3 Inzira yo kuvura hejuru ya Pcb: zahabu yibiza na OSP

Mugihe uhisemo uburyo bwo kuvura hejuru (nka zahabu yo kwibiza, OSP, nibindi) kuri PCB yawe igizwe na 3, birashobora kuba umurimo utoroshye. Kubera ko hari amahitamo menshi, ni ngombwa guhitamo uburyo bukwiye bwo kuvura hejuru kugirango uhuze ibisabwa byihariye.Muri iyi nyandiko ya blog, tuzaganira ku buryo bwo guhitamo uburyo bwiza bwo kuvura hejuru ya PCB yawe igizwe n’ibice 3, tugaragaza ubuhanga bwa Capel, isosiyete izwiho kugenzura ubuziranenge bwo mu rwego rwo hejuru hamwe n’ibikorwa bya PCB byateye imbere.

Capel irazwi cyane kubera PCBs zikomeye, PCB zoroshye na PCI za HDI. Hamwe nimpamyabumenyi yatanzwe hamwe nuburyo butandukanye bwo gukora PCB yateye imbere, Capel yigaragaje nkumuyobozi winganda. Noneho reka turebe neza ibintu tugomba gusuzuma mugihe uhisemo kurangiza hejuru ya PCB-3.

1. Gushyira mu bikorwa n'ibidukikije

Ubwa mbere, ni ngombwa kumenya porogaramu n'ibidukikije bya 3-PCB. Uburyo butandukanye bwo kuvura hejuru butanga uburyo butandukanye bwo kurinda ruswa, okiside nibindi bintu bidukikije. Kurugero, niba PCB yawe izahura nibihe bibi, nkubushyuhe bwinshi cyangwa ubushyuhe bukabije, birasabwa guhitamo uburyo bwo kuvura hejuru butanga uburinzi bwongerewe imbaraga, nka zahabu yo kwibiza.

2. Igiciro nigihe cyo gutanga

Ikindi kintu cyingenzi tugomba gusuzuma ni ikiguzi nigihe cyo kuyobora kijyanye nuburyo butandukanye bwo kuvura. Ibiciro byibikoresho, ibisabwa nakazi hamwe nigihe cyo gutanga umusaruro biratandukanye kuri buri gikorwa. Izi ngingo zigomba gusuzumwa ukurikije ingengo yimari yawe nigihe ntarengwa cyumushinga kugirango ufate icyemezo kiboneye. Ubuhanga bwa Capel mubikorwa byiterambere byiterambere bitanga ibisubizo bihendutse kandi mugihe gikenewe kugirango PCB ikeneye gutegurwa.

3. Kwubahiriza RoHS

RoHS (Kubuza Ibintu Byangiza) kubahiriza ni ikintu cyingenzi, cyane cyane niba ibicuruzwa byawe bigenewe isoko ryiburayi. Uburyo bumwe bwo kuvura bushobora kuba burimo ibintu bishobora guteza imipaka ya RoHS. Ni ngombwa guhitamo inzira yo kuvura hejuru yubahiriza amabwiriza ya RoHS. Ubwitange bwa Capel kugenzura ubuziranenge butuma uburyo bwo kuvura hejuru bwubahirizwa na RoHS, bikaguha amahoro yo mumutima mugihe cyo kubahiriza.

4. Kugurisha no guhuza insinga

Ibishobora kugurishwa hamwe no guhuza insinga biranga PCB nibyingenzi byingenzi. Uburyo bwo kuvura hejuru bugomba kwemeza neza kugurishwa, bikavamo kugurisha neza mugihe cyo guterana. Byongeye kandi, niba igishushanyo cya PCB kirimo guhuza insinga, inzira yo kuvura hejuru igomba kunoza ubwizerwe bwimigozi. OSP (Organic Solderability Preservative) ni amahitamo azwi cyane kubera kugurishwa kwayo neza no guhuza insinga.

5. Impuguke ninama

Guhitamo uburyo bwiza bwo kuvura kubutaka bwawe bwa PCB-3 birashobora kugorana, cyane cyane niba uri mushya mubikorwa bya PCB. Gushakisha inama zinzobere ninkunga mubigo byizewe nka Capel birashobora koroshya inzira yo gufata ibyemezo. Itsinda ry'inararibonye rya Capel rirashobora kukuyobora muburyo bwo gutoranya no gutanga inama nziza yo kuvura hejuru ukurikije ibyo usabwa byihariye.

Muncamake, guhitamo uburyo bukwiye bwo kuvura kubice 3 bya PCB nibyingenzi kubikorwa byiza no kuramba.Ibintu nkibisabwa nibidukikije, ikiguzi nigihe cyo kuyobora, kubahiriza RoHS, kugurisha hamwe no guhuza insinga bigomba gusuzumwa neza.Kugenzura ubuziranenge bwa Capel, ibyemezo byemewe hamwe nibikorwa byogukora PCB bigufasha guhuza ibyifuzo byawe byo gutegura. Baza impuguke za Capel kandi wungukire kubumenyi bwabo nuburambe.Wibuke ko uburyo bwatoranijwe bwo gutunganya ibintu bushobora kugira ingaruka zikomeye kumikorere rusange no kuramba kwa PCB-3.
