Njira Zogulitsira za PCB yokhala ndi mbali ziwiri

Makhalidwe a bolodi lozungulira mbali ziwiri

Single-mbalimbali dera bolodi ndi iwiri mbali bwalo dera mu kusiyana ndi chiwerengero cha zigawo zamkuwa ndi osiyana.Awiri-mbalimbali dera bolodi ndi bolodi pa mbali zonse za mkuwa, akhoza kudzera dzenje kuchita kulumikiza udindo.Mbali imodzi yokha ya mkuwa, imatha kupanga mzere wosavuta, dzenje lopangidwa lingagwiritsidwe ntchito pa plug-in silingakhale conduction.

The luso amafuna awiri mbali bolodi dera ndi kachulukidwe mawaya amakhala lalikulu, ang'onoang'ono dzenje m'mimba mwake, zitsulo dzenje m'mimba mwake amakhalanso ang'onoang'ono.Wosanjikiza ndi wosanjikiza interconnection zimadalira dzenje metallization, khalidwe mwachindunji zokhudzana ndi kudalirika kwa bolodi kusindikizidwa dera.

Ndi kuchepetsa kabowo, choyambirira kwa kabowo lalikulu silinakhudze zinyalala, monga akupera zinyalala, phulusa chiphala, kamodzi otsala mu dzenje laling'ono mkati, adzapanga mankhwala mpweya mkuwa, mkuwa plating kutaya zotsatira, dzenje. popanda mkuwa, kukhala dzenje metallization wa wakupha wakupha.

Njira yowotcherera ya board ya mbali ziwiri

Awiri am'mbali mbali bwalo gulu kuti kuonetsetsa kuti mbali ziwiri dera ndi odalirika conductive zotsatira, tikukulimbikitsani kuti choyamba mugwiritse ntchito mawaya ndi kuti kuwotcherera dzenje kugwirizana pa mbali ziwiri mbali (ie, ndondomeko metalization kudzera dzenje gawo), ndi kudula nsonga kugwirizana mzere wotuluka mbali, kuti asabaya dzanja woyendetsa, umene ndi bolodi kugwirizana kukonzekera ntchito.

Zofunikira zapawiri-mbali zowotcherera board

1. Pali zofunikira pakupanga chipangizocho chiyenera kukhala mogwirizana ndi zofunikira za zojambula za ndondomekoyi;ndiko kuti, kupanga koyamba pambuyo pa pulagi.

2. mutatha kupanga gawo lachitsanzo la diode liyenera kuyang'ana mmwamba, pasakhale kusagwirizana kwa kutalika kwa zikhomo ziwirizo.

3. chipangizo ndi zofunika polarity pamene anaikapo kulabadira polarity ake sadzakhala anaikapo n'zosiyana, mpukutu Integrated chipika zigawo zikuluzikulu, pambuyo kulowetsa, kaya ofukula kapena kunama chipangizo, sipadzakhala mapendekedwe zoonekeratu.

4. Soldering chitsulo mphamvu 25 mpaka 40W, soldering chitsulo mutu kutentha ayenera kulamulidwa pafupifupi 242 ℃, kutentha ndi mkulu kwambiri mutu mosavuta "wakufa", kutentha ndi otsika sangathe kusungunula solder, soldering nthawi kulamulira mu 3 mpaka 4. masekondi.

5.Reflow uvuni or makina opangira ma wave solderingkuwotcherera ofunda ndi zambiri malinga ndi chipangizo kuchokera lalifupi mpaka mkulu, kuchokera mkati mpaka kunja kwa mfundo kuwotcherera ntchito, kuwotcherera nthawi mbuye, motalika adzawotcha chipangizo, adzawotcha mizere mkuwa atavala pa nsalu zamkuwa. bolodi.

6. Chifukwa ndi kuwotcherera mbali ziwiri, kotero ayeneranso kuchita ndondomeko yoyika chimango cha bolodi la dera ndi zina zotero, cholinga sichikukakamiza oblique pansi pa chipangizocho.

7. akamaliza dera bolodi soldering ayenera mabuku cheke pa chiwerengero cha mtundu, fufuzani malo pamene pali kutayikira kulowetsa ndi kutayikira kwa kuwotcherera, kutsimikizira dera bolodi redundant zipangizo monga pini yokonza, pambuyo kuyenderera munjira ina.

8, mu ntchito yeniyeni, ayeneranso kutsatira mosamalitsa mfundo ndondomeko ntchito kuonetsetsa khalidwe kuwotcherera mankhwala.

Ndi chitukuko chofulumira cha zamakono, ndi ubale wapamtima wa anthu ndi zinthu zamagetsi mu kukonzanso kosalekeza, anthu amafunikiranso ntchito zapamwamba, kukula kwazing'ono, zinthu zambiri zamagetsi zamagetsi, zomwe zimapereka zofunikira zatsopano za gulu ladera.

Awiri-mbali mbali gulu dera Choncho anabadwa, chifukwa chafala ntchito yawiri-mbali mbali dera bolodi, zikuchititsa kusindikizidwa dera bolodi kupanga komanso kuwala, woonda, lalifupi, chitukuko yaing'ono.
