Etching peroxide gulu hydrogen ndi citric acid: processing mitengo subtleties

Etching gulu hydrogen peroxide ndi citric asidi - Chinsinsi makamaka wotchuka ndi wailesi ankachita masewera. Izo si kudya, komanso njira otetezeka kukonzekera zinthu soldering za tsogolo chida lona.

Kodi gulu tikuona m'mbuyomu?

Poyamba, kuti kusindikizidwa dera bolodi, kunafuna kwambiri khama. wadera woyamba ayipanga pa pepala, ndiye nkhonya osalembapo ndipo ndipo umasamutsidwa ku mayendedwe pa PCB kapena zojambulazo getinaks, ntchito utoto mankhwala. Pambuyo kuyanika anang'amba kuchokera ❖ kuyanika ake, ndi gulu anamizidwa mu chidebe kwa etching dambo.

Chinthu chovuta kwambiri chinali amalipiritsa poizoni. Popeza Mwaichi pamaziko a tchire ntchito mankhwala enaake ferric. Wailesi sukulu njira imeneyi sanali zikusowa, koma pano kunyumba anali kufunafuna njira ina, monga ambiri Nthawi zambiri bluestone.

bolodi processing anatenga izo chinsinsi china: bolodi anali unazokotedwa omangidwa. Ena mayendedwe umachititsa, ndi m'madera ena nedotravlivalas pamwamba. Onse chifukwa cha osadziwa amisiri kapena reusable Luzhny njira.

njira zamakono za matabwa processing

Etching peroxide gulu hydrogen ndi citric acid si zachilendo. Ambiri amva za njira izi kale. Ndi kusankha mwina gulu maphunziro, mupeza palibe phindu poyerekeza ndi etching mu mankhwala enaake ferric. Mwachitsanzo, processing quality, chitetezo ndi peroxide zachilengedwe limodzi ndi oxidant ndi.

Chinsinsi nyumba khadi processing

Zonse zofunika kuti agwire etching wa gulu la hydrogen peroxide ndi citric acid, angapezeke mu mankhwala ake nduna ndi kukhitchini, kapena kugula popanda vuto. Wina osiyana mwayi processing matabwa m'njira - mtengo wa zosakaniza kuti akonze njira. Ndi mwayi wina wa osakaniza wa hydrogen - zidzakhala mtengo kwambiri ferric mankhwala enaake.

chigawo zikuchokera

• Wa hydrogen peroxide 3% TH - 100 ml.
• Citric asidi - magalamu 30.
• Sodium kolorayidi - magalamu 5 (monga wothandiza chigawo zotani).
• Madzi (ngati n'koyenera).

Zofunika! Yankho anakonza mu magawo oterowo zokwanira etch mkuwa zojambulazo a makulidwe 35 microns ndi malo a 100 sq. cm.

kukonzekera bolodi

1. Jambulani ndi mtengo kulisindikiza.
2. Dulani chofunika kukula chidutswa cha PCB.
3. Kusamutsa tona pa PCB ndi tiyeni zilowerere, ndiye kuchotsa.

Kodi kukonzekera yankho?

1. Preheat hydrogen peroxide: kuika botolo mu madzi osamba ndi kudikira mpaka kutentha kwa zinthu ziwiri limagwirizana.
2. Tengani kapu. Iliyonse yabwino, koma osati zitsulo.
3. Thirani peroxide preheated ndi mwaukhondo ndi youma mphika vsypte citric acid.
4. Sakanizani bwino.
5. Pamene oyambitsa, kuwonjezera mchere, amene amachita monga njira chothandizira.

Kodi etch bolodi?

Kuti etch ndi peroxide gulu hydrogen ndi citric acid kutha mungagwiritse ntchito muli awiri. Kunena mwachidule ang'onoang'ono mphamvu dambo mu chidebe zazikulu ndi kutsanulira madzi otentha mu izo. Izi kufulumizitsa ndi patsogolo ndondomeko.

Etching bolodi mu tsa-D hydrogen peroxide imagwiridwa motere: kuyang'anira anaikidwa mbali dambo amene mayendedwe pafupi pansi mankhwala oipa mosavuta adatchithisira pansi chidebe. Kuti zimene anali yunifolomu kwambiri njira ayenera kukhala nthawi kusonkhezera pang'ono. Dongosolo lonse amatenga Pasanathe mphindi 10.

Akamaliza mlandu chamba adzafooledwa ndi rinsed pansi madzi.

Njira imeneyi malipiro kwathunthu chithandizo otetezeka. Pangani malipiro wotheka kuntchito, kunyumba ndi ofesi ndi ntchito ndi reagents osadziteteza pa nthawi yomweyo Sikuti.

Zofunika! Ngati yankho thovu kwambiri, mchere inu thrashed kwambiri. Meanly zambiri peroxide, mwinamwake zimene zidzachitike pa njira yogwira akhoza kuonongeka.

Ngati zimene inu kukokera bolodi ndi kuyang'ana pa izo, inu simutha kuzindikira kusiyana, poyerekeza ndi mmene kusindikizidwa dera bolodi etching mu mankhwala enaake ferric, amangoika satero. Chachikulu kusiyana - mwamsanga kudutsa anachita ndi ndondomeko zochepa oopsa kwa anthu.

Kodi mukudziwa kuti gulu kale unazokotedwa?

Sing'anga wa hydrogen-acidic anachita atuluka malinga ndi njira: Cu + H3Cit + H2O2 → H [CuCit] + 2H2O. Etching wa PCB mu hydrogen peroxide tinganene kuti wathunthu pamene anaima anachita aliyense mu njira: izo salinso fizzing kapena kuonekeratu.

Bolodi yomalizidwa lidzayeretsedwa ndi osambitsidwa ndi madzi. Tona kapena inki wosambitsa ndi kafungo kabwino. Ndiye mosamala misozi bolodi ndi degreased.

Zofunika! Fufuzani umphumphu wa njanji pa bolodi pambuyo mankhwala. Kuonongeka dera sizigwira ntchito.

Monga mukuonera, etching gulu hydrogen peroxide mu kunyumba si zotheka, komanso otetezeka. Sizovuta kupeza zosakaniza zofunika kukonzeketsera zikuchokera etching, ndi ndondomeko amatenga Pasanathe mphindi 15. Lero, munthu aliyense ankachita masewera wailesi, chifukwa cha malangizo losavuta komanso ndi lolondola ndipo akhoza kuyetsa kunyumba popanda vuto iwowo ndiponso anthu ena.
