Gusaba
Reka tumenye ubumenyi bwubunini bwa pcb.
Umuringa wumuringa nkumubiri uyobora pcb, gufatana byoroshye kurwego rwimikorere, kwangirika kwinzira yumuzunguruko. Ubunini bwumuringa wumuringa bugaragarira muri oz (oz), 1oz = 1.4mil, kandi uburebure buringaniye bwa fayili yumuringa bugaragarira muburemere kuri buri gice agace na formula: 1oz = 28.35g / FT2 (FT2 ni metero kare, metero kare 1 = 0.09290304㎡).
Impapuro mpuzamahanga z'umuringa pcb zikoreshwa cyane: 17.5um, 35um, 50um, 70um.Mubisanzwe, abakiriya ntibavuga amagambo yihariye mugihe bakora pcb.Uburebure bwumuringa bwimpande imwe nubwa kabiri ni 35um, ni ukuvuga umuringa 1 amp.Birumvikana ko bimwe mubibaho byihariye bizakoresha 3OZ, 4OZ, 5OZ ... 8OZ, nibindi, ukurikije ibisabwa nibicuruzwa kugirango uhitemo ubunini bwumuringa.
Ubusanzwe umuringa wumuringa wububiko bumwe kandi bubiri PCB ni hafi 35um, naho ubundi umuringa wuburebure ni 50um na 70um.Uburebure bw'umuringa bwo hejuru bw'isahani myinshi ni 35um, naho umuringa w'imbere ni 17.5um.Ikoreshwa ryumuringa wumuringa wa Pcb ahanini biterwa no gukoresha PCB na voltage ya signal, ubunini bwubu, 70% byubuyobozi bwumuzunguruko bukoresha 3535um umuringa wa fayili.Birumvikana, kubigezweho ni binini cyane byumuzunguruko, uburebure bwumuringa nabwo buzakoreshwa 70um, 105um, 140um (bike cyane)
Gukoresha ikibaho cya Pcb biratandukanye, gukoresha uburebure bwumuringa nabyo biratandukanye.Kimwe nibicuruzwa bisanzwe nibicuruzwa byitumanaho, koresha 0.5oz, 1oz, 2oz;Kuri byinshi bigezweho, nkibicuruzwa bikomoka kuri voltage nyinshi, ikibaho gitanga amashanyarazi nibindi bicuruzwa, muri rusange koresha 3oz cyangwa hejuru ni ibicuruzwa byumuringa mwinshi.
Inzira yo kumanika imbaho zumuzunguruko muri rusange nuburyo bukurikira:
1. Gutegura: Tegura imashini imurika n'ibikoresho bisabwa (harimo imbaho z'umuzunguruko hamwe na fayili y'umuringa igomba kumurika, amasahani yo gukanda, n'ibindi).
2. Kuvura isuku: Sukura kandi uhumane hejuru yubutaka bwumuzunguruko hamwe na fayili yumuringa kugirango ukande kugirango ugurishe neza kandi uhuze.
3. Kumurika: Koresha urumuri rwumuringa hamwe ninama yumuzunguruko ukurikije ibisabwa, mubisanzwe urwego rumwe rwumuzunguruko hamwe nigice kimwe cyumuringa wumuringa ushyizwe hamwe, hanyuma amaherezo haboneka ikibaho cyumuzunguruko.
4. Guhagarara no gukanda: shyira ikibaho cyumuzunguruko cyometse kumashini ikanda, hanyuma ukande ku cyerekezo cyumuzunguruko cyinshi ushyira icyapa.
5. Uburyo bwo gukanda: Mugihe cyagenwe nigitutu cyagenwe, ikibaho cyumuzunguruko hamwe numuringa wumuringa bikanda hamwe nimashini ikanda kugirango ihuze cyane.
6. Kuvura gukonjesha: Shira ikibaho cyumuzunguruko gikanda kuri platifomu yo gukonjesha kugirango ukonje, kugirango gishobore kugera ku bushyuhe buhamye n’umuvuduko.
7.Ibikorwa byakurikiyeho: Ongeraho ibintu birinda ibintu hejuru yumurongo wumuzunguruko, kora gutunganya nyuma nko gucukura, gushiramo pin, nibindi, kugirango urangize ibikorwa byose byubuyobozi bwumuzunguruko.
Ibibazo
Ubunini bwumuringa ukoreshwa mubisanzwe biterwa nubu bugomba kunyura muri PCB.Umubyimba usanzwe wumuringa ni hafi 1,4 kugeza kuri 2.8 (1 kugeza 2 oz)
Umubyimba muto wa PCB wumuringa kuri laminate yambaye umuringa uzaba 0.3 oz-0.5oz
Ubunini ntarengwa PCB nijambo rikoreshwa mugusobanura ko ubunini bwikibaho cyacapwe cyoroshye cyane kuruta PCB isanzwe.Ubunini busanzwe bwikibaho cyumuzunguruko ni 1.5mm.Umubyimba ntarengwa ni 0.2 mm kubenshi mubibaho byumuzunguruko.
Bimwe mu bintu byingenzi biranga harimo: kuzimya umuriro, guhora dielectric, gutakaza ibintu, imbaraga zingana, imbaraga zo gukata, ubushyuhe bwikirahure, nuburyo umubyimba uhinduka hamwe nubushyuhe (coefficient ya Z-axis).
Nibikoresho byo kubika bihuza ingirangingo zegeranye, cyangwa intangiriro nigice, murwego rwa PCB.Ibikorwa byibanze byimyiteguro ni uguhuza urufatiro kurundi rufatiro, guhambira intangiriro kumurongo, gutanga insulasiyo, no kurinda ikibaho cyabantu benshi kwirinda-kuzenguruka.
