Hababka Golaha PCBA: SMT iyo DIP
PCBA (Golaha Gudida Wareega ee Daabacan) habayntu waxay ku lug leedahay talaabooyin dhamaystiran oo ay ku jiraan wax soo saarka PCB, SMT (Surface Mount Technology) habaynta, DIP (Dual In-line Package) galinta, hubinta tayada, tijaabinta, iyo isu imaatinka si loo sameeyo alaab elektaroonik ah oo dhammaatay. Habkan waxa loo tixraacaa habaynta PCBA-da, ka-hortagga guddiga wareegga ka dib waxa loo yaqaan PCBA. Waxaa jira noocyo kala duwan oo PCBA ah, iyo dhowr habab oo isku imaatin ah oo loo isticmaalo habaynta PCBA. Hoosta, WonderfulPCB, oo ah warshad PCBA ah oo xirfad leh, ayaa bixisa horudhac kooban hababka isu-ururinta caadiga ah qaarkood.
Isku-dhafka Hal-dhinac ah
Habka isu-ururinta waxa uu isticmaalaa PCB-ga hal dhinac ah. Isku-dhafka isku-dhafka ah ee hal-dhinac ah, qaybaha SMT iyo qaybaha DIP ayaa loo qaybiyaa dhinacyada kala duwan ee PCB. Dhinaca alxanka ayaa ku go'doonsan hal dhinac, iyo Qaybaha SMT ayaa dhanka kale la dhigayaa. Habkani waxa uu shaqaalaysiiyaa PCB-ga hal dhinac ah iyo farsamada alxanka hirarka. Waxaa jira laba hab oo gaar ah oo isu-ururinta:
- SMT ugu horeysay, DIP LabaadQaybaha SMT (SMC/SMD) waxay ku rakiban yihiin dhinaca B ee PCB marka hore, ka dibna qaybaha DIP (THC) ayaa la gelinayaa dhinaca A.
- DIP First, SMT labaadQaybaha DIP (THC) ayaa marka hore la gelinayaa dhinaca A ee PCB-ga, ka dibna qaybaha SMT (SMD) ayaa lagu rakibaa dhinaca B.
Isku-dhafka Laba-dhinac leh
Noocaan PCBA assembly wuxuu isticmaalaa PCB-ga laba-geesoodka ah. Qaybaha SMT iyo DIP waxa lagu qasi karaa isla dhinac ama labada dhinac ee PCB. Habkan isu-ururinta, waxa kale oo jira farqi u dhexeeya rakibidda qaybaha SMT marka hore ama dambe. Doorashadu waxay ku xidhan tahay nooca SMC/SMD iyo cabbirka PCB-ga. Caadi ahaan, habka "SMT first" ayaa inta badan la isticmaalaa. Laba hab oo la isku keeno oo caadi ah waxaa ka mid ah:
- SMT iyo DIP oo isku dhinac ahQaybaha SMT iyo qaybaha DIP labaduba waa isku dhinac ee PCB-ga, inkastoo qaybaha DIP ay sidoo kale ka muuqan karaan labada dhinac. Habkan, qaybaha SMT (SMC/SMD) ayaa guud ahaan marka hore lagu rakibaa, oo ay ku xigto gelinta DIP.
- DIP Hal dhinac, SMT labada dhinac: Surface mount integrated circuits (SMIC) iyo THT qaybaha ayaa la dhigayaa dhinaca A ee PCB, halka SMC iyo transistor yar yar (SOT) la dhigo on B-side.
Dusha oo buuxa - Buur Golaha
Nooca kulanka, dhammaan PCB-yadu waa hal dhinac ama laba-geesood, oo kaliya qaybaha SMT ayaa la isticmaalaa, oo aan lahayn qaybo TTH. Dhammaan qaybaha si buuxda looma hagaajin SMT, markaa Habkan isu-ururinta ayaa ah mid si yar loo isticmaalo ficil ahaan. Waxaa jira laba hab oo isu-ururinta:
- Isku-xidhka Dusha-Dhex-Dhex-geeska leh.
- Isku-xidhka Dusha-Dheer-Laba-dhinac ah.
