Inganda za PCB zakoresheje umwanya munini utezimbere ibikoresho bitanga igihombo gito cyo kwerekana ibimenyetso. Kumuvuduko mwinshi hamwe nibishushanyo byinshi, igihombo kizagabanya intera yerekana ibimenyetso hamwe nibimenyetso bigoreka, kandi bizashiraho gutandukana kwangiza bishobora kugaragara mubikorwa bya TDR. Mugihe dushushanya inama yumuriro ucapwe kandi dutezimbere imirongo ikorera mumirongo miremire, irashobora kuba igerageza guhitamo umuringa ushoboka mubihe byose utera.

Mugihe ari ukuri ko umuringa ubugome butera impongano yinyongera nigihombo, fiil yumuringa wawe yoroshye cyane? Hariho uburyo bworoshye ushobora gukoresha kugirango batsinde igihombo udahisemo ultra-yoroshye umuringa kuri buri gishushanyo? Tuzareba izi ngingo muriki kiganiro, kimwe nibyo ushobora gushakisha niba utangiye guhaha ibikoresho bya PCB.

Ubwoko bwaPCB Umuringa

Mubisanzwe iyo tuvuganye numuringa kubikoresho bya PCB, ntabwo tuvuga ubwoko bwihariye bwumuringa, tuvuga gusa ububi bwayo. Uburyo butandukanye bwo kubitsa butanga Filime hamwe nindangagaciro zitandukanye zinyuranye, zishobora gutandukanywa neza mumico ya electron (sem). Niba ugiye gukorera mumikino myinshi (mubisanzwe 5 ghz wifi cyangwa hejuru) cyangwa kumuvuduko mwinshi, hanyuma witondere ubwoko bwumuringa bwerekanwe muri datasheet yawe.

Kandi, menya neza ko usobanukiwe ibisobanuro byindangagaciro za DK muri datasheet. Reba iki kiganiro cya Podcast hamwe na John Coorrod kuva Rogers kugirango umenye byinshi kubyerekeye ibisobanuro bya DK. Ukizirikana ibyo, reka turebe bumwe muburyo butandukanye bwa PCB umuringa.

Amashanyarazi

Muri iki gikorwa, ingoma irazunguruka mu gisubizo cya electrolytic, kandi imashini ya electrodeposition ikoreshwa kuri "gukura" umuringa umuringa ku ngoma. Mugihe Ingoma izunguruka, film ya repper yavuyemo buhoro buhoro kuri roller, itanga urupapuro rukomeza rushobora kuzunguruka nyuma kumurongo. Uruhande rw'ingoma rw'umuringa ruzahuza cyane n'ingoma y'ingoma, mu gihe uruhande rwagaragaye ruzakomeza kubaho.

Amashanyarazi ya PCB Umuringa

Amashanyarazi.
Kugirango ukoreshwe muburyo busanzwe bwa PCB, uruhande rutoroshye rwumuringa uzabanza guhuzwa nubusabane-resit. Umuringa usigaye ugaragara (uruhande rw'ingoma) azakenera guhindurwa mu buryo budashoboka. Ibi bizemeza ko bishobora guhuzwa nikirere gikurikira muri Stactup.

Hejuru-yavuwe ninkoko

Sinzi ijambo ryiza rikubiyemo ubwoko bwose butandukanye buvuweUmuringa, bityo umutwe wavuzwe haruguru. Ibi bikoresho by'umuringa bizwi cyane ku buryo butandukanye, nubwo ibindi bitandukanye bihari (reba hano hepfo).

Hindura firya ivuwe Koresha uburyo bwo hejuru bukoreshwa kuruhande rwiburyo bworoshye (kuruhande rwingoma) ya electrodepode page. Igice cyo kuvura ni ugukundana noroheje bikongeje nkana umuringa, bityo bizagira ibyo ahimbaza imirire. Ubuvuzi kandi bukora nkinzitizi ya okiside irinda ruswa. Iyo umuringa ukoreshwa mugukora panels Laminate, uruhande ruvuwe ruhujwe nimirire, kandi ibisigaye bikaze bikomeza kugaragara. Uruhande rwashyizwe ahagaragara ntiruziho gukomera mbere ya ETCHING; Bizaba bimaze kugira imbaraga zihagije zo guhuza kumurongo ukurikira muri stactup.

Ibitandukanya bitatu kuri rever bavuwe umuringa fiil harimo:

Ubushyuhe bwinshi bwo kuramba (Hte) Umuringa: Iyi ni igorofa ya electrodepod yuzuza hamwe na IPC-4562 icyiciro cya 3. Isura yerekanwe nayo irafatwa hamwe na bariyeri ya okiside kugirango irinde ruswa mugihe cyo kubika.
Gufatwa kabiri: Muri iyi file yumuringa, ubuvuzi bukoreshwa kumpande zombi za firime. Ibi bikoresho rimwe na rimwe byitwa ingoma bivurwa.
Umuringa wo kurwanya: Ibi mubisanzwe bishyirwa ahagaragara nkumuringa wavuwe. Uyu muringa ukoresha ibyuma hejuru kuruhande rwa matte yumuringa, hanyuma uhindagurika kurwego rwifuzwa.
Gusaba hejuru muri ibi bikoresho byumuringa biragenda neza: Ihuriro ryiyongereyeho ubwogero bwa electrolyte ikoresha ibyorezo byumuringa, bikurikirwa nigice cyimbuto za bariyeri, hanyuma amaherezo ya firime yo kurwanya.

PCB Umuringa

Uburyo bwo kuvura hejuru yumuringa. [Inkomoko: PYTEL, STEVEN G., et al. "Isesengura ry'ubuvuzi bw'umuringa n'ingaruka zo kwamamaza ibimenyetso." Muri 2008 58 ibice bya elegitoroniki hamwe ninama ikoranabuhanga, pp. 1144-1149. Ieee, 2008.]
Hamwe nibikorwa, ufite ibikoresho bishobora gukoreshwa byoroshye muburyo busanzwe bwo guhimba hamwe nibikoresho bike byo gutunganya.

Umuringa wuzuye

Amavuta yazengurutse umuringa azanyura umuzingo wumuringa wumuringa unyuze kuri rollers, izakonje-ikonjagura urupapuro rwumuringa. Ubuvumo bwurupapuro rwabikuyeho ruzatandukana bitewe nibipimo bya roshull (umuvuduko, igitutu, nibindi).

Urupapuro rwavuye rushobora kuba rworoshye, kandi ibikoresho biragaragara hejuru yurupapuro rwumuringa. Amashusho ahari yerekana kugereranya hagati yinzoka yumuringa hamwe numugozi uhamye.

PCB Umuringa Fiil Kugereranya

Umuringa muto
Ibi ntabwo byanze bikunze ubwoko bwumuringa wakwihimba hamwe nubundi buryo. Umuringa muto-umuringa ni electrodepodsited umuringa ufatwa kandi ugahindurwa nuburyo bwa micro-rougherning kugirango utange ubukana buke cyane hamwe nibibazo bihagije hamwe na roughening ihagije yo gusohora. Inzira yo gukora iyi foper yumuringa isanzwe. Izi nzego zikunze gutondekanya nkuko ultra-fames prof (ulp), umwirondoro muto cyane (VLP), kandi byoroshye-umwirondoro (LP, hafi mibiro 1 ugereranije ubukana).

Kuki umuringa wakoreshejwe mukora pcb?

Umuringa wa Fopper yakoreshejwe mu ntangiriro z'umuriro
