolweni ngokuqondile i-TV, umsindo, ividiyo neminye imishini ngaphandle kwama-transformation we-log isoladi ngensimbi nemishini enamagobolondo aphansi. Yize i-General Radio Cassette Recorder ine-transformer yamandla, lapho uhlangana ne-TV ekhethekile noma imishini yomsindo, ikakhulukazi i-chassis yomshini isetshenzisiwe, kufanele uthole ukuthi i-chassis yomshini isetshenzisiwe, kufanele ithole umjikelezo ophansi wokuhlinzekwa kwamandla, okubangela ukunwetshwa kwephutha.
5 Uma izimo ezingenhla zihlangatshezwa, ukuhlaziya nokuhlola kuzoba lula kakhulu.
6. Ungahluleli ukuthi umjikelezo ohlanganisiwe ulimele kalula. Ngoba ama-circuits ahlanganiswe kakhulu ahlanganiswa ngokuqondile, uma umjikelezo uma engajwayelekile, kungadala ukuthi izinguquko eziningi zikagesi, futhi lezi zinguquko azibangelwa ukulimala komjikelezo ohlanganisiwe. Ngaphezu kwalokho, kwezinye izimo, i-voltage elinganisiwe yephini ngalinye ihlukile kokujwayelekile lapho amanani afana noma asondelene komunye nomunye, akusho ukuthi umjikelezo ohlanganisiwe ulungile. Ngoba amanye amaphutha athambile ngeke adale ushintsho ku-DC Voltage.
