Ungakhetha kanjani indawo efanelekile ye-PCB ukuze uthole impilo ende yesevisi?
Izinto zokwakha zesekethe zithembele kumakhondakta wekhwalithi ephezulu nezinto zokwakha ze-dielectric ukuxhuma izingxenye zesimanje eziyinkimbinkimbi ukuze zisebenze kahle. Kodwa-ke, njengamakhondaktha, lawa makhondaktha ekhopha e-PCB, noma amabhodi e-DC noma ama-mm Wave PCB, adinga ukuvikelwa kokulwa nokuguga kanye ne-oxidation. Lesi sivikelo c...Funda kabanzi -
Isingeniso sokuhlolwa kokwethembeka kwamabhodi esekethe e-PCB
Ibhodi lesifunda le-PCB lingahlanganisa izingxenye eziningi ze-elekthronikhi ndawonye, ezingonga isikhala kahle kakhulu futhi ngeke zivimbele ukusebenza kwesekethe. Kunezinqubo eziningi ekwakhiweni kwebhodi lesifunda le-PCB. Okokuqala, sidinga ukusetha Hlola imingcele yebhodi lesifunda le-PCB. Okwesibili, thina ...Funda kabanzi -
Yimaphi amaphuzu okufanele anakwe ekwakhiweni kwe-DC-DC PCB?
Uma kuqhathaniswa ne-LDO, umjikelezo we-DC-DC uyinkimbinkimbi kakhulu futhi unomsindo, futhi izidingo zesakhiwo nesakhiwo ziphezulu. Izinga lesakhiwo lithinta ngqo ukusebenza kwe-DC-DC, ngakho-ke kubaluleke kakhulu ukuqonda ukwakheka kwe-DC-DC 1. Isakhiwo esibi ●EMI, DC-DC SW pin izoba ne-d...Funda kabanzi -
Ukuthuthukiswa Kwethrendi ye-Rigid-Flexible PCB Manufacturing Technology
Ngenxa yezinhlobo ezahlukene zama-substrates, inqubo yokukhiqiza ye-PCB eguquguqukayo eqinile ihlukile. Izinqubo eziyinhloko ezinquma ukusebenza kwayo ubuchwepheshe bezintambo ezincane kanye nobuchwepheshe be-microporous. Ngezidingo ze-miniaturization, multi-function kanye nomhlangano ophakathi nendawo we-electronic pr...Funda kabanzi -
Umehluko we-PTH NPTH ku-PCB ngokusebenzisa izimbobo
Kungabhekwa ukuthi kunezimbobo eziningi ezinkulu nezincane ebhodini lesifunda, futhi kungatholakala ukuthi kunezimbobo eziningi eziminyene, futhi imbobo ngayinye yenzelwe injongo yayo. Lezi zimbobo zingahlukaniswa ngokuyisisekelo zibe yi-PTH (Plating Through Hole) kanye ne-NPTH (Non Plating Through Hole) ezicwebezelayo...Funda kabanzi -
PCB Silkscreen
Ukuphrinta kwesikrini se-PCB sikasilika kuyinqubo ebalulekile ekukhiqizeni amabhodi wesifunda se-PCB, okunquma ikhwalithi yebhodi le-PCB eliphelile. Ukwakhiwa kwebhodi lesifunda se-PCB kuyinkimbinkimbi kakhulu. Kunemininingwane eminingi emincane enqubweni yokuklama. Uma ingaphathwa ngendlela efanele, izoba nomthelela ku...Funda kabanzi -

Ungabhekana kanjani nomugqa wokuhlukanisa isignali ye-PCB?
Enqubweni yokuklama kwe-PCB, ukuhlukaniswa kwendiza yamandla noma ukuhlukaniswa kwendiza ephansi kuzoholela endizeni engaphelele. Ngale ndlela, lapho isignali ihanjiswa, indiza yayo eyinkomba izosuka kwelinye indiza yamandla iye kwenye indiza yamandla. Lesi simo sibizwa ngokuthi ukuhlukaniswa kwe-signal span. ...Funda kabanzi -
Ingxoxo ngenqubo yokugcwalisa imbobo ye-PCB ye-electroplating
Usayizi wemikhiqizo ye-elekthronikhi uya uba mncane futhi ube mncane, futhi ukunqwabelanisa ngokuqondile nge-vias eyimpumputhe kuyindlela yokuklama yokuxhumanisa okuphezulu. Ukwenza umsebenzi omuhle wokupakisha izimbobo, okokuqala, ukugcwala phansi komgodi kufanele kwenziwe kahle. Kukhona abakhiqizi abaningi...Funda kabanzi -
