1. Padi yopangidwayo iyenera kukwaniritsa zofunikira za kukula, m'lifupi ndi matayala a pini ya chipangizo chandamale.
Chisamaliro chapadera chiyenera kuperekedwa ku: cholakwika cha dimensional chopangidwa ndi pini ya chipangizocho chiyenera kuganiziridwa pakupanga - makamaka zipangizo zolondola komanso zatsatanetsatane ndi zolumikizira.

Kupanda kutero, zitha kubweretsa magulu osiyanasiyana amtundu womwewo wa zida, nthawi zina zokolola zowotcherera zimakhala zazikulu, nthawi zina zovuta zazikulu zopanga zimachitika!

Chifukwa chake, mawonekedwe ofananira a pad (oyenera komanso odziwika kwa opanga ambiri opanga ma pad size ya chipangizo) ndikofunikira kwambiri!

Pankhani iyi, zofunika zosavuta ndi njira zoyendera ndi:

Ikani kwenikweni chandamale chipangizo pa PAD wa bolodi PCB kuonerera, ngati aliyense pini chipangizo ndi lolingana PAD dera.

Mapangidwe a phukusi la pedi iyi kwenikweni si vuto lalikulu.Mosiyana ndi zimenezi, ngati mapini ena mulibe pad, si bwino.

2. Padi yopangidwayo iyenera kukhala ndi chizindikiritso chodziwikiratu, makamaka chizindikiro cha polarity chapadziko lonse lapansi komanso chosavuta kusiyanitsa.Kupanda kutero, pamene palibe oyenerera PCBA chitsanzo kwa kutchulidwa, ngati chipani chachitatu (SMT fakitale kapena kunja outsourcing payekha) kuchita ndondomeko kuwotcherera, adzakhala sachedwa kusintha polarity ndi kuwotcherera molakwika!

3. Padi yopangidwa iyenera kukwaniritsa magawo opangira, zofunikira ndi luso la fakitale yapadera ya PCB yokha.

Mwachitsanzo, pedi mzere kukula, mzere katayanitsidwe, khalidwe kutalika ndi m'lifupi kuti akhoza kupangidwa, etc. Ngati kukula PCB ndi lalikulu, Ndi bwino kuti kupanga molingana ndi wotchuka ndi wamba PCB fakitale ndondomeko mu msika, kotero kuti pamene ogulitsa PCB asinthidwa chifukwa cha khalidwe kapena mgwirizano wa bizinesi, pali opanga PCB ochepa kwambiri omwe angasankhe ndipo ndondomeko yopangira ikuchedwa.
