Npog daim kab xev yog tsuas yog siv nyob rau hauv cov khoom siv hluav taws xob tso rau hauv kev lag luam.Nws yog siv ua ke nrog ib daim kab xev nqa los nqa thiab khaws cov khoom siv hluav taws xob xws li resistors, capacitors, transistors, diodes, thiab lwm yam.
Daim kab xev npog feem ntau yog ua los ntawm polyester lossis polypropylene zaj duab xis, thiab yog sib xyaw lossis coated nrog cov txheej txheem ua haujlwm sib txawv (txheej txheej tiv thaiv zoo li qub, txheej nplaum, thiab lwm yam).Thiab nws tau muab khi rau saum lub hnab tshos hauv daim kab xev nqa khoom los tsim qhov chaw kaw, uas yog siv los tiv thaiv cov khoom siv hluav taws xob los ntawm kev sib kis thiab kev puas tsuaj thaum thauj.
Thaum muab cov khoom siv hluav taws xob tso, daim kab xev npog raug tshem tawm, thiab cov khoom siv tsis siv neeg muab tso rau hauv lub hnab tshos los ntawm qhov sprocket qhov ntawm cov cab kuj daim kab xev, thiab tom qab ntawd siv thiab muab tso rau ntawm lub rooj sib tham sib koom ua ke (PCB board) nyob rau hauv ib txwm.
Classification ntawm cover tapes
A) Los ntawm qhov dav ntawm daim kab xev npog
Yuav kom phim qhov dav dav ntawm cov cab kuj, cov kab xev npog yog ua nyob rau hauv ntau qhov dav.Cov dav dav yog 5.3 hli (5.4 hli), 9.3 hli, 13.3 hli, 21.3 hli, 25.5 hli, 37.5 hli, thiab lwm yam.
B) Los ntawm cov yam ntxwv sealing
Raws li cov yam ntxwv ntawm kev sib txuas thiab tev tawm ntawm cov kab xev cab, cov ntaub npog npog tuaj yeem muab faib ua peb hom:Thaum tshav kub kub-activated daim kab xev (HAA), siab-rhiab daim kab xev (PSA), thiab tshiab universal npog daim kab xev (UCT).
1. Heat-activated cover tape (HAA)
Lub sealing ntawm lub tshav kub-activated npog daim kab xev yog ua tiav los ntawm tshav kub thiab siab los ntawm lub sealing thaiv ntawm lub tshuab sealing.Thaum cov nplaum nplaum kub yaj yog yaj rau ntawm qhov chaw sib khi ntawm daim kab xev, daim kab xev npog yog compressed thiab kaw rau daim kab xev cab.Lub tshav kub-activated daim kab xev tsis muaj viscosity ntawm chav tsev kub, tab sis ua nplaum tom qab cua sov.
2.Pressure rhiab nplaum nplaum (PSA)
Lub sealing ntawm lub siab-rhiab daim kab xev yog ua los ntawm lub tshuab sealing siv lub siab nruam los ntawm lub siab cov menyuam, yuam lub siab-rhiab nplaum nplaum ntawm daim kab xev rau daim kab xev rau daim kab xev.Ob sab nplaum ntug ntawm lub siab-rhiab daim kab xev yog nplaum ntawm chav tsev kub thiab siv tau yam tsis muaj cua sov.
3. New Universal Cover Tape (UCT)
Lub zog tev tawm ntawm lub npog tapes ntawm kev ua lag luam feem ntau yog nyob ntawm lub zog nplaum ntawm cov kua nplaum.Txawm li cas los xij, thaum tib cov kua nplaum siv nrog cov khoom sib txawv ntawm cov kab xev cab, cov nplaum nplaum sib txawv.Lub zog nplaum ntawm cov kua nplaum kuj txawv nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias.Tsis tas li ntawd, tej zaum yuav muaj kab mob ntawm cov kua nplaum seem thaum tev.
Txhawm rau daws cov teeb meem tshwj xeeb no, ib hom tshiab ntawm universal npog daim kab xev tau qhia rau lub khw.Lub zog tev tawm tsis tso siab rau lub zog nplaum ntawm cov kua nplaum.Hloov chaw, muaj ob qhov sib sib zog nqus grooves txiav ntawm lub hauv paus zaj duab xis ntawm daim kab xev npog los ntawm kev ua kom raug txhua yam.
Thaum tev, lub npog daim kab xev lub kua muag raws grooves, thiab tev tawm yog ywj siab ntawm cov nplaum quab yuam ntawm cov kua nplaum, uas tsuas yog cuam tshuam los ntawm qhov tob ntawm cov grooves thiab lub zog txhua yam ntawm zaj duab xis, thiaj li yuav ua kom muaj kev ruaj ntseg. lub zog peeling.Tsis tas li ntawd, vim tias tsuas yog qhov nruab nrab ntawm daim kab xev npog tsuas yog tev tawm thaum lub sij hawm tev, thaum ob sab ntawm daim kab xev npog tseem ua raws li cov kab sib khi ntawm cov cab cab, nws kuj txo cov kab mob ntawm cov kua nplaum uas seem thiab cov khib nyiab rau cov khoom siv thiab cov khoom siv. .
