Kuletsa mabowo popanga ndi kuwotcha kumaphatikizapo kuyesa kupanga zatsopano ndikuwunika zotsatira zake. Kudula ndi kuwotcherera ma voti nthawi zambiri kumayambitsa zoyambitsa, monga mtundu wa stateri kapena kubowola kogwiritsidwa ntchito popanga. Opanga PCB amatha kugwiritsa ntchito njira zingapo zazikulu kuti muzindikire ndikuthana ndi zomwe zimayambitsa matendawa.

1.Kobwen Ref Full Spend

Njira imodzi yopewera mipata yowuma ndikusintha dera lovuta la Reflux Curve. Kupereka magawo osiyanasiyana a nthawi kumatha kuwonjezera kapena kutsika mwayi wa kupanga mafomu. Kuzindikira mikhalidwe yabwino yobwereketsa ndikofunikira kuti pakhale kopepuka kopambana.

Choyamba, onani zosintha zomwe zilipo kuti zitheke. Yesani kukulitsa kutentha kosatsatsa kapena kukulitsa nthawi yotsatsa kwa curlux. Mabowo a msirikali amatha kupanga chifukwa chosakwanira kutentha m'malo otsogola, choncho gwiritsani ntchito njira izi kuthana ndi zomwe zidayambitsa.

Mabwalo oyendetsa kutentha amakhalanso odziwika bwino kwambiri m'malo owala. Nthawi yochepa kwambiri imatha kulola zigawo zonse ndi madera a bolodi kuti akwaniritse kutentha. Yesani kulola nthawi yowonjezera ya malo awa a Reflux Curve.

2.Pambala pang'ono

Kuchulukitsa kwambiri kumatha kukulitsa ndipo nthawi zambiri kumabweretsa kuwotcherera. Vuto lina lolumikizana ndi zolumikizira: flux spenas. Ngati flux ilibe nthawi yokwanira ku depess, gasi wowonjezera idzakodwa komanso opanda kanthu idzapangidwa.

Pamene flux yochulukirapo imagwiritsidwa ntchito pa PCB, nthawi yomwe imafunikira kuti flux ilembetsedwetu. Pokhapokha mutawonjezera nthawi yowonjezera, yowonjezera yowonjezera imabweretsa ma wevel.

Powonjezera nthawi yocheperako imatha kuthana ndi vutoli, limathandizanso kumamatira kuchuluka kwa chimfine. Izi zimasunga mphamvu ndi zothandizira ndikupanga zotsuka zoyeretsa.

3. Amangokhala mabatani othamanga okha

Zomwe zimafala kwambiri popanga mabowo ndizosautsa. Blati kapena kuwongolera kosavomerezeka kumatha kuwonjezera mwayi wa zinyalala za zinyalala pobowola. Zidutswa izi zikamamatira pa PCB, amapanga madera opanda kanthu omwe sangakhale ndi mkuwa. Izi zimasuntha kuti kuchititsa chidwi, mtundu komanso kudalirika.

Opanga amatha kuthana ndi vutoli pogwiritsa ntchito mabavu akuthwa komanso akuthwa. Khazikitsani dongosolo losasinthasintha kuti lizithamangitsa kapena kusintha mabatani, monga kotala. Kukonza pafupipafupi kumatsimikizira kusagwirizana ndi dzenje ndikuchepetsa kuthekera kwa zinyalala.

4.Tra template yosiyanasiyana

Kapangidwe ka template yomwe imagwiritsidwa ntchito posankha kungathandize kapena kulepheretsa kupewa. Tsoka ilo, palibe kukula-kokwanira - njira yonse yothetsera kuyesa kusankha. Mapangidwe ena amagwira bwino ntchito ndi walonda wosiyanasiyana, flux, kapena mtundu wa PCB. Zitha kutenga mayesero ndi cholakwika kupeza chisankho kwa mtundu wina wa bolodi.

Kupeza bwino kapangidwe ka template kumanja kumafuna kuyesa bwino. Opanga ayenera kupeza njira yoyezera ndi kusanthula zotsatira za kapangidwe kazinthu.

Njira yodalirika yochitira izi ndikupanga gulu la ma PCB yokhala ndi ma template ena ndikuwayang'ana bwino. Ma tempulo angapo osiyanasiyana amagwiritsidwa ntchito pochita izi. Kuyendera kuyenera kuwulula zomwe forticess zopanga zimakhala ndi mabowo ambiri ankhondo.

