"Single Sided PCB", kapena mutha kuyitcha ngati Single Layer PCB, kapena 1L PCB. Apo's palibe mkuwa umodzi wokha pa bolodi, zigawo za SMD kumbali imodzi (kupyolera muzitsulo kumbali inayo), komanso palibe PTH (yokutidwa ndi dzenje) kapena Via, ili ndi NPTH yokha (yopanda dzenje), kapena malo dzenje.

Ndilo gulu lotsika mtengo kwambiri, ndipo limagwiritsidwa ntchito pa bolodi losavuta kwambiri. Kuti apeze mtengo wotsika mtengo, nthawi zina anthu amagwiritsa ntchito CEM-1, CEM-3 m'malo mwa FR4, kupanga bolodi ladera. Nthawi zina, fakitale imatulutsa mkuwa umodzi kuchokera ku 2L CCL (copper clad laminate) ngati palibe 1L FR4 yaiwisi yaiwisi yomwe ilipo.

Apo'ndi gulu lina ochiritsira"2L PCB" yomwe ili ndi 2 copper trace, komanso imatchedwanso ngati"Mapiri Awiri PCB" (D/S PCB), ndi PTH (Via) ndiyofunika, koma sichitero't ali ndi dzenje lokwiriridwa kapena lakhungu. Zigawo zitha kusonkhanitsidwa mbali zonse pamwamba ndi pansi, kuti mutero't amafunika kudandaula za komwe angayike zida pa bolodi, ndipo osafunikira kugwiritsa ntchito zida zabowo zomwe zimakhala zodula kuposa SMD imodzi.

Panopa iyi ndi imodzi mwa mitundu yotchuka kwambiri ya PCB Padziko Lapansi, ndipo tikhoza kupereka maola 24 mwamsanga kutembenukira kwa iwo. Dinani apa kuti muwone Nthawi Yotsogolera yamitundu yonse iwiri yama board ozungulira.


Kapangidwe ka Single Side (1L) PCB

Nayi gawo lofunikira la mbali imodzi (S/S) FR4 PCB (kuyambira pamwamba mpaka pansi):

Top silkscreen/Nthano: kudziwa dzina la PAD iliyonse, bolodi gawo nambala, deta, etc;

Kumaliza Pamwamba Pamwamba: kuteteza mkuwa wowonekera ku okosijeni;

Top Soldermask (zophimba): kuteteza mkuwa ku okosijeni, kuti usagulitsidwe panthawi ya SMT;

Top Trace: mkuwa wokhazikika molingana ndi kapangidwe kake kuti ugwire ntchito zosiyanasiyana

Zachigawo / Pakatikati: Zosagwiritsa ntchito monga FR4, FR3, CEM-1, CEM-3.

Mapangidwe a Pawiri Mbali (2L) PCB

Top silkscreen/Nthano: kudziwa dzina la PAD iliyonse, bolodi gawo nambala, deta, etc;

Kumaliza Pamwamba Pamwamba: kuteteza mkuwa wowonekera ku okosijeni;

Top Soldermask (zophimba): kuteteza mkuwa ku okosijeni, kuti usagulitsidwe panthawi ya SMT;

Top Trace: mkuwa wokhazikika molingana ndi kapangidwe kake kuti ugwire ntchito zosiyanasiyana

Zachigawo / Pakatikati: Zosagwiritsa ntchito monga FR4, FR5

Kutsata pansi (ngati kulipo): (monga momwe tafotokozera pamwambapa)

Pansi soldermask (zophimba): (zofanana ndi zomwe tafotokozazi)

Kumaliza pamwamba: (monga momwe tafotokozera pamwambapa)

Pansi pa silkscreen/nthano: (monga momwe tafotokozera pamwambapa)
