Mu PCBA processing zomera zamagetsi processing, ndi PCB kuwala bolodi ayenera kudutsa njira zambiri kukhala wathunthu PCBA bolodi.Pali zida zambiri zopangira pazitali zazitali zopangira, zomwe zimatsimikiziranso kuthekera kwa fakitale ya PCBA.ETA yotsatirayi ikupatsani chidziwitso chachidule cha zida ndi ntchito za PCBA processing.
1, SMT chosindikizira cholembera
Chosindikizira chosindikizira cha SMT chokonzedwa ndi PCBA nthawi zambiri chimakhala ndi kuyika mbale, phala la solder, embossing, ndi bolodi yotumizira.Nthawi zambiri, bolodi loyenera kusindikizidwa limayikidwa koyamba patebulo losindikizira, kenako phala la solder kapena guluu wofiira amasindikizidwa papepala lofananira kudzera muzitsulo zachitsulo ndi zopukutira kumanzere ndi kumanja kwa makina osindikizira, ndi PCB. ndi kutayikira yunifolomu ndikulowetsa ku PCB kudzera pa malo opatsirana.Makina oyika amangoyika okha.
2, Sankhani ndi kuika makina (chip mounter)
Makina osankhira ndi malo amayikidwa mumzere wopanga PCBA pambuyo pa chosindikizira cha solder phala, chomwe ndi chipangizo choyika molondola zida zapamtunda pa PCB pads posuntha mutu woyika.
3,Reflow uvuni(SMD Soldering)
M'kati mwa ng'anjo ya reflow pali dera lotentha lomwe limatenthetsa mpweya kapena nayitrogeni mpaka kutentha kokwanira ndikuliwombera pa bolodi lomwe lalumikizidwa ku gawolo, kulola kuti solder kumbali zonse ziwiri za chigawocho chisungunuke ndikugwirizanitsa ndi chachikulu. bolodi.Ubwino wa ndondomekoyi ndi kuti kutentha ndi kosavuta kulamulira, makutidwe ndi okosijeni angapewe panthawi ya soldering, ndipo mtengo wopangira PCBA foundry ndi wosavuta kulamulira.
4, ayi
AOI ndi chipangizo chodziwikiratu choyang'ana chomwe chimakhazikika pa mfundo za kuwala kuti zizindikire zolakwika zomwe zimachitika popanga kuwotcherera.AOI ndi mtundu watsopano waukadaulo woyesera womwe ukubwera kuchokera kumayiko omwe akubwera, koma wakula mwachangu.Opanga ambiri ayambitsa zida zoyezera za AOI.Zikadziwika zokha, makinawo amangoyang'ana PCB kudzera mu kamera, amasonkhanitsa zithunzi, ndikufanizira zolumikizira zoyesedwa ndi magawo oyenerera mu database.Pambuyo pokonza zithunzi, zolakwika pa PCB zimayang'aniridwa, ndipo zolakwikazo zimawonetsedwa / kuzindikiridwa kudzera muwonetsero kapena zizindikiro zokha.Tulukani kuti mudzakonze ndi ogwira ntchito yokonza.
5, Makina ometa zida
Amagwiritsidwa ntchito podula ndi kusokoneza zigawo za pini.
6, Wave soldering makina
Wave soldering makina ndi kupanga soldering pamwamba pa bolodi mwachindunji kukhudzana ndi mkulu kutentha madzi malata pofuna kuwotcherera zolinga.Tini yamadzi otentha kwambiri imakhala ndi malo otsetsereka, ndipo malata amadzimadzi amapanga chinthu chofanana ndi mafunde ndi njira zapadera, choncho amatchedwa "wave soldering".Chinthu chachikulu ndi mipiringidzo ya solder.
7, Ng'anjo ya malata
Ambiri, malata ng'anjo amatanthauza chida kuwotcherera ntchito PCBA pakompyuta kuwotcherera.
8, Makina otsuka
Ntchito kuyeretsa bolodi PCBA kuchotsa zotsalira pa bolodi soldered.
9, ICT test fixture
Mayeso a ICT amagwiritsidwa ntchito poyesa mayeso a probe contact PCB masanjidwe kuti azindikire mawonekedwe otseguka a PCBA, dera lalifupi, ndi kugulitsa magawo onse.
10, mawonekedwe a mayeso a FCT
FCT (Functional Test) Imatanthawuza kuyerekezera kwa malo ogwiritsira ntchito (chisangalalo ndi katundu) wa gulu loyesera (UUT: Unit Under Test), kotero kuti imagwira ntchito m'madera osiyanasiyana apangidwe, kuti apeze magawo a dziko lililonse. kutsimikizira UUT Njira yoyesera ya ntchito yabwino kapena yoyipa.Mwachidule, ndikukweza UUT ndi chilimbikitso choyenera kuti muyese ngati kuyankha kwake kuli kokhutiritsa.
11, kuyimira mayeso okalamba
The okalamba mayeso maimidwe akhoza kuyesa bolodi PCBA mu magulu, ndi kuyesa zovuta PCBA bolodi ndi simulating ntchito wosuta kwa nthawi yaitali.
