Ibikoresho fatizo bya PCB - Umuringa

Ibikoresho byingenzi bikoreshwa muri PCBs niumuringa, ikoreshwa mu kohereza ibimenyetso n'inzira. Muri icyo gihe, ifu y'umuringa kuri PCBs irashobora kandi gukoreshwa nk'indege yerekanwe kugira ngo igenzure inzitizi z'umurongo w'itumanaho, cyangwa nk'ingabo ikingira amashanyarazi (EMI). Muri icyo gihe, mubikorwa byo gukora PCB, imbaraga zishishwa, imikorere ya etching nibindi biranga ifu yumuringa nabyo bizagira ingaruka kumiterere no kwizerwa mubikorwa bya PCB. Ba injeniyeri ba PCB bakeneye gusobanukirwa nibi biranga kugirango barebe ko inzira ya PCB ishobora gukorwa neza.

Impapuro z'umuringa ku mbaho ​​zicapye zifite amashanyarazi ya electrolytike (amashanyarazi ya ED yumuringa) na kalendari yometseho umuringa (kuzunguruka anneal RA umuringa) ubwoko bubiri, ubwambere binyuze muburyo bwa electroplating uburyo bwo gukora, ubundi bukoresheje uburyo bwo kuzunguruka. Muri PCB zikomeye, amashanyarazi yumuringa ya electrolytike akoreshwa cyane cyane, mugihe umuringa uzengurutswe wumuringa ukoreshwa cyane cyane kubibaho byoroshye.

Kubisabwa mubibaho byacapwe, hari itandukaniro rikomeye hagati ya electrolytike na kalendari yumuringa. Umuringa wa electrolytike wumuringa ufite ibintu bitandukanye kubiranga byombi, ni ukuvuga, ubukana bwimiterere ibiri ya file ntabwo ari bumwe. Mugihe inshuro zumuzunguruko hamwe nibiciro byiyongera, ibiranga umuringa wumuringa birashobora kugira ingaruka kumikorere yumurambararo wa milimetero (mm Wave) hamwe numuvuduko mwinshi wa digitale (HSD). Ubuso bw'umuringa burashobora kugira ingaruka ku gutakaza PCB, guhuza icyiciro, no gutinda gukwirakwizwa. Ubuso bw'umuringa burashobora gutera itandukaniro mubikorwa kuva PCB imwe kurindi kimwe no gutandukana mumikorere y'amashanyarazi kuva PCB kurindi. Gusobanukirwa uruhare rwumuringa wumuringa mugukora cyane, imiyoboro yihuta irashobora gufasha gutezimbere no kugereranya neza igishushanyo mbonera kuva moderi kugeza kumuzunguruko nyirizina.

Ubuso bukabije bwumuringa wumuringa nibyingenzi mubikorwa bya PCB

Umwirondoro ugereranije ugereranije ufasha gushimangira ifatizo ryumuringa kuri sisitemu. Nubwo bimeze bityo ariko, umwirondoro utagaragara urashobora gusaba igihe kirekire, bishobora kugira ingaruka ku musaruro wibibaho no kumurongo neza. Kongera igihe cyo guswera bisobanura kwiyongera kuruhande rwumuyobora hamwe no gukomera kuruhande rukomeye. Ibi bituma umurongo mwiza wo guhimba no kugenzura impedance bigorana. Byongeye kandi, ingaruka zumuringa wumuringa kumurongo wagaragaye mugihe ibimenyetso byumuzunguruko byiyongera. Mugihe cyinshi, ibimenyetso byinshi byamashanyarazi byoherezwa hejuru yuyobora, kandi hejuru yuburiganya butera ikimenyetso gukora urugendo rurerure, bikaviramo kwiyongera cyangwa gutakaza. Kubwibyo, imikorere-yimikorere isaba imbaraga nkeya zumuringa hamwe na adhesion ihagije kugirango ihuze na sisitemu yo hejuru cyane.

Nubwo porogaramu nyinshi kuri PCB muri iki gihe zifite umubyimba wumuringa wa 1 / 2oz (hafi 18 mm), 1oz (hafi 35μm) na 2oz (hafi 70μm), ibikoresho bigendanwa nimwe mubintu bitera umubyimba wumuringa wa PCB kuba muto cyane 1μm, mugihe kurundi ruhande umubyimba wumuringa wa 100μm cyangwa urenga uzongera kuba ingirakamaro kubera porogaramu nshya (urugero: ibikoresho bya elegitoroniki yimodoka, amatara ya LED, nibindi). .

Hamwe niterambere rya milimetero 5G hamwe numuyoboro wihuse wihuse, icyifuzo cyibikoresho byumuringa bifite imyirondoro yo hasi biragenda byiyongera.
