Ii-laminate sheets zeglasi yefayibha ye-FR4 zahlukile ngenxa yokudibanisa kwazo iimpawu ezikhethekileyo, nto leyo eyenza zilungele kakhulu ukusetyenziswa okubanzi. Apha ngezantsi, ndiza kujonga iinkalo ezahlula i-FR4 kwezinye izinto.

Ukubunjwa kunye neempawu

Amaphepha eFrame Resistance FR4 amele udidi olukhethekileyo lwezixhobo eziyahlulahlula ngokubunjwa kwazo kunye neempawu ezihlukeneyo, ukuzibeka ngaphandle kwezinye izinto eziqhelekileyo eziqeshwe kwi-insulation yombane kunye nebhodi yesekethe eprintiweyo (PCB). Ukuqonda ukubunjwa kunye neempawu eziphambili zamaphepha e-FR4 kunceda ukuxabisa izibonelelo zabo zokuthelekisa kunye nezicelo ezinxulumene nezinye izixhobo. Oku kucaciswa kuphonononga ukubunjwa kunye neempawu zamaphepha eFR4, zithelekiseka nezinye izinto ukuze kugxininiswe ukongama kwazo ngokwendalo.

• ukwakhiwa

Amaphepha e-FR4 abandakanya ikakhulu i-epoxy resin efakwe kwi-fiberglass eqinisiweyo, ecwangciswe ngokwemigangatho emininzi okanye iiplies. I-epoxy resin isebenza njengento ye-matrix, inika amandla omatshini, ukunamathela, kunye neempawu zokugquma umbane eziyimfuneko kwisakhiwo se-laminate. Ukuqiniswa kwe-fiberglass, okubandakanya iintambo zeglasi ezifakwe ngaphakathi kwe-resin matrix, yongeza amandla okuqina, ukuqina okuguquguqukayo, kunye nokuchasana ne-delamination, ukunika ukuqina kunye nokuzinza komda kwi-laminate.

Ukongeza kwi-epoxy resin kunye ne-fiberglass reinforcement, amaphepha e-FR4 angabandakanya izongezo ze-flame-retardant zokwandisa ukumelana nomlilo kunye nokuthotyelwa kwemigangatho yokhuseleko. Ezi zongezo, ezifana ne-brominated flame retardants okanye i-phosphorus-based compounds, ukunciphisa ukusasazeka kwamadangatye kunye nokunciphisa ukukhutshwa komsi ngexesha lokuvezwa komlilo, ukuphucula ukhuseleko kunye nokuthembeka kwezixhobo zombane kunye neendawo ezivaliweyo.

• iimpawu

Ukumelana neLanga: Uphawu olucacileyo lweeshiti ze-laminate zeglasi yefayibha ye-FR4 kukumelana kwazo okubalaseleyo nelangatye, okubangelwa kukufakwa kwezongezo ezithintela umlilo. Ngokungafaniyo nezinto eziqhelekileyo ezifana nee-laminate ze-phenolic ezisekelwe ephepheni okanye ii-thermoplastics, iishiti ze-FR4 azinawo amandla okutsha kwaye azicimi ngokwazo, zinciphisa iingozi zomlilo kwaye ziqinisekisa ukuthotyelwa kwemigaqo yokhuseleko engqongqo.

I-Insulation yoMbane: Amaphepha e-FR4 aqhayisa iipropati eziphezulu zokugquma umbane, ezibonakaliswe ngamandla aphezulu e-dielectric, i-low dissipation factor, kunye nokungabonakali kumswakama kunye nomswakama.

Amandla oomatshini: Ukudityaniswa kwe-epoxy resin matrix kunye ne-fiberglass yokuqinisa inika amandla omatshini aqinileyo kwi-FR4 laminate sheets, ukodlula ezo zemathiriyeli ezifana ne-acrylic, nayiloni, okanye i-phenolic laminates. Amaphepha e-FR4 abonisa amandla aphezulu okuxinana, imodyuli eguquguqukayo, kunye nokuchasana kwempembelelo, okubenza bakwazi ukumelana noxinzelelo lomatshini, ukungcangcazela, kunye nokuhamba ngebhayisekile okushushu okudityaniswe neendawo ezifuna indawo yeshishini.

Ukuzinza kweDimensional: Amaphepha e-laminate e-FR4 abonisa ukuzinza kwe-dimensional okugqwesileyo kuluhlu olubanzi lobushushu, izinto ezigqwesileyo ezifana ne-polyethylene okanye i-polypropylene. Uzinzo lwe-thermal yendalo ye-epoxy resin kunye ne-fiberglass reinforcement kunciphisa ukwanda kunye nokucutha kwe-thermal, iqinisekisa ukubhaliswa okuchanekileyo kweeleyile ze-PCB kunye nokusebenza okuthembekileyo kwizicelo ezinobushushu bobushushu.

Ukumelana neMichiza: Amaphepha e-FR4 abonisa ukuchasana kweekhemikhali eziphezulu xa kuthelekiswa nezinto ezifana ne-laminates esekelwe ephepheni okanye i-thermoplastics. Ubume be-inert ye-epoxy resin kunye ne-fiberglass reinforcement inika ukuxhathisa kuluhlu olubanzi lweekhemikhali, izinyibilikisi, kunye ne-ejenti ezonakalisayo, ziqinisekisa ukuqina kunye nokuphila ixesha elide kwiindawo ezinzima zemizi-mveliso.

Isishwankathelo, i-Flame Resistance FR4 i-fiberglass laminate sheets ime ngaphandle kwezinye izinto ngenxa yokwakheka kwazo ezizodwa kunye neempawu ezikhethekileyo, kubandakanywa ukuxhathisa idangatye, ukugqunywa kombane, amandla omatshini, ukuzinza kwe-dimensional, kunye nokumelana neekhemikhali. Ezi mpawu zahlukileyo zenza amaphepha eFR4 abe yimfuneko kwimilidingwane yezicelo kubunjineli bombane, ukwenziwa kombane, kunye namacandelo emizi-mveliso, kugxininiswa ukusetyenziswa kwawo okungenakuthelekiswa nanto kunye nokuguquguquka kwezinto ezininzi kubuchwephesha banamhlanje kunye nokuyila.

 

Iipropati zoomatshini kunye ne-Thermal

Amaphepha e-FR4 abonisa amandla abalaseleyo omatshini kunye nokuzinza kwe-thermal, ekwazi ukujamelana namaqondo okushisa aphezulu ngaphandle kokuthotywa, okuyimfuneko kwizicelo ezibandakanya ukubonakaliswa kobushushu njengombane kunye ne-amplifiers. Ngokuqhelekileyo zisebenza kuluhlu lobushushu obuphakathi kwe -40°C ukuya kwi-130°C kwaye zineeglasi eziphezulu zokutshintsha ubushushu, ziqinisekisa uzinzo kuluhlu lweemeko(Atlas Fibre)​(FR4 Material).

 

Ukufakwa kombane

Esinye sezizathu eziphambili zokuba iFR4 ithandwa kushishino lombane kukugquma kwayo kombane okugqwesileyo. Inamandla aphezulu e-dielectric kunye ne-dielectric eguquguqukayo ephantsi, eyenza ukuba ikwazi ukwahlula ngokufanelekileyo izixhobo zombane kunye nokuthintela ukuphazamiseka kombane, okubalulekileyo ukugcina imfezeko kunye nokusebenza kwezixhobo zombane (Elecrow).
