Nezve Via-In-Pad PCB

Iyo Via-In-Pad PCBs kazhinji maburi mapofu, ayo anonyanya kushandiswa kubatanidza iyo yemukati layer kana yechipiri yekunze layer yeHDI PCB neyekunze layer, kuitira kuvandudza mashandiro emagetsi uye kuvimbika kwezvigadzirwa zvemagetsi, kupfupisa chiratidzo. kutapurirana waya, kuderedza inductive reactance uye capacitive reactance yetambo yekutapurirana, pamwe nekukanganisa kwemukati nekunze kwemagetsi.

Inoshandiswa kugadzirira.Dambudziko guru remaburi eplug muindasitiri yePCB kudonha kwemafuta kubva kumaburi eplug, izvo zvinogona kunzi chirwere chinoramba chiripo muindasitiri iyi.Iyo inokanganisa zvakanyanya kunaka kwekugadzira, nguva yekuendesa uye kugona kwePCB.Parizvino, maPCB mazhinji epamusoro-soro ane rudzi urwu rwekugadzira.Naizvozvo, PCB indasitiri inoda nekukurumidza kugadzirisa dambudziko rekudonha kwemafuta kubva kumaburi eplug

Zvinhu Zvikuru Zvekubuda Kwemafuta Kubva Via In Pad Plug Hole

Kupatsanura pakati pe plug gomba uye padhi: mune chaiyo PCB anti-welding yekugadzira maitiro, kunze kwekunge gomba replate riri nyore kutiza.Imwe plug gomba uye hwindo spacing isingasviki 0.1mm 4mil) uye plug gomba uye anti-soldering hwindo tangential, mharadzano ndiro zvakare nyore kuvapo mushure mekurapa kubuda kwemafuta;

PCB ukobvu uye aperture: kukora kweplate uye aperture zvakabatana zvakanaka nedhigirii uye chikamu chekubuda kwemafuta;

Parallelic firimu dhizaini: kana iyo Via-In-Pad PCB kana diki buri rinopindirana padhi, iyo parallelic firimu rinowanzo gadzira nzvimbo yekufambisa mwenje pahwindo (kufumura ingi mugomba) "kunzvenga inki mukati. gomba rinopinda mupedhi panguva yekuvandudzwa, asi dhizaini yekufambisa mwenje idiki zvakanyanya kuti iwane mhedzisiro yekuratidzwa, uye nzvimbo yekufambisa mwenje yakakurisa kuti ikonzerese nyore.Inogadzira mafuta egirini paPAD.

Kurapa mamiriro: nekuti dhizaini yenzvimbo inopenya yeVia-In-Pad PCB kune firimu inofanira kunge iri diki pane gomba, chikamu cheinki mugomba chakakura kupfuura chinopenya kana chaiswa pachena chisina kuvhenekwa.Ingi haisi photosensitive kurapa, kusimudzira mushure mekuda kwese kudzosera kuratidzwa kana UV kamwe, kuitira kurapa inki pano.A layer yekurapa firimu inoumbwa pamusoro pegomba kudzivirira kuwedzera kwekupisa kweinki mugomba mushure mekurapa.Mushure mekurapa, iyo yakareba nguva yechikamu chekushisa kwakadzika, uye kuderera kwekushisa kwechikamu chekushisa kwakadzika, kuduku chiyero uye chiyero chekubuda kwemafuta;

Plugging inki: vagadziri vakasiyana veinki formula dzakasiyana mhando mhedzisiro vanozovewo nemusiyano.
