Application

Inonyanya kushandiswa mukurongedza-silver-plated packaging, senge mabhodhi edunhu, maLED, edunhu mabhodhi, hardware zviteshi, zvinyorwa zvekudzivirira chikafu, girazi kurongedza, hardware kurongedza, Stainless simbi kupatsanura ndiro, nezvimwe.

Sei uchida bepa risina sulfur?

Tisati tataura nezvekuti sei sulfur-free paper inoshandiswa, tinoda kutaura pamusoro pechinhu "PCB" (yakadhindwa bhodhi redunhu) inodzivirirwa nesarufa-isina mapepa-PCB kutsigirwa kwezvinhu zvemagetsi uye chimwe chezvinhu zvinokosha mumagetsi. industry.Anenge marudzi ese emidziyo yemagetsi, kubva pawachi dzemagetsi uye macalculator kusvika kumakomputa nemidziyo yekutaurirana, inoda PCB kuti ione kubatanidzwa kwemagetsi pakati pezvikamu zvakasiyana.

Muviri mukuru wePCB imhangura, uye mhangura yemhangura inopindirana nyore neokisijeni mumhepo kuti ibudise yakasviba cuprous oxide.Kuti udzivise oxidation, pane maitiro ekuisa sirivheri mukugadzira PCB, saka PCB board inonziwo sirivheri deposition board.Silver deposition process yave imwe yekupedzisira pamusoro pekurapa nzira dzePCB yakadhindwa.

Sulfur-isina mapepa ekurongedza wedunhu bhodhi, asi kunyangwe kana sirivheri deposition process yakagamuchirwa, haina zvachose isina hurema:

Pane hukama hukuru pakati pesirivha nesarufa.Kana sirivheri ikasangana nehydrogen sulfide gasi kana sulfur ions mumhepo, zviri nyore kugadzira chinhu chinonzi silver sulfide (Ag2S), chinosvibisa bonding pad uye kukanganisa iyo inotevera welding process.Uyezve, sirivheri sulfide yakaoma zvakanyanya kunyungudika, izvo zvinounza kuoma kukuru mukuchenesa.Naizvozvo, mainjiniya akangwara auya nenzira yekuparadzanisa PCB kubva kune sarufa ayoni mumhepo uye kuderedza kusangana pakati pesirivha nesarufa.Ipepa risina sulfur.

Kupfupisa, hazvina kuoma kuwana kuti chinangwa chekushandisa sulfur-isina mapepa ndeaya anotevera:

Chekutanga, iyo sarufa-isina bepa pachayo haina sarufa uye haiite nesirivha deposition layer paPCB.Kushandisa bepa risina sulfuri kuputira PCB kunogona kunyatso kudzikisa kusangana pakati pesirivha nesarufa.

Chechipiri, bepa risina sulfuri rinogonawo kuita basa rekuzviparadzanisa nevamwe, kudzivisa kuita pakati pemhangura yemhangura pasi pesilvha deposition layer uye okisijeni mumhepo.

Muchibatanidzwa chekusarudza mapepa asina sulfuri, pane chaizvoizvo zvinyengeri.Semuenzaniso, bepa risina sulfuri rinoda kusangana neROHS zvinodiwa.Pepa remhando yepamusoro-soro rine sarufa harina sarufa chete, asiwo rinobvisa zvine muchetura zvakaita seklorini, lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers, nezvimwewo, izvo zvinozadzisa zvizere zvinodiwa neEU. mipimo.

Panyaya yekuramba tembiricha, bepa rekushandisa rine midziyo yakakosha yekuramba tembiricha yepamusoro (inenge 180 madhigirii Celsius), uye iyo pH kukosha kwepepa haina kwayakarerekera, iyo inogona kudzivirira zvirinani PCB zvinhu kubva kune oxidation uye yero.

Pakurongedza nemapepa asina sarufa, isu tinofanirwa kutarisisa kune rumwe ruzivo, kureva kuti, iyo PCB board ine sirivheri-yakanyudzwa tekinoroji inofanira kuiswa mukati pakarepo mushure mekugadzirwa, kuitira kuderedza nguva yekubatana pakati pechigadzirwa nemhepo.Pamusoro pezvo, pakurongedza bhodhi rePCB, magirovhosi asina sarufa anofanirwa kupfekwa uye haafanire kubata nzvimbo ine electroplated.

Nekuwedzera kuri kudiwa kwePCB isina lead-isina muEurope neAmerica, PCB ine sirivheri netin deposition tekinoroji yave iyo huru pamusika, uye bepa risina sarufa rinogona kuvimbisa zvizere kunaka kwesirivha kana tin deposition PCB.Semhando yepepa rakasvibirira maindasitiri, bepa risina sulfur richawedzera kufarirwa pamusika, uye ive iyo yekurongedza chiyero chePCB muindasitiri.

Zvikonzero zvekushandisa bepa risina sulfur.

