Moetsi oa Tlholisano ea PCB

SMT ke khutsufatso ea Surface Mounted Technology, theknoloji e tsebahalang haholo le ts'ebetso indastering ea kopano ea elektroniki.Electronic circuit Surface Mount Technology (SMT) e bitsoa Surface Mount kapa Surface Mount Technology.Ke mofuta oa theknoloji ea kopano ea potoloho e kenyang likarolo tsa kopano e se nang lead kapa e khuts'oane (SMC/SMD ka Sechaena) holim'a Printed Circuit Board (PCB) kapa bokaholimo bo bong ba substrate, ebe e tjheseletsa le ho bokana ka ho cheseletsa kapa kolobisa welding.

Ka kakaretso, lihlahisoa tsa elektroniki tseo re li sebelisang li entsoe ka PCB hammoho le li-capacitor tse fapaneng, li-resistors le likarolo tse ling tsa elektroniki ho latela setšoantšo sa potoloho, kahoo mefuta eohle ea lisebelisoa tsa motlakase e hloka theknoloji e fapaneng ea ho sebetsa chip ea SMT.

Likarolo tsa mantlha tsa ts'ebetso ea SMT li kenyelletsa: khatiso ea skrineng (kapa ho fana), ho kenya (ho folisa), ho tjheseletsa, ho hloekisa, ho etsa liteko, ho lokisa.

1. Ho hatisa skrineng: Mosebetsi oa ho hatisa skrineng ke ho lutla sekhomaretsi sa solder kapa sekhomaretsi holim'a pampiri ea solder ea PCB ho itokisetsa ho cheselletsa likarolo.Thepa e sebelisoang ke mochine oa khatiso oa skrine (mochini oa khatiso oa skrine), o karolong e ka pele ea mohala oa tlhahiso ea SMT.

2. Sekhomaretsi fafatsa: E theola sekhomaretsi ho boemo bo tsitsitseng ba boto ea PCB, 'me mosebetsi oa eona o ka sehloohong ke ho lokisa likarolo ho boto ea PCB.Thepa e sebelisoang ke mochini o tsamaisang thepa, o pheletsong e ka pele ea mohala oa tlhahiso ea SMT kapa ka morao ho lisebelisoa tsa tlhahlobo.

3. Thaba: Mosebetsi oa eona ke ho kenya likarolo tsa kopano ea holim'a metsi ka nepo ho boemo bo tsitsitseng ba PCB.Thepa e sebelisoang ke mochini oa ho bea oa SMT, o ka morao ho mochini oa khatiso oa skrine moleng oa tlhahiso ea SMT.

4. Ho phekola: Mosebetsi oa eona ke ho qhibilihisa sekhomaretsi sa SMT e le hore likarolo tsa kopano ea holim'a metsi le boto ea PCB li ka khomarela ka thata hammoho.Thepa e sebelisoang ke ho folisa sebōpi, se ka morao ho mohala oa tlhahiso ea SMT SMT.

5. Reflow welding: mosebetsi oa reflow welding ke ho qhibiliha peista ea solder, e le hore likarolo tsa kopano le PCB li khomarele ka tieo.Thepa e sebelisoang ke sebōpi sa reflow welding, se moleng oa tlhahiso ea SMT ka mor'a mochine oa ho beha SMT.

6. Ho hloekisa: Mosebetsi ke ho tlosa masala a tjheseletsa a kang flux ho PCB e kopaneng e kotsi ho 'mele oa motho.Thepa e sebelisoang ke mochini oa ho hloekisa, boemo bo ke keng ba lokisoa, bo ka ba inthaneteng, kapa che.

7. Ho lemoha: E sebelisetsoa ho lemoha boleng ba tjheseletsa le boleng ba kopano ea PCB e bokaneng.Thepa e sebelisoang e kenyelletsa likhalase tse holisang, microscope, sesebelisoa sa tlhahlobo ea marang-rang (ICT), sesebelisoa sa tlhahlobo ea nale e fofang, tlhahlobo ea optical optical (AOI), sistimi ea tlhahlobo ea X-ray, sesebelisoa sa tlhahlobo ea ts'ebetso, joalo-joalo. Sebaka se ka hlophisoa ka mokhoa o nepahetseng. karolo ea mohala oa tlhahiso ho latela litlhoko tsa tlhahlobo.

8.Repair: e sebelisoa ho tsosolosa PCB e fumanoeng ka liphoso.Lisebelisoa tse sebelisoang ke litšepe tsa soldering, li-workstations tsa ho lokisa, joalo-joalo. Sebopeho se teng kae kapa kae moleng oa tlhahiso.
