Gusaba

Inganda zigenzura inganda PCB ni ikibaho cyumuzingo cyacapishijwe gikoreshwa muri sisitemu yo kugenzura inganda kugenzura no kugenzura ibipimo bitandukanye nkubushyuhe, ubushuhe, umuvuduko, umuvuduko, nibindi bintu bihinduka.Izi PCB zisanzwe kandi zashizweho kugirango zihangane n’ibidukikije bikaze nk’inganda ziboneka mu nganda zikora inganda, inganda z’imiti, n’imashini zikora inganda.Kugenzura inganda PCB mubusanzwe ikubiyemo ibice nka microprocessor, programable logic controller (PLCs), sensor, hamwe na moteri bifasha kugenzura no kunoza inzira zitandukanye.Bashobora kandi gushiramo imiyoboro yitumanaho nka Ethernet, CAN, cyangwa RS-232 kugirango bahanahana amakuru nibindi bikoresho.Kugirango habeho kwizerwa no gukora ubudahwema, kugenzura inganda PCBs zipimwa cyane hamwe ningamba zo kugenzura ubuziranenge mugihe cyo gukora no gukora.Bagomba kandi kubahiriza amahame yinganda nka UL, CE, na RoHS, nibindi.

Inzira ndende PCB ni icapiro ryumuzunguruko wanditseho ibice byinshi byumuringa hamwe nibikoresho byamashanyarazi byashyizwe hagati yabyo.Mubisanzwe bafite ibice birenga 6 kandi birashobora kuzamuka bigera kuri 50 cyangwa birenga, bitewe nuburemere bwibishushanyo mbonera.Inzira ndende PCBs ningirakamaro mugushushanya ibikoresho byoroheje bisaba umubare munini wibigize.Bafasha guhuza imiterere yinama yumuzunguruko muguhuza inzira igoye no guhuza binyuze mubice byinshi.Ibi bivamo muburyo bworoshye kandi bunoze bubika umwanya kurubaho.Izi mbaho zisanzwe zikoreshwa mubikorwa bya elegitoroniki byo mu rwego rwo hejuru, nk'ikirere, icyogajuru, n'inganda z'itumanaho.Bakenera ubuhanga buhanitse bwo gukora, nko gucukura lazeri no kugenzura inzira ya impedance, kugirango barebe neza kandi byizewe.Bitewe nuburyo bugoye, gushushanya no gukora ibice byo hejuru PCBs birashobora kuba bihenze kandi bitwara igihe kuruta PCB zisanzwe.Byongeye kandi, uko PCB ifite ibice byinshi, niko bishoboka cyane ko habaho amakosa mugihe cyo gukora no gukora.Nkigisubizo, urwego rwo hejuru PCBs rusaba igeragezwa ryinshi ningamba zo kugenzura ubuziranenge kugirango zizere imikorere yazo kandi zizewe.

Countersink PCB bivuga inzira yo gucukura umwobo mu kibaho hanyuma ugakoresha diameter nini kugirango ukore ikiruhuko cya conique kizengurutse umwobo.Ibi akenshi bikorwa mugihe umutwe wa screw cyangwa bolt ukeneye guhindurwa hejuru ya PCB.Countersink isanzwe ikorwa mugihe cyo gucukura PCB, nyuma yumuringa umaze gutoborwa na mbere yuko ikibaho kinyura mu masoko yo kugurisha hamwe no gucapa silike.Ingano n'imiterere y'umwobo wa sun-sunk bizaterwa na screw cyangwa bolt ikoreshwa hamwe n'ubunini n'ibikoresho bya PCB.Ni ngombwa kwemeza ko uburebure bwimbitse na diameter bikwiye kugirango wirinde kwangiza ibice cyangwa ibimenyetso kuri PCB.Countersink PCB irashobora kuba tekinike yingirakamaro mugushushanya ibicuruzwa bisaba ubuso busukuye kandi buringaniye.Yemerera imigozi na bolts kwicara hamwe nibibaho, bigakora isura nziza cyane kandi ikarinda kwangirika cyangwa kwangirika kwiziritse.

Ibibazo

1.Ni iki isahani ya zahabu muri PCB?

Gushyira zahabu ni ubwoko bwa PCB burangiza, bizwi kandi nka nikel zahabu ya electroplating.Mubikorwa byo gukora PCB, isahani ya zahabu nugushira igice cya zahabu cyometse hejuru yumwenda wa nikel ukoresheje amashanyarazi.Gushyira zahabu birashobora kugabanywamo '' zahabu ikomeye isahani '' na '' isahani yoroshye ya zahabu ''.

2.Kuki zahabu ikoreshwa kuri PCB?

Bikunze gukoreshwa bifatanije na plaque ya nikel, urwego ruto rwa zahabu rurinda ibice kwangirika, ubushyuhe, kwambara no gufasha guhuza amashanyarazi yizewe.

3.Ni ubuhe buryo bukomeye PCB na zahabu yoroshye?

Isahani ikomeye ya zahabu ni electrodeposit ya zahabu yashizwemo ikindi kintu kugirango ihindure imiterere yizahabu.Isahani yoroshye ya zahabu niyo isukuye cyane ya electrodeposit;ni zahabu nziza rwose nta kongeramo ibintu byose bivanga

4.Ni ubuhe buryo bwo kubara muri PCB?

Umwobo wa Countersink ni umwobo umeze nka cone utabitswe cyangwa wacukuwe muri laminate ya PCB.Uyu mwobo wapanze utuma umutwe-shitingi wa soketi wumutwe winjizwa mumwobo wacukuwe.Countersinks yashizweho kugirango yemere bolt cyangwa screw kugumaho imbere hamwe nubuso bwateganijwe.

5.Ni ubuhe bwoko bwa comptersink umwobo dufite?

82degree, 90degree na 100degree
