Takulandilani patsamba lathu.

Kodi mawonekedwe ndi kapangidwe ka bolodi losindikizidwa ndi chiyani?

Kupanga

Thebolodi lozungulira panoamapangidwa makamaka ndi zotsatirazi
Mzere ndi chitsanzo (Pattern): Mzerewu umagwiritsidwa ntchito ngati chida choyendetsera pakati pa zoyambirira.M'mapangidwewo, mkuwa waukulu wamkuwa udzapangidwa ngati maziko ndi magetsi.Mizere ndi zojambula zimapangidwa nthawi imodzi.
Dielectric wosanjikiza: amagwiritsidwa ntchito posunga zotsekera pakati pa mizere ndi zigawo, zomwe zimadziwika kuti gawo lapansi.
Kupyolera mu mabowo / vias: Kupyolera mu mabowo amatha kupanga magawo opitilira awiri a mabwalo omwe amayenderana, okulirapo kudzera mabowo amagwiritsidwa ntchito ngati mapulagini, ndipo mabowo osadutsa (nPTH) nthawi zambiri amagwiritsidwa ntchito ngati zokwera pamwamba Pakuyika, ndizo. Zogwiritsidwa ntchito pokonza zomangira pamisonkhano. Solder resistant / Solder Mask: Sikuti zinthu zonse zamkuwa ziyenera kudya malata, kotero kuti malo omwe si a malata adzasindikizidwa ndi wosanjikiza wa zinthu (kawirikawiri epoxy resin) zomwe zimalekanitsa mkuwa kuti usadye malata. .Kuzungulira kwachidule pakati pa mizere yosadya malata.Malingana ndi njira zosiyanasiyana, zimagawidwa kukhala mafuta obiriwira, mafuta ofiira ndi mafuta a buluu.
Sewero la silika (Nthano / Chizindikiro / Silika): Ichi ndi gawo losafunikira.Ntchito yayikulu ndikuyika dzina ndi mawonekedwe a gawo lililonse pa bolodi ladera, lomwe ndi losavuta kukonza ndikuzindikiritsa pambuyo pa msonkhano.
Pamapeto Pamwamba: Popeza kuti pamwamba pa mkuwa ndi oxidized mosavuta m'madera ambiri, sangathe kuikidwa m'matanki (osauka kwambiri), choncho adzatetezedwa pamtunda wamkuwa womwe umafunika kudya malata.Njira zodzitetezera zimaphatikizapo tini yopopera (HASL), golide wamankhwala (ENIG), siliva (Immersion Silver), malata (Immersion Tin), organic solder protection agent (OSP), njira iliyonse ili ndi ubwino ndi zovuta, zomwe zimatchulidwa pamodzi ngati chithandizo chapamwamba.

Kunja

Bolodi lopanda kanthu (lopanda zigawo) limatchedwanso "Printed Wiring Board (PWB)".Chipinda chapansi pa bolodi palokha chimapangidwa ndi zinthu zotetezera zomwe sizimapindika mosavuta.Zozungulira zowonda zomwe zimatha kuwonedwa pamtunda ndi zojambula zamkuwa.Poyambirira, chojambula chamkuwa chinaphimba bolodi lonse, koma gawo lina linachotsedwa panthawi yopanga, ndipo gawo lotsalalo linakhala dera lopyapyala ngati mauna..Mizere iyi imatchedwa ma kondakitala kapena mawaya, ndipo amagwiritsidwa ntchito popereka kulumikizana kwamagetsi ku zigawo za PCB.
Kawirikawiri mtundu wa PCB ndi wobiriwira kapena bulauni, womwe ndi mtundu wa solder mask.Ndiwosanjikiza woteteza, womwe umatha kuteteza waya wamkuwa, kupewa kuzungulira kwafupipafupi komwe kumachitika chifukwa cha kutenthedwa kwa mafunde, ndikusunga kuchuluka kwa solder.Chophimba cha silika chimasindikizidwanso pa chigoba cha solder.Nthawi zambiri, zolemba ndi zizindikilo (zambiri zoyera) zimasindikizidwa pa izi kuwonetsa malo a gawo lililonse pa bolodi.Mbali yosindikiza chophimba imatchedwanso mbali ya nthano.
Pazogulitsa zomaliza, mabwalo ophatikizika, ma transistors, ma diode, magawo osagwira ntchito (monga resistors, capacitors, zolumikizira, ndi zina zambiri) ndi zida zina zamagetsi zimayikidwa pamenepo.Kupyolera mu kugwirizana kwa mawaya, kugwirizana kwa zizindikiro zamagetsi ndi ntchito zoyenera zingathe kupangidwa.
