Ukuvela kokukhubazeka kukathayela kuvuliwe PCB ngokuvamile kuhlobene nokuhlanzeka kwe-PCB engenalutho ebhodini. Uma kungekho ukungcola, ngokuyisisekelo ngeke kube khona ukukhubazeka kothayela. Okwesibili, lapho kusetshenziswa ithini, ukugeleza uqobo kubi, izinga lokushisa, njll. Ngakho-ke ukukhubazeka kwethini likagesi elivamile lamabhodi wesifunda aphrintiwe kubonakala kakhulu kulawa maphuzu alandelayo:

1, ukumbozwa kwepuleti ebusweni kunokungcola kwezinhlayiyana, noma i-substrate enqubeni yokukhiqiza inezinhlayiya ezipholishiwe ezisele ebusweni bomugqa.

2. Ingaphezulu lebhodi limbozwe ngamafutha, ukungcola namanye amaswidi, noma izinsalela zikawoyela wezicucu

3, ebusweni ugesi ishidi ayikwazi ukuba tin, le enamathela ebusweni has kuyizinhlayiyana ukungcola.

4.

I-5, i-substrate noma izingxenye ze-tin surface oxidation ne-copper surface dark situation is serious.

I-6, uhlangothi olulodwa lwenhlanganisela luphelele, uhlangothi olulodwa lwengubo lubi, onqenqemeni lomgodi ongase ube namandla unezimo ezisobala ezisobala.

I-7, imbobo engaba namandla ephansi inesimo somphetho osobala ocacile, ukumboza okuphezulu okungahle kube khona, ukushisa kwepuleti.

8, inqubo ye-welding ayiqinisekisi ukushisa okwanele noma isikhathi, noma akuyona ukusetshenziswa okulungile kokuhamba

I-9, indawo ephansi engaba nendawo enkulu yothayela, ibhodi linombala omnyama obomvu noma obomvu, uhlangothi olulodwa lwengubo luphelele, uhlangothi olulodwa lwenwele alubi.

Izizathu zebhodi lesifunda elibi libonakala kakhulu kulawa maphuzu alandelayo:

1. Ukungalingani kokubhalwa ketshezi lokugeza, ukuminyana kwamanje kuncane kakhulu, isikhathi sokufaka sifushane kakhulu.

2. Ambalwa kakhulu ama-anode angasatshalaliswa ngokungalingani.

3. Inani elincane noma eleqile le-tin gloss.

4. I-anode yinde kakhulu, ukuminyana kwamanje kuphakeme kakhulu, ukuminyana kwentambo kuncane kakhulu, futhi i-ejenti ye-optical ayilungiswanga kahle.

5. Ifilimu eliyinsalela lasendaweni noma into ephilayo ngaphambi kokufakwa.

6. Ubuningi bamanje buphakeme kakhulu futhi isisombululo seplating asanele.
