Etching hukumar hydrogen peroxide da kuma citric acid: sarrafa kudade tausasãwa

Etching hukumar hydrogen peroxide da kuma citric acid - girke-girke ne musamman rare tare da mai son rediyo. Shi ne ba kawai azumi, amma kuma da safest hanya don samun shirye domin soldering abubuwa na gaba kayan zane.

Yadda etched jirgin a baya?

A baya can, don yin da buga kewaye hukumar, shi ake bukata mai yawa kokarin. Da farko kewaye bred a kan takarda, sa'an nan a blank naushi sa'an nan canjawa wuri zuwa wažožin a kan PCB, ko tsare getinaks, ta amfani da Paint samfurin. Bayan da bushewa tsãge kashe ta shafi, da kuma jirgin da aka nutsa cikin wani akwati domin etching makiyaya.

A mafi wuya abu ya zuwa guba fee. Tun da wannan manufa a kan tushen daji ta amfani da ferric chloride. A rediyo makaranta wannan hanyar ba wanda bai isa ba, amma a nan a gida ya nemi madadin, kamar yadda aka fi yi bluestone.

kwamitin aiki ɗauka tãre da shi wani asiri: hukumar da aka etched unevenly. Wasu waƙoƙi corrodes, da kuma a wasu wurare da surface nedotravlivalas. All saboda inexperience na sana'a ko reusable Luzhny bayani.

Hanyoyin zamani na aiki allon

By zabi wannan zabin hukumar horo, za ka samu wani alhẽri ba idan aka kwatanta da etching a ferric chloride. Alal misali, aiki quality, lafiya da kuma muhalli peroxide a hade tare da wani oxidant.

Girke-girke katin aiki gidan

Duk abin da ake bukata domin ya yi etching na kwamitin hydrogen peroxide da kuma citric acid, za a iya samu a cikin magani hukuma da kuma a cikin kitchen, ko za su iya saya ba tare da wani matsaloli. Wani jinsin amfani aiki allon a cikin irin wannan hanya - da kudin da sinadaran don ƙirƙirar wani bayani. Wannan wani amfani da hydrogen cakuda - shi zai zama da yawa mai rahusa ferric chloride.

bangaren abun da ke ciki

• Hydrogen peroxide 3% th - 100 ml.
• Citric acid - 30 grams.
• Sodium chloride - 5 grams (as wani karin bangaren na dauki).
• Ruwa (idan ya cancanta).

Muhimmanci! Magani shirya a irin rabbai isa ya etch da jan tsare na kauri 35 microns da kuma wani yanki na 100 sq. cm.

2. Yanke fitar da ake bukata size yanki na PCB.
3. Sauye Toner a kan PCB, kuma bari jiƙa, sa'an nan kuma cire.

Yadda za a shirya wani bayani?

1. Preheat hydrogen peroxide: sa cikin kwalbar a cikin wani ruwa mai wanka da kuma jira har sai da zazzabi na biyu abubuwa ne masu hada kai.
2. Dauki kofin. Kowane dace, amma ba karfe.
3. Zuba peroxide preheated zuwa tsabta da kuma bushe tukunya vsypte citric acid.
4. Mix da kyau.
5. Jujjuyawa, ƙara gishiri, da abubuwa a matsayin mai kara kuzari bayani.

Yadda etch hukumar?

Don etch hukumar hydrogen peroxide da kuma citric acid wuce da sauri, za ka iya amfani da biyu kwantena. Kawai sa karami damar makiyaya a cikin fi girma akwati da kuma zuba ruwan zafi a cikin shi. Wannan zai bugun sama da kuma bunkasa tsari.

Etching hukumar a p-D hydrogen peroxide aka yi kamar haka: cajin sanya shi a cikin wani makiyaya gefe a kan wanda waƙoƙi suna kõma saukar zuwa lalata kayayyakin ana iya saukar da zuwa kasa daga cikin akwati. Don dauki kasance mafi uniform bayani ya zama daga lokaci zuwa lokaci don motsa dan kadan. A dukan tsari daukan kasa da minti 10.

Wannan Hanyar biya ne gaba daya lafiya magani. Make biyan bashin yanzu zai yiwu a yi aiki, a gida da kuma a cikin ofishin da kuma aiki tare da unsafe reagents a lokaci guda ba lallai ba ne.

Muhimmanci! Idan bayani ne sosai kumfa, da gishiri ka lallasa yawa. Meanly mafi peroxide, in ba haka ba da dauki zai faru a kan aiki hanyoyi za su iya lalacewa.

Idan dauki ka ja jirgin, kuma kalle shi, za ka ba lura da wani bambanci, idan aka kwatanta da yadda ta buga kewaye hukumar etching a ferric chloride, su kawai ba. Babban bambancin - sauri wucewa dauki da kuma kasa m tsari ga mutane.

Ta yaya ka san cewa jirgin da aka riga etched?

A hydrogen-acidic matsakaici da dauki fitowa bisa ga dabara: Cu + H3Cit + H2O2 → H [CuCit] + 2H2O. Etching na PCB a hydrogen peroxide za a iya daukan cikakken lokacin tsaya wani dauki a cikin bayani: shi ne ba fizzing ko bubbling.

A ƙãre kwamitin da aka tsarkake da kuma wanke da ruwa. Toner ko tawada wanka tare da acetone. Sa'an nan a hankali goge katako da kuma degreased.

Muhimmanci! Duba mutuncin waƙoƙi a kan jirgin bayan da magani. Lalace kewaye zai yi aiki ba.

Kamar yadda ka gani, etching hukumar hydrogen peroxide a cikin gida ne ba kawai zai yiwu, amma kuma hadari. Ba wuya a sami zama dole sinadaran shirya abun da ke ciki na etching, da kuma aiwatar daukan kasa da minti 15. Yau, kowane rediyo mai son, godiya ga sauƙi, kuma m shawara iya gwaji a gida ba tare da cutar da kansu da sauransu.
