PCB gulu ngalande njira ndi ulamuliro yabwino | YONGMINGSHENG

Kodi mukudziwa zimene ntchito ya PCB gulu  ngalande njira ndi chiyani? Cholinga cha ulamuliro wa njira PCB plating ndi kusunga zigawo mankhwala onse mkati osiyanasiyana mwachindunji ndi ndondomeko. The mankhwala ndi thupi katundu wa ❖ kuyanika ndi anaonetsetsa kokha mwa magawo zafotokozeredwa ndondomekoyi. Pali mitundu yambiri ya njira ntchito ulamuliro, kuphatikizapo mankhwala fractionation, kuyezetsa thupi, asidi mtengo mtima njira, yokoka yeniyeni yothetsera kapena mtima colorimetric. Pasukuluyi tinapangidwa kuonetsetsa olondola, kugwirizana ndi mtendere wa magawo kusamba. Kusankha njira kulamulira anatsimikiza ndi mtundu wa buildup.

Ngakhale njira mawunikidwe ndi odalirika ulamuliro kusamba, palibe chitsimikizo kuti ❖ kuyanika zabwino zopezera. Choncho ndi kofunika amachita mayesero electroplating. Makamaka ambiri electroplating osambira kuwonjezera zina organic kusintha kapangidwe ndi ntchito ya ❖ kuyanika pofuna wabwino magetsi ndi makina zimatha ❖ kuyanika. zina izi zili zovuta kugwiritsa ntchito ndi njira mankhwala kusanthula ndi kusanthula ndipo anayerekezera ntchito njira mayeso electroplating, zimene enaake yofunika kulamulira mipweya ya kusamba. amazilamulira zina monga mtima wa milingo zowonjezera ndi kusintha, kusefera ndi kuyeretsedwa. Muyenera kukhala mosamala "anati" kuchokera Holstein plating kusamba mayeso gulu, ndiyeno bwinobwino kusanthula ndi anaganiza ku chikhalidwe mbale ❖ kuyanika yogawa kukwaniritsa patsogolo kapena patsogolo ndondomeko. Gawo cholinga.

Mwachitsanzo, magawo a dispersibility mkulu, wowala asidi mkulu ndi otsika mkuwa plating kusamba ndi kusintha mwa njira mankhwala kungomanga; kuwonjezera pa kusanthula mankhwala, mankhwala njira mkuwa ndi anaikanso kuti phindu pH asidi kapena chiŵerengero ndi Mtundu muyeso, etc. Ngati mipweya uli mkati ndondomeko zosiyanasiyana pambuyo kusanthula m'pofunika kulabadira kwambiri kusintha magawo ena ndi pamwamba boma la gawo lapansi kuti yokutidwa, monga kutentha kwa njira plating, osalimba panopa, njira ogwiritsa ndi mphamvu ya pamwamba chithandizo boma la gawo lapansi pa kusamba. Makamaka, m'pofunika kulamulira zochita kupanga wodetsedwa-nthaka ya yowala asidi mkuwa plating njira, imene kuposa kololeka ndondomeko mfundo mtengo, ndipo likukhudza pamwamba boma la wosanjikiza mkuwa; malata-kutsogolera aloyi kusamba njira ayenera mosamalitsa kulamulira zili zosafunika mkuwa, monga kuchuluka zidzakhudza wettability ndi weldability ndi chitetezo cha malata-kutsogolera aloyi ❖ kuyanika.

Choyamba, PCB plating mayeso

Ulamuliro mfundo za plating kusamba pazikhalanso waukulu mipweya ya kusamba. Kukwaniritsa chiweruzo zolondola, patsogolo ndi odalirika zida mayeso ndi njira mawunikidwe zifunika. Ena osambira amafunika kugwiritsa ntchito njira wothandiza monga kuyeza yokoka awo enieni ndi phindu asidi (pH). Kuti mwachindunji kusunga pamwamba boma la ❖ kuyanika, ambiri PCB opanga tsopano kutengera njira Holstein ndi poyambira mayeso. The yeniyeni mayeso ndondomeko ndi ingapendame ndi gulu mayeso ndi 37 ° kuti yofanana kutalika mbali yaitali, ndi anode perpendicular limodzi mbali yaitali. Kusintha anode ndi cathode mtunda adzakhala n'zotsimikizira zonse pamodzi cathode, ndi chifukwa kuti panopa pamodzi mbale mayeso zikusintha. Ku chikhalidwe cha kufalitsidwa watsopano wa mbale mayeso, n'zotheka mwasayansi kuona ngati osalimba panopa ntchito plating kusamba ali mkati osiyanasiyana mwachindunji ndi ndondomeko. Zotsatira mwachindunji kwa zowonjezera zili pa kachulukidwe panopa ndi mmene luso pamwamba ❖ kuyanika Angagwiritsidwenso anati.

Chachiwiri, PCB kupinda mayeso njira zoipa:

njira izi anatengera chifukwa masks osiyanasiyana, imene imasonyeza makona, ndi pamalo ake chapamwamba ndipo m'munsi ndinazolowera zotsatira dielectric chifukwa mawonekedwe a choimirira. Izi osiyanasiyana panopa ndi luso zimasweka akhoza kuyesedwa.

Chachitatu, chiweruzo ndi kumasulira:

Kudzera tatchulawa njira mayeso, n'zotheka kuti uweruze chodabwitsa yatsoka mu otsika dera watsopano wa mbale mayeso pa nthawi ya plating ndi kujambula chenichenicho cha mbale mayeso, ndipo akhoza adzaweruzidwa kuti zowonjezera ali wofunikila kuwonjezera; ndi mkulu panopa dera, ndi plating imagwiridwa. Zopindika monga pamwamba akhakula, blackening ndi maonekedwe osasamba kumachitika, zomwe zikusonyeza kuti mupezeke zosafunika zochita kupanga zitsulo mu kusamba likukhudza pamwamba boma la ❖ kuyanika. Ngati pamwamba pa ❖ kuyanika ndi zinamenyanitsa, zikutanthauza kuti mavuto padziko ndi kuchepetsedwa. Zowonongeka plating wosanjikiza zambiri akusonyeza yambiri zina ndi kuwonongeka mu kusamba. zochitika zimasonyeza bwinobwino kufunika kwa kusanthula yake ndi kusintha kuti mipweya ya kusamba likukwaniritsa ndondomeko magawo zafotokozeredwa ndondomekoyi. Owonjezera zowonjezera ndi linakwiriridwa organic amafunika chithandizo, osasankhidwa ndi kuyeretsedwa ntchito adamulowetsa mpweya kapena ngati.

Mwachidule, ngakhale ntchito makompyuta kuti basi kulamulira mmodzi ndi mmodzi mwa chitukuko cha sayansi, koma nayenso ayenera kuyesedwa mwa thandizo, polinga kuti apindule inshuwalansi awiri. Choncho, ambiri ntchito kulamulira njira m'mbuyomu ayenera kugwiritsidwa ntchito kapena mudziwe zambiri ndi chitukuko cha njira mayeso latsopano ndi zida kuti PCB plating ndi ❖ kuyanika ndondomeko changwiro choposa.