Chida chachikulu pakuwunika ndi makina a X-ray. X-ray ndi imodzi mwanjira zopezera voids yopepuka ndipo ndizothandiza kwambiri mukamachita ndi ma pcbs ochepa. Kukhala ndi makina osavuta a X-ray kumapangitsa kuyenderako kovuta komanso kovuta.

5. Kubowoleza

Kuphatikiza pa lakuthwa pang'ono, kuthamanga kwabowo kumathandizanso kwambiri pa ntchito. Ngati kuthamanga pang'ono kuli kwakukulu, kumachepetsa kulondola ndikuwonjezera mwayi wa zinyalala. Kuthamanga kwambiri kumatha kukuwonjezera chiopsezo cha kuwonongeka kwa PCB, kuopseza umphumphu.

Ngati mabowo okutidwa ndi zojambulazo akadali ofala mutatha kufalitsa kapena kusintha pang'ono, yesani kuchepetsa kukwera. Kuthamanga pang'onopang'ono kumapatsa mwayi wopanga, kuyeretsa kudzera mabowo.

Kumbukirani kuti njira zachikhalidwe zachikhalidwe si kusankha lero. Ngati mukuchita bwino ndikuganizira kuti mukuyendetsa mitengo yobowola kwambiri, kusindikiza kwa 3 kungakhale chisankho chabwino. 3D ma PCBS osindikizidwa a 3D amapangidwa moyenera kwambiri kuposa njira zachikhalidwe, koma ndi zolondola kapena zapamwamba kapena zapamwamba. Kusankha PCB ya 3D sikungafunikire kubowola kudzera mabowo konse.

6.Sick to Hight High Stute Watte

Mwachibadwa kufunafuna njira zosungira ndalama mu njira yopanga PCB. Tsoka ilo, kugula yotsika mtengo kapena yotsika mtengo imatha kuwonjezera mwayi wopanga ma welve.

Mankhwala osiyanasiyana a staterider mitundu yosiyanasiyana amakhudza momwe amagwirira ntchito ndi momwe amagwirizanitsa ndi PCB panthawi yokonzanso. Mwachitsanzo, kugwiritsa ntchito msile phala lomwe lilibe chitsogozo cha nthawi yozizira.

Kusankha wosuta wamtali wa asitikali amafuna kuti mumvetsetse zosowa za PCB ndi templala yomwe imagwiritsidwa ntchito. Phati la sthicker limakhala lovuta kulowa template yokhala ndi mawonekedwe ang'onoang'ono.

Zitha kukhala zothandiza kuyesa masitayilo osiyanasiyana nthawi yomweyo monga kuyesa ma tempulo osiyanasiyana. Kutsindika kumayikidwa pogwiritsa ntchito lamulo lapamtunda kuti musinthe template kukula kwake kuti msirikali ameze template. Lamuloli likuti kuti opanga azigwiritsa ntchito mawonekedwe ndi zigawo zofunika kuti agwirizane ndi mipira isanu ya asirikali. Lingaliro ili limasambirikiza njira yopangira ma phala osiyanasiyana oyeserera kuti muyese.

7. Wogulitsa asitikali attekidation

Oxidation wa wogulitsa nthawi zambiri amapezeka pomwe pali mpweya wambiri kapena chinyezi pazopanga. Maxidation pawokha imawonjezera mwayi wokhala ndi voids akupanga, ndipo zimatinso kuti mpweya kapena chinyezi zimawonjezera chiopsezo chazomwe zimawonongeka. Kuthetsa maxidation kumathandiza kupewa kusintha ndikusintha mtundu wa PCB.

Choyamba onani mtundu wa stateri wa starder omwe amagwiritsidwa ntchito. Wogulitsa madzi wosungunuka amasuta makamaka makamaka oxidation. Kuphatikiza apo, kusakwanira flax kumawonjezera chiopsezo cha oxidation. Zachidziwikire, mochulukitsa kwambiri ndi vuto, kotero opanga ayenera kupeza bwino. Komabe, ngati makuti oxidation amachitika, ndikuwonjezera kuchuluka kwa flux kumatha kuthana ndi vutoli.

Opanga PCB amatha kuchitapo kanthu zambiri popewa kupanga mabowo ndi kuwotzera mabowo pazinthu zamagetsi. Ma voids amakhudza kudalirika, magwiridwe antchito ndi mtundu. Mwamwayi, kuchepetsa mwayi wokhala ndi voids akupanga ndikosavuta monga kusintha kwa msirikali phala kapena pogwiritsa ntchito njira yatsopano.

Pogwiritsa ntchito njira yopenda mayeso, wopanga aliyense amatha kupeza ndikuthana ndi zomwe zimayambitsa voluluk mu Reflux ndikuyika njira.
