1. PCB Loj
[Tom qab keeb kwm yav dhau los] Qhov loj ntawm PCB txwv yog txwv los ntawm lub peev xwm ntawm hluav taws xob ua cov khoom siv khoom lag luam. Yog li, tus PCB tsim nyog loj yuav tsum tau txiav txim siab thaum tsim cov phiaj xwm cov khoom.
(1) Qhov ntau tshaj plaws PCB loj uas tuaj yeem muab cov khoom siv SMT los ntawm cov ntaub ntawv PCB los, feem ntau yog 20 "× 2410mm (Rearth)
(2) Qhov loj me uas yog qhov loj me uas phim cov khoom ntawm SMT cov kab ntau lawm, uas yog conducive rau cov khoom siv thiab tshem tawm cov khoom siv ntawm cov khoom siv.
(3) Cov PCB me me yuav tsum tau tsim los ua kev cuam tshuam los txhim kho kev ua haujlwm ntawm tag nrho cov kab ntau lawm.

【Qauv tsim yuav tsum muaj】
(1) Feem ntau, qhov loj tshaj plaws ntawm PCB yuav tsum tau tsawg nyob rau hauv ntau ntawm 460mm × 610mm.
(2) Qhov loj uas pom qhov loj me yog (200 ~ 250) hli × (250 ~ 350) mm, thiab cov nam, thiab cov nam, thiab cov kev sib piv yuav tsum yog "2.
(3) Rau PCB loj "125mm × 125 hli, tus PCB yuav tsum teeb tsa kom muaj qhov loj me.

2, PCB zoo
[Tom qab cov lus piav qhia] SHT cov khoom siv ntau lawm siv hloov cov kev sib tw hloov pauv, thiab tsis tuaj yeem hloov pauv tsis xwm yeem, tshwj xeeb yog cov khoob ntawm cov fab.

【Qauv tsim yuav tsum muaj】
(1) cov duab ntawm PCB yuav tsum yog cov xwm txheej li ib txwm nrog cov ces kaum.
(2) Txhawm rau kom muaj kev ruaj ntseg ntawm cov txheej txheem xa khoom, tshwj xeeb yog kev hloov pauv ntawm cov txheej txheem yoj ntawm cov txheej txheem SOLDS Card Board.
(3) Rau cov laug cam ntshiab SMT, cov khoob tso cai, tab sis cov sib txawv loj yuav tsum tsawg dua ib feem peb ntawm qhov ntev ntawm sab uas nws nyob. Yog tias nws tshaj qhov ua tau no, cov qauv tsim sab yuav tsum tau sau.
(4) Ntxiv rau cov chamfering tsim ntawm cov ntawv tso rau sab, ntawm chamfering tsim los ntawm (1 ~ 1.5) × 45 ° chamfering ntawm ob sab los pab txhawb kev ntxig.

3. Hloov sab
[Tom qab cov lus piav qhia] qhov loj me ntawm cov ntsiab lus conveye yog nyob ntawm cov kev xav tau ntawm kev coj ntawm cov lus qhia ntawm cov khoom siv. Luam Ntawv Machine, Tso Machine thiab Tsaws Soldering Furning Furnaces feem ntau yuav tsum tau ua kom zoo dua 3.5mm.

【Qauv tsim yuav tsum muaj】
(1) Txhawm rau txo cov deformation ntawm pcb thaum solding, txoj kev taw qhia ntev ntawm tus kab mob tsis raug cai; Rau lub imposition pcb, txoj kev taw qhia ntev yuav tsum tau siv ua qhov kev xa khoom.
(2) Feem ntau, ob sab ntawm PCB lossis kev hloov kho cov kev xa tawm yog siv los ua kev sib kis. Qhov tsawg kawg ntawm qhov chaw sib kis tau yog 5.0 hli. Yuav tsum tsis muaj cov khoom sib xyaw lossis cov pob qij txha sib dhos ntawm sab xub ntiag thiab sab nraum qab ntawm kis tau sab.
(3) Tsis yog kis, tsis muaj kev txwv cov khoom SMT, nws yog qhov zoo dua rau qhov chaw 2.5MM txwv tsis pub.

4, muab qhov chaw
[Tom qab cov lus piav qhia] ntau cov txheej txheem xws li kev ua haujlwm ua, sib dhos, sib dhos, thiab kuaj yuav tsum muaj qhov chaw tseeb ntawm PCB. Yog li ntawd, nws feem ntau yuav tsum tsim qauv rau qhov chaw.

