Inteko yihariye ya PCB na PCBA

Ibisobanuro

Ibyerekeye Igishushanyo mbonera cya PCB

Mugihe dushushanya ikibaho cya PCB, natwe dufite amategeko agenga: ubanza, tondekanya imyanya yibyingenzi ukurikije inzira yerekana ibimenyetso, hanyuma ukurikire "umuzenguruko ubanza bigoye hanyuma byoroshye, ibice bigize ibice kuva binini kugeza bito, ibimenyetso bikomeye kandi intege nke zo gutandukanya, hejuru na hasi.Gutandukanya ibimenyetso, gutandukanya ibimenyetso na sisitemu ya digitale, gerageza gukora insinga ngufi zishoboka, kandi utume imiterere ishoboka ”;hagomba kwitabwaho bidasanzwe gutandukanya “ibimenyetso byubutaka” n '“imbaraga zubutaka”;ibi ahanini ni ukurinda ingufu zubutaka Umurongo rimwe na rimwe ufite umuyoboro munini unyuramo.Niba iyi miyoboro yinjijwe mubimenyetso byerekana ibimenyetso, bizagaragarira kumurongo usohoka binyuze muri chip, bityo bigira ingaruka kumikorere ya voltage imikorere yumuriro w'amashanyarazi.
Noneho, umwanya uteganya hamwe nicyerekezo cyicyerekezo cyibigize bigomba kuba bihuye nibishoboka hamwe nogukoresha igishushanyo cyumuzunguruko, bizoroha cyane kubungabunga no kugenzura nyuma.
Umugozi wubutaka ugomba kuba mugufi kandi mugari bishoboka, kandi insinga zacapwe zinyura mumirongo isimburana nazo zigomba kwagurwa bishoboka.Mubisanzwe, dufite ihame mugihe insinga, insinga yubutaka niyo yagutse, insinga z'amashanyarazi nizakabiri, naho insinga ya signal niyo ngufi.
Mugabanye ibitekerezo bisubirwamo, ibyinjijwe nibisohoka byo gukosora akayunguruzo kahantu hashoboka, iyi ntego nukugabanya urusaku rwurusaku rwamashanyarazi.

Igisubizo kimwe

Ibikoresho byindimu nka thermistors bigomba kubikwa kure hashoboka bituruka kumasoko yubushyuhe cyangwa ibikoresho byumuzunguruko bitera kwivanga.
Intera iringaniye hagati yimirongo ibiri kumurongo igomba kuba irenze 2mm, kandi intera iri hagati ya chip ristoriste na chip capacitor igomba kuba irenga 0.7mm.
Iyinjiza Iyungurura ubushobozi igomba gushyirwa hafi ishoboka kumurongo ugomba gushungura.
Mu gishushanyo mbonera cya PCB, ibibazo bikunze kugaragara ni amabwiriza yumutekano, EMC no kwivanga.Kugirango dukemure ibyo bibazo, dukwiye kwitondera ibintu bitatu mugihe dushushanya: intera yumwanya, intera yikurikiranya nintera yinjira.Ingaruka.
Kurugero: Intera ya creepage: iyo voltage yinjiza ari 50V-250V, LN imbere ya fuse ni .52.5mm, mugihe voltage yinjira ari 250V-500V, LN imbere ya fuse ni .05.0mm;gukuraho amashanyarazi: iyo voltage yinjira ari 50V-250V, L - N ≥ 1,7mm imbere ya fuse, iyo voltage yinjira ari 250V-500V, L - N ≥ 3.0mm imbere ya fuse;nta gisabwa gisabwa nyuma ya fuse, ariko gerageza kugumana intera runaka kugirango wirinde kwangirika kwumuzunguruko mugufi kumashanyarazi;uruhande rwibanze AC kugeza DC igice ≥ 2.0 mm;uruhande rwibanze DC hasi hasi ≥4.0mm, nkuruhande rwibanze hasi;uruhande rwibanze kuruhande rwa kabiri ≥6.4mm, nka optocoupler, Y capacitor nibindi bice bigize ibice, umwanya wa pin uri munsi cyangwa uhwanye na 6.4mm kugirango ushire;transformateur ibyiciro bibiri ≥6.4mm cyangwa irenga, ≥8mm yo gukingirwa.

Kwerekana Uruganda

Ibibazo

Q1: Nigute ushobora kwemeza neza ubwiza bwa PCBs?
A1: PCB zacu zose ni ikizamini 100% harimo Ikizamini cya Flying Probe, E-test cyangwa AOI.

Q2: Igihe cyo kuyobora ni ikihe?
A2: Icyitegererezo gikenera iminsi 2-4 y'akazi, umusaruro rusange ukenera iminsi 7-10 y'akazi.Biterwa na dosiye nubunini.

Q3: Nshobora kubona igiciro cyiza?
A3: Yego.Gufasha abakiriya kugenzura ibiciro nibyo duhora tugerageza gukora.Ba injeniyeri bacu bazatanga igishushanyo cyiza cyo kubika ibikoresho bya PCB.