Iwe unofanirwa kupfeka magirovhosi asina sulfuri kana uchibata bhodhi-yakaputirwa bhodhi.Sirivha ndiro inofanira kupatsanurwa kubva kune zvimwe zvinhu nepepa risina sarufa panguva yekuongorora nekubata.Zvinotora maawa masere kupedzisa sirivheri kunyura bhodhi kubva panguva yekubuda mutsetse wesirivha wekunyura kusvika panguva yekurongedza.Pakurongedza, bhodhi resirivha rinofanirwa kupatsanurwa kubva pabhegi rekurongedza nepepa risina sarufa.

Pane hukama hukuru pakati pesirivha nesarufa.Kana sirivheri ikasangana nehydrogen sulfide gasi kana maion esarufa mumhepo, zviri nyore kuumba yakanyanyisa kunyungudika sirivheri munyu (Ag2S) (sirivha munyu ndicho chinhu chikuru che argentite).Kuchinja kwekemikari uku kunogona kuitika mune zvishoma.Nekuti sirivheri sulfide ipfumbu-dema, nekuwedzera kwekuita, sirivheri sulfide inowedzera nekukora, uye ruvara rwepamusoro pesirivheri zvishoma nezvishoma rwunoshanduka kubva kuchena kuenda kune yero kuenda kune grey kana dema.

Musiyano pakati pepepa risina sulfur uye mapepa akajairika.

Pepa rinowanzoshandiswa muhupenyu hwedu hwezuva nezuva, kunyanya mazuva ese pataive vadzidzi.Pepa ipepa rakatetepa rakagadzirwa nemuti fiber, iyo inoshandiswa zvakanyanya.Pepa rinoshandiswa muminda dzakasiyana rakasiyana, senge pepa reindasitiri uye pepa reimba.Pepa remaindasitiri senge bepa rekudhinda, bepa risina sarufa, pepa rinonyura mafuta, pepa rekuputira, kraft bepa, guruva-rinodzivirira guruva, nezvimwewo, uye mapepa epamba akadai semabhuku, napkins, mapepanhau, chimbuzi, nezvimwewo. ngatitsanangurirei mutsauko pakati pemaindasitiri asina sarufa bepa nemapepa akajairika.

Pepa risina sulfur

Sulfur-isina bepa ndeye yakakosha padding bepa rinoshandiswa muPCB silvering process mune redunhu bhodhi vanogadzira kudzivirira kemikari kuita pakati pesirivheri nesarufa mumhepo.Basa rayo nderekuisa sirivha nemakemikari uye kudzivirira kuita kwemakemikari pakati pesirivha nesarufa mumhepo, zvichikonzera kutsvuka.Pasina sarufa, inogona kudzivirira kukanganisa kunokonzerwa nekuita pakati pesarufa nesirivha.

Panguva imwecheteyo, bepa risina sulfuri rinodzivirirawo kuita kwemakemikari pakati pesirivheri mu electroplated chigadzirwa uye sarufa mumhepo, zvichiita kuti chigadzirwa chive yero.Nokudaro, kana chigadzirwa chapera, chigadzirwa chacho chinofanira kuiswa nepepa risina sulfuri nokukurumidza sezvinobvira, uye magirovhosi asina sulfuri anofanira kupfekwa paunosangana nechigadzirwa, uye electroplated surface haifaniri kubatwa.

Hunhu hwemapepa asina sarufa: bepa risina sulfuri rakachena, risina guruva uye risina chip, rinosangana neROHS zvinodiwa, uye harina sulfur (S), chlorine (CL), lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (CrVI), polybrominated biphenyls uye polybrominated diphenyl ethers.Uye inogona kuiswa zvirinani kuPCB redunhu bhodhi remagetsi indasitiri uye hardware electroplating indasitiri.

Musiyano pakati pepepa risina sulfur uye mapepa akajairika.

1. Sulfur-isina bepa inogona kudzivirira kemikari kuita pakati pesirivha mune electroplated zvigadzirwa uye sarufa mumhepo.Bepa rakajairwa harina kukodzera pepa re electroplating nekuda kwetsvina yakawandisa.
2. Sulfure-isina bepa anogona zvinobudirira kurambidza kemikari kuita pakati sirivheri mu pcb uye sarufa mumhepo kana rinoshandiswa pcb indasitiri.
3. Sulfur-isina bepa anogona kudzivirira huruva uye machipisi, uye tsvina pamusoro penyika electroplating indasitiri kuchakanganisa electroplating mugumisiro, uye tsvina iri pcb redunhu zvingakanganisa connectivity.

Mapepa akajairika anonyanya kugadzirwa neshinda dzezvirimwa, sehuni nehuswa.Izvo zvigadzirwa zvemapepa asina sarufa hazvisi zvekudyara chete, asiwo zvisiri zvezvirimwa fiber, senge synthetic fibers, kabhoni fibers uye simbi fibers, kuitira kubvisa sulfur, chlorine, lead, cadmium, mercury, hexavalent chromium, polybrominated. biphenyls uye polybrominated diphenyl ethers kubva papepa.Kuti ugadzirise zvimwe zvikanganiso zvebepa rekutanga, zvinobatsira kuvandudza kunaka kwepepa uye kuzadzisa chinangwa chekugadzirisa musanganiswa.
