4. faele ea BOM
Faele ea BOM ke lethathamo la lisebelisoa.Lisebelisoa tsohle tse sebelisoang ts'ebetsong ea PCBA, ho kenyelletsa le bongata ba lisebelisoa le tsela ea ts'ebetso, ke motheo oa bohlokoa oa ho reka thepa.Ha PCBA e qotsitsoe, e boetse e hloka ho fuoa setsi sa ho sebetsa sa PCBA.
5. SMT
SMT ke khutsufatso ea "Surface Mounted Technology", e bolelang ts'ebetso ea khatiso ea solder paste, ho kenya likarolo tsa maqephe lereflow ontongsolder ka boto ea PCB.
6. Mochine oa khatiso oa solder
Khatiso ea solder paste ke ts'ebetso ea ho beha peista ea solder holim'a letlooa la tšepe, ho phunya pente ea solder ka lesoba la letlooa la tšepe ka har'a scraper, le ho hatisa ka nepo pente ea solder holim'a PCB pad.
7. SPI
SPI ke sebui sa botenya ba peista ea solder.Kamora ho hatisoa ha solder paste, ho hlokahala ho fumana SIP ho bona boemo ba khatiso ea solder paste le ho laola phello ea khatiso ea solder paste.
8. Reflow welding
Reflow soldering ke ho kenya PCB e kentsoeng mochineng oa reflow solder, 'me ka mocheso o phahameng ka hare, pente ea solder e tla futhumatsoa hore e be metsi,' me qetellong ho tjheseletsa ho tla phethoa ka ho pholile le ho tiisa.
9. AOI
AOI e bolela ho lemoha ka tsela e iketsang.Ka papiso ea scanning, phello ea welding ea boto ea PCB e ka bonoa, 'me mefokolo ea boto ea PCB e ka bonoa.
10. Ho lokisa
Ketso ea ho lokisa AOI kapa mapolanka a nang le bothata a bonoeng ka bowena.
11. DIP
DIP e khutsufetse bakeng sa "Dual In-line Package", e bolelang theknoloji ea ts'ebetso ea ho kenya likarolo tse nang le lithapo ka har'a boto ea PCB, ebe e li sebetsa ka ho soasoa ka maqhubu, ho poma maoto, ho soasoa ka poso, le ho hlatsoa lipoleiti.
12. Wave soldering
Wave soldering ke ho kenya PCB ka har'a sebōpi sa wave soldering, ka mor'a ho phalla ha metsi, preheating, wave soldering, cooling le lihokelo tse ling ho phethela welding ea boto ea PCB.
13. Khaola likarolo
Khaola likarolo ho welded PCB boto ho boholo bo loketseng.
14. Kamora ts'ebetso ea welding
Ka mor'a ho tjheseletsa tshebetso ke ho lokisa tjheseletsa le ho lokisa PCB e sa ka botlalo tjheseletsa ka mor'a tlhahlobo.
15. Ho hlatsoa lipoleiti
Boto ea ho hlatsoa ke ho hloekisa lintho tse setseng tse kotsi tse kang ho phalla ka lihlahisoa tse felileng tsa PCBA e le hore li kopane le bohloeki bo tloaelehileng ba tšireletso ea tikoloho bo hlokoang ke bareki.
16. Tse tharo tsa anti pente fafatsa
Tse tharo tse thibelang pente ho fafatsa ke ho fafatsa lera la ho roala ho khethehileng holim'a boto ea litšenyehelo ea PCBA.Kamora ho fola, e ka bapala ts'ebetso ea ho kenya letsoho, bopaki ba mongobo, bopaki ba ho lutla, bopaki ba ho ts'oha, bopaki ba lerōle, bopaki ba kutu, bopaki ba botsofali, bopaki ba hlobo, likarolo tse hlephileng le ho hanyetsa corona.E ka eketsa nako ea polokelo ea PCBA le ho arola khoholeho ea ka ntle le tšilafalo.
17. Letlapa la Welding
Phetolelo ke sebaka sa PCB se atolositsoeng sebakeng, ha ho na sekoaelo sa pente ea insulation, se ka sebelisoang bakeng sa likarolo tsa welding.
18. Encapsulation
Ho paka ho bolela mokhoa oa ho paka oa likarolo, sephutheloana se arotsoe haholo ka DIP habeli - line le SMD patch packaging tse peli.
19. Pin sebaka
Pin spacing e bolela sebaka se pakeng tsa mela e bohareng ea lithapo tse bapileng tsa karolo e hlomamisoang.
20. QFP
QFP e khuts'oane bakeng sa "Quad Flat Pack", e bolelang potoloho e kopantsoeng e kopantsoeng ka holim'a sephutheloana se tšesaane sa polasetiki se nang le li-airfoil tse khutšoane mahlakoreng a mane.
