Chidziwitso cha mzere wa SMT/PCB

Shenzhen Chengyuan Industrial Automation Equipment Co., Ltd. imapereka mayankho akatswiri ndi zida zodzichitira okha pamizere yanzeru yopanga fakitale ya SMT.

SMT mounter, lead-free reflow soldering, lead-free wave soldering, PCB conformal kupaka utoto makina, makina osindikizira, kuchiritsa uvuni.

Palibe kukayika kuti bolodi losindikizidwa (PCB) ndi chida champhamvu kwambiri paukadaulo wamunthu.

PCBs akhala njira optimizing ndondomeko kupanga zipangizo zamagetsi.M'mbuyomu, zida zamagetsi zomangidwa ndi manja izi zidayenera kusinthidwa ndi matabwa osindikizidwa.Izi ndichifukwa choti ntchito zambiri zidzaphatikizidwa pa bolodi.

Yerekezerani gulu lozungulira la chowerengera cha 1968 ndi bolodi lamakompyuta amakono.

1. Mtundu.

Ngakhale kwa anthu ena omwe sadziwa kuti PCB ndi chiyani, nthawi zambiri amadziwa momwe PCB imawonekera.Amawoneka ngati ali ndi mtundu umodzi wachikhalidwe, womwe ndi wobiriwira.Chobiriwira ichi kwenikweni ndi mtundu wowonekera wa solder mask galasi utoto.Ngakhale dzina la chigoba cha solder ndi solder mask, ntchito yake yayikulu ndikuteteza dera lophimbidwa kuchokera ku chinyezi ndi fumbi.

Ponena za chifukwa chake chigoba cha solder ndi chobiriwira, chifukwa chachikulu ndi chakuti zobiriwira ndizo chitetezo cha asilikali.Kwa nthawi yoyamba, ma PCB mu zida zankhondo agwiritsa ntchito masks ogulitsidwa m'munda kuteteza kudalirika kwa dera.

Masks a solder tsopano akupezeka mumitundu yosiyanasiyana, kuphatikiza yakuda, yofiira, yachikasu, ndi zina zambiri.Kupatula apo, zobiriwira sizinthu zamakampani.

2. Ndani adayambitsa PCB?

Mabodi oyambirira osindikizidwa amatha kutsatiridwa ndi injiniya wa ku Austria Charles Ducas mu 1920, yemwe anapereka lingaliro la kuyendetsa magetsi ndi inki (kusindikiza mawaya amkuwa pansi pa mbale).Anagwiritsa ntchito ukadaulo wa electroplating kupanga mawaya mwachindunji pamwamba pa insulator ndikupanga chithunzi cha PCB.

Mawaya achitsulo pama board ozungulira anali mkuwa, aloyi yamkuwa ndi zinki.Kupanga kosokoneza kumeneku kumathetsa njira yovuta yolumikizira mawaya amagetsi, kuonetsetsa kudalirika kwa magwiridwe antchito.Njirayi sinalowe mu gawo lothandizira mpaka kumapeto kwa Nkhondo Yadziko II.

3. Maliko.

Pali zoyera zambiri pa bolodi yobiriwira yobiriwira.Kwa zaka zambiri, anthu sankamvetsetsa chifukwa chake zojambula zoyerazi zimatchedwa "silkscreen layers".Amagwiritsidwa ntchito makamaka kuti azindikire zidziwitso zamagulu pa bolodi ladera ndi zina zokhudzana ndi gulu ladera.Izi zitha kuthandiza mainjiniya ozungulira kuyang'ana bolodi ngati ili ndi zolakwika.
