Nzọụkwụ 1: Buru ụzọ jiri Altium Designer chepụta eserese na PCB nke sekit
Nzọụkwụ 2: Bipụta eserese PCB
Akwụkwọ mbufe thermal na-ebipụta adịghị mma nke ukwuu n'ihi na katrij ink nke ngwa nbipute adịghị mma, ma ọ dịghị mkpa, enwere ike ime ya maka mbufe na-esote.
Nzọụkwụ 3: Beechapụ akwụkwọ mbufe thermal e biri ebi
Nzọụkwụ 4: Nyefee sekit PCB
CCL na bee thermal nyefe akwụkwọ
Bee ihe mkpuchi ọla kọpa dịka nha nke bọọdụ PCB si dị
N'ezie, a ga-eji akwụkwọ sandpaper mara mma nke ọla kọpa clad laminate tupu ebufe (iji kpochapụ oyi akwa oxide)
Teepu n'otu nsọtụ akwụkwọ mbufe
Ihe ngosi mbufe a ma ama (PS: Daalụ Taobao onye nwere ike, naanị ị nweghị ike iche maka ya, mana ị nweghị ike ịhụ ya)
Mgbe 4 nyefechara, ọ dị mma, hapụ ya ka ọ dị jụụ ma kewaa ya
Olee otú ọ ga-esi dị irè?
N'ezie, ọ bụrụ na ịnweghị igwe na-ebufe okpomọkụ, ị nwekwara ike iji ígwè (*^__^*) Hee hee...
Nzọụkwụ 5: Dejupụta na nyefee PCB osisi
Ebe ọ bụ na katrij ebipụta adịghị mma, ị nwere ike iji akara iji mejupụta ebe a na-ebufeghị nke ọma.
Efere mbufe juru eju O(∩_∩)O~ Ọ dịghị njọ!
Nzọụkwụ 6: PCB osisi corrosion
Ajụla m!Gaa ozugbo na Taobao
Ihe eji eme ihe na-emebi emebi (mkpanaka na-ekpo ọkụ + aerator tank tank + igbe rọba = PCB osisi corrosion igwe)
Hụrụ onye n'ime ụlọ nyocha ịgbado ọkụ 8X8X8 ọkụ ka ọ na-eche ka corrosion gwụchaa
Ihe ha mere onwe ha zipụrụ bọọdụ ime ya
