Okuphelele PCB Inqubo ye-electroplating ifaka ukwelashwa kwangemva kokufakwa kwe-electroplating. Ngokubanzi, yonke i-electroplating iyelashwa ngemuva kokuqothulwa. Ukwelashwa okulula kakhulu okubandakanya ukwelashwa kubandakanya ukufaka amanzi ashisayo nokuwomisa. Futhi ukumbozwa okuningi kudinga nokuhamba, ukufaka umbala, ukudaya, ukufaka uphawu, ukudweba nokunye ukucubungula, ukuze wenze ukusebenza kokumboza kudlale kangcono futhi kuqinise.

Ungabhekana kanjani ne-PCB ngemuva kwe-electroplating

Izindlela zokwelashwa ngemuva kokufakwa kwesinye isigaba zingahlukaniswa ngezigaba eziyi-12 ezilandelayo:

1, ukuhlanza;

2, yomile;

3, ukususwa kwe-hydrogen;

4, ezipholisha (wokucwebezelisa ngomshini nokupholisha kagesi);

5, ukudlula;

6, ukufaka umbala;

7, ukudaya;

8, kuvaliwe;

9, ukuvikelwa;

10. Ukudweba;

11, ukususwa kokumboza okungafanelekile;

12, ukubuyiselwa kokugeza.

Ngokwenhloso yokusebenzisa noma ukuklanywa kwemikhiqizo yensimbi noma engeyona eyensimbi, ukwelashwa okulandelayo kungahlukaniswa ngezigaba ezintathu, okungukuthi ukwenza ngcono noma ukuqinisa ukuvikelwa, ukuhlobisa nokusebenza.

(1) Ukuvikelwa kwangemva kokwelashwa

Ngaphandle kokufakwa kwe-chrome, zonke ezinye izinto zokuvikela, lapho zisetshenziswa njengokumboza komhlaba, kufanele ziphathwe kahle ngemuva kokugcina noma ukuthuthukisa izakhiwo zazo zokuzivikela. Indlela ejwayelekile kakhulu yokwelashwa ngemuva kokwelashwa yi-passivation. Ukuvikela izidingo eziphakeme zokucutshungulwa kwendawo yokumboza, ngokwesibonelo, ukumboza ukucutshungulwa kokukhanya okukhanyayo, kusuka ekuvikelweni kwemvelo nokucatshangelwa kwezindleko, kungasebenzisa ukumboza kwamanzi okusobala.

(2) ukwelashwa kokuhlobisa okuthunyelwe

Ukwelashwa kokuhlobisa ngemuva kwenqubo kuyindlela ejwayelekile ekulayisheni okungeyona eyensimbi. Isibonelo, ukufakwa kwegolide mbumbulu, isiliva mbumbulu, ithusi lasendulo, ukuxubha, ukufaka umbala noma ukudaya nokunye ukwelashwa kwezobuciko. Lezi zindlela zokwelashwa zidinga nokuthi ingaphezulu ligcotshwe ngengubo ebonakalayo. Kwesinye isikhathi sebenzisa ukumboza okusobala kwe-chromatic noma, ngokwesibonelo kopisha i-aureate, obomvu, oluhlaza okotshani, onsomi ulinde ukumbozwa kombala.

(3) Ukusebenza okusebenza ngemuva

Eminye imikhiqizo ye-electroplating engeyona eye-metallic yenzelwe izidingo zokusebenza, kanti okunye ukwelashwa okusebenzayo kuyadingeka ngemuva kwe-electroplating. Ngokwesibonelo, njengoba ebusweni enamathela kazibuthe uvikele ungqimba, njengoba ebusweni solder enamathela ka Welding enamathela, njll
