Zomwe timanena nthawi zambiri ndi " FR-4 Fiber Class Material PCB Board " ndi dzina lachidziwitso cha kalasi ya zipangizo zosagwira moto. Zimayimira chidziwitso chakuthupi kuti utomoni uyenera kuzimitsa yokha pambuyo powotchedwa. Si dzina lakuthupi, koma mtundu wa zinthu. pali mitundu yambiri ya zida za FR-4 zomwe zimagwiritsidwa ntchito pama board ozungulira pano, koma ambiri amapangidwa ndi otchedwa Tera-Function epoxy resin kuphatikiza filler (Filler) ndi fiber magalasi Zomwe zimapangidwa.
Flexible kusindikizidwa dera bolodi (Flexible Printed Circuit Board, chidule cha FPC) imatchedwanso flexible printed circuit board, kapena flexible printed circuit board.The flexible kusindikizidwa dera bolodi ndi mankhwala kuti anapangidwa ndi kupangidwa pa flexible gawo lapansi mwa kusindikiza. 
Pali mitundu iwiri ikuluikulu yamagawo osindikizira a board: organic substrate materials and inorganic substrate materials, and organic substrate materials are most used.Magawo a PCB omwe amagwiritsidwa ntchito ndi osiyana ndi magawo osiyanasiyana.Mwachitsanzo, 3 mpaka 4 matabwa osanjikiza ayenera kugwiritsa ntchito zida zophatikizika kale, ndipo matabwa a mbali ziwiri nthawi zambiri amagwiritsa ntchito magalasi-epoxy. Posankha pepala, tiyenera kuganizira zotsatira za SMT Pamsonkhano wapakompyuta wopanda kutsogolera, chifukwa cha kuwonjezeka kwa kutentha, mlingo wa kupindana kwa bolodi losindikizidwa pamene kutentha ukuwonjezeka.Chifukwa chake, pamafunika kugwiritsa ntchito bolodi yokhala ndi digiri yaying'ono yopindika mu SMT, monga gawo lapansi lamtundu wa FR-4.
Popeza kukulitsa ndi kupsinjika kwa gawo lapansi pambuyo pakutentha kumakhudza zigawo zake, kumapangitsa kuti ma elekitirodi atuluke ndikuchepetsa kudalirika.Choncho, coefficient kukulitsa zinthu ayenera kuperekedwa chidwi posankha zinthu, makamaka pamene chigawo chachikulu kuposa 3.2 × 1.6mm.PCB ntchito pamwamba msonkhano luso amafuna mkulu matenthedwe madutsidwe, kwambiri kutentha kukana (150 ℃, 60min) ndi solderability (260 ℃, 10s), mkulu mkuwa zojambulazo adhesion mphamvu (1.5 × 104Pa kapena kuposa) ndi kupinda mphamvu (25 × 104Pa), high conductivity ndi yaing'ono dielectric mosalekeza, punchability zabwino (zolondola ± 0.02mm) ndi n'zogwirizana ndi oyeretsera, kuwonjezera, maonekedwe akufunika kukhala yosalala ndi lathyathyathya, popanda warping, ming'alu, zipsera ndi mawanga dzimbiri, etc. 
Kusankha makulidwe a PCB The makulidwe a bolodi kusindikizidwa dera ndi 0.5mm, 0.7mm, 0.8mm, 1mm, 1.5mm, 1.6mm, (1.8mm), 2.7mm, (3.0mm), 3.2mm, 4.0mm, 6.4mm, amene 0.7mm mm ndi 1.5 PCB yokhala ndi makulidwe a mm imagwiritsidwa ntchito popanga matabwa okhala ndi mbali ziwiri ndi zala zagolide, ndipo 1.8mm ndi 3.0mm sakhala muyeso. Kuchokera pakupanga, kukula kwa bolodi losindikizidwa kuyenera kukhala kosachepera 250 × 200mm, ndipo kukula koyenera kumakhala (250 ~ 350mm) × (200 × 250mm).Kwa ma PCB okhala ndi mbali zazitali zosakwana 125mm kapena mbali zazikulu zosakwana 100mm, zosavuta Kugwiritsa ntchito njira ya jigsaw. Ukadaulo wokwera pamwamba umafotokoza kuchuluka kwa gawo lapansi lopindika ndi makulidwe a 1.6mm ngati tsamba lapamwamba lankhondo ≤0.5mm ndi tsamba lotsika lankhondo ≤1.2mm
