Lokacin da ka zaɓi samfur buga kewaye hukumar (wanda kuma aka sani da PCB), kuna iya mamakin yadda tsarin taron PCB yake daidai. Manufar PCB ta canza sosai a cikin shekaru, godiya ga sabbin abubuwa a cikin sabbin fasahohin da suka ba da damar masana’antun hukumar kewaya su ƙirƙiri daidai da ƙwarewa.

Anan ne yadda ake yin PCB samfuri daidai.

Binciken injiniyan ƙarshen zamani

Kafin yin samfurin PCB, akwai fannoni da yawa waɗanda za a iya amfani da su don tsara sakamakon ƙarshe. Na farko, mai kera PCB zai yi nazarin tsarin allon a hankali (daftarin Gerber) kuma ya fara shirya hukumar, wanda ya lissafa umarnin masana’antun mataki-mataki. Bayan bita, injiniyoyi za su canza waɗannan tsare -tsaren zuwa tsarin bayanai wanda zai taimaka ƙera PCB. Injiniyan zai kuma duba tsarin don duk wata matsala ko tsabtacewa.

Ana amfani da wannan bayanan don ƙirƙirar allon ƙarshe kuma ya ba shi lambar lamba ta musamman. Wannan lambar tana bin tsarin aikin PCB. Ko da ƙaramin canje-canje ga bita na hukumar zai haifar da sabon lambar kayan aiki, wanda ke taimakawa tabbatar da cewa babu rudani yayin PCB da masana’anta da yawa.

Bayan bincika fayilolin da suka dace kuma zaɓi madaidaicin tsarin kwamitin da ya dace, ana fara buga hoton. Wannan shine farkon tsarin samarwa. Masu ɗaukar hoto suna amfani da lasers don zana alamu, allon siliki da sauran manyan hotuna akan PCB.

Lamination da hakowa

Ofaya daga cikin manyan nau’ikan allon allon da aka buga, wanda aka sani da multilayer PCBS, yana buƙatar lamination don haɗa filaye tare. Yawanci ana yin wannan ta amfani da zafi da matsi.

Bayan laminating samfurin, ƙwararren tsarin hakowa za a shirya shi don haƙa daidai da daidai cikin itace. Hanyar hakowa ba ta tabbatar da kuskuren ɗan adam ba yayin masana’antar PCB.

Copper shaida da plating

Layukan jan ƙarfe da aka ɗora ta hanyar electrolysis suna da mahimmanci ga aiki na duk samfuran allon da aka buga. Bayan electroplating, PCB bisa ƙa’ida ta zama farfajiyar farfajiya kuma ana zaɓar jan ƙarfe akan wannan saman ta hanyar magudanar ruwa. Waɗannan wayoyin jan ƙarfe sune hanyoyi masu gudana waɗanda ke haɗa maki biyu a cikin PCB.

Bayan yin gwaje -gwajen tabbatar da inganci akan PCB na samfur, an sanya su cikin sassan giciye kuma a ƙarshe an duba su don tsabta.
