Kukho utshintsho olutsha kwi-adhesives, njengokusebenzisa i-AI kunye ne-IoT. Abantu abaninzi bafuna izixhobo eziguquguqukayo ngoku. Hlala ulandela imigaqo kwaye ucele iingcali ukuba zifumane iziphumo ezilungileyo.
FAQ
Yeyiphi into encamathelayo isebenza kakuhle kwiiPCB ezibhetyebhetye?
I-Adhesives ye-Acrylic ilungile kuninzi iiPCB ezibhetyebhetye. I-Acrylics igoba kwaye igcine iibhodi zomelele. I-epoxy adhesives ingcono kwiindawo eziqinileyo. Izincamathelisi zeSilicone zinceda kwiindawo ezishushu kakhulu okanye ezibandayo.
Uvavanya njani amandla okuncamathelisa kwiisekethe eziguquguqukayo?
Ungasebenzisa uvavanyo lwamandla e-peel. Olu vavanyo lubonisa indlela i-adhesive ebamba ngayo ubhedu. Utsala iileya ngokwahlukeneyo kwaye ubone ukuba kuthatha amandla angakanani.
Ngaba unokusebenzisa izinto zokuncamathelisa ezinoxinzelelo kwiibhodi ezinobushushu obuphezulu?
Hayi, musa ukusebenzisa izinto ezincamathelayo ezinoxinzelelo kwiibhodi ezishushu. Ezi zinto zincamathelayo ziba buthathaka xa zisiba shushu. Izinto zokuncamathelisa iThermosetting zisebenza ngcono xa kushushu.
Yeyiphi imigangatho ekuncedayo ukuba ukhethe izinto ezincamathelayo kwiiPCB ezibhetyebhetye?
Kufuneka usebenzise i-IPC-6013 kunye nemigangatho ye-IPC-4203. Le migaqo ikunceda ukuba ukhethe i-adhesives ekhuselekileyo kwiibhodi zeesekethe eziguquguqukayo.
Ngaba zonke izinto zokuncamathelisa zisebenza nge-polyimide kunye ne-PET substrates?
Ayizizo zonke i-adhesive ezihambelana ne-substrate yonke. Kufuneka ujonge ukuba ziyahambelana na phambi kokwakha. I-epoxy, i-acrylic, kunye ne-silicone adhesives zihlala zisebenza nge-polyimide kunye ne-PET.
