Mabwalo ozungulira a PCB amagwiritsidwa ntchito kwambiri pazogulitsa zamagetsi zamagetsi zotukuka zamakono. Malinga ndi mafakitale osiyanasiyana, utoto, mawonekedwe, kukula, wosanjikiza, ndi zinthu za matabwa a PCB ndi osiyana. Chifukwa chake, chidziwitso chowonekera chimafunikira mu kapangidwe ka ma boani ozungulira a PCB, popanda kusamvana komwe kumachitika kuti zichitike. Nkhaniyi ifotokoza mwachidule zolakwika khumi zochokera ku mavuto omwe amapanga ma boani a PCB.

1. Kutanthauzira kwa mawonekedwe osamveka sikumveka

Gulu la mbali imodzi limapangidwa pamtunda wapamwamba. Ngati palibe malangizo omwe mungachite kutsogolo ndi kumbuyo, zingakhale zovuta kugulitsira board ndi zida.

2. Mtunda pakati pa malo akuluakulu amkuwa ndi chimango chakunja chayandikira kwambiri

Mtunda pakati pa zokongoletsera zamkuwa zamkuntho ndi chimango chakunja chiyenera kukhala osachepera 0,2mm, chifukwa nthawi yomwe imang'ambika, ngati itasinthidwa pa zojambulazo zamkuwa kuti zitheke.

3. Gwiritsani ntchito mabatani kuti mujambule mapepala

Zojambula zojambula ndi mabodi a mafayilo zimatha kudutsa drc poyang'ana mabwalo, koma osati pokonza. Chifukwa chake, ma pads oterewa sangathe kupanga mwachindunji deta yankhondo. Mkazi akana kukana amagwiritsidwa ntchito, malo a chipika cha filler chidzakutidwa ndi msirikali kukana, kupangitsa kuti kuthyoledwe ndi chipangizocho ndikovuta.

Chifukwa imapangidwa ngati magetsi mu mawonekedwe a mapiritsi, nthaka yotsekedwa ili pafupi ndi chithunzicho pa bolodi lenileni, ndipo malumikizo onse ndi mizere yotalikirana. Samalani mukamajambula mapangidwe angapo a magetsi kapena mizere ingapo yodzipatula, ndipo musasiye mipata iwiri kuti ipangitse magulu awiri a magetsi kuti ayambitse malo olumikizira kuti aletse.

5. Olemba Olakwika

Matumba a SMD a chivundikiro cha mapiritsi amabweretsa zosokoneza ku mayeso a pa board ndi kuwotcherera. Ngati mawonekedwe a mawonekedwewo ndi ochepa kwambiri, imapangitsa kusindikiza payekha kukhala kovuta, ndipo ngati kuli kokulirapo, otchulidwawo azidzaza wina ndi mnzake, zimapangitsa kukhala kovuta kusiyanitsa.

6.Surufare Purded Peels ndi lalifupi kwambiri

Izi ndizoyenera kuyesedwa. Kwa zida zowala kwambiri, mtunda pakati pa zikhomo ziwirizo ndi zazing'ono, ndipo mapiritsiwo ndiwowonda kwambiri. Mukakhazikitsa zikhomo zoyesera, ziyenera kunyamulidwa ndikugwedezeka. Ngati kapangidwe ka pad ndifupi kwambiri, ngakhale sikukhudza kukhazikitsa chipangizochi, koma chidzapangitsa kuti ziwedi zoyeserera.

Madambo amodzimodzi samakomedwa. Ngati mabowo owuma amafunikira kulembedwa, ziwembuzi ziyenera kupangidwa monga zero. Ngati mtengo wake wapangidwa, ndiye kuti deta yobowola imapangidwa, madzenje adzaonekera pa izi, ndipo mavuto adzabuka. Madambo amodzi ofanana monga mabowo obowoka ayenera kulembedwa mwapadera.

8. Pad kudutsa

Panthawi yobowola, kubowola pang'ono kudzaphwanyidwa chifukwa chobowola ambiri pamalo amodzi, zomwe zimayambitsa kuwonongeka kwa dzenje. Mabowo awiriwo mu bolodi-yosanjikiza likulu-losanjikiza, ndipo pambuyo pa vuto lakokedwa, lidzawoneka ngati mbale yotalikirana, zomwe zimapangitsa kuti musungunuke.

9. Pali malo odzaza kwambiri mu kapangidwe kake kapena mabatani odzaza ali ndi mizere yopyapyala

Zambiri zojambulira zimatayika, ndipo chithunzi chojambulira sichimakwanira. Chifukwa chodzaza chimakokedwa ndi imodzi mwa njira yopepuka yojambulira, kotero kuchuluka kwa zojambula zowoneka bwino ndizomwe zimapangidwa, zomwe zimawonjezera zovuta za deta.

Maulalo ena osagwiritsa ntchito zigawo zina zojambula. Zinali zoyambirira kukhala bolodi anayi koma oposa asanu a mabwalo adapangidwa, omwe adayambitsa kusamvana. Kuphwanya kapangidwe kake. Zojambulajambula ziyenera kusungidwa komanso zowonekera mukamapanga.
