Yintoni i-PCB Plating?
I-PCB plating yinkqubo yokufaka umaleko omncinci wesinyithi phezu komphezulu we-PCB substrate kunye neendlela zokuhambisa umoya. Olu plating luneenjongo ezininzi, kubandakanya ukuphucula ukuhanjiswa komoya weendlela, ukukhusela iindawo zobhedu eziveziweyo kwi-oxidation kunye nokugqwala, kunye nokubonelela ngomphezulu wokufaka izinto ze-elektroniki ebhodini. Inkqubo yokufakela umoya idla ngokwenziwa kusetyenziswa iindlela ezahlukeneyo ze-electrochemical, ezifana ne-electroless plating okanye i-electroplating, ukuze kufezekiswe ubukhulu kunye neempawu ezifunekayo zomaleko ofakelweyo.
Ukubaluleka kwe-PCB Plating
Ukufakwa kwe-PCB kubalulekile ngezizathu ezahlukeneyo. Okokuqala, kuphucula ukuhanjiswa kweendlela zobhedu, kuqinisekisa ukuba imiqondiso yombane inokuhamba kakuhle phakathi kwezinto. Oku kubaluleke kakhulu kwizicelo ezisebenzisa amaza aphezulu kunye nesantya esiphezulu apho ukuthembeka kwesignali kubaluleke kakhulu. Ukongeza, umaleko ofakwe i-plated usebenza njengomqobo kwimiba yokusingqongileyo efana nokufuma kunye nezinto ezingcolisayo, ezinokuthi zonakalise ukusebenza kwe-PCB ngokuhamba kwexesha. Ngaphezu koko, ukufakwa kwe-plated kubonelela ngomphezulu wokutywina, okuvumela ukuba izinto ze-elektroniki zinamathele ngokukhuselekileyo ebhodini, zenze uqhagamshelo lombane oluthembekileyo.
Iintlobo zePCB Plating
Kukho iintlobo ezahlukeneyo zokuplata ezisetyenziswa kwimveliso ye-PCB, nganye ineempawu zayo ezizodwa kunye nezicelo zayo. Ezinye zezona ntlobo zixhaphakileyo zokuplata kwe-PCB ziquka:
1. Igolide yokuntywiliselwa kweNickel engena-Electroless (ENIG): I-ENIG plating isetyenziswa kakhulu kwimveliso ye-PCB ngenxa yokumelana kwayo nokugqwala kunye nokukwazi kwayo ukunyibilikisa. Iqulathe umaleko omncinci we-nickel engena-electron elandelwa ngumaleko wegolide yokuntywilisela, enika umphezulu othe tyaba nogudileyo wokunyibilikisa ngelixa ikhusela ubhedu olungaphantsi kwi-oxidation.
2. Igolide Egqunywe Nge-Electroplated: I-electroplated gold plating yaziwa ngokuba ne-conductivity yayo egqwesileyo kunye nokumelana nokungcoliswa, okwenza ukuba ifaneleke ukusetyenziswa apho kufuneka ukuthembeka okuphezulu kunye nexesha elide. Ihlala isetyenziswa kwizixhobo ze-elektroniki eziphezulu kunye nezicelo zeenqwelo moya.
3. I-Tin efakwe ngombane: I-Tin plating isetyenziswa kakhulu njengendlela engabizi kakhulu kwii-PCB. Inika ukunyibilika okuhle kunye nokumelana nokugqwala, okwenza ifaneleke kwiinjongo eziqhelekileyo apho ixabiso liyinto ebalulekileyo.
