IRigid Flex PCB Manufacturing

Ngaba ukunyuka kwezinto eziluhlaza kunempembelelo enkulu kwixabiso lokwenziwa kwe-flex eqinilePCBiibhodi?Ukusukela ngoSeptemba ka-2020, ukuza kuthi ga ngoku, iCCL-clad laminates ziye zafumana imijikelo emininzi yokunyuka kwamaxabiso.Xa kuthelekiswa nenqanaba eliphantsi ngo-2020, amaxabiso angoku kwezinye iimveliso zebhodi ehle kabini.Lo mjikelo wokunyuka kwexabiso kunokuthiwa lolona lwando lukhulu kwieqinile flex PCB yokuvelisaishishini kule minyaka ili-10 idlulileyo.Kutheni i-laminate yobhedu iqhubeka nokunyuka kwexabiso?

Sikholelwa ukuba ikakhulu kubangelwa ezi nkalo zintathu zilandelayo: inkalo yokuqala ngenxa yokunqongophala kwezinto eziluhlaza kwindawo ephezulu yekhonkco yoshishino lwe-copper clad laminate kunye nokunyuka kwexabiso;umba wesibini kungenxa yemfuno emandla kumazantsi e-flex flex PCB ikhonkco loshishino lokuvelisa;umba wesithathu ngowokuba Ngenxa yeNtsholongwane, uqoqosho olukhulu lunemali ekhutshwe ngokugqithisileyo, okukhokelela ekunyukeni kwamaxabiso.Iimathiriyeli ekrwada ye-CCL ubukhulu becala yenziwe ngobhedu, i-glass fiber kunye neresin.

Ukunyuka kwamaxabiso eentlobo ngeentlobo zemathiriyeli ekrwada kumantla omlambo kudlale indima ekukhuthazeni ukunyuka kwamaxabiso eelayithi ezigqunywe ngobhedu.Phakathi kwezinto ezibonakalayo ze-CCL, i-foil yobhedu i-akhawunti ye-30% -50%, i-fiber ye-glass fiber i-25% -40%, kunye ne-resin i-akhawunti ye-25% -30% yeendleko zizonke.Kuyaqondwa ukuba amandla okuvelisa ifoyile yobhedu enyukayo yeelaminayithi ezigqunywe ngobhedu anqongophele ngoku.Ukuchaphazeleka ngokuqhambuka kweshishini elitsha lemoto yamandla, iqela labavelisi be-PCB be-flex flex batshintshele kwi-lithium ibhetri ye-copper foil, okubangele i-gap enkulu yokubonelela nge-foil yobhedu ye-elektroniki kunye nokunyuka ngokukhawuleza kwamaxabiso.Ukongeza, ezona zixhobo ziphambili ze-foil substrates zobhedu, ezifana nefiber yeglasi kunye neresin, ziye zanda kakhulu ukuya kuthi ga kwi-30% -100%.Kwelinye icala, ukonyuka okukhulu kwemfuno esezantsi yomjelo kwikhonkco leshishini le-laminate ene-copper-clad efana ne-electronics yabathengi, izikhululo ezisisiseko ze-5G, kunye ne-automotive electronics ikwayeyona nto iphambili eqhuba ukunyuka kwamaxabiso eepleyiti zobhedu.

Ukuthatha esona sicelo siphambili sePCBkumlambo osezantsi laminates zobhedu evathe njengomzekelo, ukususela kwisiqingatha sesibini kunyaka ophelileyo, imfuno kwiinkalo ezahlukeneyo ezantsi komsinga engqongqo flex PCB yokuvelisa iye yangena kwixesha ukuchacha ngokukhawuleza, de imeko yangoku yokunyuka kwempumelelo iyaqhubeka.Nangona kunjalo, umjikelo wesibini wokunyuka kwexabiso unempembelelo encinci kwiindleko zokusetyenzwa kweebhodi ze-PCB eziqinileyo.Esona sizathu sibalulekileyo kukuba, ngenxa yokwakhiwa kweendleko zokwenziwa kwebhodi yePCB eguquguqukayo, umyinge wezinto zamaphepha uphantsi kakhulu.Ukuthatha iezine umaleko engqongqo flex ibhodi PCBnjengomzekelo, i-CCL ibala ngaphantsi kwe-5% yeendleko ezipheleleyo, kwaye iindleko eziphambili zokuvelisa ibhodi ye-flexible eqinile ivela kwiindleko zayo eziyinkimbinkimbi.Kodwa imeko yeebhodi eziqinileyo eziqhelekileyo zichasene ngokupheleleyo.Ukuthatha iipaneli eziqhelekileyo ezinamacala aphindwe kabini njengomzekelo, umlinganiselo wephepha lesinyithi uphezulu ukuya kuma-30-40%, kunye nesiqhelo.iibhodi ezine umalekoiphezulu njenge 20-30%.

Ngakolunye uhlangothi, kubangelwa ukuba iindleko ezipheleleyo zeebhodi eziguquguqukayo azizange ziphakame kakhulu.Njengoko sonke siyazi: izinto ezisisiseko zebhodi eguquguqukayo yi-FCCL, kunye nezona zinto ziphambili ze-FCCL: ifilimu ye-polyester (PET) kunye ne-polyimide (PI) ifilimu.Xa kuthelekiswa ne-resin kunye ne-glass fiber cloth, ezi zixhobo azinyukanga kakhulu, kwaye ngenxa yokuba i-FCCL incinci kakhulu kune-CCL, inani lezinto ezifunekayo ezifunekayo lincinci, ngoko ke ixabiso elipheleleyo leebhodi eziguquguqukayo alinyukanga kakhulu.Ezi zizathu zibini zingasentla zinokuchaza ukuba kutheni nangona ukunyuka kwe-sheet metal kuya kwandisa ixabiso lebhodi eqinile nge-15-30%, ixabiso lebhodi ye-PCB eqinile ayinakunyuswa.
