Ndi zovuta ziti zomwe ziyenera kutsatiridwa pakuwunika pakutsimikizira kwa PCB?

Mu umboni wa PCB, wosanjikiza wotsutsa-malata amawunikiridwa kale pachojambula chamkuwa kuti asungidwe kunja kwa bolodi, ndiye kuti, gawo lojambula la dera, ndiyeno zojambulazo zamkuwa zotsalazo zimakhazikika. kutali, komwe kumatchedwa etching.

Choncho, muPCB umboni, ndi zovuta ziti zomwe ziyenera kutsatiridwa mu etching?

Chofunikira chamtundu wa etching ndikutha kuchotseratu zigawo zonse zamkuwa kupatula pansi pa anti-etching layer.Kunena zowona, mtundu wa etching uyenera kuphatikizira kufanana kwa waya m'lifupi ndi kuchuluka kwa etching yam'mbali.

Vuto la etching m'mbali nthawi zambiri limadzutsidwa ndikukambidwa mu etching.Chiŵerengero cha etch m'lifupi mwake ndi kuya kwa etch chimatchedwa etch factor.M'makampani osindikizira ozungulira, digiri yaying'ono yam'mbali kapena yotsika kwambiri ndiyokhutiritsa kwambiri.Mapangidwe a zida za etching ndi nyimbo zosiyanasiyana za etching solution zidzakhudza etching factor kapena mbali etching degree.

Munjira zambiri, mtundu wa etching umakhalapo kale gulu lozungulira lisanalowe mu makina ojambulira.Chifukwa pali mgwirizano wapakati kwambiri pakati pa njira zosiyanasiyana zowonetsera PCB, palibe ndondomeko yomwe sichikhudzidwa ndi njira zina ndipo sichikhudza njira zina.Mavuto ambiri omwe adadziwika kuti ndi mtundu wa etch analipo kale pakuvula.

Kunena mwamwano, kutsimikizira kwa PCB kumalowa pagawo lokhazikika.Mu chitsanzo electroplating njira, dziko abwino ayenera kukhala: kuchuluka kwa makulidwe a mkuwa ndi malata kutsogolo pambuyo electroplating sayenera upambana makulidwe a electroplating photosensitive filimu, kotero kuti chitsanzo electroplating kwathunthu yokutidwa mbali zonse za filimuyo."Khoma" limatchinga ndipo limayikidwa mmenemo.Komabe, mukupanga kwenikweni, mawonekedwe okutira ndi okhuthala kwambiri kuposa mawonekedwe a photosensitive;popeza kutalika kwa zokutira kumaposa filimu yojambula zithunzi, pamakhala chizolowezi chodzikundikira kumbuyo, ndipo gawo la tini kapena lotsogola lomwe limakutidwa pamwamba pa mizereyo limafikira mbali zonse ziwiri, ndikupanga "Edge", gawo laling'ono la filimuyo. imakutidwa pansi pa "m'mphepete"."Mphepete" yopangidwa ndi tini kapena lead-tin imapangitsa kuti zikhale zosatheka kuchotsa kwathunthu filimu ya photosensitive pochotsa filimuyo, ndikusiya kachigawo kakang'ono ka "glue otsalira" pansi pa "m'mphepete", zomwe zimapangitsa kuti zikhale zosakwanira.Mizere imapanga "mizu yamkuwa" kumbali zonse ziwiri pambuyo pa kutsetsereka, zomwe zimachepetsera mizere, kuchititsabolodi losindikizidwakulephera kukwaniritsa zofuna za makasitomala ndipo mwina kukanidwa.Mtengo wopangira PCB wakula kwambiri chifukwa chakukanidwa.

Pakutsimikizira kwa PCB, pakangokhala vuto ndi njira yolumikizira, liyenera kukhala vuto la batch, lomwe pamapeto pake lingayambitse zoopsa zobisika kumtundu wazinthu.Choncho, m'pofunika kwambiri kupeza yoyeneraWopanga umboni wa PCB.

PCBFuture yadzipangira mbiri yathu yabwino pamsika wapagulu wa PCB wamtundu wa PCB wamtundu wa PCB komanso voliyumu yotsika, msonkhano wapakatikati wa PCB.Zomwe makasitomala athu ayenera kuchita ndikutumiza mafayilo amapangidwe a PCB ndi zofunikira kwa ife, ndipo titha kusamalira ntchito ina yonse.Ndife okhoza kupereka ntchito zosagonjetseka za PCB koma kusunga ndalama zonse mkati mwa bajeti yanu.

Ngati mukuyang'ana wopanga msonkhano wa Turnkey PCB, chonde tumizani mafayilo anu a BOM ndi mafayilo a PCB kwasales@pcbfuture.com. Mafayilo anu onse ndi achinsinsi kwambiri.Tikutumizirani mawu olondola okhala ndi nthawi yotsogolera mu maola 48.
