Nyika yemagetsi yakafambira mberi zvikuru mumakumi emakore achangopfuura, uye kuseri kwechishamiso chega chega chemagetsi kune bhodhi redunhu rakadhindwa (PCB). Izvi zvidiki asi zvakakosha zvinoumba musana wezvinenge zvese zvemagetsi mudziyo. Mhando dzakasiyana dzePCB dzinosangana nezvinodiwa zvakasiyana, imwe mhando ndeye ENIG PCB.Mune ino blog, isu tichaongorora zvakadzama nezve ENIG PCB, ichiburitsa hunhu hwayo, mashandisiro uye kuti yakasiyana sei kubva kune mamwe marudzi ePCB.
1.Chii chinonzi kunyudza goridhe PCB?
Pano tichapa tarisiro yakadzama yeENIG PCBs, kusanganisira zvikamu zvadzo, kuvaka, uye electroless nickel kunyudza goridhe process inoshandiswa kugadzira. Vaverengi vanonzwisisa zvakajeka izvo zvakasarudzika izvo zvinoita kuti ENIG PCB ioneke.
ENIG ndiyo chidimbu che electroless nickel kunyudza goridhe plating, inova inowanzoshandiswa pamusoro pekurapa nzira mukugadzira PCB.Inopa mhinduro yakavimbika uye inodhura yekuvimbisa hupenyu hurefu uye kushanda kwemidziyo yemagetsi. ENIG PCBs anoshandiswa zvakanyanya mumaindasitiri akadai senharembozha, aerospace, zvemagetsi zvevatengi, uye zvishandiso zvekurapa.
ENIG PCBs inoumbwa nezvinhu zvitatu zvikuru: nickel, goridhe, uye barrier layer.Iyo yekuvharira layer inowanzo gadzirwa neatete tambo ye electroless nickel yakaiswa pamusoro pemhangura mitsetse nemapads ePCB. Iyi nickel layer inoshanda sechivhariso chekuparadzira, ichidzivirira mhangura kuti isafambe ichienda mudura regoridhe panguva yekuiswa kwegoridhe. Mushure mekushandisa nickel layer, hutete hwegoridhe hunoiswa pamusoro. Iyo yegoridhe layer inopa yakanakisa conductivity, durability uye corrosion resistance. Inopawo mwero wekudzivirira kubva kune oxidation, kuve nechokwadi chenguva refu PCB kuita uye kuvimbika.
Iyo nzira yekugadzira yeENIG PCB inosanganisira akati wandei matanho. Kutanga, iyo PCB inobatwa pamusoro uye kucheneswa kuti ibvise zvinosvibisa uye okisidhi kubva pamusoro pemhangura. Iyo PCB inozonyudzwa mune electroless nickel plating yekugezera, uko kemikari reaction inoisa nickel layer pamatehwe emhangura uye mapadhi. Mushure mekunge nickel yaiswa, simbura uye chenesa PCB zvakare kubvisa chero makemikari asara. Chekupedzisira, iyo PCB inonyudzwa mubhavhu regoridhe uye chitete chegoridhe chinoputirwa pamusoro penickel kuburikidza nekusimuka kwekuita. Ukobvu hweiyo goridhe layer inogona kusiyana zvichienderana neiyo chaiyo application uye zvinodiwa. ENIG PCB inopa akawanda mabhenefiti pamusoro pemamwe marapirwo epamusoro. Imwe yemabhenefiti makuru ndeye flat uye yunifomu nzvimbo, iyo inovimbisa yakanakisa solderability uye inoita kuti ive yakakodzera kune Surface Mount Technology (SMT) magungano maitiro. Nzvimbo dzegoridhe dzinodzivirira zvakanyanya kuoxidation, zvichibatsira kuchengetedza hukama hwemagetsi hwakavimbika nekufamba kwenguva.
Imwe bhenefiti yeENIG PCBs kugona kupa yakagadzikana uye inowirirana solder majoini.Iyo yakatsetseka uye yakatsetseka pamusoro peiyo goridhe layer inosimudzira kunyorova uye kunamatira panguva yekushambadzira, zvichikonzera yakasimba uye yakavimbika solder joint.
ENIG PCBs dzinozivikanwawo nepamusoro pekuita kwemagetsi uye kutendeseka kwechiratidzo.Iyo nickel layer inoshanda sechivharo, ichidzivirira mhangura kuti isapararire mudura regoridhe uye kuchengetedza magetsi edunhu. Kune rimwe divi, iyo goridhe layer ine yakaderera yekubata kuramba uye yakanakisa magetsi conductivity, kuve nechokwadi chekuvimbika chiratidzo chekufambisa.
2.Benefits yeENIG PCB
Pano isu tinoongorora mabhenefiti e ENIG PCBs akadai sepamusoro solderability, kusimba, corrosion resistance uye magetsi conductivity. Aya mabhenefiti anoita kuti ENIG PCB ikwane kune dzakasiyana siyana dzekushandisa
ENIG PCB kana Electroless Nickel Immersion Goridhe PCB inopa zvakati wandei zvakanakira pamusoro pemamwe marapirwo epamusoro, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa muindasitiri yezvemagetsi. Ngationgororei zvimwe zvezvakanakira izvi zvakadzama.