【Qauv tsim yuav tsum muaj】
(1) rau txhua tus PCB, tsawg kawg ob txoj haujlwm yuav tsum yog tsim, zoo nkauj yog siv rau kev muab tso rau thiab tom kawg yog siv rau kev qhia.
Nws tsis muaj qhov tshwj xeeb rau qhov chaw tso cai, nws tuaj yeem tsim los raws li cov kev qhia tshwj xeeb ntawm koj lub Hoobkas, thiab cov kev pom zoo ntawm txoj kab ke ntawm koj, thiab cov lus pom zoo kom ua kom lub hom phiaj 2.4mm thiab 3.0mm.
Qhov chaw muab yuav tsum tsis yog-metersallized qhov. Yog tias tus PCB yog lub punched PCB, lub chaw tso pa yuav tsum tau tsim nrog lub qhov phaj kom ntxiv dag zog rau cov rigidity.
Qhov ntev ntawm cov lus qhia feem ntau yog 2 zaug ntawm txoj kab uas hla.
Lub chaw nruab nrab ntawm lub qhov chaw yuav tsum tau ntau tshaj 5.0mm deb ntawm kev xa mus rau ntug, thiab ob lub qhov chaw yuav tsum kom deb li deb tau. Nws raug nquahu kom npaj lawv nyob ntawm lub ces kaum ntawm PCB.
(2) Rau mixed pcb (PCBA nrog cov ntsaws nruab, qhov chaw ntawm lub qhov chaw yuav tsum tau sib qhia ntawm sab pem hauv ntej thiab sab nraum qab.

5. Lub cim ua haujlwm
[Tom qab cov lus piav qhia] niaj hnub tso machine, luam tawm cov tshuab, luam tawm cov khoom siv tshuaj xyuas (SPI), thiab lwm yam siv cov khoom siv kho qhov muag. Yog li, kev tawm tsam cov cim cim yuav tsum raug tsim ntawm PCB.

【Qauv tsim yuav tsum muaj】
(1) Cov cim tso tawm tau muab faib ua cov cim thoob ntiaj teb (thoob ntiaj teb fiducial) thiab cov chaw hauv zos hauv zos (hauv zos fiducial). Tus qub yog siv rau txoj haujlwm ntawm tag nrho cov rooj tsavxwm, thiab tom kawg yog siv rau txoj haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm lossis cov khoom siv nplua.
(2) Lub cim kho qhov muag tau tuaj yeem tsim tau rau hauv ib lub xwmfab, lub voj voog pob zeb diamond, tus ntoo khaub lig, ib leeg, thiab qhov siab yog 2.0mm. Feem ntau, nws raug nquahu kom tsim qauv ø1.0m hloov tooj liab txhais qauv qauv. Kev noj rau hauv tus account qhov sib piv ntawm cov khoom xim thiab ib puag ncig, tawm ib qho chaw tsis yog 1mm loj dua li cov cim optical. Tsis muaj cov cim tso cai sab hauv. Peb nyob rau tib lub rooj tsavxwm muaj lossis tsis muaj ntawm tooj liab ntawv ci nyob rau hauv txheej sab hauv nyob rau hauv txhua lub cim yuav tsum ua kom zoo ib yam.
(3) Ntawm PCB saum npoo nrog SMD Cheebtsam, nws raug nquahu kom tso peb lub cim ntawm lub PCB (peb lub ntsiab lus txiav txim siab dav hlau, uas tuaj yeem pom cov tuab ntawm lub tshuab ua tuab).
(4) rau kev ua kom yuam kev, ntxiv rau peb lub rooj sib txawv ntawm cov cim, nws yog qhov zoo dua rau kev tsim ob lossis peb qhov kev cuam tshuam kho qhov muag cim ntawm cov kab pheeb ces kaum ntawm txhua lub rooj tsavxwm.
(5) Rau cov khoom siv xws li LFP nrog cov pob tw nrug nyob qib ≤0.8mm, cov khoom siv kho tshiab hauv zos yuav tsum tau teeb tsa ntawm cov kab pheeb ces kaum rau kev muab cov chaw zoo.
(6) Yog tias muaj cov sib xyaw ua ke ntawm ob tog, yuav tsum muaj kev kho qhov muag rau txhua sab.
(7) Yog tias tsis muaj qhov chaw nyob ntawm tus PCB, qhov chaw nruab nrab ntawm lub cim kho kho kho qhov muag yuav tsum yog 6.5mm deb ntawm PCB kis tus ntug. Yog tias muaj lub qhov chaw nyob ntawm PCB, qhov chaw nruab nrab ntawm lub cim kho kho kho qhov muag yuav tsum yog tsim nyob rau sab ntawm lub plawv ntawm lub PCB.
