Ni ukubera iki ibicuruzwa bya PCB byumuringa bisa hejuru?

Koresha PCBhejuru yububiko ni imwe mubisanzwe inenge nziza mubikorwa bya PCB.Kubera ibintu bigoye byo gutunganya umusaruro wa PCB no kubitunganya, cyane cyane mukuvura imiti itose, biragoye gukumira inenge yibibaho.

Igituba kuriUbuyobozi bwa PCBni mubyukuri ikibazo cyingufu zidahuza ku kibaho, kandi nukwagura, ikibazo cyubuziranenge bwubutaka ku kibaho, gikubiyemo ibintu bibiri:

1. Ikibazo cyisuku ya PCB;

2. Micro roughness (cyangwa ingufu zo hejuru) hejuru ya PCB;ibibazo byose byo guswera ku kibaho cyumuzunguruko birashobora kuvunagurwa nkimpamvu zavuzwe haruguru.Imbaraga zihuza hagati yigitereko ni mbi cyangwa nke cyane, mugikorwa cyakurikiyeho cyo gutunganya no gutunganya no guteranya biragoye kurwanya inzira yo gutunganya no gutunganya ibyakozwe mubitera impuzu, guhangayikishwa no gukanika ubushyuhe, nibindi, bikavamo ibintu bitandukanye impamyabumenyi yo gutandukana hagati yo gutwikira ibintu.

Ibintu bimwe bitera ubuziranenge bwubuso mubikorwa bya PCB no kubitunganya byavuzwe muri make kuburyo bukurikira:

Customer PCB substrate - ibibazo byo kuvura isahani yumuringa;Cyane cyane kubintu bimwe byoroheje (muri rusange munsi ya 0.8 mm), kubera ko gukomera kwa substrate ari bibi, gukoresha imashini ya brush brush brush, ntibishobora gukuraho neza substrate kugirango hirindwe okiside hejuru yumuringa wumuringa mugihe cyo gukora no gutunganya hamwe nuburyo bwihariye bwo gutunganya, mugihe urwego rworoshye, isahani yohasi iroroshye kuyikuramo, ariko gutunganya imiti biragoye, Kubwibyo, ni ngombwa kwitondera kugenzura mubikorwa no gutunganya, kugirango bidatera ikibazo yo kubira ifuro iterwa n'imbaraga zidahuza hagati yumuringa wa substrate wumuringa nu muringa wimiti;mugihe igicucu cyimbere cyijimye, hazabaho no kwirabura nabi no kwijimye, ibara ritaringaniye, hamwe no kwirabura kwaho.

Ubuso bwa PCB murwego rwo gutunganya (gucukura, kumurika, gusya, nibindi) biterwa namavuta cyangwa ubundi buryo bwo gutunganya ivumbi ryanduye ni bibi.

3. Isahani ya PCB yo kurohama isahani irakennye: umuvuduko wisahani yo gusya mbere yo kurohama umuringa ni munini cyane, bikaviramo guhindura umwobo, hamwe nu muringa wuzuye umuringa ku mwobo ndetse n’ibikoresho fatizo bitemba mu mwobo, bizatera ububobere. phenomenon ku mwobo mugikorwa cyo kurohama umuringa, isahani, gutera amabati no gusudira;Niyo isahani yohanagura idatera kumeneka kwa substrate, isahani irenze urugero ya brush izongera ubukana bwumwobo wumuringa, bityo rero mugihe cyo gukonjesha mikorobe, ifu yumuringa iroroshye kubyara ibintu bikabije bikabije, ngaho bizaba kandi ingaruka nziza;Kubwibyo rero, hakwiye kwitabwaho gushimangira igenzura ryuburyo bwa plaque ya brush, kandi ibipimo byerekana ibyapa bya brush birashobora guhindurwa mubyiza binyuze mukizamini cyo kwambara no gupima firime.

4. Ikibazo cya PCB cyogejwe: kubera ko gutunganya umuringa uremereye wa electroplating bigomba gutambutsa imiti myinshi yimiti ivura imiti, ubwoko bwose bwa acide-shingiro idafite ibinyabuzima bidafite imiti nkibiyobyabwenge, gukaraba mu maso ntibisukuye, cyane cyane guhindura umuringa uremereye wongeyeho abakozi, ntibishobora gutera kwanduzanya gusa, bizanatera inama y'ubutegetsi guhura nibikorwa bitunganijwe nabi cyangwa bibi byo kuvura, inenge idahwanye, itera zimwe mumbaraga zihuza;bityo rero, hakwiye kwitabwaho gushimangira igenzura ryo gukaraba, cyane cyane harimo kugenzura imigendekere y’amazi meza, ubwiza bw’amazi, igihe cyo gukaraba, nigihe cyo gutonyanga ibice;Cyane mu gihe cy'itumba, ubushyuhe buri hasi, ingaruka zo gukaraba zizagabanuka cyane, hakwiye kwitabwaho cyane kugenzura gukaraba.
