A bana, sakamakon barkewar sabuwar kambi, samar da albarkatun PCB bai wadatar ba, kuma farashin albarkatun kasa yana tashi.Masana'antu masu alaƙa da PCB kuma sun sami tasiri sosai.Don ci gaba na yau da kullun na aikin, injiniyoyi suyi la'akari da haɓaka ƙira don rage farashin PCB.Sa'an nan, abin da dalilai zai shafi PCB masana'antu farashin?
Manyan abubuwan suna tasiri farashin PCB ɗin ku
1. Girman PCB da yawa
Yana da sauƙin fahimtar yadda girman da yawa zasu shafi farashin PCB, girman da yawa zasu cinye ƙarin kayan.
2. Nau'in kayan aikin da aka yi amfani da su
Wasu kayan aiki na musamman da ake amfani da su a wasu takamaiman yanayin aiki zai fi tsada fiye da kayan na yau da kullun. Ƙirƙirar Allolin da'ira da aka Buga ya dogara da dalilai da yawa na aikace-aikace, waɗanda aka fi gudanarwa ta mita da saurin aiki, da matsakaicin zafin aiki.
3. Yawan yadudduka
ƙarin yadudduka suna fassara zuwa ƙarin farashi saboda ƙarin matakan samarwa, ƙarin kayan aiki, da ƙarin lokacin samarwa.
4. PCB rikitarwa
Rubutun PCB ya dogara da adadin yadudduka da adadin vias akan kowane Layer, saboda wannan yana bayyana bambancin yadudduka inda vias ya fara da tsayawa, yana buƙatar ƙarin lamination da matakan hakowa a cikin tsarin masana'antar PCB.Masu sana'anta suna bayyana tsarin lamination azaman latsa yadudduka na tagulla biyu da dielectrics a tsakanin yaduddukan tagulla da ke kusa da juna ta amfani da zafi da matsa lamba don samar da laminate PCB mai yawa.
Yadda za a inganta ƙirar ku?
1. Track da rata lissafin lissafi- bakin ciki ya fi tsada.
2. Sarrafa impedance- ƙarin matakai matakan ƙara yawan farashi.
3. Girma da ƙidaya ramuka- ƙarin ramuka da ƙananan diamita suna tuƙi zuwa sama.
4. Toshe ko cika ta hanyar da ko an rufe su da tagulla - ƙarin matakan tsari suna ƙaruwa.
5. Copper kauri a cikin yadudduka- mafi girma kauri yana nufin mafi girma halin kaka.
6. Ƙarshen shimfidar wuri, amfani da zinariya da kauri - Ƙarin kayan aiki da matakan tsari yana ƙaruwa.
7. Tolerances- tighter tolerances ne tsada.
Sauran abubuwan suna tasiri farashin ku.
Waɗannan ƙananan abubuwan farashi da suka shafi nau'in III sun dogara ga duka biyun, mai ƙirƙira da aikace-aikacen PCB.Sun ƙunshi:
1. PCB kauri
2. Daban-daban jiyya na saman
3. Solder masking
4. Buga almara
5. Ajin aikin PCB (IPC Class II/ III da dai sauransu)
6. PCB kwane-kwane- musamman ga z- axis routing
7. Gefe ko gefe plating
PHILIFAST zai ba ku mafi kyawun shawarwari don taimaka muku rage farashin allunan PCB.
