Ibibaho byinshi byumuzunguruko hagati TG150 8 ibice

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 bwuruhande rumwe kandi bubiri 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.

2.

3. Kumurika: Shyira kumurongo wumuringa hamwe ninama yumuzunguruko ukurikije ibisabwa, mubisanzwe igice kimwe cyumuzunguruko hamwe nigice kimwe cyumuringa wumuringa bishyirwa hamwe, hanyuma amaherezo haboneka ikibaho cyumuzunguruko.

.

5. Uburyo bwo gukanda: Mugihe cyagenwe nigitutu cyagenwe, ikibaho cyumuzunguruko hamwe numuringa wumuringa bikanda hamwe nimashini ikanda kugirango bihuze cyane.

.

7.Ibikorwa byakurikiyeho: Ongeraho ibintu birinda ibintu hejuru yumurongo wumuzunguruko, kora gutunganya nyuma nko gucukura, gushiramo pin, nibindi, kugirango urangize ibikorwa byose byubuyobozi bwumuzunguruko.
