Uma sikhuluma nje, ama-PCB anezinombolo ezilinganayo anama-PCB anezinombolo ezingavamile, ...
- Idizayini ye-Half-hole yeBhodi Lesekethe
I-metalized half-hole isho ukuthi ngemva kwembobo yokubhoboza (i-drill, i-gong groove), bese kuthi eyesibili ibhobolwe futhi ibunjwe, futhi ekugcineni ingxenye yembobo eyenziwe ngensimbi (igroove) iyagcinwa.Ukuze ulawule ukukhiqizwa kwamabhodi ensimbi anengxenye yembobo, abakhiqizi bebhodi lesifunda ngokuvamile bathatha izinyathelo ezithile ngenxa yezinkinga zenqubo lapho kuphambana khona izimbobo ezinengxenye ezinensimbi kanye nezimbobo ezingezona ezensimbi.Imbobo eyinsimbi eyenziwe ngensimbi...
- I-PCB SURFACE FINISHING, UBUHLE KANYE NEBUBI
Noma ubani ohilelekile embonini yebhodi lesekethe ephrintiwe (PCB) uyaqonda ukuthi ama-PCB aneziqephu zethusi endaweni yawo.Uma zishiywe zingavikelekile khona-ke ithusi lizokhipha i-oxidize futhi liwohloke, okwenza ibhodi lesifunda lingasebenzi.Isiphetho esingaphezulu sakha ukusebenzelana okubalulekile phakathi kwengxenye ne-PCB.Isiphetho sinemisebenzi emibili ebalulekile, ukuvikela ukujikeleza kwethusi okuveziwe kanye ...
- I-A&Q ye-PCB (2)
9. Kuyini isinqumo?Impendulo: Phakathi nebanga elingu-1mm, ukulungiswa kwemigqa noma imigqa yesikhala engakhiwa ukuphikiswa kwefilimu eyomile nakho kungavezwa ngosayizi ophelele wemigqa noma izikhala.Umehluko phakathi kwefilimu eyomile nokuqina kwefilimu yokumelana Ukuqina kwefilimu ye-polyester kuhlobene.Ukuqina kwesendlalelo sefilimu yokumelana, kuyancipha ukulungiswa.Lapho ukukhanya...
- Ibhodi le-Ceramic PCB
Amabhodi wesifunda se-Ceramic empeleni enziwe ngezinto zobumba ze-elekthronikhi futhi angenziwa abe yizimo ezihlukahlukene.Phakathi kwabo, ibhodi lesifunda se-ceramic linezici ezivelele kakhulu zokumelana nokushisa okuphezulu kanye nokufakwa kukagesi okuphezulu.Inezinzuzo zokungaguquguquki kwe-dielectric ephansi, ukulahleka kwe-dielectric ephansi, ukuhanjiswa okuphezulu kwe-thermal, ukuzinza okuhle kwamakhemikhali, nokunwetshwa okufanayo kokushisa ...
- Indlela yokwenza i-pcb kuphaneli?
1. Uhlaka lwangaphandle (uhlangothi olubambayo) lwephaneli Yebhodi Lesifunda Eliphrintiwe kufanele lusebenzise idizayini evala iluphu ukuze kuqinisekiswe ukuthi ijigsaw ye-PCB ngeke ikhubazekile ngemva kokulungiswa endaweni;2. Ububanzi bephaneli ye-PCB ≤260mm (umugqa we-SIEMENS) noma ≤300mm (umugqa we-FUJI);uma ukukhishwa okuzenzakalelayo kuyadingeka, ububanzi bephaneli ye-PCB× ubude ≤125 mm×180 mm;3. Umumo we-PCB jigsaw kufanele usondele eduze kwesikwele ngokungenzeka...
- Indlela yokuvimbela i-PCB board warping ngesikhathi senqubo yokukhiqiza
I-SMT(Printed Circuit Board Assembly, PCBA) ibizwa nangokuthi ubuchwepheshe be-surface mount.Phakathi nenqubo yokukhiqiza, i-solder paste iyashiswa futhi incibilike endaweni yokushisa, ukuze amaphedi e-PCB ahlanganiswe ngokuthembekile nezingxenye ze-surface mount ngokusebenzisa i-solder paste alloy.Le nqubo siyibiza ngokuthi i-reflow soldering.Iningi lamabhodi esekethe lithambekele ekugobeni nasekwenzeni ibhodi uma lihlehliswa...
- I-HDI board-high density interconnect
Ibhodi le-HDI, ukuminyana okuphezulu kokuxhumana okuphrintiwe ibhodi lesifunda Amabhodi e-HDI angobunye bobuchwepheshe obukhula ngokushesha kuma-PCB futhi manje butholakala e-ABIS Circuits Ltd. Amabhodi e-HDI aqukethe ama-vias angaboni kanye/noma angcwatshwe, futhi ngokuvamile aqukethe ama-microvias angu-0.006 noma amancane ububanzi.Banobuningi besifunda obuphakeme kunamabhodi wesifunda wendabuko.Kunezinhlobo eziyisi-6 ezihlukene zamabhodi we-HDI PCB, ukusuka phezulu kuye ku-su...
