Farashin SMD
Faci na SMT yana nufin taƙaita jerin matakai da aka sarrafa bisa PCB.PCB (Printed Circuit Board) allo ne da aka buga.
SMT shine Fasahar Dutsen Surface (Surface Mount Technology) (ƙarshen fasahar da aka fi sani da Surface Mounted Technology), wanda shine mashahurin fasaha da tsari a cikin masana'antar hada kayan lantarki.
Fasahar haɗuwa da kewayen lantarki (Surface Mount Technology, SMT), wanda aka sani da dutsen ƙasa ko fasahar ɗorawa.Wani nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'in nau'i ne (SMC/SMD a takaice, Sinanci da ake kira guntu sassa) wanda aka ɗora a saman allon da'irar da aka buga (Printed Circuit Board, PCB) ko saman sauran kayan aiki, ta hanyar haɗin kewayawa da fasahar haɗin haɗin da ake siyarwa kuma ana haɗa su ta hanyoyi kamar reflow soldering ko dip soldering.
A cikin yanayi na yau da kullun, samfuran lantarki da muke amfani da su PCB ne suka kera su tare da capacitors daban-daban, resistors da sauran kayan lantarki bisa tsarin da aka tsara, don haka kowane nau'in kayan lantarki suna buƙatar fasahar sarrafa guntu iri-iri na SMT don sarrafawa, Ayyukansa shine. leak solder manna ko facin manne akan pads na PCB don shirya don sayar da abubuwan da aka gyara.Kayan aikin da aka yi amfani da shi shine na'urar buga allo (na'urar buga allo), wanda ke kan gaba a layin samar da SMT.
Tsarin asali na SMT
1. Buga (bugun siliki): Ayyukansa shine buga manna solder ko facin liƙa akan pads na PCB don shirya don siyarwar abubuwan da aka gyara.Kayan aikin da aka yi amfani da shi shine na'urar buga allo (na'urar buga allo), wanda ke kan gaba a layin samar da SMT.
2. Glue dispensing: Shi ne ya sauke manna a kan kafaffen matsayi na PCB, kuma babban aikinsa shi ne gyara abubuwan da ke cikin allon PCB.Kayan aikin da aka yi amfani da shi shine mai rarraba manne, wanda ke kan gaba na layin samar da SMT ko a bayan kayan gwaji.
3. Hawan: Ayyukansa shine shigar da daidaitattun abubuwan hawan saman saman zuwa tsayayyen matsayi na PCB.Kayan aikin da aka yi amfani da shi shine na'ura mai sanyawa, wanda ke bayan na'urar buga allo a cikin layin samar da SMT.
4. Curing: Ayyukansa shine narke mannen faci, ta yadda abubuwan da ke saman dutsen da kuma allon PCB suna da alaƙa da juna.Kayan aikin da aka yi amfani da shi shine tanda mai warkewa, wanda ke bayan injin sanyawa a cikin layin samar da SMT.
5. Reflow soldering: Its aiki ne don narke solder manna, sabõda haka, da surface Dutsen aka gyara da PCB jirgin suna da tabbaci bonded tare.Kayan aikin da aka yi amfani da shi shine tanda mai sake kwarara / siyarwar igiyar ruwa, wanda ke bayan injin sanyawa a cikin layin samarwa na SMT.
6. Tsaftacewa: Aikinsa shine cire ragowar walda masu cutarwa ga jikin ɗan adam kamar jujjuyawa akan allon PCB da aka haɗa.Kayan aikin da ake amfani da su injin wanki ne, kuma ba za a gyara wurin ba, akan layi ko a layi.
7. Dubawa: Ayyukansa shine duba ingancin walda da ingancin taro na kwamitin PCB da aka taru.Kayan aikin da aka yi amfani da su sun haɗa da gilashin ƙararrawa, na'urar microscope, mai gwadawa ta kan layi (ICT), gwajin gwaji mai tashi, dubawa ta atomatik (AOI), tsarin dubawa na X-RAY, gwajin aiki, da dai sauransu. Ana iya saita wurin a wuri mai dacewa akan layin samarwa. bisa ga bukatun ganowa.
Tsarin SMT na iya inganta ingantaccen samarwa da daidaiton kwamfutocin da'irar da aka buga, kuma da gaske gane sarrafa kansa da samar da taro na PCBA.
Zaɓin kayan aikin samarwa wanda ya dace da ku sau da yawa ana iya samun sakamako sau biyu tare da rabin ƙoƙarin.Chengyuan Industrial Automation yana ba da taimako da sabis na tsayawa ɗaya don SMT da PCBA, kuma yana shirya muku tsarin samarwa mafi dacewa.
